Ordered the Board from JLC which is some Chinese company. It's crazy how cheap this place is! Kept the board to 2 layers for ease of fabrication and OshPark was gonna charge me $50 ($5/sq in x 10 sq in), but JLC charged me $13 including tax, fees, shipping, and $2 extra for black solder mask! Very impressed. Also I got 5 copies from JLC vs 3 copies from OshPark.
I populated the boost converter and magic smoke stayed in the chips with a steady 5v on the output. I left the jumper off the board for now, I can jack in 5v into the rest of the board separately and see if that works by itself before having power and logic portions mess each other up.
I powered the logic portion and first checked the Astable multivibrator outputs. Seemed like it was correctly triggering every ~1s but I was surprised to see the time-on was about 239ms. I guess I forgot to check the duty cycle in my calculations of the resistors. Will have to change that back down to like 100ms. I set the Red/Yellow/Green threshold voltages at 5v/3v/1v to be able to not kick off the Monostable timer. Turns out there are some stray currents and noise susceptibility that trigger things here and there so I gotta really dive into what is going on. I also noticed that voltage has a really hard time leaking out of the comparator outputs. I manually turned on the FETs for the lights by touching a 5v to the comparator output side and they stay on for a few seconds before turning off. Not sure what to make of that yet.
