Tinker Tuesday for August 27, 2024

This thread is for anyone working on personal projects to share their progress, and hold themselves somewhat accountable to a group of peers. We can coordinate weekly standup type meetings if their is interest.

Post your project, your progress from last week, and what you hope to accomplish this week.


Last week's thread was quite a bit less active than the original one, but I think this is an idea worth continuing, so here we are. Though one thing that might be worth discussing is the pacing of the thread. If there's not so much activity, maybe we can go from weekly to monthly, and if anyone want's to give weekly reports, they can do so under their project's top level comment. Let me know what you think!

I've been working a bit on a "Intro To Circuit Design" sorta class, working to the point where high school students can build a small keyboard, starting from a KICAD schematic, deciding parts and constraints, going to the full process of ordering both circuit boards and parts, hot plate soldering, and loading in a basic firmware. Technically the software and main processor selection is based on this project, though I've stripped out most of the mini OLED screens in favor of just having a handful of handful of WS2812s a la this (partly to keep the part count down, partly for costs, and partly because finding a display module available in quantity <1000 from a vendor that will stay around more than a month is a fool's errand).

I've run it once before and it worked okay, but the nature of the keyboard (especially w/ n-key rollover) made it prone to crossing from repetitive enough to drill in concepts well over from into repetitive enough to bore younger students, especially given KICAD's everything. Made some tweaks, we'll see how it works.
