Blue Bawls Automatic Light
Ok get your mind out of the gutter. I am talking about the beautiful blue glass bottle that the Bawls soft drink comes in. I tried one the other day and thought the glass bottle could be used for something interesting. At first I was just going to stick an LED into it, but I wanted something a bit more interesting. So I threw together a quick and dirty circuit that uses a photo-cell to turn on a transistor which powers an LED. The parts should cost only 2 or 3 dollars, and are available almost anywhere. (See page 2 for a parts list.)
I am pleased with the final result, a single super bright white LED lights the glass very well and looks better than I thought it would. There is more than enough light to light up a night table or something similar in size. It is currently running from a 9 Volt battery since that was the simplest means I had, however a small plug in transformer would also do the trick.

Many people are asking who sings the song… The song is Weekend Full of Weekends and can be found here: Garage Band . Thanks to Andy McCaskey of Slashdot Review for turning me onto the site.

See how to make it on the next page.
