Build a Remote Controlled Beer Keg

Monday, May 18th, 2009 – running time 26:30
We update the classic beer keg with motorized wheels and a remote control tap to build the ultimate robotic beer keg.

Although the modern beer keg has been with us since the 1960's the technology surrounding it has advanced much. Sure the materials might be different, and the gas mixture more suited to wide variety of ales, brews and beer, but really it's still a big metal cylinder that's heavy and difficult to control access to. So we figured we put a few 21st century bits of technology on the thing and turn it into a mobile and easily controlled beer dispenser.

" Wow."

" Like Peter butter chocolate like ebony ivory robot and clear that perfect match how to build yourself okay but coming up this episode of systm. Does that that system has brought you by frost brewed Coors Light the world's most refreshing -- Click it or ticket and Squarespace. Well the system are better."

" Norton -- work before it opens today we're gonna build can bot. And what okay but is to wait for you which not only deliver peer to your friends and things like that but to control their access to it. So -- a remote control will file Kate exactly what not just like it take on wheels -- be simple to me. What we want to do is -- and meals that use the operator that controls here ourselves basically it's sort of like a remote control partner is is it K but drive up to a person. Or just be stationary but you when they got their control. Then are the ones that they're fiercely if you have to control you have it before you our department of yours like the partner are. -- these -- where we -- by some parts. Some of these parts. We use their previous episodes of little robot episodes some of these we haven't. So basically what renewed respect our episode. Forty building block episode months. We're gonna expand on everything we learn an episode forty about how to build a robot which is much. Bigger motor because we need theories such that Chinese surplus promoters are -- work toward use American surplus so there's so. For those people have little push easterners and I'm gonna think you can buy her not too much money am I think these ones were twenty bucks. Are surplus -- which would normally do is put these against yours in your meals. And drive that's what I've done is I've mounted lawnmower wheels -- so we not a direct strike system with. And you just mount that kind of a furniture don't know why -- personally might -- well personally first and foremost. Sun is strong enough to hold they take it here or are basically -- who wants and smaller. This -- to canister which is actually pushes -- and the motors and batteries emails. You can find it any big box appliance story to do is smallpox -- for about thirty bucks. And -- and it's already got all this to rank the to be able to areas that you -- of course at home to me and elaborate as a robot. But you can also. -- Patrick."

" So the cool thing about this is the operator okay but is actually going to be controlling. You're dispensing so to prevent anybody from having too much here he's the one or she is one -- control the on off switch for porn here. The key this is solely it's basically electronics now. And what it's following his face when you -- it opens the now when you take away current it closes it out basically usable electromagnetic device. Very similar to what we use in episode 100 with the flame throwers except in this case. We're not going to be using plain words propane butane -- going to be pushing here. Cool. The next thing we're gonna need is a whole department captain what that means it's into -- peace. Which threads on one hand you can screw in yourself online and on the other end it's a bar and what those bars news is they hold the -- is -- holds in. It's very difficult. For that who's to come back out much like these things or something like that and that way. Helps prevent the hoses from flying out everywhere and I haven't seen you can gas fill the room or beer filled room. City gets it and -- that very -- under filter and worse. The next thing or an eight which were the most critical aspects is called in my dramatic and this is actually I think it's capped -- to -- These are fundamentally different from what you use when you just rented keg -- party he replicate from a party -- hand -- hand pump. Pushes a little bit of air and dedicate to my network to retreat house of we have to do it again. I'm Mike from today actually as of now for cats and so that's CO2 gas canisters which put on the one and then pressurized is the case full time so that you have to constantly pumping gas into. We're also gonna need. A couple hose clamps. Which is very simple little device. Mechanical engineers refer to those as. Rotational tools and -- action figures. I call -- host plant. And -- what you do because it looks like -- little screw and is as useful room. The -- here that clamp gets tighter and tighter and tighter. And."

