Excuse me, I didn't explain that I actually create the spark by touching the cables together and pulling them apart. I do this to test the size of the on-rush spark and the off-rush spark. Its very revealing.
The 4.7µF cap generates a massive on-spike and without it there is a large off-spike. The cap setup will cramp the relays up in open mode for sure. Setup works best with just the RC's described in my earlier post.
The smaller spark/spike with just the RC's will confuse the board and cause irregular switching. Not crazy bad, but it indicates wear and tare which might get worse and ruin stuff along the line. Also a programmer is writing a nice animation software for it and shouldn't be fragile. It must be able to rock.
Everything is x64 the trouble. Taking the caps back out took many many hours. Otherwise it is a pretty cool piece
