" All right so we're back and workshop amber to -- are ministry amplifier together so a lot of people have had a lot of questions about how to such -- a really good time prosecuted dishonor. So if you're gonna search soldering. The first thing you want to do is getting good sauter and you know those -- little RadioShack. Black plastic sorry here's the crap don't -- us what you would usually good dweller Brandon sorry here exporters. You can get -- to plug it directly to the wall or you can get little soldering stations like this actual temperature controls. Thumb either way whether it's plug into the wall or -- or temperature controlled soldering station. They're both very good to come and lots of different wattage is generally get 35 what plug into the wall -- be okay for most of your sorry purposes. What you've got a good soldering iron. Then it's a good thing to practice soccer in this particular project is really good for that so you can buy -- of practice for called -- such as this one. And you'll notice of these sort of type it bores you have copper on one side and did nothing on the other side. That's basically so the components actually go in of the nothing side and then the wires come out of the copper site and that's actually where you saw her which is what we're beginning today. So when a soldering what you wanted you to take all your components anyone -- from the most shallow component the deepest component. So for today's little experiment will be doing is will be taking these jumper pins -- actually part of the the project and really sorry -- jumper -- Since they are so shallow it's really easy for -- fall outs if you put into a larger. Objects here that would have put in the the jumpers it would just fall out so what do we do is. I've pre drawn all the places permanently jumpers on this board so there I don't have to look back at the that paper I can just push it in through my little black Sharkey points. You know -- flap. On the table. Because it's still a shallow object is not going to fall through its going to be almost flush with the board. Winds honoring this is really important -- have four points of contact. Point number one is the board -- what it's a PCB board or whether it's protecting corporate number two. Is your actual object to component that's coming through that's the wire. Number three major soldering iron we put your soldering iron you want it -- kit right after joint right without wires coming up through the whole. -- here hold it there for about three seconds. And it point number four is the solder was -- to bring in from the you from the opposite you're just gonna barely touch it. He just get a little bit of solder on there. You know -- good -- solder point is what I like refer to as were called volcano is because it actually looks like there's a volcano coming up from the board okay. A bad solder joint looks like the deaths are because you haven't hit the boards -- basically then what you have is he big blob of sauter that's just. Stuck to the wire but it's not actually. BT connection for the board. So this is really that it opportunity for you practice your sorry this sport and just go through with Korean. All of your jumpers and so. So sometimes when you do this -- using lots of kids by trying to put this over to lose a lot of the worry about it just pick it back up we do it but. Yes he lost three of their. Always remember when soldering that too little sauter is much better than two bucks -- if you use too little you can always at a little bit if used too much -- it's really hard to get the actress daughter office of the products allow you to do that. Security inexperienced -- this person. He'll take you awhile to figure out how to use those products we can work. So now I've got arming jumpers are iron on you'll see that there's lots of little wires sticking up. So the -- there really bad in the sense that they're going to poke you in the fingers -- to make it difficult work with when your -- other things. So let me use what's called a diagonal cutters. Which is a wire cutters but it comes in it will. The diagonal. And you want to go in and you want to cut off all those guns and watch out your eyes -- me want to use them. Protective I would do it this. When sorry microchips you never actually sauter. A microchip the heat or cynical electricity is very easy to destroy any property -- microchip. So what she used to use what's called socket. And basically what that is is it something that will hold the microchip in place but it. This is what -- sauter on you actually destroy the microchip. And then once this disorder gone and you slide in the microchip into what's called socket or you can also call it -- They also have. Little clarity on this so if you look on this particular one we shall see is is on one side. There's little hole the little notch and that's -- which way is up for. Microchip that's very important pay attention to the microchip is because they're even on the left and the right -- they have the same number of of -- coming up. But there is a topic there is -- bottom so they're not. Polarity Independent which you can just turn around and over just finds it being very careful knowing which way -- goes him. Sometimes those are you find your soldering iron it's -- and has access sauter on it that's left over. It can you really paying knees -- and what that's basically most soldering stations come with sponges. If yours didn't it was fun discovery to respond to make sure you're not touching the tip of the soldering and and actually if you just wipe across a very wet sponge looks that access one has come off then it'll eat up and cute little so repulsed. On this funds which -- there should be all of them. It -- make a solder bridge which is basically. She goes a -- end up getting too close together and actually join. Of them then actually oddly enough a simple reasonably that we usually kind of open. And you mostly music continuity tester after you're done to make sure that they are still not touching. This is what's called a multi meter and if you happen to have one of this big you can get smaller ones generally a good one just measures. That DC voltage AC voltage. Resistance and continuity which is basically is something touching the better ones actually have a little speaker so any attachments together. You can -- Church. The scenario that cut away my solder -- it was an attack. Tested to make sure does not actually. And it's not. So none -- Soldering gun both claim jumpers as well as mind -- socket so the next step is to suffer under resisters. Always pay attention to. The worksheet when you're making a kid who were following directions like this so that you know exactly which -- sorry. And things like that it is. Is very easy to confuse them they all look very similar. There are two ways. Put resisters imports such as this you can place them vertically or horizontally for this. And it's going to be a little bit easier to -- the resisters vertically. But that means is the resisters action cook up a little bit off of the board."

