Intro: Duct Tape Mini Flashlight
In this instructable I will show how to make a duct tape flashlight. I love portable items. The smaller the better. I felt that duct tape would be an excellent platform to create a mini flashlight.
Step 1: Gather Materials/Tools
For this project I used;
Gray Duct Tape
Three batteries L736
White Led - I know little else beyond the color because I scavenged it.
Copper Wire - I used desoldering braid because it is flexible and provides a good contact point
Step 2: Wiring
The aluminum tape was useful for this step because it is conductive. You could use any conductive material for this step. I used the aluminum tape because it was handy. I would suggest you look at the pictures to follow what I did with the wiring. Explaining it is kind of confusing for me. I imagine anyone reading my explanation would be similarly confused.
The pressure switch I made involved raising one end of the copper wire above the contact point so that I would have to press it down to complete the circuit.
Once you are done wiring put another piece of Duct tape over the wiring.
If you do not know much about LEDs follow this link. I did not use a resistor for this project. Know that if like me you do not use a resistor your batteries will drain very quickly.
Step 3: Final Testing/Thoughts
I tested it after finishing and it worked okay. Some changes I might make would be to use foam to hold the pressure switch and a more rigid piece of copper. Also I wonder if using clear tape to cover the entire thing would make a waterproof light. Another idea I had was to add a magnet and I could stick it to things, like screwdrivers.
This was fun project and I am excited about the possibilities.
