From the comments on the Weekend Projects Joule Thief video, folks have found that winding the toroid requires some fussing with how many times to wrap it. Flickr-user Mr Toms World managed to make a nice looking Joule Thief! Nice work! – Link

I had most stuff lying around. I wound the wire around the torid six times and it worked first time.
Keep up the good work
