From: belvilad@dunx1.ocs.drexel.edu (A. Belville) Subject: Circuit List (locations) Organization: Drexel University, Philadelphia Lines: 73 Here is a list I get when I was combing through some microfilm one day here at Drexel while completely board. Most of these circuits are pretty easy to constuct and can be done by a novice. This is basically some stuff that could prove useful to you without having to sit down and either design or buy the stuff (not a good word, but I'm tired right now). Hope you enjoy! If you have any additions send them to me and I'll add them to the list . They don't have to be from this particular magazine, they just have to be interesting!
