While exploring some related links from the previous video on analog computers, I ran across this very interesting link on creating fractals using video feedback.

Courtesy of hack-a-day, check out the following video illustrating an analog computer that implements the dynamics of a bouncing ball, not using a microprocessor, but just a circuit involving analog operational amplifiers.

Weeks ago, I found the following website on constructing ham transmitters using class E amplifiers, and today, I tried to find it again. It took me a couple of tries, so I am archiving the link here. If you want to create a fairly beefy AM transmitter, this is the website to go to.
