" episode fifteen assists perhaps the most frightening episode of systm yet because restarting. With a latex gloves a lot is only her first second he had turned right cock content if I actually where where did you what this is that's right that's that's it so this will. And normally that will -- won't burn like burn it'll burn to bomb burned so late doing this -- be bad that the blood actually do this with the -- that's scary yes care scary though -- everywhere and burn stuff but at what are you gonna do you know what -- have basset. This you can't you're gonna concorde actually make the boards we have to do fought to rid of that. And say what we have -- evening and then you talk about prints are reports that talked about -- and they say -- information printed circuit boards got you so why do we have acid and community meetings and it. Unfortunately we're out of baking soda because of a mistake from earlier but that we need after the actually printed circuit board you're probably best to take off that glove and just throw it away okay the -- something. Don't want to mess with it. This is bad stuff this there's some people through cat eat the cat -- your skin eat your phone before below the -- the floorboards or anything like that it's so bad you can't even put this stuff down the drain. The other cheek copper -- you for your copper pipes speaking of copper pipes it's all up and insert its its all about -- circuit boards and print circuit boards are copper. So. You know if you look at one of those. Pretty much they're everywhere they're everywhere there and everything under the sun. In I mean any electronic device odds are it's got to France are important there the printer port of prince who would you decide of the components that right exactly so your clock radio. At least one prints are warning people there at least one. IPhone iPhone I know there's at least four in there and you can open at least two. So why would make programs circuit -- Well if he's I've been playing some of the product for redundant pass like the eighty are anything like that. You've probably been working on a bread board. This is the prototype keyboard you refer to it -- this is what you figure out what he what wires to go where and how to organize stuff you mock up your circuit you mock up your assert actually making sure it. You make your circuit and it's all there but it's not very convenient is not very you know robust or anything like that vehicle link -- and possibly -- it fell apart exactly. But act you've got it working on there you're ready to commit to the design. And that's when the board comes in so aboard his commitment aboard his commitment to its engagement it's better than an engagement -- and expect -- at the theaters now. So what's there this is just a normal single sided copper -- flip it over so the copper side. And this is the site -- into -- printing on. What's the -- that's with the back let us just basically says that the plastic back on it. There's -- fiberglass inserting between all that so it's nice robust easy to work with. Sometimes Nixon had double sided board that's copper on both sides don't have any ports here that. Because fairly practical work will find it on a small scale we gotta be a little more serious with it so you tell me that with a little to work we can turn this. And something like this on a power circuit -- we're doing this primarily for demo they showed was gone. The light -- goes up above my head. So you're basically using acid etched away the copper from the plastic. Correct -- I feel so smart now so the assets is away the copper wedded only -- the culprit not the plastic. Which is an important thing because you've gotta think about all your cools and everything you're gonna be using that make these circuits didn't. You don't want -- you know middle school copper tools and there to pick stuff up or anything like that bully give me PC -- you showed me this before it's absolutely terrified this is terrifying now. -- what area household heavy duty aluminum foil now I want people to know we're doing this for demo. Don't go doing this in home this releases toxic vapors it's very dangerous there's tons of -- paperwork out there. That actually says this is a bad thing. We can't promise you it's very bad. It's gonna take probably about twenty to thirty seconds for that to fire up. But when it fires. It's just gonna go -- it's gonna go quickly. So if I accidentally or. I took you know aluminum cookie sheets so much stuff then there goes America us so don't use acid in aluminum and don't -- right now. Right because if you did that found an aluminum pan the camera does all the after the spill out. It would be horror. It would -- a bad thing. That's really spooky spooky and it's all gone there's nothing left there and then it was a boy and this is basically this week through your hand really quickly all the way to the -- okay. Com now the problem has -- that you won't notice it right -- could -- take a little bit time. About it kind of -- paying little late. Having neutralize him he should you have a minor spill or features you need to keep a lot of baking soda around that's gonna help you neutralize a lot of it. It's not a pure thing but it's good thing happens is safety thing if you give -- bias. Just call the hospital and go there immediately witnesses. Not something to play around with that this is the -- this isn't like you know minor league second degree burns from the growth is major. Trauma to your flash yes this is Thomas here -- this is worsened shark bites I mean this is. Fingers gone. Such bad things to hate care if you're messing with this if you you're under eighteen to your parents in the room because this is bad stuff I protection. Absolutely. I normally wear glasses but normally if I'm really work with that I want to have goggles on over top of these just for protection. I'm very dangerous clubs and the gloves and -- don't care about and clothes don't care about at a world doesn't care about and a work surface in a room far away from anything of any importance. So how can the design that's gonna go on the -- war. There's a lot of different ways but most of -- start with a laser printer and the good ones. And what to basically do initial prints on to either this transfer paper. Which is the special transfer paper. You'll notice that the logos backwards here. This is just like those teacher transfer papers we're -- put it on and then turn right sign hence the very first use of an iron and systems like yes people probably have noticed from our office that I am not not letting married. Apple now -- Vietnam but -- to literally do this is take that. And put it on the board and iron it. Just like you like T shirt and will happen is is that. It'll stick to it children you that are right when you get the whole thing very evenly -- turn your iron onto the highest setting no steam no water. Just get a very hot. -- the plastic from the transfer sticks that the copper and that's what prevents the -- of running away the copper that you want to remain on the PCB. Actually what happens is the corner from your laser printer bully is what sticks to it. And the transfer paper helps get that -- to stick to it. And that's what protects the copper. Quick note on boxes scrapped when those. Never ever scratching those and you've been working with -- taken gloves off scratch you know put -- so I haven't touched yes. By starts screaming in a minute though until now it's that -- and didn't realize it if it. But after you iron it on there it's the stick to it -- think it's broken up. Just go let it cool to room temperature don't know what's hot and cool to room temperature. And then put it underneath and running water. Yet so been running water and that'll actually release all the glue in the paper -- you just slowly peel it off. Don't let it fall under the water slowly peel off if for the has actually killed us off. What's it is go back and fill in all those little potholes that might get left snow this brings up an interesting point some might say he would absolutely positively totally need the official at resistant pad yes. They would say. Add any book would say that but I use sharply in the past and our -- like well which one's better. And so we devise a little test earlier on. We were just curious on what's better the etching hidden or the -- beat. And if you remember earlier I had you us saw a sign your John Hancock doesn't work -- the war on the board. And appear. Is these -- version. And down here is the -- and so it's safe to say that the sharply get a better job of protecting the copper from the accident the official cool guy expensive -- that yes or CB that's resisted. Except he's just pan. Now the reason why it probably -- reason why they didn't like this is this panel that more. This because it actually runs off a little bit easier the shark you have to kind grind gotten a little bit with a -- and opens a sandpaper. To get the residual sharply off you would think the cool guy official patch resist and would be more resistance or war better -- on copper better go figure so you shortages could. Barely make that counts if you notice yeah I would not work and it yet we have to admit is slightly and unfair test and -- took longer than is should it affect your -- very light Markey urged him normal John Hancock pressing matter. So it wasn't heavy marking that you normally have to do these pins. This would be other -- yes basically UV exposure. It's the same concept as a developing a photograph or getting tan or get an attempt. But still have. Is. A clear transparency sheets him. Printed backwards of course. And -- laid it over top of copper board when you buy those boards. The differences it'll come in these black photo backs otherwise they'll be exposed by -- they would be exposed if you open them up. Generally what you'll find inside of them. And you pitch black where you need it pitch black room