Circuit boards came today. I soldered everything together and they work! I didn’t, however, account for the height of the tip120s, and had to saw off the heat sink in order for them to fit. I’ll need a better solution for version 2.
I mounted that stationary light.
Also got everything working–it will go through the alphabet. Made a few videos. I feel kinda disappointed this time. I hope it’s just my mood. There are still a few wire snags, some angle tweaks I could make, etc.
