Oh man. Today I recorded a whole Mail Call video for the channel and at the end realized the microphone was off the whole time! Boo. Anyway. I was going to put some notes about my TVS diodes in the show notes, but as there is no longer going to be a show, I’m just making some notes here.
Particularly I ordered 210Pcs One way and 210Pcs Two way. I have stored both types in the same component drawer, by their ratings. The one-way devices have a polarity band and use the ‘A’ suffix on the component code; the two-way devices have no polarity band and use the ‘CA’ suffix.

The fun thing about this project is that it works even though it doesn’t have a power supply. That’s because the LED sucks energy from the ambient light to charge the capacitors!
It took me three goes to make this work. The first go was with 100 nF ceramic caps on veroboard, and that didn’t work. The next go was with 470 µF electrolytic caps on breadboard, and that didn’t work. Finally I had a go with 1 µF polypropylene film caps and that worked!