working on this they they recommend is little light as humanly possible punitive black room great. Now that -- film over this I'm gonna print and others are translators -- pull back but if you kill all you'll see that copper surface underneath. He put the transfer paper on top of bits and and then what you're gonna do is you're going to put a piece of plexiglas the holder -- various moves against it hence the puts us right here correct. But expose for about fifteen minutes. After you expose it for about fifteen minutes slight hit back into the bank. Wait about another fifteen minutes. And then you have to develop it to like a photograph so you have to have developer. In a separate container. And develop it in this case the developer being asked that it's it's isn't on our -- the work with -- your have to work with another African -- that again. After getting exposed lists it for about another fifteen minutes after it's been in the bag that was the developer hard and honest. And it gets it ready to actually go heading going to let acid. Just like we would do -- the normal printed circuit board with the transfer paper transfer papers definitely simpler. Transfer papers settlers if you lot fewer steps than at the edges are little more roughly have to clean them up a little bit things like. That but. That that -- like keys and because most I'm answer to fine. Com -- circuits simple circuit simple circuits and you know do have people amount Apple them look like this is it's gonna -- black that's the -- left overall that's. All you have to do is pull out of perrello pad. Or you know roughly a sandpaper to think that and you just sandpaper it down in the near the exposed copper. So basically you have to copper -- Relate to copy the system -- he hasn't with a toner looks like that and this is basically where the copper has been eaten away. And that's have to clean it up of the problem. Correct now it's ready for drilling and I have special drilled it's just for PCB has -- just small drill bits. That have a very why. -- Just so that doesn't crack the -- or anything like that. It's good way to work to mount components or anything he -- drill after -- the port -- support just ignore everything else so we talked about. You know -- being bad and in what do you do when you you've you've and state your copper is gone you've got a circuit board in massive map. -- get it -- the acid bath to a point where you can use it without losing your fingers are good at this. Well that's -- gets tricky because what you need do is. He -- he make a tank of a Clearwater runoff to the side. And you know actually picked it up with latex gloves preferably if you've got tweezers or any other type of picking up device you can get in there with that my personal favorite plastic forks. Just gonna pick it up with you know. And just drop it into the water rights at all dropping into another going to just keep dropping -- the and the water until it's crystal clear. And then what you'll do is neutralizes -- some baking soda and and then you can go get rid of all of that excess water this is -- A really good time that you -- RT FM recently exploded manual before you this absolutely really comfortable as before you start. So I pick up a budget Connecticut like kit but this is their decent directions and it -- we recommend for learning more there's always -- out there I recommend is kind of going out there and get your core basics you know combine pieces because audience -- have extra stuff and went back. But you really need to start with that could reference the one you threw me earlier when I was asking me questions was making printed circuit boards again. -- it's a good book. Those you know back in ninety -- that's a little bit dated but not much -- how much does this change not much has been it's been a long time since the significance has been done. They might -- making 38 or somethin' got. And this has all the different methods and there -- overdoing it slaps those involved yeah. So it's got all the different ways and there and got some good diagrams and it's good and helpful now if you're trying not to be overly complicated with that need new windows a simple way. There is. -- So rather than doing some cool guy computer program that creates one of these fancy diagrams I can just draw it right on the copper draw right on there give yourself some architect pay huge self restraint ruling distraught out. And you can actually go to the stores and buy sheets of this which is basic I'd seen those you know there -- RadioShack -- different sizes and what have you. And you just really -- with -- look exactly and -- completion onboard we want. In your -- go to for simple project that's an easy for simple project. An innocent software that's my biggest problem. Is that's you know you can do Photoshop you can do it and auto cad but. There's one piece of software this but it free others called eagle cap. I think back because I sense a trip to the so boxes."

