well, it half worked :P There was a significant amount of rain on the day, and despite multiple layers of tarps, we ended up with some water on the electronics, which wasn't good. The video shows how it worked while it was working. Even getting it to work for a little was problematic, one of the i2c chips just refused to have a reliable connection. Stay tuned for an in-depth assessment of why things didn't go well, and lessons learned from actually having to set up ~160 channels worth of igniters.
