LED Lights powered by discarded batteries
 

Surfing today I found this. They are street lamps that are powered by discarded batteries. The batteries don't have enough juice to power any electronic gadgets, but do have enough left in them to power some LEDs.

I'm thinking it wouldn't be too hard to do something similar for a night light. Maybe use a LED flashlight and modify it?

huh, i've got an old car battery sitting around.......... and i could use a light for my shed until i get power run......... and some random LED's (one busted yard light, busted flashlight, and some from the 3rd brake light off the car my wife totaled.)

simply brilliant.. guess how many batteries i threw away recently... lovely.

We call them "Joule thieves." and they are great for finishing off batteries. (or reconditioning rechargeable batteries.)

Thanks for the link ac7ss. I like the idea, and thats simple enough to make.

that is cool ac7ss.