" If you're gonna make a program. They hope people to sign. PCB ports okay. Make it work. You guys who really did not do anything to really help people -- look at all the instructions how to read the forums. You guys keep. And limiting people with the way you actually have to build the circuits you make it hard to move traces around -- go back and and it to component did you make it hard for them actually develop components from scratch."

" You require them to premature download every component and not every component out there has been built. I've tried working with the old."

" You displays. LCD displays."

" Under common components and of metal where there so I have to build them for a worse. And it -- this can't really good --"

" When you turned the pins are wider angle to this. -- favorite program. Not my paper for thank you for that if it. But I kind of -- learned there with that and probably going to be the most accessible thing for most people out there right. It's hard. And it has saved yes. So now some of things this on the tools to point out because he knows all this stuff over here -- you know these are different done. You know bowlers and heaters and all that is a real mad scientist thing -- and on this is yes there is bomb however it's expensive relatively easy to it was so much less. That -- this looks like a piece of Tupperware is that these Tupperware."

" So Tupperware good pirates did aluminum -- brass that copper red steel that."

" Right now my personal favorite -- ceramic. -- is so small crock pots and yard sales terrific effort but. There is little more plus a little more firm -- and you don't have to -- lets you -- to the size from the fall longer it's gonna last little bit better so little bit safer anything clean better don't stand as much and more importantly they are eaten by the asses like aluminum cans that's the important -- remember the foil. I head back. Now -- key things to point out he's -- think that they're called is. He basically. They took a lot of that Saddam didn't. They usually have heating element. And if you look at what these key elements here it looks a lot like it came out of that -- yes gets a little bit hotter because ideally when you work with -- these passes. -- between a 10220. Degrees. Now the -- don't have to get it today temperature. Room temperature work room temperature work or work a little bit slower sometimes the lines won't be as the fine. But some the little secret you can do. Just take your bottles put it into a tub of hot water heat up the chemicals the -- chemicals poured out and you're good enough or better yet since you should be working with us. Outside. Go outside indirect sunlight. And let -- sit there. You actually in the mix the -- before you to to do basically had to hand makes the -- decree the battle. You're dropping the PCP and some of -- have to make some of me -- com which kind of brings us to the different types that are out them. That you know you have the ammonium. -- Which is fun. -- you have these sodium -- sulfate. Both of these you have -- they usually come concentrated usually a dried powder -- work. And -- deal like you for parts of ten parts -- follow have a different recommendations for us try to carry them on the plane with you when you're travelling that. But they all require that even developer requires kind of half water things like that. But it's an increase your car thing it's gonna freeze mullah my personal favorite is I like fair chloride. What's the difference to me these are powder this one is liquid. I mean but they all are all classes draw last says different manufacturers and different techniques require different ways but that all. You need to make sure you have a compatible -- with the manufacture of PCB port. Copper copper got together. This is some relationship they even made up or there -- some different technique. Sometimes some of -- they say you don't really find mind you need to use ammonium. And if you're doing you know double sided board Jesus method. I find that fair chloride works for everything across the board. Because one it's a straight mix and you can just port straight in there drop a circuit board and earn college dot. -- can -- it. That hasn't addressed now what happens -- be cautious I'm just gonna use one and intricate ethnic and so. That's while like that that's a good thing if that's fine at the fair chloride. Does two things one it works better lower temperatures form so like when you're at seven year eighty degrees it seems to work better forming an ass is -- on the board. It actually seems to -- smooth lines and other ones kind of chip away the copper faired very evenly seeps through it you can really see exposure."

" One of these you actually have on this board which is saved because of the gloves you actually see where the copper on the surface the -- started out as smooth as we're that a report. Pondering the future and wandered away because even though there even though you have the platter -- in place about this -- with a toner kind of was gets through with -- in the way that."

" Yeah that's -- as it worked and the problem that is is that if your printer has a bad print head or toner drummer -- like that. You've gotta be real careful to make sure that it's all in there. I notice there's some market -- it's like is that -- that are sharply. A little bit of both I've always had success with sharply myself I -- little bit better. The problem is is that it's harder to get rid of the black part later. Because this -- really sticks however I -- we'll take you know real sandpaper. And just erase the very top of the copper and -- done. Another important -- point out he's -- tanks is the butler. It's a fancy feature and if you're doing really really large boards like a motherboard side or motherboard sizing -- above I think five five inches. Then you probably want to have a butler. Now -- looks complicated but all it really is. Is this a series of poses run along the bottom here with holes and it and it bubbles and it bubbles what does that. What that does this is remember you've got ass than there -- way copper. Anything you can use that agitate the actual capacity kit that cop bad cop for the bad -- of the drug taken up. Okay because basically you wear out yesterday while copper through cracks melt that the right or I wrote I think probably a better term for that in case something on line. Hereby chemistry professor from high schools wailing. And it's. The foot of the meniscus. It is now the funny thing is is you know we buy these kids they include you know pump right. Mom you know road and all that stuff. And it's basically a bunch of this tech stuff from him if you go to fifty you know fish -- store get yourself some of that if moves -- it it's the same effect. There's a lot of players online at what they are only -- she takes. Didn't you know one -- to -- Columbine officially here and done."

