DIY RFID Beer Safe
Monday, November 3rd, 2008 running time 31:35
Dave and Pat break down the basics of RFID technology and show you how to put it to use by building an RFID beer safe!
RFID, or Radio Frequency ID, is everywhere: key cards in office buildings, electronic tollbooths and even passports. But how do you take that technology and use it for something a little more personal?
Today on Systm we will be looking at how RFID technology works and demonstrate one possible use for around the home by building our very own RFID-enabled beer safe. It's just the thing to keep your brew safe from thirsty and inconsiderate roommates, friends or even in-laws!
Of course you can't walk into any Radio Shack or electronics store and buy RFID gear off the shelf. You'll probably have to get most of the gear online and two of the best places to do that are APSX and Trossen Robotics. Both offer Parallax's BASIC Stamp programming board that David uses in this episode. The kits will run around $100 but provide pretty much everything you need to get started. You'll also find RFID readers, servos, and tags you'll need to complete this project. Jameco is also an excellent source. If you're not sure how to program the board, don't worry - the manuals that ship with the kit are pretty straight forward. Plus Trossen Robotics provides excellent support if you have any issues with the gear.

" Wow. Today's system the sponsored by the united states air force that flicks and GoDaddy got cop. -- and -- chipset for pets key cards for the office or newfangled passports RFIDs are everywhere. But exactly how they work in what could use them for home. Today we're gonna bring it all down for him everything from how RFIDs actually work to assembling your own RFID system and incorporating it into something practical. Or something actually kind of in practical like a beer locker for your fridge. One that only a lot when you wait to correct RFID card in front of it denying those less worthy such as your different up only about unemployed brother in law's from act. Accessing the beer inside. Are fighting 11 and building her own -- locker on this episode. System. Well this system I'm Patrick Norton and I and it Calkins. Radio frequency and it."
" Patient is really neat little piece of technology with a whole lot of uses any key current electronic toll systems and -- things. Yes our rhetorical perfect perfect well lets them from Minnesota where we really -- like pronounce her accident. So it's -- perfect -- you know and you know sometimes I need to know her we you know its -- editors -- curator and I actually what it. You got some old whose and he gives me you know who. Now before the email -- pouring in from Minnesota he actually is committed Soviet and -- Minnesota via an exclusive duplicate media being so. Bad streeters tags inventory Wal-Mart -- he's put in the like everything they buy from every company in the planet. Yeah tracking purposes for tracking purposes so there's both the whole lake. Don't steal -- thing but there's also the tracking purposes you know like. What happened to you know two shipments is stolen truck somewhere but it is basically -- you have a guy without you doing physical inventory is check. Track checked in overnight literally just walking by death talent and it was."
" And building building building."
" This is not -- with liquid in the house which blocks the architect response or can interest trees -- you know. I mean they're actually US passports now actually -- have RID tags yes which unfortunately you know every technology can be used for good or evil. Architects."
" AA in -- passports you know can be definitely used for evil because basically. The terrorists probably you're gonna get more usage out of architects because I can walk by you know. Random tourists that are for readers such as this one in my pocket. And find out if you're an American or Canadian -- in the -- has to be -- somebody's gonna Flexilis who -- isn't it pretty decent -- Jon on better readers. You're -- about customizing these devices yet the nice thing about. Our kids now is is they're cheap enough and they're multi so basically like I have in my very quality hear them. I have to activity feed to the workshop. And RFID card you know I never actually take it out of my wallet I actually just -- but against the reader. And it's red and it's just -- dumb little plastic art. Now if you're gonna use something like this at home you don't actually need to buy a second RFID. So one of the things you could do is use an Arctic reader like this -- him on and use your existing work card. And you just program the most micro controller usury existing work hard to recognize. This card. And know open your door opener for a curator let the dog out you know every one. So in the long run you know years from now you might have one RFID card which is -- to your person. And then opens up both here worked or -- cargo lower your home two hours. Article that -- get fired and you speak your ID -- from work here you log into your house. Well because you're controlling your house basically -- which -- really control and this is where re programmable RFID tags come into play is is that basically something like that. Can be used you know for multiple purposes in this case in my program this micro controller to recognize that RFID. Serial number. I can use it for anything now if work takes away all I have to do is get every programmable one. That record with the same number on it and then I'm still using an excellent. Book and so we -- what other type of orchid tag. What other types I mean there's a million different search."
" Does so I've got sent here if -- into the -- And fuel and fuel. I just like -- when you you -- ones so I got this from trust her products from. And we we paid wrote retails so this plugin it -- because -- give him free. Why things -- really like about. Trust and is that there. Customer service is really top notch you know if you call them up and say hey. I want to order this little twenty dollar package RFID sampler -- it just is gonna service as if you're saying hi. I'm placing -- 20000 dollar. I'll order for all sorts -- RFID -- the few companies -- dealt with in all -- research. That is always just absolutely top notch it is in their customer service and the same goes for her elects the other brand of reason these experiments. I'm is both of these guys they have. Awesome web sites with sample code sample products all sorts of things that you have to just byproduct and then. Right all of your own code there's all sorts of stuff is really easy to modify I -- the best part about this is there any special note that these and you'll have."
