Electric Chair Joule Thief

Step 5 Finishing up

Now for connecting everything together. I used a torsion spring which I attached to the back of the chair and to the helmet to keep some tension on the battery to keep it in place. I'm sure you can come up with some creative alternative, like magnets or something.
Once it is all assembled, insert the positive end of the battery into the helmet, and stand up the negative end on the metal plate, the L.E.D. should light up, if not, check your wiring and especially check to see if any metal parts on your joule thief are touching. If it works, then congratulations, you can now enjoy watching your dead batteries fry!
