This is actually more of an experiment to see about uploading video. I built this 555 Flashing Circuit a while back. It was a little project to play with bread-boarding. The frequency of the flashing LED is controlled by a potentiometer. In the video, I say I designed it, but I actually just built it. The circuit came from Electronics for Dummies and a schematic is shown to the right.
My daughter got a new digital camera that can shoot short video clips as well. So, now I can upload video to my blog. Pretty cool! Check it out below. By the way, my daughter is helping with the demo.
