The 4th is nigh but assembly is going smoothly. Still need to do some testing, but most of the boards are mounted in place. The terminals on the left were salvaged ones I hoped to use, but after I got started soldering them, I realized it would be nearly impossible to wire them since the wire openings face downwards.

Scraping enamel off of magnet wire has been the least favorite activity in this project.....

Here we can see the "bus" for one of the igniter power sides: just some thick solid core wire bent into a U-shape and partially stripped.
