 Where in the world is the Great search brought to you by did you key and a to fruit every single week lady to use their power of engineering help you Yes, you find the things that you want and need on did you get calm thinking did you key lady? To what is the great search of the week? Okay, so if you go to the overhead back I was just talking about How I'm trying to debug this board and I'm having some failures with these signals There they display isn't recognizing these synchronization signals is correct And I don't know why and I'm in a I'm in a snit And so I removed one of these resistor packs in order to get directly through that data So I can pipe in known working data and at least then I can remove one pin at a time until like Magically works. I don't know and to do that. I soldered these wires on and I was like, oh, you know I've never covered wire wrap wire, which can be really really handy This is Kynar wire wrap wire. Oh my god. This is so close and This 30 gauge solid solid core wire with the code like it's called Kynar sometimes Coding I use it all the time for debugging and hot wire fixing boards Sometimes it's called blue wire because people tend to use the blue wire for wire wrap hacks Very very common. I definitely recommend if you're doing PCB design to have some of these because You can get into you can see it's quite small pads You know if you're using like eight eight or ten ten mil wools, you could definitely use this wire So let's go to My computer go to did you keep another option? Because I want it because it's like we just have you in wire up into did you key a little boring You can also use Magnetic wire and this is from Elm Chan who like somehow Has written all code that everyone uses for electronics everywhere Really cool person. I hope one day to meet them So they recognize they've made some beautiful designs and these magnet wire and magnet wire is also a very thin wire I'll say one thing that's nice about magnet wire is that the enamel on it you can see it's It the enamel is what makes it non-conductive. It's often used for coils for you know So it needs to be coiled up and then the enamel keeps it from conducting But it's very very thin you can get a much thinner than wire wrap wire And you don't have that cover that might get in the way But on the other hand, there's the risk that if you nick it it will conduct so it's like it's risky It's like more advanced because it's riskier But it allows you to like really complicated boards like this one you see is a mix of SOIC looks like you know DFN and TQFP so pretty cool stuff. So let's go to Actually, let's go to Wikipedia and I'll just talk about wire wrap. So wire wrap wire was originally used for Wire wrapping around these pins that were used to create PCBs And this was how you did point-to-point wiring before printed circuit boards were basically like two bucks a piece. They used to be Virtually impossible for people to get very very expensive And so students would use or even engineers would use wire wrap wire And they would have these posts that they would wrap using a wire wrapping tool. Actually, sorry, this is not I don't know if they have the tool here. Yeah Wire wrapping tool and so this was a wire would snake in and then you would you twist it and it would make this perfect tight Wrap and it would be like a cold weld. It would be a good soldering connection without soldering And you could undo it and you could with colored wires You could trace it around and you could of course make these complicated 3d shapes So wire wrap wire You know, which is why? Had his own category So let's look at what is available. So it's like 99 which doesn't seem like a lot, but it's like There's not a lot of variation in it. So let's look at active And only stocked it in stock So just you just get rid of all the other ones. So the wire gauge 24 gauge seems really thick. I think that's what actually be used for like wire wrapping power connections um for PCB hacking 30 gauges plenty It's more than enough Next up, um, what color? Basically, everyone goes with blue. I'll say that there's one interesting thing. So there's two Jackets available. There's pvdf Like, you know pvc and that's what I use and it's perfectly fine. You could also get Uh tetrafluor which like a tectathlon. I think is what's sometimes called And these are good at etf etfe is going to be more expensive Um significantly like, you know, this is 100 feet and it's like 40 bucks instead of, you know, 10 bucks um This doesn't have as much temperature. It's it's less, uh, it's more resistant to temperature variation And I believe that when you solder, you know, you solder the the tip of the wire the Jacking doesn't pull away because it's more resistant However, having worked with teflon wire, it's a total pain in the ass to to strip with wire strippers So it's like you have to have it like really good quality wire strip But you can't just kind of oh like it's close enough and I'm just yanking It's not if you just you have to like really cut through And yank rather than just sort of pulling the jacking off. So, um You know, if you absolutely need the temperature resistance go for it. Um, and then, you know You could go by price, uh, you know, we have a role you can get Um Jonard has multiple different colors available kind of like these photos red yellow green Honestly, a lot of people do blue, but one thing I thought was interesting Oh, this is you can just get like little little strips. Um, is that there was a version Because I was like looking at this and I was like, what do you mean with dispenser? So, um, if I had to do it first off, there's this cool Like five wire color kit, which I recommend if you're like going to be doing a lot of wiring Uh and repair it's a little bit more. It's like 85 bucks can get a lot But this is definitely cool. So one thing that is really annoying about wire wrap wire is you buy A spool of a couple hundred feet, but you're never going to get to use it because it gets like knotted so quickly because it's It's like you're pulling in and it's It twists around itself and then it comes off and you rewrap it and then when you rewrap it it gets tangled You can get them with dispensers Which I did not know If I was going to start my life over again With all the knowledge I have She's like it's like a meme I would get Wire up wire with the dispenser. So this is what I recommend not Just a spool get it in this casing. You'll actually get to use the whole thing It's just my pick For the great church