" What do you do when you have the giant to juggle -- it. But what you do the end of the day you've made your boards and I have sort of a giant black and copper filled half these passes."

" Right. That's where it gets -- Because dole or in your tray so importing Israelis don't go forward and into the sewage the streets or anything like that. You have to neutralize that or disposed of properly. And you can usually find recycling centers with electronics as you can take it to you. However NASA does quite bit so you know like this think here I can do probably -- couple hundred you know. The Dachshund that's. So -- keep this around and safely stored in my garage not in my house and because that's very important that it does see off chemicals. -- all time. Yes it will see all the guests over time it gets too hot to cold anything like that he need to keep it at a reasonable temperature you know can six. Load reversed in the flame that we obviously it'll eat through the car concrete that neighbor it and it it won't explode or it like like that yeah. It won't explode or anything like that but they can't you let off you know. Fumes and overtime if he gets above or below -- to Chelsea that so that's if you want to avoid. And those -- very toxic so keep them away from everything. Home. We've done that. Go to recycling center neutralize that would just as much baking soda pretty much told solid mass and then you can dispose of it. Com. Sometimes it's clearly it is your better option if you act you neutralize that rather than you think. After you neutralizes everything like here a lot of specific -- in the sewers of illustrated the page be that that would be back in it did if you have well water do you want to ask it in your well water and should be neutralized before it gets the water table but hey. You know you're not gonna get all of -- yeah and don't turn us into it whipping boy for the environment protection agency so the best he can do is get a recycling since there are places that take it. Put it back in a bottle and take it to them and find that where that is both for you mix up the giant pot -- yes that's a good thing. So what you over the acid bath you'll end up actually was something that looks like. This right exactly and in the final step it's to Brill had to scrub it off camera."

" It sure left."

" And take a little bit of -- sometimes people these are real fine grit sandpaper hunt and going to town honest. I like to use the -- pad. Just because it doesn't take as much copper away. Which is kind of important they -- have around for a few sandpaper wouldn't you know two point three pointing."

" At at least in -- like that he the higher the number the better you know. You don't want to get to you know to to -- grainy because the more than double the more you take away the harder for it actually in the circuit false positive and a good time you weren't -- be dust -- yes. -- employment NASA's all night so were okay this is not the mountain our main concern. You can add. Yeah sales and allowed him and he gives you an idea. And that's it that's your whole circuit boards start to finish."

" I think you're working with them with what little keep the secret right now bundle and that in our deepest secrets. Five. We got so we've got some good comin' up stuff we're try to get back to return to get more into little project at the where they did a good job with.