" Not been handled in aid medical manner and they've not been sterilized and therefore you should not inject them into people so that's."
" This one here for example is probably what is in your dog if you have a good German shepherd and you haven't RFID. And fuel in your dog it's probably one just like this it's that the little case is not the little one. And for all those people who want to -- experimentation with RFID and fuels. The real issue isn't that you should be worried about putting in this passive. Little antenna in your skin the real issue that you should do this at home is simply put that you probably don't know how to sterilize yourself the end fuels. Or -- cutting materials properly. Now well gangrene. Treatments have progressed quite a bit since the nineteenth century. I. Really strongly advised against trying to implement one of these in your own skin yeah I mean you have to so yourself that and I mean really people are becoming queasy about structuring."
" Wired the sequence so. Why is this once will be used an extra memory yourself members at a stronger signal one is regrettable one's one's right I mean only. So this one's the read only with a single number on this will be the regrettable. This one's right -- how much information can you actually right."
" It's not a lot so. Basically your rating. Text string it's a single -- a single -- it's not a lot of data it's basically just it's one of those. Encoding so if you want to say hi my name is now 123456. Rather than my old name being 123123. Kind of thing. Here industry -- so it's not what of these things where you're really implanting you know. Name address serial number the better kind and you can buy stuff that will do that okay. The off the shelf you know dollar market tank is not the kind of story that much memory yes there are. Industrial sized. You know architects and -- size enough hugging about the actual size of the -- idea but it has the capacity. For your your standard home amuse you really don't need that much data unless you would like implantable and -- Guy you'd probably be easier to memorize -- good job. But what you really all you're really doing is you want a unique identity."
" Well let's take a moment now for short message from the united states air force."
" Oh -- like -- nicest airport on the other commandos boarded the launch of course want to. You know about one of the part of the space program and a dozen airports is an exciting place. You just that we'll we'll realized -- air force base prevents these."
" Equivalent to NASA's site is built in most cases -- the shuttle launches about once a month. And I've got real losses. Here in the next thirty days so if you want to be in the space program here we're very with the."
" are you ready tiger attack what -- what's the software -- so this is actually OEM program that comes with that with the kids. It's. I had it modified this at all rights so edgy as you bring listen closely. What you're gonna see is we will slowly pop up and -- you read that identification number. And what she can't really see in TV land is actually saying. -- at an efficient is 41627. 869. And every time you -- Palin bring it back it'll pop up. So -- actually reading this take. This is something in my grandmother could have done. -- Everything in here this -- Now this doesn't act. Activate anything but this is the off the shelf software that comes with this thing -- just program that would read -- idea and basically -- the next pieces for you of these you would then have to modify this if you want this to open up here you know front door. And you have to modify it -- it you have -- front door mechanism attached to this board which would then open your current. -- so. You can take this program it's totally off the shelf and modify it with something called relay which is basically it's electronic gate that uses the -- current through the stumbled final battery. To close an electronic gate and then a low something like 110 volt AC current. Country that relay and the especially this this could be like the -- body. Part of our securities -- off the shelf. Two dollar -- is I'd buy mine from -- I'd literally Biden and possible hundred as the use them personally ridiculous different things that just remote control if you -- a really it's a remote controls which dates yet it's I would color blood throughout controllers wired remote control so all it does it is that DC current comes through it closes and magnetic -- okay and -- magnetic -- does is that is the contacts which which then allows. The AC to float through in eight what's called normally open circuit because normally open okay opening night. Closing meaning yeah correct no new -- coming -- and then when you put the DC current through it closes that. Switch turning it time you can also have normally closed relays which basically means that it's always alone in the current through. Until the magnetics which activates and it opens and it turned something off cool. Now if you're really getting an RFID. On on -- any really wanted to search start tweaking stuff then you really want to go to -- which specializes. In our -- products and again trust and has so much resources on line. Product like this question eighty bucks and you can hook this product up into. A basic stance board no problem you have to start understanding serial level control because here is our standard nine cancer network. Okay so you're actually using this world guy. I ain't. Why we'll the world go to USB I still don't understand that should be USB port not a serial port but it is what it is you'll probably be using your serial port adapter. And yes and for for those Anderson's behaviors you see here we're adapters. I have one accurate with me literally everywhere I go because you always -- it I'm actually talking to that it does stamp. Board in upcoming US needs but. You -- use -- controller there there fifteen bucks for that. Okay so the parent hacks board will read -- you know for one the right to tags. Hillary's problem is you had the UP SX dot com via -- because it also. Rights and tax rates of the trust and board. Rights to tags as well as -- tags on this is much higher frequency range -- thirteen point 56 makers frequency range heels of my ports or read you know both the is that lower ranges as well -- and there again more expensive just like counseling. Just like -- lacks trust and has done a lot of the harbor for so they date column with a program. That you download. Installed on it took me from clicking on the link. To having a working program on my desktop less than five minutes no magic no programming. Is just as the standard installation. And now this -- it's it's it's the demo software. So you can do you know went with this kind of stuff you know you can read a -- like this. So if you put that -- it's just the same time. Com ports and are yeah don't unfortunately I do you still have to work with comp ports is just one of those those horrible thing and so you can actually see now we actually knows that he'd be hacked. Of this tag is after ED DD -- ones are there is 1 port you know necessary programmable. That is -- program but to."
