Description

In this video I build a Joule Thief circuit, complete with enclosure, battery holder, etc. - just for fun. I wanted to show complete process - it is a bit improvised, and the video ended up a bit long. Oh well - it is not easy to record a video of even such a simple project - I always want to show everything, and cut out as little as possible. Here I started with 1.5h of footage - LOL

In the circuit I made one more modification - after a while it began to produce a noise again, so experimentally I stuck 100n cap across secondary, and it stopped squeaking. ;) Will see for how long...

Take care!
