Fibonacci, platonic solids and Vortex coils

A picture please .

But recommendation time now .

First the tube paper only .

Second the pickup A wire needs to be really fat(serious anything in the twenties is useless)  , my jt coil gauge is about 24 , i would get better result out of 22.

The more turns you can get away with the better , you will need 2 for the jt.

edit

Are you Aussie (the use of the word mate), because i am up north the winding direction may not be proper . that would be funny .

The angle you used ? and make sure you try the coil both ways.

Winding direction?  Is this an American joke where I need to check which direction my toilet is flowing before winding my coil for maximum performance?  LOL

Yes, I did flip the leads around a little and there was a SLIGHT variation in performance, not much though.

I hope it is a joke , but a Canadian one

I have found this interesting ...

Ayrton-Perry winding - type of bifilar winding made of two parts wound in opposing
directions and connected in parallel.

1. Advantages

Such winding allows making wire resistors with the lowest values of
parasitic inductance and parasitic capacitance. [1]

2. Drawbacks

Because the two parts of resistive wire are connected in
parallel, the total resistance is half of the value
of resistors made in common technology (with the same dimensions).

3. Use

Resistors with Ayrton-Perry winding are used in high-frequency electronic
circuits, in which parasitic
effects would have non-permissible effects on the circuit performance.

Have a look at this , a honeycomb coil usually 3 wires , perfect for 3 freq.

They where used in tube radio , i wonder if they ever used it in tv sets.

The over all size of it is quite reveling and i know what that geometry dose .

The next step will be to make one of those with the secondary inside to honeycomb coil .

My jig is ready , i just nee to find the wire...

Beautiful coil design but way to complicated for hehe.....
