The instructions were easy enough to follow, given they are in Chinese! We get the two circuits working perfectly. Really impressed with this one, it works like a charm! Didn’t do any range testing or what not, I’m going to do this one again when my little people come to visit.

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!

In this video we attach some alligator clips to a handful of AA battery holders. I was planning to use these for a Learning the Art of Electronics experiment that I didn’t understand, but now that I understand the problem a bit better I don’t want to go short-circuiting five AA batters… that would be a bad idea!

Silly Job Title: Circuit Sorcerer. I am the Circuit Sorcerer!
In this video we make a cable for connecting the TENMA power supply in the booth to a power outlet on the bench. We use 4mm banana plugs for the TENMA connection and output to a female DC barrel jack on the bench. The wire is scrap speaker wire I had hanging on my pegboard, it was plenty long enough. In fact I had to coil up the wire and zip tie it under the bench. Hopefully the coil doesn’t induce any currents!
