In this video, I will show you how to build an over-complicated, yet cool way of blinking an incandescent light. It uses a neon lightbulb blinking in a relaxation oscillator to send a pulse to the grid of a
6CB6 vacuum tube. The tube then turns on a relay that activates the lightbulb.
This project was built for the Flashing Light Prize 2017 contest.