" Finally of course we're gonna need -- most key parts we're gonna need. Let's see if you canister. Which you can buy or rent from someplace click pastor and a small case router okay because well we have a we want. Want to keep the beer consumption. That -- White House as well and supply houses people and places you know yeah. You'll be able ICU -- so. In your in your region -- who buys a canister lately particularly well but binds -- to history yet you. You've probably right that usually put a deposit down on the container or worst case there's -- by the even -- belongs to them any case cholera is much differently yet. And -- Colorado because you can find. Radically varying prices you'll also find the regulators that same place you find this -- canister as you definitely need to regulator. Your typical beer can't doesn't need more than about 6100. PSI and fear -- us PSI. Pounds per square inch on our particular case is and -- sixty PSI. And this loses. He's gonna -- some sepia is yes so basically you don't need a really -- and regulator I keystone response from Patrick told comes on because mostly because much. -- turn off its. I don't know if it. So you only regular basically regulators to make sure. They you're not pushing on the a full pounds per square inch carbon next time it regulates sit down -- in the second -- if you think think."

" It's."

" Take a while to thank one of our sponsors cores like dot com of course like that compromise where you could just look at the opposite for it -- for cold refreshing cold light. The final review helpful tools support your -- get together with your friends over cool. -- the help and assistance alluring voice recorder like port 53 voice alert allows you to send your pal to personalize reminder to hook up a record of life. If you needed justification for an early exit the court -- excuse your reader provides convincing executions are usually -- or uploaded. Check it all out of course like dot com give us a -- systems support us by check it out that website. So this."

" Steal it and he shot. -- welder so we've."

" that type I hate wouldn't that you guessed the status message. That's. That's -- if you don't. How come a welder at home. Most of these rumors actually come with little spinning. Wheels really tiny ones. And the bulletin is not to. Actually -- them yourself what you do there is the action -- that -- guess -- something like this is it pastor residence your real. But than it actually the motor is -- spinning Caster on in directly rather than directly you have these change has been in this case you want something you physically attached. To be on bodies so look -- robust. That plus you had to speak of -- smokers to work with -- And again you know we're trying to do is basically the stuff we have laying around so this is not an absolute -- he's friends motors. In my case I happen to have nine and he's in. In -- I think in my case I happen added it referred for golly so really when we do things on system we -- to campaign who's -- as possible and we're hoping you Hussein uses rather than going out and buying new stuff. Let's recycle the old stuff. We like exactly. So under the Texas of the Cali what's going on over hydraulic department and I don't department -- I'm -- examination. Thread and screw you see he gets the hard stuff I get this stuff. So basically -- on the Hydro excited offense so long as you can go like this."

" You connection with gears and play together all by yourself. Without make wilders. Did we lose -- Wii owners are very real lean --"

" Ideally when you get back from your. Carbon dioxide supply store on you really want to come back to regular pre regulator pre attack. Tax so basically this is the way that I bought it from -- there. And the reasoning that is because basically there are specialists it's -- stuff regulator. Could cause you problems if you attach it poorly. So it doesn't really cost you anything more and have them do it there so it's really good that's my recommendation if you have them attached regulator. My -- currently is closed until. This is full so now -- me show you how that connect all of the tubes in the assemblies such that we can attach it to decay. And half are pressurized beer so obviously -- micro Mac. I'm right here and what micro -- does again is is that connects the beer line. The CO2 wine and in the final output lines we have three attachments 90% of the kegs in America. Use one standardized happen to put about get a 10% use a different -- so make sure that the tap fitting that you're getting is the same as the case. That you are using. Okay so what you have a cap. Now which Canadian union all of all of your plugs in your settings so basically we're just gonna have all of these now one of the things you want to use. Is PT FE red steel tape which comes in white and yellow forms or in using the white kind today. And basically you just rip off a section and rips off quite easily."

" And you wrap this around of the threats and really what this does is this helps to prevent."

" Gas from escaping if the seal is not."

" Tight enough so we're gonna. Thread thread this on here."

" You really always want a really good thing."

" So no women take."

" From Orange -- And this we'll have a nice could fit on C action takes me some forces to -- And then you're going to want to screw on that -- clamped his nice tight. You actually hear it clicking. Once it's it's to a maximum limit so basically with that is."

" That's the worm years skipping out of this -- want to get raped before it pops out but that's about as tight and you're gonna. Never run the other end to. -- micromanage and the actual lines are marked C connection -- has gas in here. And so the bottom and is always that beer -- and the section goes to the -- the guest in line goes your Hutu line. And in the top is actually where the pressure -- quarters out of an arcade for have a line connected here. Which is going to go to -- solenoid up to this Illinois it will always be pressurized. And that pressurization will hold through this Illinois but then once we trip -- will work out of the solemn almost immediately. So now we need is we need our fittings. Which look like this and so this gas creating and you can see comes in two parts. I'm one is threaded one is not. And so we actually slot yen."