" Instead of taking an easel and fuels one millimeter maybe two millimeters by a media centimeter and implanting it into your scan. You can plan is just about anywhere. But you know. You may prevent subjects what I really need is a Swedish intern. Excellent."
" And what we're going to do is we're going to take what's called."
" A poison -- this is a -- entering so named because it has a secret little gap -- you can buy these at any."
" Specialty store any golf club things like that. On all it is is the basic. Your basic cute little rings on the -- mind wearing a golf club but it has little national secret compartment where you could put poison -- you're going to poison. You're on tour in whomever he might want to pleasant. So we're okay. How hard -- Japan where your producer yeah. So we're gonna take."
" Our little and -- And we're gonna place this little and you'll. Into -- poisoning. And it's ever so nicely very close upper poisoning. And like Nicholas. It looks like an arm -- and so. The point here is is that we can be creative with RR FID tags so now I'm Camilla fuel community created and -- She says that's me every night -- So we now have what looks to be a normal ring but if -- put that up against. Some are RFID reader. Sure didn't. It's actually reading. That RFID -- So you could pull one of these little tanks just about. January -- rang if you happen to be me professional jeweler. You've created permanently embed that it and you know lake Stanley Signet ring or your wedding -- her anything like that. All right go away."
" The Cincinnati -- are subjecting your ass. This -- terms like -- opinions are just nicer to them a lot nicer like Europe but you thing yeah. So get creative -- RFID -- you can always biodiesel and fuels. Put them just about anywhere. You know you can put him in your belt you can put them. In your shoe you can have -- are. Reader completely invisible sitting on you know you're you're welcome and it's not beautiful -- Oh that is -- ultimately let me see. Not concentrating memory and it they come in very flat versions like that. And they come in versions that you can stick on this stuff such as this black one which. Looks like a black dot you can even use this as as like you know that and other -- and so sticky surface on here so we can. Peel back the -- service. When you guild office that you service you know that's one of those things you can stick to your notebook for instance so I did not take this -- but -- notebooks and now. You know because it -- or -- my notebook has an RFID tag on it they can be read -- I wants or can hold my notebook you know get Wi-Fi access times -- There's a lot of different things you can do this one of which are gonna show us -- and one of which were gonna do in the workshop we're actually going to show how to keep your. Lying cheating good for nothing unemployed brother in law away from your beer which you work hard -- Revision 3 to -- By installing an RFID controlled clock on your refrigerator."
" It's time now for our Netflix sponsored movie pick of the week enemy of the state. They're called color but that Will Smith who unwittingly. Stumble over amber committed by a broad group had -- eighty I was real estate agents who try to eliminate all the formulas because it out."
" Did you alter cast this Jerry Bruckheimer like because action excitement -- all the other improbable things we typically see in movies. -- enemy of the state in your Netflix queue and my daughter don't forget to check out the other 99999. Titles Netflix has including all the latest CD Blu-ray releases."
" You're bound by any movie or TV show you're looking for with over forty shipping centers almost all the everything happening just one business it -- thing for the shipping. -- Portland -- nine but here's a singular to be got a hook up oriented you can get rich -- signing up that dot dot dot dot Netflix dot com slash. System. So Jersey that's important exact same."
