You should look up the original application notes and datasheets from signetic, they must be 35 years old. (<a href="http://www.datasheetarchive.com/" rel="nofollow">Some Datasheets Here</a>). I wonder which of todays circuits will evolve into cult status in 2040. The 555 timer circuit is a classic.

In some ways I guess it acted like a bias resistor in the transistor's base: http://www.interq.or.jp/japan/se-inoue/e_diode.htm Adding a diode to the base of the transistor would of biased the transistor to a suitable operating point as diodes have a foward voltage drop (the actual voltage drop depends on the diode type).

It may be that I didn't need them. In my novice debugging, I have found that throwing diodes at a problem seems to fix it sometimes :) Hey Matt,

I know diodes limit the current flow in one direction, but why did you need them? I don’t get why the diodes fixed the problem.

I'm having a much better time of it now that someone told me not to let the smoke out of my circuits. :) Babbitt – Yeah, thanks.

For you, a guy who regularly builds cool things out of raw materials and salvaged tools, it struck me as odd to read your tortured experiences with electronics. But then, I recall very well the same feeling of frustration as a young electronic hobbyist... the people who did understand could never explain it in a way that I understood. However, it did become the catalyst for me, and I'm sure, others, to pursue it as a career. Maybe because back then in the dark ages, there were no computers and internet to turn to as an alternative. You, however, seem like a natural HW guy. Missed your calling ? Steve, Nice job.