" It's important to remember. When you're making a -- amplifier if you're looking at this exact instruction guide that while it looks Muir left to right it's an -- actually neared. It's very important to follow the -- extremely closely for instance in the second resisters. This year it's on the first row of the up him. Where as obvious flip side it's on the second -- so it looks kind of like their -- but they're not to pay close attention to make sure. They should not actually was sorry resisters under the wrong -- If you -- on making a lot of projects such as this one of the things you want to invest enormous invest this is like a ten dollar investment is set of jumper. Cables and all these jumpers are. Come in different links in the color coded based on the size and things like this if -- people who doesn't follow directions and read the whole thing. And one of the things that the that the mini -- project to him is is that. What resistor five is actually used so shown in the illustration but resistor five is actually one of those things that. If you're having problems with the -- you can put what's called it pulled down resistor in -- positions but -- nationalist what resistor I was supposed to be so you might just. -- Italy filling it with another thing but in fact the directions say is that you're supposed to use a jumper and now since this is so long you wouldn't want to use a short jumper pins and usually these jumper pins for where it says her -- five. Now fanatic problems if there's lot of static and things like that replaces him with -- We're talking about capacitor is for projects like this you have two kinds of capacity have polarized and non polarized. Much like electrical plug your batteries you don't have a positive and to -- have a negative and two batters look passengers. Which are -- sort of kind of not really like batteries. But only in the history energy have some of them have a negative and positive leads some of them do not so some of them are called polarized. And some of them are called non polarized the com and lots of different looks and designs and things like that's. So in the case of this one it is polarizing you can tell that two different ways. First of all. The negative side is usually colored differently sizzle striped on the negative side there's actual negative mark on there. The second way to tell. Is if you actually look at the metallic leaves one of them is shorter. Then the other and so the shorter run which has been cut off is the minus side and the longer run it is the plus side. In the case of the other passengers who were using. This one is considered a non porous -- so polarized -- distinctly matters which we put it in the board. The non polarized pastor can go in another way. It should be noted that the -- it -- or seek to on the right side. Is jumping across -- three holes rather than to licking his lips and his very heart defendant so if if you're just following the visual sides. I'm on the -- Your pencils nearly impossible to do see me -- move it over one and then just wrapped a wire around solution making contact. The last components you're gonna soldering sauter on is the capacity -- C one for both. Be very careful because it's very hard to understand if you just glancing -- because again these look. Non polarized like for the monitor away. And the right one and the left one or inverted in how you put it on the board so if you're just gonna duplicate if you put the left -- done the same with -- for the right woman. Careful players not for the -- to be very careful to make sure you know which side is negative and which is positive. Okay in making mine mini amplifier I'm gonna go a little bit off the charts here. Two of the big differences here is a -- that you can have a potentiometer on. Your amplifier which basically means it's a second volume control. When basically -- you have a volume control on your iPhone or whatever else is using trip -- secondly. You have an Independent vote female plugs for your mini -- so basically. One would be fun to your iPhone and then the other one would be to your headphones. Well this can be confusing as far as which goes to which there and it also means if you have to have a second plug. Always coming in and so when I want to do is on mine I'm actually going to run and may all mini plug out so that the plug is always there to put directly into. The iPhone or whatever. And that way it's obvious which via headphones always goes into them also not going to use a potentiometer I was gonna use the volume control on my iPhone. So you do all of this basically if you happen to have a dead set of headphones the best way to do this is to use. A dead headphone Jack and just cut off had -- aspect of it. The only headphones like finder and here -- Patrick and he would live music is so I'm actually going to use. Rodgers instead. I'm actually going to use. They little mini headphone Jack plug that you can -- an -- run the wires to it but nonetheless we'll still end up having. An actual. Male plug coming out of it was always obvious. Which -- as much. So there are real few holes on internal towards -- So that we can put our component we're basically -- should consult on. Solder it together and knowing sentiment in there. It was treaty we're gonna test and see who works and -- this -- your first electronic predator -- you're gonna notice years you might not notice is that if you just put your board and like this. You might have noticed that now. All of the components on the other side. Are touching each other because this is a metal object so we want to insulate. The -- can. Instances dirt -- project cookies -- things like -- standoffs. -- posters of -- can use regular old -- electrical tape. And -- at the inside of this twice for the electrical tape and that will basically insulated so that we put auto components and they're not shorting each other out."

