What you'll need:
- Electrical Tape
- CR2032 Lithium Batteries
- Strong little rare earth magnets
- 10 mm diffused LED lights
Basic build of an LED light
First thing is to check that you have the right legs of the light attached to the right side of your battery so that you know you have a connection and that either your battery or light is working like so:
Then, take your magnets, and place them on your battery and LED legs so that it's stays on the battery. Note that can still move around a bit because the magnet is strong, but not super strong like glue. I'd suggest no glue so that you can use the light and magnets again after the battery has died.
Now, cut a piece of electrical tape and wrap it around your throwie:
And there's your LED throwie! A super easy project to do when you're bored, want to suprise your friends at work and throwing it on random metallic objects or attaching it to your keys when it's stuff inside of your bag at night, and just a simple execution of how a circuit works.