" Or -- like about. And now we're just going to spin the funds to our gas line."

" Connection has a pressure it. -- and again we're just to repeat the process."

" Technically."

" So nominee quickly test system and here we have. A secondary. Closed now. Here we have a primary doctor we have a second or -- and India is this is now close you can only say you see the same thing as your gas winds at home is if it's if it's. Perpendicular. To the event that it's closed the decision turn it parallel to the event that's opens a right now this is closed and this is open. So basically we're just -- given a little bit of pressure. With the clothes. On we can actually see now. Are valve has increased. So we can see getting about. Then fifty. PSI maximum. But that's okay so you can see that the computer side and now I'm actually gonna really close. The primary. So now basically do is we have a little bit of air trapped in here and just to make sure working in an open up. This I closed this cache. And if you heard that that was just that little bit of -- from here releasing so now we know we've got a nice. Tight fitting we didn't hear any gas bleeding off in between this. It was all coming out from. From here. So not only got that done we actually want to add the airline again it's the same process of just screwing on. -- And using hose clamp appeared to. Can it get a nice tight trip. So -- here we have our final post so if this were fully operational right now. And this were hooked up to it here Kate will be happening is is that this compression rates in the beer keg. And and -- beer want to achieve your equilibrium so here would be pulling out here in action be spilling out here's we want to do now is connected this. To our solar -- certainly use yet another. On barbed thing and you see here. What I'm doing is I have an adaptor here so depending on what soul anoint you get depends on what kind of fittings -- adapters yet so our solenoid has a very very fine. Thread sitting on Mac -- so basically this is just an adapter. So that we can fit the proper -- fitting in there and you might find you know proper -- more often than not you'll have to buy two fittings. Anjouan concerned join these two things. These Mercury news. PDF UK. So now going to pop it first for improper clamp on. There are fitting in there. Again we're gonna put this nice tight. Action here comes out. And you could if you wanted to. He could actually attached to Solon and all the way over here on the very front end of the beer tap but I want to have this line going out how to get this only much later on because -- buildings for the specialized box. We can just sit on top of that you're okay. So now -- we have -- solenoid. She showed you earlier and so injection mark in and out. You can see that its mark in on one side and an out is on the other side. On depending on your usage you actually have to follow that we will. It's not mandatory case and hours -- Spin this on. I was at the easy jobs mr. Microsoft and whack yourself in the nine. We need to put one last fitting I'm against the back and and this would actually be where we're gonna pour it appeared out so. We here in charge of -- but. This is the part it's actually. Controlled by your remote control and so this is what action speaks. The beer out three wait wait a second -- And now basically ran into quick test to see if anything's coming out of this. Com by adding that the circuit. Okay the first picture. Your kids seal is. Closed when you open it and push it down -- aren't -- okay. And and we're gonna spin this and and nice fitting owner. Now we're gonna. Locket. We take a battery against her so woman. And a little glass right here. So this is really the sub optimal way of doing this. And now I'm just going to tap on batteries. And there we can see some beer fermenter. -- So obviously our system works great com. I'm just testing and yes they should be using all your clips and things like that. -- everything works and so now the only thing to do is connect this up. Two on any speed controller. So that basically we can have some control not only over. Whether or not this is actually but how often and how much it's actually. Along with B controllers -- motors and then that they're not controlled we're. Are right now to connect all of this you want how is our speed controllers and a radio receiver. Because well it's -- and we don't want spilling all over critical electronic cycle this quick and dirty little box using scrap wood around. The shop. And what this does is this actually contains all of our electronics. So if we look."

" You can see here we have are two -- FIB controllers and these are this B controllers are much stronger. Then the of the when we -- last week because this lucky we -- something this strong push. The motors in -- we were pushing it. Down here this little silver thing is a battery elimination of it like -- know what that does is this is a really strong component which low. Let's let's power to -- collection be you know receiving this signals and pouring beer in a -- robot. Off of the 212 volt batteries rather than having separate radio receiver battery which can be very cumbersome and have to charge that battery. And then finally we haven't Haney little speed controller right here and this little speech control is and actually speaking -- It's more of an on off switch that we can control through the radio receiver so this is actually going troll. The -- which then turns to be reporting on and off. And then this is the master switch up here on top with the measures which is. And basically you you mean powers which is who want to be able co. True robot I'm very easily and then I just put a quick -- cover on this so it can close it. And that way if any of -- or anything else the electronics are mostly protected. It's."