" Lamp that we had in the studio but now we want to put this practical usage let's say for example you have a shift was good for nothing -- about remain. I'm in your college and he always -- annually to stop stealing your beer. It's hard to put locks and things like that on your refrigerator that you're not gonna lose so what's -- RFID controlled lock on -- day is hidden. But still completely locks out the refrigerator from the inside rather in the outside. So all -- it is a very simple modification that in addition to the roughly. Sixty to eighty dollars for the micro controller and the board and in the forty bucks for the antenna. We're gonna add two things we're gonna add. A -- Which is actually going to control. Opening and closing of the lock and we're gonna add a three dollar. And it blocks. On and it opens -- this is like 350 asked. Local hardware store. We're also going to need some angle brackets lecture about three bucks just so that we can mount this properly in the refrigerator. Every refrigerator is gonna be a little bit differently so how I show you this might differ from how you're going to do it at home. With your printer we're also going to need. A couple of cable extensions now if you use serve those before you probably noticed that circles always have. Three wires. I'm going between the -- pins and the actual server. Which you can find it very easily. Our -- extension cables. So you can extend those you know like like this the we're gonna need some of these cables to extend the RFID antenna though. Not a problem. With extending RFID antenna is is that it doesn't have three pins it has. Four pins down here. So we have just like on a server we have. Ground and we have voltage but then we have two different things haven't enabled switch as well as a serial output switch so. We now have four cables if you happen to have it be cable maker home. Which is like a twenty dollar tool you can make your -- Four lime wire extension. And if you don't it's a very very simple modification just used to serve a cable extensions. Instead of one and just put to ends on one and then -- on the other so basically you could have six lines coming out which are just using two from each. So that's how we're gonna do this. And the reason we're gonna do this is so that we can actually put the RFID antenna on the outside of the refrigerator. But the controller board and the actual locking mechanism will be inside their refrigerators the refrigerator will actually be locked. From the insides and nobody can cut the lock off. Theoretically somebody could take the antenna off from the outside but that's not gonna open refrigerator. So our idea -- is is put a little extensions on here. Eric put it right back in the same place we had it before. You will of course like all things want to read the manual if you're buying one of these boards it's. It's is a very simple kind of bored. T use you shouldn't have any problem. Using it if you got you know any kind of common sense whatsoever. So. Really tested again now -- put an extension in turn armored. Now the nice thing about this particular RFID antennas -- red indicator light. And so we can you do is testing answer and Hillary take -- RFID capsule could put and it turns green. If it senses a properly identified are ID. We put -- serve well in -- little server mounting holes. The nice thing about this board is it actually comes with pre fitted on certain amounts for -- like to slot the -- in here. And using the program offers a program and if you want a copy of this program is you know -- system at revision3.com and all the happiness and a copy of the program. And we can actually see or hear."
" Turning as I'm. The RFID activate it and so this your vote isn't going to be connected to our little three dollar locking mechanism."
" And this will open and close our refrigerator. All right so let's interpreter."
" Okay so here we have our -- refrigerator. And we want to secure. So first we have put in the -- before we can actually remote control the last so. I've got our little three dollar. Latch right here and I'm just gonna install this into there for traitor now a nice thing about refrigerators is is is really good hard plastic which means that. You can drill into it with self tapping screws and those self tapping screws will hold very securely have to worry about the -- being ripped out next. Who uninstall are you brackets. On it's going to be. Easier for me to install first. The face bracket. And then put the secondary bracket. On it rather than putting these together first of the reason for that is he's because and be able and in need to get through this. Two drilling holes into the refrigerator on the commodore site. So now before add all the electronics I'm gonna make sure the mechanics work. Part of -- here about a system which does is kinda -- it's not really that. On me is that you have to be both mechanical engineer and electrical engineer. So basically this is the mechanical engineering it's really pathetic mechanical engineering but it is -- mechanical. And we'll deal with electrical computer engineering later so. I put in my little test -- only test release came here so that we're not locking ourselves up to now when Amanda was close -- for greater door. And make sure that -- the door closes completely and be that can open it. It's closed. And it won't open because it is now caught on -- I'm good little."
" Could literally so now what pulling us. I can open it so now. And."
" So I closed this. In testing."
" You can hear it snapped shut refrigerator now -- and it's good good want to try opening I can't open it. On because this to -- isn't there but if I pull our -- don't you release protesting release. Now I can open."
" And again if you play with this in -- get much tighter fits into lots of other things you can use electromagnetic locks. You can use all sorts of other different things I want in this as -- as possible. So basically you know. For under ten bucks we built most mechanical stuff here so now -- you real kicker controller board every test to make sure it raises and lowers the lever. By connecting -- hero. To the actual --"
" Now circles always come in what's called horn and what -- is is just a little thing unit that. Little strip of plastic that connects to the service -- hub and an -- go hug turns it moves just like clocked. So I'm just triple tested to make sure that the RFID place. Can actually sense this is now is strictly question. Of mounting. The -- In here we'll actually eventually mountain this. Like this as far as the my version I'm using a battery for simplicity sake. You would actually want to use a hard line in fact. Being refrigerators are electrical appliances you could probably go in from the back always be careful when working with 110. And put an eight permanent power supply to this and then just from the weren't power cable rooms some with a better serve growing installed we want to triple checked to make sure. That the RFID reader is still reading everything properly and that the server will actually open. The the latch and the mechanism all operate here on and also RFID is not a contact technology you don't need to actually touch to do it. On it will be interrupted by -- metal things such as the outsider refrigerator door so unfortunately we can't install. The RFID reader insider for -- can have to go outside and refrigerator. We really don't want dangling cords going up and around so worried due later grant drill a small hole through the door we're gonna run our wires out. I'm on the other side of the door and are insulated because it is the refrigerator and so we do want to keep things insulated which is just released lot of hot glue or something like Batman hot glue when. Keep insulated and okay so I have run the wires outside and refrigerator and find the RFID receiver back and now I'm -- on my -- the capsules. To place it against it. We can see -- screen. And if you can hear that I can actually hear the -- going in the background. So now I know that everything works everything's up and running so announced its question permanently moaning and lets the -- scary scary cast which used to say we're actually gonna now. Close the door and it should lock and we're going to try to open it only -- this. Okay now. Our refrigerator happens to be stainless steel and what that means is that it conducts electricity which sounds obvious except that if you look at your little RFID. Receiver those knows all sorts of contacts sticking out if you're not careful. And you just. Put the RFID antenna. Against the stainless steel refrigerator. It's very easy to shorted out blow it up -- the forty bucks for years here. So I'm covering electrical tape which just helps to insulate it. You might want to use something a little bit more professional you know like. A little rubber standoffs and things like dot. I'm at this will basically helps to protect it on both sides that I have to worry about shoring up on if you happen to have a wood grain refrigerator you don't need that. So final test before you know carrying out together we've still got our little red indicator light here so and I'm gonna take our our fighting taps -- put next to it turned green. And I can opener -- Once I close it again. I can't open their refrigerator so now it's just a question of I'm taping over there are red LEE used to again secure it. And keep it comes from keeping contacts screen. And now we're going to mount a little easier keep out sign it we laser -- seen universally -- on the and we've got a completed refrigerator now. You're lying -- good for nothing unemployed -- can't steal your beer and all you have to do -- walk up with your RFID tag. In this case I'm using a capsule of course you can use an RFID card you can use -- of the art of hiding key files whatever you like you're little secret decoder ring or your poisoning. Come up next to it."
