Agentgates´s TPU setup with strange wavehill hump

[Magluvin]

I agree Mk
tonys new coil seems way off that, It seems less tall and wider.

Use current limiter and please read the post of mine on error checking.

I posted a formula a few days ago when somebody posted thos nice 3D images first on how to calculate the tube length.

for 45 degrees:
l = (d x PI)/6

"l" gives you the length to cut.

BTW: the importance of angle is not that vital, we just want to focus on precise job to minimise errors

Tony any updates on your progress since your last failure? Do you need any arduino help or something?

I believe that the coil height works out to be the coil circumference divided by 4. It worked for me.

I didn't touch the Arduino yet, just set it to 3 phase 120 degrees out-of-phase and 87Hz. It is not a tricky freq, just this is what the arduino gave first, so I didn't mess with it yet.

I had to rewind Stefan's coil with secondary first and primary after as the secondary is very thick to bend it on thin wires without causing damage. Unfortunatelly I did, so I removed the primary, cleaned the tube and glueing the secondary on the acrylic right now to make sure it doesn move. In the meantime I went ot town to buy some materials have depleated.
