The first prototype of a caboose flasher is now done. David wanted his Atlas cabeese to have red flashing EOT’s on both ends, and be able to swap direction of travel by calling it up on a throttle.
NCE LightIts are very inexpensive, but they don’t have a realistic flashing incandescent bulb effect. So I etched some small PC boards to hold a $1 ATTINY85 processor, a few resistors, and the smallest 5.5V supercapacitor I could find.
F0 controls the LightIt’s warm-white LED. F1 changes direction and F2 shuts off the flasher.
Now all I need to do is build a big pile of them. Time an afternoon wearing an Optivisor!