" Should be here this -- yeah. Let's economic think one of our sponsors godaddy.com. If you make an impact on line ability to comment what you need dot com named to -- 199 plus -- fast hosting fast and easy website building and much much more."
" reliable secure and posting -- up a long term contract."
" Go to any hosting plans are bigger and better than ever with 99% of time three point 47 support and no annual commitments I -- myself if you're Canada go to any racially started registering dot."

" At her coach that's like F one when you check out -- an additional 10% off your entire order some restrictions apply -- site -- details your -- the Internet at any time. Support system by supporting them."
" That's it for this episode of system what I want to see for most of you guys is your RFID projects whether it's putting an RFID -- in your grandmother's purse or that she gets stopped every time she looked at a Wal-Mart. Where there -- re encoding RFID tags so that you could walk into your place of work disguised as your best friend or worst enemy. Or you know whatever you're doing uncertainly at Kennedy and million better ideas than just putting an RFID. Crystal inside of a -- I mean there's all sorts of cool things out there and so we want to see you or YouTube videos. I want to see your photos you can post this stuff to use the forums at Revision 3 com slash forums or you can send us an email. System and a revision3.com. Let's get some good."
" like that eight older episodes as always available risen three dot com slash system. And -- fit this episode we hope you enjoyed it Patrick Norton and I -- to see if we can clone that adds that much earlier we're not -- thing where it's from me."
" Wow. Today's system the sponsored by the united states air force that flicks and GoDaddy got cop. -- and -- chipset for pets key cards for the office or newfangled passports RFIDs are everywhere. But exactly how they work in what could use them for home. Today we're gonna bring it all down for him everything from how RFIDs actually work to assembling your own RFID system and incorporating it into something practical. Or something actually kind of in practical like a beer locker for your fridge. One that only a lot when you wait to correct RFID card in front of it denying those less worthy such as your different up only about unemployed brother in law's from act. Accessing the beer inside. Are fighting 11 and building her own -- locker on this episode. System. Well this system I'm Patrick Norton and I and it Calkins. Radio frequency and it."
" Patient is really neat little piece of technology with a whole lot of uses any key current electronic toll systems and -- things. Yes our rhetorical perfect perfect well lets them from Minnesota where we really -- like pronounce her accident. So it's -- perfect -- you know and you know sometimes I need to know her we you know its -- editors -- curator and I actually what it. You got some old whose and he gives me you know who. Now before the email -- pouring in from Minnesota he actually is committed Soviet and -- Minnesota via an exclusive duplicate media being so. Bad streeters tags inventory Wal-Mart -- he's put in the like everything they buy from every company in the planet. Yeah tracking purposes for tracking purposes so there's both the whole lake. Don't steal -- thing but there's also the tracking purposes you know like. What happened to you know two shipments is stolen truck somewhere but it is basically -- you have a guy without you doing physical inventory is check. Track checked in overnight literally just walking by death talent and it was."
" And building building building."
" This is not -- with liquid in the house which blocks the architect response or can interest trees -- you know. I mean they're actually US passports now actually -- have RID tags yes which unfortunately you know every technology can be used for good or evil. Architects."
" AA in -- passports you know can be definitely used for evil because basically. The terrorists probably you're gonna get more usage out of architects because I can walk by you know. Random tourists that are for readers such as this one in my pocket. And find out if you're an American or Canadian -- in the -- has to be -- somebody's gonna Flexilis who -- isn't it pretty decent -- Jon on better readers. You're -- about customizing these devices yet the nice thing about. Our kids now is is they're cheap enough and they're multi so basically like I have in my very quality hear them. I have to activity feed to the workshop. And RFID card you know I never actually take it out of my wallet I actually just -- but against the reader. And it's red and it's just -- dumb little plastic art. Now if you're gonna use something like this at home you don't actually need to buy a second RFID.

