Silly Job Title: Joule Juggler. I am the Joule Juggler!

In this video we assemble the Children’s Science Technology Small Production Diy Telegraph Machine in the Science Experiment Equipment Stem Education Model.

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.