" Big moment -- the sponsors of today's show Squarespace. Feared that if more outlook Revision 3 -- it turns tied up. -- the viewers I'm Tyler our intern -- I'm here to talk about Squarespace which is hands down my favorite publishing platform on the Internet. What I liked most about Squarespace is that it's fast and easy to use but it's so easy you can build a site in three simple things. I want you don't modules pages of features you want your site. To if one of the beautiful templates provided by -- all made by professional designers. And believe sit back and relax your website -- set up to just play around add more content and enjoy it. Congratulations you just save a ton of money by not hiring a web design your Internet -- what can. So what are you waiting for keeping track for big right now it's Squarespace dot com and the -- is the -- system that's as quiet PM when you sign up to get 10% off right here. Your membership. --"

" Now we need to do is a some all of this onto our furniture Dolly and make sure that decay. And that carbon dioxide canister don't fall off and to do that -- you sort of the duct tape of the robotics world called 8020. What age twenty is is extruded aluminum and it comes in very varying links it's very easy to assemble. On using the little channel grabs that they have. And so what I'm gonna be doing is basically just putting in force structure amounts here. On on the sides so that if the robot stocks -- over anything nothing goes flying everything is well secured. To the actual robot aren't let's put that together. Okay I finish wiring -- about together and built this fairly sturdy. Holder which -- make sure that the dear K. And the CO2 canister don't fall out on if anything happens to it and we did this whole project in about six to eight hours some -- you could totally do at home. And I mean this great robot for is working on for one full day so."

" Now I'm gonna look up the batteries turned on and see what happens maybe a --"

" All right we're really tight space right now so I can't really go either about around -- conceded the wheels were just kind thinking you're around a problem."

" Alright now just like a regular remote I'm using a spread spectrum remote. On if you're using something this -- you should probably not use a standard having five megahertz remote controlling should use something in the spread spectrum capabilities and using inspector here. So the normal stick is our our forward left -- right controls with this I'm actually using. The gear up -- down switch to control and fearful because that's nice on off switch and have to worry about cycling and how much and cycling and so basically. When I see here -- own what's happening is is that telling the solar going to turn on as those figures would go down and lunacy gear up it turns a solenoid off and that stops your flow. Now all we need is someone to get it -- oh intern."

" It's an intern OK are you ready for tasty beer."

" Hey how about that."

" Cool. Thanks day you're welcome."

" You wanna keep -- system of course you do that quite usually be wearing a seatbelt. -- click it or ticket people -- Revision 3 joined with hundreds of state local law enforcement the highway safety officials across the nation. Why we have got to crack down on -- seat belt use and reduce highway fatalities. Convince you your friends any motorist or anybody a motor car out there to buckle up day or night. -- objectives that the ATF -- pickup truck drivers and passengers especially among young -- like many of you out there in the audience consistently have the lowest belt use police involved motorists. What this means you're more likely to get severely injured or die if there's an accident. And one of the deadliest act of any vehicle crash occurred in the past -- it from the vehicle which pretty much only happens if you don't wear a seatbelt. What does that mean brain damage death -- hand tied to the hospital just bad doctors' favor what you want to system. So buckle up so here here next week."

" There is -- couple new shows coming up on Monday's we want to tell you about like stand -- comic check out Rockwell every month it's around the best and a comedy round. The world -- world every month it into the rant and -- and DJ KGB. Yes -- is want to believe it comes out every other Monday but until the revision3.com. On Monday."

" As always any ideas or comments or suggestions do email us system at revision3.com. Don't forget to forums at revision3.com platform and visitor archives revision3.com slash system. Hope by the lake and -- always -- your wedding ring off before you well or you end up with. Well thanks -- titanium frames a -- thanking him -- what was done to match it'll."

" And it and it -- we'll see you next week. I don't -- This element is the unit retro. Tell -- test if it works. -- the bombing."

" It has me very."

" We did couple minutes look this cool."

" This is new this is -- this is old you can tell look at this is a bar and this has rebar. Up and."

" Yeah. --"

" Wow."

" Like Peter butter chocolate like ebony ivory robot and clear that perfect match how to build yourself okay but coming up this episode of systm. Does that that system has brought you by frost brewed Coors Light the world's most refreshing -- Click it or ticket and Squarespace. Well the system are better."

