    thanks for sharing your project. I heard you saying about striping copper wire insulation... I took mine from old bulb transformer, as you. It doesn't seems to be insulated but it doesn't seems to conduct current as well. I'm quite confused. How could I remove this kind of insulation? Thanks in advance

    Great for those solar garden light mods...

    what did you improve/do better compared to the other 78 instructables on making a joule thief ?

    Couldn't you have spend that time doing something new or at least something that was not on instructables /not clear.

    Your robot for example is great.
