So I got it running just how I wanted it. Basically, using the info above + 1 12 Volt Relay hooked to the power button the RP1 now boots up power up. It's basically as 12v trigger. Couple of notes:
- Using an external 12v power source, just drilled an 8mm hole for the 12v socket at the back.
- Keeps everything isolated from the Axiom circuits. The only thing that is physically connected is a Relay that is on for 5 sec at boot to back of the power button (see pic)
- Used the existing mounting holes in the case to mount the board
- Sprayed my board with PCB lacquer in the hope it will slow down the humidity eating it out
- If I don't plug in the 12v then nothing changes in how the RP1 operates previously
Here is where to solder the relay contacts:
