Today I finished printing the parts but could not do much to assembly as  I still feel like shit

I printed two flanges

The coil former

5 wire direction wheels

Two cones for holding the bobins

And a small screw cover to center the axis on the other side

Today I feel much better… lost about 5kg of health this days

I’m about to put the automatic coil machine to work

Just hopping it will work as expected

I’m going to try making a video of the bifilar coil that is on the prototype



 ;)

Hey there, I didnt uploaded the video because was too long and didn’t show much

I decided to make another video in a live on YouTube so it’s recorded at once

In the tests I show the working of the resonance and try to detect some feedback

I use a 100nf capacitor that brings the resonance to 9khz with the 2.8mh bifilar

I will start the live tests in within 1 hour

If you want send live questions

Hope you like the video

I was able to show that the feedback kind of indicate some frequency

Some tvs burned so the resistor was getting most the power at the end of the live

Probably after that smoking point

A better coupling of secondary with primary would make it work much better transferring power

Also like I said on video having Better wire diameter resistances would improve protection and transfer

Making it a non dissipative snubber may also be a better way to go because the capacitor is competing with the power that should going out

So I may give some improvements to hit harder

I got to conclude that having a low Q factor makes it harder to get resonance with some power in it

The high resistance ratio makes it hard to make it develop a current cause it would need to dissipate power

Hope the big coils I’m making have much higher reactance

What your ideas of that feedback signal popping ?
