 How do you make a tidy breadboard? It's chiptips, chiptips, I have no music and I can't sing. You can use regular jumpers like this, they're a fixed length, and then you can just wire point to point. The problem is that when you've got 10, 20, 30, 40 of these jumpers, it just looks like a big jumble mess. It's not very nice to look at. It's not very photogenic. It's not very YouTube-genic. So let's suppose I've got a couple of chips, I'm just picking some random chips here. Okay, there are our chips. And we want to wire from one pin to the other. Well, we know that the holes on a breadboard are 0.1 inches apart. They're made that way simply so that they can fit dip packages which have a pin pitch of 0.1 inches. In addition, the holes on either side of this divide are 0.3 inches apart, and again, they're made that way because that's the way the dips are shaped. And what about the distance between one of these holes and one of these power holes? Well, unfortunately, that's not 0.3 inches. It's actually 7 millimeters, which turns out to be about 0.26 inches, which is pretty unfortunate. On the other hand, these holes are all 0.1 inches apart. So let's go ahead and make a jumper that goes from this corner pin over to this corner pin. Well, how much are we going to need? 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19. So that's 1.9 inches. Now of course, you're going to need a little bit on the ends. So I've cut this wire so that it's 0.3 inches, and it fits quite nicely. If we bend it over, you can see that there is a little bit of metal sticking out, but it'll do for now. So we measured 1.9 inches across. Now we need to add 0.6 inches for either end. So that's 2.5 inches. Now I have a Knip-X brand wire stripper. That's the wire stripper that I absolutely recommend if you're going to use a wire stripper. You can set the depth of the strip using this adjustment over here. So all I have to do, okay, don't you want one of these now? So 2.5 inches are thereabouts. Let's go ahead and cut that. Here are my flush cutters, which makes it very easy to simply cut the wire properly to the proper length. One, two, and you're done. So let's take a look and see if the length is correct, and it is. So now all I have to do is bend the ends and put the wire in. And there we go. There is a nice wire. It's also quite photogenic. So now what happens if, say, we want to go from here down to ground? Well we know that that's 7 millimeters. So I'm just going to measure out 7 millimeters, okay, convert to inches. It's about 0.27 inches, say. Well again, we know that we have to add 0.6, so that's 0.87. So let's go ahead and make that cut. Now obviously you don't want to be measuring that all the time. However, jumpers between ground and minus and VCC and plus are quite frequent, so you're going to want to make a whole bunch of jumpers of this size. So here we go, 0.87, almost 0.875, and I'm going to cut the ends. There's one, and there's two. And there's my crazy little jumper. Is it the right size? Indeed it is. So I bend the ends over, and I put the jumper in, and there we go. Another perfect jumper. Let's talk about jumping the divide, and let's pose, I don't know, we want to connect this far wire up to this far wire over here. So that's 1, 2, 3, 4, and then we go 3, so that's 7, 8, 9, 10, 11. So we need 1.1 inches. Add 0.6, and that's 1.7 inches, and bent, and there we go. There's another wire. Maybe it's not perfectly straight, and the reason it's not perfectly straight is that I did slightly make it slightly bigger. Okay, now let's suppose you want to make a bend in your wire. So for example, let's suppose you're going from this pin right over here across, down, and across to here. Well, when you bend a wire, you're not making an exact 90-degree angle. And if I measure it against the pins, your bend is actually going to go inside. So you need to subtract a little bit. And a rule of thumb would be to subtract half of 0.1 for each bend that you're going to make. So let's count 1, 2, 3, 4, 5, 6, 7, cross the gap, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19. Now we add 6 for the ends, so 19 plus 6 is 25, and we made two bends. So that's 24. So we're going to need a 2.4-inch wire. Bend the ends in, and there's our jumper. So we want to go from here down to here. So I'm going to put the wire in, and then I'm going to make a nice, sharp bend. And then I'm going to make another nice, sharp bend, and there we go. A perfect jumper. So now the question is, what happens if you're having a jumper that goes over another jumper? Well, if I were to put this jumper on, there is enough slack in that jumper to go across one level of jumper. Now if it were two levels or three levels, then things would get a little dicey. But if you measure one of these typical jumper wires, you'll see that it's about half of 0.1. So if you want to go over, say, two levels of jumper, well, just add 0.1 inches to your measurement. Anyway, that's how you create nice, clean, laid-out breadboards. So remember, 0.1 inches per hole, 0.3 inches to cross the divide, and about 0.26, maybe 0.27, to go across one of these power divides. For every bend, subtract half of 0.1. Well, I hope you enjoyed that. Thanks a lot. See ya. It's chiptips, chiptips, I have no music and I can't sing.