And down here is the -- and so it's safe to say that the sharply get a better job of protecting the copper from the accident the official cool guy expensive -- that yes or CB that's resisted. Except he's just pan. Now the reason why it probably -- reason why they didn't like this is this panel that more. This because it actually runs off a little bit easier the shark you have to kind grind gotten a little bit with a -- and opens a sandpaper. To get the residual sharply off you would think the cool guy official patch resist and would be more resistance or war better -- on copper better go figure so you shortages could. Barely make that counts if you notice yeah I would not work and it yet we have to admit is slightly and unfair test and -- took longer than is should it affect your -- very light Markey urged him normal John Hancock pressing matter. So it wasn't heavy marking that you normally have to do these pins. This would be other -- yes basically UV exposure. It's the same concept as a developing a photograph or getting tan or get an attempt. But still have. Is. A clear transparency sheets him. Printed backwards of course. And -- laid it over top of copper board when you buy those boards. The differences it'll come in these black photo backs otherwise they'll be exposed by -- they would be exposed if you open them up. Generally what you'll find inside of them. And you pitch black where you need it pitch black room working on this they they recommend is little light as humanly possible punitive black room great. Now that -- film over this I'm gonna print and others are translators -- pull back but if you kill all you'll see that copper surface underneath. He put the transfer paper on top of bits and and then what you're gonna do is you're going to put a piece of plexiglas the holder -- various moves against it hence the puts us right here correct. But expose for about fifteen minutes. After you expose it for about fifteen minutes slight hit back into the bank. Wait about another fifteen minutes. And then you have to develop it to like a photograph so you have to have developer. In a separate container. And develop it in this case the developer being asked that it's it's isn't on our -- the work with -- your have to work with another African -- that again. After getting exposed lists it for about another fifteen minutes after it's been in the bag that was the developer hard and honest. And it gets it ready to actually go heading going to let acid. Just like we would do -- the normal printed circuit board with the transfer paper transfer papers definitely simpler. Transfer papers settlers if you lot fewer steps than at the edges are little more roughly have to clean them up a little bit things like. That but. That that -- like keys and because most I'm answer to fine. Com -- circuits simple circuit simple circuits and you know do have people amount Apple them look like this is it's gonna -- black that's the -- left overall that's. All you have to do is pull out of perrello pad. Or you know roughly a sandpaper to think that and you just sandpaper it down in the near the exposed copper. So basically you have to copper -- Relate to copy the system -- he hasn't with a toner looks like that and this is basically where the copper has been eaten away. And that's have to clean it up of the problem. Correct now it's ready for drilling and I have special drilled it's just for PCB has -- just small drill bits. That have a very why. -- Just so that doesn't crack the -- or anything like that. It's good way to work to mount components or anything he -- drill after -- the port -- support just ignore everything else so we talked about. You know -- being bad and in what do you do when you you've you've and state your copper is gone you've got a circuit board in massive map. -- get it -- the acid bath to a point where you can use it without losing your fingers are good at this. Well that's -- gets tricky because what you need do is. He -- he make a tank of a Clearwater runoff to the side. And you know actually picked it up with latex gloves preferably if you've got tweezers or any other type of picking up device you can get in there with that my personal favorite plastic forks. Just gonna pick it up with you know. And just drop it into the water rights at all dropping into another going to just keep dropping -- the and the water until it's crystal clear. And then what you'll do is neutralizes -- some baking soda and and then you can go get rid of all of that excess water this is -- A really good time that you -- RT FM recently exploded manual before you this absolutely really comfortable as before you start. So I pick up a budget Connecticut like kit but this is their decent directions and it -- we recommend for learning more there's always -- out there I recommend is kind of going out there and get your core basics you know combine pieces because audience -- have extra stuff and went back. But you really need to start with that could reference the one you threw me earlier when I was asking me questions was making printed circuit boards again. -- it's a good book. Those you know back in ninety -- that's a little bit dated but not much -- how much does this change not much has been it's been a long time since the significance has been done. They might -- making 38 or somethin' got. And this has all the different methods and there -- overdoing it slaps those involved yeah. So it's got all the different ways and there and got some good diagrams and it's good and helpful now if you're trying not to be overly complicated with that need new windows a simple way. There is. -- So rather than doing some cool guy computer program that creates one of these fancy diagrams I can just draw it right on the copper draw right on there give yourself some architect pay huge self restraint ruling distraught out. And you can actually go to the stores and buy sheets of this which is basic I'd seen those you know there -- RadioShack -- different sizes and what have you. And you just really -- with -- look exactly and -- completion onboard we want. In your -- go to for simple project that's an easy for simple project. An innocent software that's my biggest problem. Is that's you know you can do Photoshop you can do it and auto cad but. There's one piece of software this but it free others called eagle cap. I think back because I sense a trip to the so boxes."