" Norton -- work before it opens today we're gonna build can bot.

Which look like this and so this gas creating and you can see comes in two parts. I'm one is threaded one is not. And so we actually slot yen."

" Or -- like about. And now we're just going to spin the funds to our gas line."

" Connection has a pressure it. -- and again we're just to repeat the process."

" Technically."

" So nominee quickly test system and here we have. A secondary. Closed now. Here we have a primary doctor we have a second or -- and India is this is now close you can only say you see the same thing as your gas winds at home is if it's if it's. Perpendicular. To the event that it's closed the decision turn it parallel to the event that's opens a right now this is closed and this is open. So basically we're just -- given a little bit of pressure. With the clothes. On we can actually see now. Are valve has increased. So we can see getting about. Then fifty. PSI maximum. But that's okay so you can see that the computer side and now I'm actually gonna really close. The primary. So now basically do is we have a little bit of air trapped in here and just to make sure working in an open up. This I closed this cache. And if you heard that that was just that little bit of -- from here releasing so now we know we've got a nice. Tight fitting we didn't hear any gas bleeding off in between this. It was all coming out from. From here. So not only got that done we actually want to add the airline again it's the same process of just screwing on. -- And using hose clamp appeared to. Can it get a nice tight trip. So -- here we have our final post so if this were fully operational right now. And this were hooked up to it here Kate will be happening is is that this compression rates in the beer keg. And and -- beer want to achieve your equilibrium so here would be pulling out here in action be spilling out here's we want to do now is connected this. To our solar -- certainly use yet another. On barbed thing and you see here. What I'm doing is I have an adaptor here so depending on what soul anoint you get depends on what kind of fittings -- adapters yet so our solenoid has a very very fine. Thread sitting on Mac -- so basically this is just an adapter. So that we can fit the proper -- fitting in there and you might find you know proper -- more often than not you'll have to buy two fittings. Anjouan concerned join these two things. These Mercury news. PDF UK. So now going to pop it first for improper clamp on. There are fitting in there. Again we're gonna put this nice tight. Action here comes out. And you could if you wanted to. He could actually attached to Solon and all the way over here on the very front end of the beer tap but I want to have this line going out how to get this only much later on because -- buildings for the specialized box. We can just sit on top of that you're okay. So now -- we have -- solenoid. She showed you earlier and so injection mark in and out. You can see that its mark in on one side and an out is on the other side. On depending on your usage you actually have to follow that we will. It's not mandatory case and hours -- Spin this on. I was at the easy jobs mr. Microsoft and whack yourself in the nine. We need to put one last fitting I'm against the back and and this would actually be where we're gonna pour it appeared out so. We here in charge of -- but. This is the part it's actually. Controlled by your remote control and so this is what action speaks. The beer out three wait wait a second -- And now basically ran into quick test to see if anything's coming out of this. Com by adding that the circuit. Okay the first picture. Your kids seal is. Closed when you open it and push it down -- aren't -- okay. And and we're gonna spin this and and nice fitting owner. Now we're gonna. Locket. We take a battery against her so woman. And a little glass right here. So this is really the sub optimal way of doing this. And now I'm just going to tap on batteries. And there we can see some beer fermenter. -- So obviously our system works great com. I'm just testing and yes they should be using all your clips and things like that. -- everything works and so now the only thing to do is connect this up. Two on any speed controller. So that basically we can have some control not only over. Whether or not this is actually but how often and how much it's actually. Along with B controllers -- motors and then that they're not controlled we're. Are right now to connect all of this you want how is our speed controllers and a radio receiver. Because well it's -- and we don't want spilling all over critical electronic cycle this quick and dirty little box using scrap wood around. The shop. And what this does is this actually contains all of our electronics. So if we look."

" You can see here we have are two -- FIB controllers and these are this B controllers are much stronger. Then the of the when we -- last week because this lucky we -- something this strong push. The motors in -- we were pushing it. Down here this little silver thing is a battery elimination of it like -- know what that does is this is a really strong component which low. Let's let's power to -- collection be you know receiving this signals and pouring beer in a -- robot. Off of the 212 volt batteries rather than having separate radio receiver battery which can be very cumbersome and have to charge that battery. And then finally we haven't Haney little speed controller right here and this little speech control is and actually speaking -- It's more of an on off switch that we can control through the radio receiver so this is actually going troll. The -- which then turns to be reporting on and off. And then this is the master switch up here on top with the measures which is. And basically you you mean powers which is who want to be able co. True robot I'm very easily and then I just put a quick -- cover on this so it can close it. And that way if any of -- or anything else the electronics are mostly protected. It's."

