Joule Thief

A dozen youth and twenty+ "older youth" participated in our March Mid-Month Madness event.

Our warm-up act was kitting 175 Joule Thieves (GT IE students would've been proud of our production line balancing techniques); we then advanced to the building phase. 

Chief kit-builders Mack, W4AX; Jim, W4QO; & Wes, W3WL guided us through the realities of kit construction & malfunction diagnosis. 

In the end, all kit builders successfully created a working Joule Thief.
