Arduinill

Here, have some PCBWay deja vu. That’s the new version of dac/ino, the one with the op amp connection not drawn by a chimpanzee. And it works. CV outputs come out as they should, 0–10V or ±5V depending on jumper settings. (The latter is actually more like -5.039 to 4.962V, and I think I have […]

My latest PCBs from PCBWay arrived earlier this week. I assembled one today and, well, I almost got the design right. Back in prehistory, on March 11, I wrote: I’m actually breadboarding another controller, also based around an Arduino and a DAC chip, and it’s occurred to me I could probably design a PC board […]

Got To Blinky

Recently, for reasons I might get to here a little later on, I started thinking about drawing circuit schematics and making PC boards. I did some stuff with the EasyEDA site and I might go back to working with that, I don’t know, but I started feeling like I wanted to try out other options. […]
