Ultra-basic wiring diagram just to see what is connected to what, voltages, and what not...

By 'power distribution board' I may mean 'tangled mess of wires, solder, and electrical tape'... Just saying... LED control board may be of the solderless breadboard type. For now.

I haven't found a suitable solenoid, but I may end up going with a 12V < 1 inch stroke. It's not much, but it will do until I build a wicked-huge one that actually launches the middle bit at twice the speed of sound. Or not.

I am ordering the LEDs as soon as I am done writing this log. Everything else I should have.