" If you're gonna make a program. They hope people to sign. PCB ports okay. Make it work. You guys who really did not do anything to really help people -- look at all the instructions how to read the forums. You guys keep. And limiting people with the way you actually have to build the circuits you make it hard to move traces around -- go back and and it to component did you make it hard for them actually develop components from scratch."

" You require them to premature download every component and not every component out there has been built. I've tried working with the old."

" You displays. LCD displays."

" Under common components and of metal where there so I have to build them for a worse. And it -- this can't really good --"

" When you turned the pins are wider angle to this. -- favorite program. Not my paper for thank you for that if it. But I kind of -- learned there with that and probably going to be the most accessible thing for most people out there right. It's hard. And it has saved yes. So now some of things this on the tools to point out because he knows all this stuff over here -- you know these are different done. You know bowlers and heaters and all that is a real mad scientist thing -- and on this is yes there is bomb however it's expensive relatively easy to it was so much less. That -- this looks like a piece of Tupperware is that these Tupperware."

" So Tupperware good pirates did aluminum -- brass that copper red steel that."

" Right now my personal favorite -- ceramic. -- is so small crock pots and yard sales terrific effort but. There is little more plus a little more firm -- and you don't have to -- lets you -- to the size from the fall longer it's gonna last little bit better so little bit safer anything clean better don't stand as much and more importantly they are eaten by the asses like aluminum cans that's the important -- remember the foil. I head back. Now -- key things to point out he's -- think that they're called is. He basically. They took a lot of that Saddam didn't. They usually have heating element. And if you look at what these key elements here it looks a lot like it came out of that -- yes gets a little bit hotter because ideally when you work with -- these passes. -- between a 10220. Degrees. Now the -- don't have to get it today temperature. Room temperature work room temperature work or work a little bit slower sometimes the lines won't be as the fine. But some the little secret you can do. Just take your bottles put it into a tub of hot water heat up the chemicals the -- chemicals poured out and you're good enough or better yet since you should be working with us. Outside. Go outside indirect sunlight. And let -- sit there. You actually in the mix the -- before you to to do basically had to hand makes the -- decree the battle. You're dropping the PCP and some of -- have to make some of me -- com which kind of brings us to the different types that are out them. That you know you have the ammonium. -- Which is fun. -- you have these sodium -- sulfate. Both of these you have -- they usually come concentrated usually a dried powder -- work. And -- deal like you for parts of ten parts -- follow have a different recommendations for us try to carry them on the plane with you when you're travelling that. But they all require that even developer requires kind of half water things like that. But it's an increase your car thing it's gonna freeze mullah my personal favorite is I like fair chloride. What's the difference to me these are powder this one is liquid. I mean but they all are all classes draw last says different manufacturers and different techniques require different ways but that all. You need to make sure you have a compatible -- with the manufacture of PCB port. Copper copper got together. This is some relationship they even made up or there -- some different technique. Sometimes some of -- they say you don't really find mind you need to use ammonium. And if you're doing you know double sided board Jesus method. I find that fair chloride works for everything across the board. Because one it's a straight mix and you can just port straight in there drop a circuit board and earn college dot. -- can -- it. That hasn't addressed now what happens -- be cautious I'm just gonna use one and intricate ethnic and so. That's while like that that's a good thing if that's fine at the fair chloride. Does two things one it works better lower temperatures form so like when you're at seven year eighty degrees it seems to work better forming an ass is -- on the board. It actually seems to -- smooth lines and other ones kind of chip away the copper faired very evenly seeps through it you can really see exposure."

" One of these you actually have on this board which is saved because of the gloves you actually see where the copper on the surface the -- started out as smooth as we're that a report. Pondering the future and wandered away because even though there even though you have the platter -- in place about this -- with a toner kind of was gets through with -- in the way that."

