Still love playing, but between work and my daughter's marital problems, life ain't a lot of fun.
Bought a Camera Axe kit a few weeks ago... Cool stuff. This is a little interface board that uses an Arduino processor. Web site here: http://www.cameraaxe.com/wiki/index.php?title=Main_Page
The premise is that the electronics have a few inputs and outputs. The inputs are things like sound and light. The outputs fire the camera or flashes. You can program a sound sensor to fire the camera when a balloon pops, or program it to to take a picture of lightning using a simple light sensor.
Built the kit last weekend, and it powered up "first try." Hope to have some examples in the upcoming months.
