Model T Buzz Coil - Induction Coil

This is a Model T Buzz Coil Reproduction shown In operation.
A 12 volt battery with a one ohm 10 watt current limiting resistor is the power source. The spark gap needs to be rather small since the insulation on these coils is not as robust as modern coils and will fail if too large.

The background on my channel is an electro-photograph that I made of my hands using a similar setup. I used a standard ignition coil running on 6 volts thru a glass plate with the Al foil and maybe a black piece of construction paper to block reflections. The film was Ektachrome 64. It was a slightly shocking experience! More so when I was barefoot. Tried using an AC flyback, it worked but was monochrome and not as interesting as the induction coil experiment.

The capacitor in my coil is a .25uF 400volt unit. One place you can get coils and parts is snydersantiqueauto(dot com)/modeltparts/coilbox.The coils are pricey.

i love vibrator driven coils so much better than a stack of silicon chips

@prototype9000 Me too. I've used electronic drivers with some success, but the mechanical interrupters don't let out smoke and stop working.

I used to own several of these Ford induction coils.  I played around with one in the photo lab of my high school back in the 70's, and used it for Kirlian Photography experiments. Instead of messing with film I just laid black+white photo print paper on top of my electrode (Metal foil under an 1/8 inch sheet of plexiglas), placed the subject on top of the paper, then touched the subject to ground it. It actually worked pretty well.

I expected a lower frequency - like a loud audible buzz. I didn't know mechanical switching could be this quiet.

Please let me know the expect of the capacitor and the supplier. Thank for the video. Take look at my videos. Happy new year.
