I've been asked to make a simple circuit design for a physics class. Basically, I'm looking for something like this: http://ourworld.compuserve.com/homepages/Bill_Bowden/page5.htm#eyes.gif I need something with an item list and a guide as to how to connect it... needs a diagram etc. I've been looking for hours and I honestly cant find one. The one in the link is a perfect example but ironically is the same one my friend is doing. I would be incredibly grateful to those who help!
