Hey... where have jeffrey and dave been??? Well the answer to that is busy. To add at least a little content to this miniscule corner of the web, here is one of the small things I have recently made.
This is a "keeper" board that attaches to a pc mount bobbin and holds a schottky bridge and a pair of caps for a choke input filament supply. The chokes are dual bobbin and wound with flat wire for choke input duty and have split windings so one leg goes in the + side of the supply and the other in the ground. The PC mount bobbin allows for a nice way to hold the needed parts and the whole thing is supported by the mounted choke.
The ultimate use of these boards is for providing DC to some coleman regs and here is the resulting waveform when drawing an amp and a half of current. Yes that is a 60mv p-p 120hz sine wave
Finally a picture of what is really going on.