" Yeah that's -- as it worked and the problem that is is that if your printer has a bad print head or toner drummer -- like that. You've gotta be real careful to make sure that it's all in there. I notice there's some market -- it's like is that -- that are sharply. A little bit of both I've always had success with sharply myself I -- little bit better. The problem is is that it's harder to get rid of the black part later. Because this -- really sticks however I -- we'll take you know real sandpaper. And just erase the very top of the copper and -- done. Another important -- point out he's -- tanks is the butler. It's a fancy feature and if you're doing really really large boards like a motherboard side or motherboard sizing -- above I think five five inches. Then you probably want to have a butler. Now -- looks complicated but all it really is. Is this a series of poses run along the bottom here with holes and it and it bubbles and it bubbles what does that. What that does this is remember you've got ass than there -- way copper. Anything you can use that agitate the actual capacity kit that cop bad cop for the bad -- of the drug taken up. Okay because basically you wear out yesterday while copper through cracks melt that the right or I wrote I think probably a better term for that in case something on line. Hereby chemistry professor from high schools wailing. And it's. The foot of the meniscus. It is now the funny thing is is you know we buy these kids they include you know pump right. Mom you know road and all that stuff. And it's basically a bunch of this tech stuff from him if you go to fifty you know fish -- store get yourself some of that if moves -- it it's the same effect. There's a lot of players online at what they are only -- she takes. Didn't you know one -- to -- Columbine officially here and done."

" What do you do when you have the giant to juggle -- it. But what you do the end of the day you've made your boards and I have sort of a giant black and copper filled half these passes."

" Right. That's where it gets -- Because dole or in your tray so importing Israelis don't go forward and into the sewage the streets or anything like that. You have to neutralize that or disposed of properly. And you can usually find recycling centers with electronics as you can take it to you. However NASA does quite bit so you know like this think here I can do probably -- couple hundred you know. The Dachshund that's. So -- keep this around and safely stored in my garage not in my house and because that's very important that it does see off chemicals. -- all time. Yes it will see all the guests over time it gets too hot to cold anything like that he need to keep it at a reasonable temperature you know can six. Load reversed in the flame that we obviously it'll eat through the car concrete that neighbor it and it it won't explode or it like like that yeah. It won't explode or anything like that but they can't you let off you know. Fumes and overtime if he gets above or below -- to Chelsea that so that's if you want to avoid. And those -- very toxic so keep them away from everything. Home. We've done that. Go to recycling center neutralize that would just as much baking soda pretty much told solid mass and then you can dispose of it. Com. Sometimes it's clearly it is your better option if you act you neutralize that rather than you think. After you neutralizes everything like here a lot of specific -- in the sewers of illustrated the page be that that would be back in it did if you have well water do you want to ask it in your well water and should be neutralized before it gets the water table but hey. You know you're not gonna get all of -- yeah and don't turn us into it whipping boy for the environment protection agency so the best he can do is get a recycling since there are places that take it. Put it back in a bottle and take it to them and find that where that is both for you mix up the giant pot -- yes that's a good thing. So what you over the acid bath you'll end up actually was something that looks like. This right exactly and in the final step it's to Brill had to scrub it off camera."

" It sure left."

" And take a little bit of -- sometimes people these are real fine grit sandpaper hunt and going to town honest. I like to use the -- pad. Just because it doesn't take as much copper away. Which is kind of important they -- have around for a few sandpaper wouldn't you know two point three pointing."

" At at least in -- like that he the higher the number the better you know. You don't want to get to you know to to -- grainy because the more than double the more you take away the harder for it actually in the circuit false positive and a good time you weren't -- be dust -- yes. -- employment NASA's all night so were okay this is not the mountain our main concern. You can add. Yeah sales and allowed him and he gives you an idea. And that's it that's your whole circuit boards start to finish."

" I think you're working with them with what little keep the secret right now bundle and that in our deepest secrets. Five.
