what happens between a teslacoil the battery the incadescent bulb and the ground

Hi everyone,

I've made some improvements to the TinselKoil circuit which has reduced the input power by close to half from the original demo.
Wound 3 new secondary TC of lower resistance (used 24 AWG instead of 33 AWG) which has helped in the most part (on transmitter) to lower the input power.
The other 2 identical (red) TC you'll see in the video were made to test the effect of adding multiple output loads on identically made and tuned TC to see if the bulb intensity reduces which it did by half.
So I decided to wind coils that I use to experiment with Resonance so 8 years ago. Once I found the correct balance between inductance and air capacitance I'm able to add a second load with no effect to the first load and the input current.
I think I can keep adding loads if the coil geometry, inductance, capacitance and load are identical. However, the problem now is I only have 2 identical variable air capacitors. It won't even work with a different make of air capacitor (which I have and tested) even if I tune it to the identical capacitance value.
I've also had no success in substituting the air capacitor with a regular capacitor of identical PF value.
So to further test the results of adding more loads to see how far it can go I'll have to try and make my own variable air capacitors.

Had to remove the Ferrite bead on the DC input power line as it got really hot, probably because of the new resonant frequency being 1.14MHz compared to the previous 750kHz.
If I hold (with my fingers) a 7w 120vac night light bulb and connect to the battery terminal the bulb fully lights but input current increases (no free lunch there)

Hi everyone,

I accidentally deleted the above test 2 video and can no longer edit my post, so here is the replacement link: https://youtu.be/kndYHIHSAE8

Hi Luc

so a lot of work winding those long coil.

How do you wind them , because i wound mine by hand and it took so much boring time?

And anyway fantastic results, i have just dismanteled a vintage radio and got out the variable air capacitor which is 2 time 30 up to 500 PF, and will try to tune a coil receiver for my little Tesla coil.

Very intersting stuff there

Keep up the good work

Hi Laurent

All the coils are hand wound for now. Once I know what I want and need to make many I'll build a mechanical winder.

Don't take too many old radios apart just for this, since once I've find a substitute for the variable air capacitor I'll post a video demo.

Maybe in a few days I'll make a video demo of how I test and tune these pickup coils.

Hi everyone,


Still moving forward with the same ideal of trying to add as many tuned receiver circuits as I can.