Episode 104 - Build a Remote Controlled Beer Keg [Discussion]

Beer kegs have been around since the 60's but the technology really hasn't changed all that much. Well figured it's about time. We put one up on motorized wheels and install a remote control tapping giving you full control over where it goes and how much it pours.

Watch / download here.



--------------------------------------------------------------------------------------

Brilliant episode! proper DIY with robotics and RC! and beer! :) I wonder what beer related robot will appear next week...

I think a worthy addition to the RC beer keg would be a wireless camera so the remote barman can see where they're driving the thing and who's put their glass up to the tap for a drink so they can decide wether or not to give them their drink.


Just one question, did you clean out the solenoid after your unique testing method before the intern got her remotely poured beer? :D

I lied, another question, how good are the Spektrum radio setups? I've probably got near a dozen 27mhz controllers here for my vintage collection of Tamiya RC cars but often find they glitch even at short distances. The only thing that's so far prevented me dipping into the 2.4ghz RC controller setups is the price.

Just an FYI, Micromatic is a brand not a thing. The part that taps the keg is called a sankey. I install beer systems and do cleanings on them, Micromatic supplies about half the gear I use for installations. Also keep the keg below 36 degrees or you will be enjoying cup after cup of head.

50 Psi?



[COLOR="Yellow"]Thats not 50 Psi.[/COLOR] Its 50 Kpa or kilopascals. If you look at the gauge it should be read --> 8 Psi. Did you pick up an empty canister by mistake Dave? (I'm telling you units are important!) :D

Other than that I really liked this show. There definitely seems to be a beer and robot theme going on here.

Interesting. Sure would love to learn how to arc weld. I do not drink beer, but I could see some other applications say as for non-alcoholic beverages. I could also see it for a moveable water sprinkler, yard fertilizer, or the like.

Couple huge mistakes I saw...

1) Don't drive around in your car with a regulator attached to your cylinder. It is not a big deal to attach it yourself, just make sure the gasket is inserted, then tighten up. What we do for our CO2 setup is we put everything (including the cylinder) inside of a toolbox with an adjustable wrench, and after a few minutes of assembly, we are flowing beer!

2) In the beginning, it is suggested that you may need 60 to 100psi of CO2 for your keg. This is not accurate at all. (I believe the line was "Our specific keg needs 60 psi"). You would only use 12-16psi for most beers at a reasonable 34-38 DegF keg temperature.

Edit: Okay, so yes, it looks like Guytheninja is correct in Dave just missing the units. But 8 psi is too low, especially for warm beer. Control speed with hose length, not pressure (you should use about 8 to 10 feet of hose, just go with the micromatic stuff when you buy your tapper).

Yes, you would need higher pressures if you had a more elaborate setup (like 100 or more feet of hose), in which case you really should be mixing nitrogen and CO2. The CO2 is only to keep the beer properly carbonated, the fact it helps bring the beer out is an added bonus.

Just a side note for the corporate sponsor (who I am in no way related to), Coors Light is made in two different ways, but the one I bought last weekend should be pressurized at 14psi at 38 DegF.

The easy way to figure out your pressure is to use this calculator...

You can find out more info at the MicroMatic website for mroe information than you would ever want to know.

Adjustable wrench on a flare nut? For shame. I'm sure Patrick has some proper wrenches.

No teflon tap on solinoid or beer tap. Why not? its cheap.

Plus, Dave's rig is missing a key component: refrigerator or ice to keep the keg cold.

Next version should have optical or IR sensors to make sure that there is a valid glass/mug to catch the beer. Don't want to waste it.

Thats good to know. It makes sense that the optimal pressure is somewhere around 12-16psi. I was very confused when he said 50 psi ----- because [COLOR="Red"]Fire Hydrants[/COLOR] operate at 50 psi :eek: :D.

Another good show, I'd still like to see some scratch build electronics.

Actually It would be interesting

although also a total waste to see what happens if you dispense beer @50psi . . .

it might really change the dynamic of the party.

Cool episode. Glad Systm is back to doing cool projects, also glad to see it away from the green screen set - in the workshop looks so much better!