I'm placing -- 20000 dollar. I'll order for all sorts -- RFID -- the few companies -- dealt with in all -- research. That is always just absolutely top notch it is in their customer service and the same goes for her elects the other brand of reason these experiments. I'm is both of these guys they have. Awesome web sites with sample code sample products all sorts of things that you have to just byproduct and then. Right all of your own code there's all sorts of stuff is really easy to modify I -- the best part about this is there any special note that these and you'll have."

The real issue isn't that you should be worried about putting in this passive. Little antenna in your skin the real issue that you should do this at home is simply put that you probably don't know how to sterilize yourself the end fuels. Or -- cutting materials properly. Now well gangrene. Treatments have progressed quite a bit since the nineteenth century. I. Really strongly advised against trying to implement one of these in your own skin yeah I mean you have to so yourself that and I mean really people are becoming queasy about structuring."

" are you ready tiger attack what -- what's the software -- so this is actually OEM program that comes with that with the kids. It's. I had it modified this at all rights so edgy as you bring listen closely. What you're gonna see is we will slowly pop up and -- you read that identification number. And what she can't really see in TV land is actually saying. -- at an efficient is 41627. 869. And every time you -- Palin bring it back it'll pop up. So -- actually reading this take. This is something in my grandmother could have done. -- Everything in here this -- Now this doesn't act. Activate anything but this is the off the shelf software that comes with this thing -- just program that would read -- idea and basically -- the next pieces for you of these you would then have to modify this if you want this to open up here you know front door. And you have to modify it -- it you have -- front door mechanism attached to this board which would then open your current. -- so. You can take this program it's totally off the shelf and modify it with something called relay which is basically it's electronic gate that uses the -- current through the stumbled final battery. To close an electronic gate and then a low something like 110 volt AC current. Country that relay and the especially this this could be like the -- body. Part of our securities -- off the shelf. Two dollar -- is I'd buy mine from -- I'd literally Biden and possible hundred as the use them personally ridiculous different things that just remote control if you -- a really it's a remote controls which dates yet it's I would color blood throughout controllers wired remote control so all it does it is that DC current comes through it closes and magnetic -- okay and -- magnetic -- does is that is the contacts which which then allows. The AC to float through in eight what's called normally open circuit because normally open okay opening night. Closing meaning yeah correct no new -- coming -- and then when you put the DC current through it closes that. Switch turning it time you can also have normally closed relays which basically means that it's always alone in the current through. Until the magnetics which activates and it opens and it turned something off cool. Now if you're really getting an RFID. On on -- any really wanted to search start tweaking stuff then you really want to go to -- which specializes. In our -- products and again trust and has so much resources on line. Product like this question eighty bucks and you can hook this product up into. A basic stance board no problem you have to start understanding serial level control because here is our standard nine cancer network. Okay so you're actually using this world guy. I ain't. Why we'll the world go to USB I still don't understand that should be USB port not a serial port but it is what it is you'll probably be using your serial port adapter. And yes and for for those Anderson's behaviors you see here we're adapters. I have one accurate with me literally everywhere I go because you always -- it I'm actually talking to that it does stamp. Board in upcoming US needs but. You -- use -- controller there there fifteen bucks for that. Okay so the parent hacks board will read -- you know for one the right to tags. Hillary's problem is you had the UP SX dot com via -- because it also. Rights and tax rates of the trust and board. Rights to tags as well as -- tags on this is much higher frequency range -- thirteen point 56 makers frequency range heels of my ports or read you know both the is that lower ranges as well -- and there again more expensive just like counseling. Just like -- lacks trust and has done a lot of the harbor for so they date column with a program. That you download. Installed on it took me from clicking on the link. To having a working program on my desktop less than five minutes no magic no programming. Is just as the standard installation. And now this -- it's it's it's the demo software. So you can do you know went with this kind of stuff you know you can read a -- like this. So if you put that -- it's just the same time. Com ports and are yeah don't unfortunately I do you still have to work with comp ports is just one of those those horrible thing and so you can actually see now we actually knows that he'd be hacked. Of this tag is after ED DD -- ones are there is 1 port you know necessary programmable. That is -- program but to."

" Our little and -- And we're gonna place this little and you'll. Into -- poisoning. And it's ever so nicely very close upper poisoning. And like Nicholas. It looks like an arm -- and so. The point here is is that we can be creative with RR FID tags so now I'm Camilla fuel community created and -- She says that's me every night -- So we now have what looks to be a normal ring but if -- put that up against. Some are RFID reader. Sure didn't. It's actually reading. That RFID -- So you could pull one of these little tanks just about. January -- rang if you happen to be me professional jeweler.

Looks like a black dot you can even use this as as like you know that and other -- and so sticky surface on here so we can. Peel back the -- service. When you guild office that you service you know that's one of those things you can stick to your notebook for instance so I did not take this -- but -- notebooks and now. You know because it -- or -- my notebook has an RFID tag on it they can be read -- I wants or can hold my notebook you know get Wi-Fi access times -- There's a lot of different things you can do this one of which are gonna show us -- and one of which were gonna do in the workshop we're actually going to show how to keep your. Lying cheating good for nothing unemployed brother in law away from your beer which you work hard -- Revision 3 to -- By installing an RFID controlled clock on your refrigerator."
