I mentioned that I will be making a new board to drive my matrix display and I have. This here is a DC-DC power supply for the new matrix driver. What makes this interesting is the method I used to turn on the power. I have plans to encase everything (RGB matrix + driver board + power supply board) up once it’s completed. There will be no external switches whatsoever. So, how does one switch on the power without any accessible switch? My answer is to use two regular rolling-ball tilt switches.
