Joule Thief Sounds

I am replicating a test I saw on the net where folks listened to their Joule thief circuits using an AM radio. Yes, this is still the same old AA battery as I used in all of my previous tests. Here I test a regular Joule Thief toroid circuit and the Fuji AA battery circuit. for more info, please go to my topic “Joule Thief” on Overunitydotcom.
