Introduction: 5 Min USB LED Light
In this Instructable, I made a simple LED light than can be powered from a USB port.
What do you need:
- 1 x LED
- 1 x 100 ohm Resistor
- 1 x USB cable (it does not matter what cable as long as it has a USB plug)
- 1x Ping-Pong Ball
- Hot glue
Step 1: Prepare the Plug
I cut off the plug and stripped the cables.
We need only red and a black cable. If there are 2 more cables, you can cut them off. They are used for the data.
Step 2: Solder the LED and Resistor to the USB Plug
To make sure the LED does not burn out when connected to a USB port, I soldered a 100 ohm resistor.
Step 3: Put It in the Ping-Pong Ball
I bent the LED, so it would take less space, then I glued it to the plug.
I cut a hole in a ping-pong ball and put it in the USB plug.
A drop of glue was applied, so the ball would not fall off.
