[sixerdoodle] sent us this nice firefly project that serves as an intro to charlieplexing. We’ve mentioned charlieplexing before, in our LED Life post and the Breath Controlled LED candles post.

Christmas is coming up pretty quickly. [tinkernut] shows us how to do a quick and dirty music activated Christmas light setup. Simply crack open a pair of old computer speakers and wire the speaker leads to a relay.

Airwick air fresheners come with an amazing feature. They spray air freshener every once in a while no matter what. It is extremely wasteful and obviously a marketing plan to force you to buy more.

[OldGrover] bought a Weiser electronic lock. Only 6 months after installing it, the keypad stopped working. Instead of just accepting this, [OldGrover] built a better button pad for his lock.

[mixadj] needed to run some video cable from one part of his house to another. He was lacking the proper amount of video cable, but had a bunch of cat5 laying around.

Add lights to your graphing calculator. Do it now. [Sil3ntP8nd8] added some, and seems to have done a decent job. They are spread around the back, supplying a nice even light on, well, on whatever is under your calculator.

Reader [Mike] was not too impressed by design in a recent post we did on an LED menorahs. Doing what any self respecting hacker would do, he designed and built a better one then sent it in to us.

Take a tour of the Mutex laboratories, where mutants are made and nothing could possibly ever go wrong. [Steve] directed us to these videos of the Halloween set up he did with his son this year.
