GOOD COMPUTER: Boards
last couple of weeks I tried my hand at designing a board for GOOD COMPUTER. had to resist the urge to add features and just stick with what I know. they arrived today, the five I ordered and siz bonuses. exciting!
starting assembly. I ordered parts to fill them this week but totally forgot about chip sockets. so they’re on their way, and meanwhile I’m improvising
someday I’ll have enough room for a permanent setup but for now this is more than serviceable
most components in. out of header sockets, so I’ve gone with pins for now. still not sure about the serial module (J3). probably a header also; I’m wary of directly soldering the module down if the board doesn’t actually work; they’re a little bit spenny to waste
hello world. confirms power, lights, clock generation and programming. soon will load BASIC to confirm memory and serial, and then I can declare the board good and add a serial module directly
and there it is. didn’t work initially, because I forgot that new AVRs come with very conservative clock settings that, among other things, preclude the USART from working right. quick fuse change and off we go
finished board. the serial module is mounted with a tiny piece of double-sided foam tape, and then soldered
this is not product-quality, and I hope to improve it a lot. for now though, it’s a very convenient little thing to work with on my desk. very pleased!
much nicer. back to work! https://twitter.com/robn/status/1481190626729533444
