I wanted to give the challenge a shot of operating a Tesla coil that works on just a single 1.5 volt DC battery. The yield of this Tesla coil produces flashes of around 1 inch long. This
test was an individual task to check whether I could get a Tesla coil working with the most little requiring current. So maybe later on with some minor adjustments I could drive it
perhaps with the encompassing energies around me and couple into those sources (Ambient and Radiant)
Here is the typical schematic of the Tesla
Coil like the one I built.
My high voltage source consists of a flyback type of oscillator circuit. Secured and sealed in black module.
Based on a simple flyback circuit such as the one I used with the "Fruit High Voltage Experiment" My input source power is just one AA half dead battery. I'm able to get a 1kv
spark gap with this setup.
Building the Tesla coil high impedance
secondary was simple. I just used what ever I had around as a
core and wound as many turns of insulated copper wire. I did not
trying to calculate the optimal L/C values before hand. I wanted to keep things very simple. Tuning was done simply by adjusting the top capacitor hat dimensional lengths. Until
I got the best spark. This indicates the strongest point of resonance. Without needing any fancy tools or lab test equipment.
Tesla Coil Safety. (Good idea)