" So for those of you who have never inserted a microchip into each hip socket before you're gonna notice that the little pins. Are too wide to fit in the socket so what I can do is I attended just. Take it and squeeze just a little to begin the too little is better than too much easier to squeeze enough to go as we do it but it's hard to then back. And it always check the polarity that little did it on one -- and make sure that that did it matches up with the David in the socket. Okay what you got everything -- together and placed in your box it should look something like this you can see the electrical tape in the background to insulate everything. I got my little Italy do you race here to find out if that's on or off but on off switch. My headphone Jack and like I said before I prefer to use a male plug it so that I can plug this right into my iPhone or whatever it is -- and amplifying rather than using two female plugs and so this is one of those things we can do lots of different designs for instance. You have to have the only -- On this or you can put the only deal the front of other different things are lots of different ways of doing -- Also be careful when you're putting together. You -- mindful battery adapters and make sure you have enough lead. So that you're two adapters can fit both batteries in but not so much as you got wires everywhere because you get too much -- unit it's actually going to be hard to close. So now. This is going to be our task we haven't actually done this before so I have no idea if this you working on the department batteries him. Closing up. -- male -- he does go on so we know that there's something coming out there. And the ability to plug this into the headphone Jack my iPhone. -- Poignantly airboats and see what we get. This sounds a lot better then the amplifier in my iPhone. Just my regular old pods and -- use every single day. Probably get through this and it sounds a lot better it's a lot louder it's a lot cleaner unity on that and it. I really don't think that this is more than about 2030 dollars to parts. At the most com. It takes a little bit longer than if she thought it was going to take and mostly at that is because these -- very tiny. Little compartment so if you're building a big old robot you know lots of room to work with it goes faster because there's more -- room. We're as because of the size the more the worry community. This did not go nearly as fast as -- dissipated there is of course would fringe benefit to making an all points ten bucks. -- for months."

" We Mexican moment now for short message from the United states air force."

" O'Donnell Wagner notices air force come via the commander reported plus of course one of you know about one of the part of space program and the Air Force's. Exciting place you just -- we'll -- don't realize -- air force base program is equivalent to massive size scope and most cases mark. The shuttle launches about once a month. And I've got real losses here the next thirty days so you want to be in the -- quarterly reports released this."

" Mr. Hurley didn't back off a I don't think it's gotten so I'm pretty -- it's pretty cheap dirt cheap. Easy to resemble painfully simple yet it came first avenue and if you do not really get it soldering if something outsider ready people had a component. You can spend eight hours on this if you spread it out over few nights but basically if you pay attention instructions. Four hours 93. If you're like super robot simpler cool guy I didn't mean to zero to me like -- 102000. And -- if you leave the room for our half time.

" Never go back to your day. -- never go to. It's -- it's news --"

" He's the party of one people. Yeah we've put the words in the teleprompter --"

" So direction and make some test -- the nice thing about this particular pocket amplify this. Have lots of Patrick's in the studio and have to fan Patrick. Will destroy any pocket if a -- it's.

