![]() It's really it just comes down from, you know how you design stuff and I designed stuff a lot like building blocks is I'll, I'll take, I'll take the design apart and build it in separate different ways. That means you have a really good chance on a PCB I would agree there. Yeah, yeah, like especially if you like if you build it like garbage on a on a breadboard and it still works. And I was like that's so true because it's true. But I liked one thing that he said he's like, if you can make it work on a breadboard, you can make it sing on a PCB. The guy said like, how can you ever tell if a circuit is going to work unless you breadboard it I know that's a little ridiculous of course, like experience can tell you a lot but I used to see him in the lab a bunch like testing new stuff, but he was also doing high frequency oscillators and stuff that that did require a bit of tuning the tuning in a little bit of voodoo that you could slap some stuff down on a schematic and like we're like well I calculated things that I hope it works but he also did on on breadboard just to like, prove it to himself. One of the first engineers I ever worked under was was really really anal about breadboarding stuff. So like the pennant star, we knew a lot of this stuff would work and the stuff that we didn't know that worked, I actually designed a couple little tiny boards that were just those things, the SAT test if that sub circuit worked, and then I kind of just went up and popped it on to Eagle. And then at the end DH squish them all together. Now, this microcontroller design, make sure that is good. So I'm like, okay, the power system is good. So it's like everything that revolves around the power goes on this board. So like, like, Why did last couple of weeks with like the power system on the on the badge I'm working on, I actually made that its own board. Then the get breakout boards and all the parts I need that's actually prototype it I will section stuff off. But at that point, it's like it takes almost the same amount of time for me to get a surface mount only PCB built. So it's really hard to I guess you can get breakout boards and that kind of stuff. You know, yeah, so how I handle that is I typically I build because a lot of stuff I do is surface mount now. And then if I make any mistakes, just ordered another Rev. There's sort of like a fine line between like, do I breadboard this and test it? Or do I just ordered the PCB. But all I'm getting at is like, I wish I had more time to breadboard the circuits that I do design. And like, this is the best client ever where they will breadboard your circuit for you that they are having you design. The first picture he said, or video is he puts a cassette in and presses play. Like why not, I'm talking like, multiple breadboard for each schematic page and they sent me a picture of like, a four by eight table with a just breadboard all the way down the thing and like straight up tested the entire circuit that work. And then I provided them with the with the schematic and they went and breadboard the entire thing. I have over 20 pages of schematic in dip trace for their one project. They gave me the specs and the whole spiel of their project, which is absolutely enormous. But this, this client has done something that is absolutely amazing. So I know the back end of that, but like the actual head, like the the the main oscillator, the record head, the Erase head, all that kind of stuff. And so I've never designed anything around, like cassette head control or anything like that. Let's just put it this way, we are implementing some modern electronics in a vintage cassette kind of thing. All fixed, you know, a quick quick little tangent, I'm working with a client right now that So, yeah, I all I had to do was just in the schematic, change that one little little net and then reroute the board that will go funny part. Yeah, the one major copper issue which was so I actually figured out what happened I did hook it up, normally closed and said normally opened. ![]() ![]() Oh, I finally finally got my pinball board ordered rev two of the Patar with the with all the Flipped relay logic, right? Yes. We're your hosts Parker, Dolman and Steven Craig. Welcome to the macro fab engineering podcast.
