Joule Thief FlashlightA cool LED flashlight with an ultra long battery life.
Step 2: Sanding, Taping, and Cutting Step 3 of 6
To protect the coil and keep it nice and neat, I wraped some tape around the coil.
If you forgot to cut the nail in the previous step (like me) you can also cut the nail now.
After that was all done, I cut the loop part into 2 wires. Then I sanded the enamel off of the ends of the wires.
Now you should have 2 coils of wire!
Remeber to keep the top 2 ends separate from the bottom 2 ends as well.