Protective I would do it this. When sorry microchips you never actually sauter. A microchip the heat or cynical electricity is very easy to destroy any property -- microchip. So what she used to use what's called socket. And basically what that is is it something that will hold the microchip in place but it. This is what -- sauter on you actually destroy the microchip. And then once this disorder gone and you slide in the microchip into what's called socket or you can also call it -- They also have. Little clarity on this so if you look on this particular one we shall see is is on one side. There's little hole the little notch and that's -- which way is up for. Microchip that's very important pay attention to the microchip is because they're even on the left and the right -- they have the same number of of -- coming up. But there is a topic there is -- bottom so they're not. Polarity Independent which you can just turn around and over just finds it being very careful knowing which way -- goes him. Sometimes those are you find your soldering iron it's -- and has access sauter on it that's left over. It can you really paying knees -- and what that's basically most soldering stations come with sponges. If yours didn't it was fun discovery to respond to make sure you're not touching the tip of the soldering and and actually if you just wipe across a very wet sponge looks that access one has come off then it'll eat up and cute little so repulsed. On this funds which -- there should be all of them. It -- make a solder bridge which is basically. She goes a -- end up getting too close together and actually join. Of them then actually oddly enough a simple reasonably that we usually kind of open. And you mostly music continuity tester after you're done to make sure that they are still not touching. This is what's called a multi meter and if you happen to have one of this big you can get smaller ones generally a good one just measures. That DC voltage AC voltage. Resistance and continuity which is basically is something touching the better ones actually have a little speaker so any attachments together. You can -- Church. The scenario that cut away my solder -- it was an attack. Tested to make sure does not actually. And it's not. So none -- Soldering gun both claim jumpers as well as mind -- socket so the next step is to suffer under resisters. Always pay attention to. The worksheet when you're making a kid who were following directions like this so that you know exactly which -- sorry. And things like that it is. Is very easy to confuse them they all look very similar. There are two ways. Put resisters imports such as this you can place them vertically or horizontally for this. And it's going to be a little bit easier to -- the resisters vertically. But that means is the resisters action cook up a little bit off of the board."

" It's important to remember. When you're making a -- amplifier if you're looking at this exact instruction guide that while it looks Muir left to right it's an -- actually neared. It's very important to follow the -- extremely closely for instance in the second resisters. This year it's on the first row of the up him. Where as obvious flip side it's on the second -- so it looks kind of like their -- but they're not to pay close attention to make sure. They should not actually was sorry resisters under the wrong -- If you -- on making a lot of projects such as this one of the things you want to invest enormous invest this is like a ten dollar investment is set of jumper. Cables and all these jumpers are. Come in different links in the color coded based on the size and things like this if -- people who doesn't follow directions and read the whole thing. And one of the things that the that the mini -- project to him is is that. What resistor five is actually used so shown in the illustration but resistor five is actually one of those things that. If you're having problems with the -- you can put what's called it pulled down resistor in -- positions but -- nationalist what resistor I was supposed to be so you might just. -- Italy filling it with another thing but in fact the directions say is that you're supposed to use a jumper and now since this is so long you wouldn't want to use a short jumper pins and usually these jumper pins for where it says her -- five. Now fanatic problems if there's lot of static and things like that replaces him with -- We're talking about capacitor is for projects like this you have two kinds of capacity have polarized and non polarized. Much like electrical plug your batteries you don't have a positive and to -- have a negative and two batters look passengers. Which are -- sort of kind of not really like batteries. But only in the history energy have some of them have a negative and positive leads some of them do not so some of them are called polarized. And some of them are called non polarized the com and lots of different looks and designs and things like that's. So in the case of this one it is polarizing you can tell that two different ways. First of all. The negative side is usually colored differently sizzle striped on the negative side there's actual negative mark on there. The second way to tell. Is if you actually look at the metallic leaves one of them is shorter. Then the other and so the shorter run which has been cut off is the minus side and the longer run it is the plus side. In the case of the other passengers who were using. This one is considered a non porous -- so polarized -- distinctly matters which we put it in the board. The non polarized pastor can go in another way. It should be noted that the -- it -- or seek to on the right side. Is jumping across -- three holes rather than to licking his lips and his very heart defendant so if if you're just following the visual sides. I'm on the -- Your pencils nearly impossible to do see me -- move it over one and then just wrapped a wire around solution making contact. The last components you're gonna soldering sauter on is the capacity -- C one for both. Be very careful because it's very hard to understand if you just glancing -- because again these look. Non polarized like for the monitor away. And the right one and the left one or inverted in how you put it on the board so if you're just gonna duplicate if you put the left -- done the same with -- for the right woman. Careful players not for the -- to be very careful to make sure you know which side is negative and which is positive. Okay in making mine mini amplifier I'm gonna go a little bit off the charts here. Two of the big differences here is a -- that you can have a potentiometer on. Your amplifier which basically means it's a second volume control. When basically -- you have a volume control on your iPhone or whatever else is using trip -- secondly. You have an Independent vote female plugs for your mini -- so basically. One would be fun to your iPhone and then the other one would be to your headphones. Well this can be confusing as far as which goes to which there and it also means if you have to have a second plug. Always coming in and so when I want to do is on mine I'm actually going to run and may all mini plug out so that the plug is always there to put directly into. The iPhone or whatever. And that way it's obvious which via headphones always goes into them also not going to use a potentiometer I was gonna use the volume control on my iPhone. So you do all of this basically if you happen to have a dead set of headphones the best way to do this is to use. A dead headphone Jack and just cut off had -- aspect of it. The only headphones like finder and here -- Patrick and he would live music is so I'm actually going to use. Rodgers instead. I'm actually going to use. They little mini headphone Jack plug that you can -- an -- run the wires to it but nonetheless we'll still end up having. An actual. Male plug coming out of it was always obvious. Which -- as much. So there are real few holes on internal towards -- So that we can put our component we're basically -- should consult on. Solder it together and knowing sentiment in there. It was treaty we're gonna test and see who works and -- this -- your first electronic predator -- you're gonna notice years you might not notice is that if you just put your board and like this. You might have noticed that now. All of the components on the other side. Are touching each other because this is a metal object so we want to insulate. The -- can. Instances dirt -- project cookies -- things like -- standoffs. -- posters of -- can use regular old -- electrical tape. And -- at the inside of this twice for the electrical tape and that will basically insulated so that we put auto components and they're not shorting each other out."