" It's time now for our Netflix sponsored movie pick of the week enemy of the state. They're called color but that Will Smith who unwittingly. Stumble over amber committed by a broad group had -- eighty I was real estate agents who try to eliminate all the formulas because it out."

" You're bound by any movie or TV show you're looking for with over forty shipping centers almost all the everything happening just one business it -- thing for the shipping. -- Portland -- nine but here's a singular to be got a hook up oriented you can get rich -- signing up that dot dot dot dot Netflix dot com slash. System. So Jersey that's important exact same."
" Lamp that we had in the studio but now we want to put this practical usage let's say for example you have a shift was good for nothing -- about remain. I'm in your college and he always -- annually to stop stealing your beer. It's hard to put locks and things like that on your refrigerator that you're not gonna lose so what's -- RFID controlled lock on -- day is hidden. But still completely locks out the refrigerator from the inside rather in the outside. So all -- it is a very simple modification that in addition to the roughly. Sixty to eighty dollars for the micro controller and the board and in the forty bucks for the antenna. We're gonna add two things we're gonna add. A -- Which is actually going to control. Opening and closing of the lock and we're gonna add a three dollar. And it blocks. On and it opens -- this is like 350 asked. Local hardware store. We're also going to need some angle brackets lecture about three bucks just so that we can mount this properly in the refrigerator. Every refrigerator is gonna be a little bit differently so how I show you this might differ from how you're going to do it at home. With your printer we're also going to need. A couple of cable extensions now if you use serve those before you probably noticed that circles always have. Three wires. I'm going between the -- pins and the actual server. Which you can find it very easily. Our -- extension cables. So you can extend those you know like like this the we're gonna need some of these cables to extend the RFID antenna though. Not a problem. With extending RFID antenna is is that it doesn't have three pins it has. Four pins down here. So we have just like on a server we have. Ground and we have voltage but then we have two different things haven't enabled switch as well as a serial output switch so. We now have four cables if you happen to have it be cable maker home. Which is like a twenty dollar tool you can make your -- Four lime wire extension. And if you don't it's a very very simple modification just used to serve a cable extensions. Instead of one and just put to ends on one and then -- on the other so basically you could have six lines coming out which are just using two from each. So that's how we're gonna do this. And the reason we're gonna do this is so that we can actually put the RFID antenna on the outside of the refrigerator. But the controller board and the actual locking mechanism will be inside their refrigerators the refrigerator will actually be locked. From the insides and nobody can cut the lock off. Theoretically somebody could take the antenna off from the outside but that's not gonna open refrigerator. So our idea -- is is put a little extensions on here. Eric put it right back in the same place we had it before. You will of course like all things want to read the manual if you're buying one of these boards it's. It's is a very simple kind of bored. T use you shouldn't have any problem. Using it if you got you know any kind of common sense whatsoever. So. Really tested again now -- put an extension in turn armored. Now the nice thing about this particular RFID antennas -- red indicator light. And so we can you do is testing answer and Hillary take -- RFID capsule could put and it turns green. If it senses a properly identified are ID. We put -- serve well in -- little server mounting holes. The nice thing about this board is it actually comes with pre fitted on certain amounts for -- like to slot the -- in here. And using the program offers a program and if you want a copy of this program is you know -- system at revision3.com and all the happiness and a copy of the program. And we can actually see or hear."
" Turning as I'm. The RFID activate it and so this your vote isn't going to be connected to our little three dollar locking mechanism."
" And this will open and close our refrigerator. All right so let's interpreter."
" Okay so here we have our -- refrigerator. And we want to secure. So first we have put in the -- before we can actually remote control the last so. I've got our little three dollar. Latch right here and I'm just gonna install this into there for traitor now a nice thing about refrigerators is is is really good hard plastic which means that. You can drill into it with self tapping screws and those self tapping screws will hold very securely have to worry about the -- being ripped out next. Who uninstall are you brackets. On it's going to be. Easier for me to install first. The face bracket. And then put the secondary bracket. On it rather than putting these together first of the reason for that is he's because and be able and in need to get through this. Two drilling holes into the refrigerator on the commodore site. So now before add all the electronics I'm gonna make sure the mechanics work. Part of -- here about a system which does is kinda -- it's not really that. On me is that you have to be both mechanical engineer and electrical engineer. So basically this is the mechanical engineering it's really pathetic mechanical engineering but it is -- mechanical. And we'll deal with electrical computer engineering later so. I put in my little test -- only test release came here so that we're not locking ourselves up to now when Amanda was close -- for greater door. And make sure that -- the door closes completely and be that can open it. It's closed. And it won't open because it is now caught on -- I'm good little."
" Could literally so now what pulling us. I can open it so now. And."
" So I closed this. In testing."
