Any way to embed gfycat animated HTML5 images? They're wicked fast. Anyhoo, the Blinktronicator seems to be working.

I also uploaded the test program onto the second prototype. This is before I remembered to reset the ATtiny45 fuse to 8 MHz.

The latest firmware/hardware has been pushed to the repo, including a 2-LED-wide test chaser and a new PCB design:

Changes: (1) correctly oriented shift registers (no longer mirror image footprints); (2) slot-shaped USB plug structural pads (rather than 2.5mm plated holes); (3) better programming pads (or, at least, easier to access); (4) wavelength silkscreen rather than "color"; (5) full title instead of just "blinktronicator", which I may or may not update.

I ended up flipping a few shift register connections (and as such, the currently published firmware functions won't work perfectly--I'll fix this when I order the new boards); in the process I also de-cluttered the schematic a bit by separating the resistor networks from the LEDs:

Imagine I didn't accidentally disassociate a library that included the resistor network symbols--they'd be on the right side of the above image. I will fix this at some point, but it is late and I need to go to bed.

I also changed the project name to "blinktronicator". I kept forgetting "Rs" or "Os" and got the files confused a few times. Also, "Bg" should really be "Gb"; 527nm really isn't very blue. It's up-to-date on GitHub and here, but I may have missed a few spots (such as the PCB silkscreen).

So yeah. #blinktronicator.
