Pleasant Plains, IL
Built a Bally/Stern lamp driver tester and a Solenoid drive tester based on a write up from Leon Borre. I modified the solenoid driver tester to test the flippers - the 43 volts is supplied by 5 - 9 volt batteries, and I used an old computer power supply to provide the five volts. The LED boards are made from stuff I had around, same for the LEDs.
The cables are made from spare connectors and crimp pins, and store in the boxes when not used. Switches were Radio Shack, who did not have enough of the same style, but they work.
Very simple build - only thing I should have done differently is use a better box. These were pretty cheap - the box lid flexes when using the pushbutton.
Next step is to figure out how to test the high voltage circuitry on the solenoid driver boards -once done, then I would have a way to completely test that board.
