I made a little rig of led lights above my keyboard on my desk. Powered by a 9V battery. Made from scrap parts and a few red led's. All told it cost me about $10.00 us. I let it run for a week straight one time and still had battery left. Ive also made the red led flashlights for astronomy use. Similar to the ones that sell for 30 or 40 dollars for a few dollars. |
