[quote user="rrinker"]  Hmm,  a capacitor, transistor, diode, and a couple of resistors shouldn;t cost near $29......                         --Randy  [/quote] Yes, I see now that the link to which I was referred in the earlier post was for a more comprehensive power supply circuit with LED indicators and included the purchas of a transformer, for which the author suggested $20 to $30.  But that is not the simple CD circuit which would be cheaper, as you suggest. Another question.........I see an indication in one diagram of what the author calls large current surges.....so is the typical tiny gauge wiring [22 or smaller] of an Atlas switch machine (and of the telephone wire I used to connect to them going to be a problem when hitting them with the jolt from a capacity discharge circuit?
