Okay, we're working on step one for switch number one or SW1 for our DIY 3220 point breadboard project
0:10
I have a switch here. This is a double pole, double throw on off on switch
0:18
What we're going to do is we're going to cut a piece of wire here in a second and we're going to attach it to pen number two of this switch
0:28
I have a printout here for our prototype of the power supply
0:40
You can find this on the website at motbots.com under this 3220 point redboard project
0:51
And right now we're working on switch number one and pin two
0:56
So what I'm going to do, and by the way, the colors of these wires on this schematic aren't going to match the colors we're going to actually be using for this project
1:07
But anyway, we're working on switch number one, and the first thing we're going to do is we're going to cut a piece of red wire, and we're going to want to solder it to pin to
1:18
here's our switch. You can either refer to this side or the other side of the switch. It's not going to matter. I'm just going to refer to this side and I'm going to rotate it here so we can kind of view the pins here on the bottom side of the switch. If I can get the camera to focus here
1:46
and I going to say that this pin right here or this terminal right here is going to be our terminal 2 for this switch So we refer to our little diagram here
2:06
And as I said, for terminal number 2 there. So I'm going to get some wire
2:13
I'm going to take some red wire. And we need about a 12 inch length of it
2:18
It doesn't have to be exact. But about 12 inches will do good, about there
2:26
And I'll cut that off. And next, what we're going to do is we're
2:35
going to take our wire stripper tool. And we're going to cut back one end of the wire
2:42
the sheathing of it, about an eighth of an inch or so
2:46
not too much, just enough to expose the wire. And I'll do a couple of times
2:51
twist here. And now I have my 12-inch length of red wire and one end of the wire stripped back
3:06
And I'm going to grab my helping hands here off to the side
3:13
And I'm going to use this to help me hold everything so I can solder the wire to pin to
3:20
So again, I'm referring to this side of the switch, and I'm saying that this is going to be pin two
3:29
So that's where I want to solder this wire to. So I'll hold the switch here, and I'm going to take my wire
3:42
And what I first want to do is probably tend that end of the wire That way it be easier to attach to the switch And I also tin number two on the switch
4:06
Just need a little bit of solder to tend the end of it. And then I'll ten into the switch
4:18
the way we get a good connection if I can get everything to rotate for me
4:28
kind of want to go up and down with it kind of come in vertically
4:33
I'm standing up so it's kind of hard to see Okay, we have our first wire connected now
5:01
And let me straighten out everything. What we'll do now is we're going to take a piece of heat shrink tubing
5:13
I don't need this whole piece, so I'm going to take a pair of scissors
5:17
I need just enough to cover this terminal in the wire where we just soldered together
5:27
That way we're kind of protecting that whole area from a little bit more
5:33
So I can protect that area from other conductors or anything in the circuit that might
5:41
touch that and we prevent it from shorting out So we slip that on the other end of the wire and I going to slide it all the way down until it goes over the terminal
5:59
Hopefully you can see that. And then I'm going to take my heat gun
6:09
You got to turn it on first. And then I'm going to heat it up, kind of go around with it, all the way around
6:27
Just let it heat up and fit on that wire and on the terminal of the switch
6:35
get good protection here I'm going to move this and
7:01
So that is on. So that's it for step number one
7:11
We have our first red wire on terminal two of the switch
7:17
Let me move this. We'll see that we have our wire on terminal two of the switch, matching to this terminal
7:33
here on the schematic for switch number one. So that's step one for switch number one for the 3220 point breadboard project
