Intro: 9 Volt Single LED Sensor Light!!! (Contest Video)
See this YouTube Link!!
See my other I'Bles for steps on how to make it!!
Note:a very simple conversion to USB. Just replace the battery cap with the USB port. The negative of the port should be to your left, while inserting. Same circuit works with 5V (USB) or a 6V battery or a 9V battery, as pictured.
