This controller is really cool and compact!
It consists of a: 6 channel Key Banger, custom relay board with 10 "normally open" contacts and 2 "normally closed" contacts, and 4 available power sources, 5VDC, 12VDC, 24VDC, and 35VDC!
Here is a little video I posted that cut into my sleep a little last night.