" You can hear it snapped shut refrigerator now -- and it's good good want to try opening I can't open it. On because this to -- isn't there but if I pull our -- don't you release protesting release. Now I can open."
" And again if you play with this in -- get much tighter fits into lots of other things you can use electromagnetic locks. You can use all sorts of other different things I want in this as -- as possible. So basically you know. For under ten bucks we built most mechanical stuff here so now -- you real kicker controller board every test to make sure it raises and lowers the lever. By connecting -- hero. To the actual --"
" Now circles always come in what's called horn and what -- is is just a little thing unit that. Little strip of plastic that connects to the service -- hub and an -- go hug turns it moves just like clocked. So I'm just triple tested to make sure that the RFID place. Can actually sense this is now is strictly question. Of mounting. The -- In here we'll actually eventually mountain this. Like this as far as the my version I'm using a battery for simplicity sake. You would actually want to use a hard line in fact. Being refrigerators are electrical appliances you could probably go in from the back always be careful when working with 110. And put an eight permanent power supply to this and then just from the weren't power cable rooms some with a better serve growing installed we want to triple checked to make sure. That the RFID reader is still reading everything properly and that the server will actually open. The the latch and the mechanism all operate here on and also RFID is not a contact technology you don't need to actually touch to do it. On it will be interrupted by -- metal things such as the outsider refrigerator door so unfortunately we can't install. The RFID reader insider for -- can have to go outside and refrigerator. We really don't want dangling cords going up and around so worried due later grant drill a small hole through the door we're gonna run our wires out. I'm on the other side of the door and are insulated because it is the refrigerator and so we do want to keep things insulated which is just released lot of hot glue or something like Batman hot glue when. Keep insulated and okay so I have run the wires outside and refrigerator and find the RFID receiver back and now I'm -- on my -- the capsules. To place it against it. We can see -- screen. And if you can hear that I can actually hear the -- going in the background. So now I know that everything works everything's up and running so announced its question permanently moaning and lets the -- scary scary cast which used to say we're actually gonna now. Close the door and it should lock and we're going to try to open it only -- this. Okay now. Our refrigerator happens to be stainless steel and what that means is that it conducts electricity which sounds obvious except that if you look at your little RFID. Receiver those knows all sorts of contacts sticking out if you're not careful. And you just. Put the RFID antenna. Against the stainless steel refrigerator. It's very easy to shorted out blow it up -- the forty bucks for years here. So I'm covering electrical tape which just helps to insulate it. You might want to use something a little bit more professional you know like. A little rubber standoffs and things like dot. I'm at this will basically helps to protect it on both sides that I have to worry about shoring up on if you happen to have a wood grain refrigerator you don't need that. So final test before you know carrying out together we've still got our little red indicator light here so and I'm gonna take our our fighting taps -- put next to it turned green. And I can opener -- Once I close it again. I can't open their refrigerator so now it's just a question of I'm taping over there are red LEE used to again secure it. And keep it comes from keeping contacts screen. And now we're going to mount a little easier keep out sign it we laser -- seen universally -- on the and we've got a completed refrigerator now. You're lying -- good for nothing unemployed -- can't steal your beer and all you have to do -- walk up with your RFID tag. In this case I'm using a capsule of course you can use an RFID card you can use -- of the art of hiding key files whatever you like you're little secret decoder ring or your poisoning. Come up next to it."

Really great episode guys! I think this was the one of the best Systms for a while. Perfect balance of introducing viewers to a technology they may not be be used to working with (RFID), combined with an application of the technology that's perfect for people to get going with, and has low-cost components.
More like this please!

Excellent show. I've been thinking about using some RFID technology, primarily to monitor the individual chickens in my small flock so I know which ones are actually entering the nest boxes and laying (and yes, I'm serious, and no, I'm not smoking reefer). The only problem thus far is the range of the RFID devices. Its hard to explain to a chicken that it needs to walk within a few inches of the reader...kind of like talking to a teenager. So I'm still working on that part.
For a future show, please tell us how to build our own device like yours that will take someone that looks like Patrick and turns them in to someone who looks like Camilla. Now *that* would be "must see TV"!

In reply to davmoo:
You just know that there is going to be a chicken that objects to being scanned like this, and wraps themselves in tinfoil to avoid the scanners. Its hard to explain to a chicken that it needs to walk within a few inches of the reader...kind of like talking to a teenager. So I'm still working on that part.

You should have really talked about the difference between memory tags and computing/crypto tags.
Memory tags where never meant to be used for authentification/authorisation of any kind.
They are often abused as such, which is partly the reason why RFID has such a bad image.
Memory tags (as used on the show) offer NO SECURITY AT ALL!
And even with crypto tags it is not all sunshine. Just think about the Mifare Classic system (widely in use) which was so badly designed that it now offers effectively no security at all after hackers made the effort to try to hack it.
But a nice project, you have here. I like it. Beer fridges need no security.
But you where also talking about home door locking systems, where your system would be plainly crazy and would lower your security to a point of almost non existence. (As far as someone still needs to want to go in your house and have a simple RFID reader to clone your id)