" So for those of you who have never inserted a microchip into each hip socket before you're gonna notice that the little pins. Are too wide to fit in the socket so what I can do is I attended just. Take it and squeeze just a little to begin the too little is better than too much easier to squeeze enough to go as we do it but it's hard to then back. And it always check the polarity that little did it on one -- and make sure that that did it matches up with the David in the socket. Okay what you got everything -- together and placed in your box it should look something like this you can see the electrical tape in the background to insulate everything. I got my little Italy do you race here to find out if that's on or off but on off switch. My headphone Jack and like I said before I prefer to use a male plug it so that I can plug this right into my iPhone or whatever it is -- and amplifying rather than using two female plugs and so this is one of those things we can do lots of different designs for instance. You have to have the only -- On this or you can put the only deal the front of other different things are lots of different ways of doing -- Also be careful when you're putting together. You -- mindful battery adapters and make sure you have enough lead. So that you're two adapters can fit both batteries in but not so much as you got wires everywhere because you get too much -- unit it's actually going to be hard to close. So now. This is going to be our task we haven't actually done this before so I have no idea if this you working on the department batteries him. Closing up. -- male -- he does go on so we know that there's something coming out there. And the ability to plug this into the headphone Jack my iPhone. -- Poignantly airboats and see what we get. This sounds a lot better then the amplifier in my iPhone. Just my regular old pods and -- use every single day. Probably get through this and it sounds a lot better it's a lot louder it's a lot cleaner unity on that and it. I really don't think that this is more than about 2030 dollars to parts. At the most com. It takes a little bit longer than if she thought it was going to take and mostly at that is because these -- very tiny. Little compartment so if you're building a big old robot you know lots of room to work with it goes faster because there's more -- room. We're as because of the size the more the worry community. This did not go nearly as fast as -- dissipated there is of course would fringe benefit to making an all points ten bucks. -- for months."

" We Mexican moment now for short message from the United states air force."

" O'Donnell Wagner notices air force come via the commander reported plus of course one of you know about one of the part of space program and the Air Force's. Exciting place you just -- we'll -- don't realize -- air force base program is equivalent to massive size scope and most cases mark. The shuttle launches about once a month. And I've got real losses here the next thirty days so you want to be in the -- quarterly reports released this."

" Mr. Hurley didn't back off a I don't think it's gotten so I'm pretty -- it's pretty cheap dirt cheap. Easy to resemble painfully simple yet it came first avenue and if you do not really get it soldering if something outsider ready people had a component. You can spend eight hours on this if you spread it out over few nights but basically if you pay attention instructions. Four hours 93. If you're like super robot simpler cool guy I didn't mean to zero to me like -- 102000. And -- if you leave the room for our half time.
