Chief Of Staff of the USAF - Heraldic Device
Here you can see the underside of the device. I deisgned everything to run silently, with little ot no heat. Heat was of concern because the motor for the coin is mounted inside the 'can' above the lamp that illuminates the layers of plexiglas built into the unit, and overheating of the small motor was a major concern. I also designed the circuitry to be servicable instantly. Incase of failure of any component, I made sure I could replace any part in only minutes, requiring no soldering and only a screwdriver.
