Home made Doug Coil Machine
These pictures were sent by a friend showing his Doug Coil Machine setup.
Dear Jim and Carol:
Here is a glimpse of what I have to go through to run a few different frequencies on my Doug machine. Notice I have 4 different coils that have to be combined with various capacitors to hit the harmonic. My setup is crude at best, but does work if I have the energy to use it. It is a challenge also to use my massive spread sheet and capacitor in series chart to try and match up the right capacitance to the right coil to hit the frequency I want. Just explaining it makes me tired! Hope to hear from you soon.
