Joule Thief FlashlightA cool LED flashlight with an ultra long battery life.
Step 4: More Tape! Step 5 of 6
Now tape the battery leads to the AA battery with some electrical tape. Make sure that they have a good connection.
Once that is done, I wrapped the whole circuit up with some electrical tape. This made for a nice, small, compact, LED flashlight. If you don't want to wrap your circuit up with tape, you can always be creative and put it inside any other container you have. :)
