Find Me On:
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
bother with
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.
looking at this chart. I can
estimate the total output voltage at the top of the secondary coil
to be over 15 thousand
Tesla Coil Safety. (Good idea)
