Coil Question... need help

[Madebymonkeys]

Do you have a good source for Polyimide tape ?

Yeah, Farnell, RS, Newark, Digi-Key - they all sell it. If you don't have an account with any of these guys then eBay is also good - search for Kaptop Tape. TBH eBay is probably the cheapest source but delivery times are (as you probably know) variable - Farnell etc can normally deliver next day if ordered before 9pm (in the UK at least).
Incidentally, if you do buy components and materials regularly an account with one of the above is very useful!

Are you sending your coil to Mars?
If you are operating on Earth, then I would imagine that ordinary heatshrink tubing will be good enough. After all.... what is the wire itself insulated with, before and after your join?

Due to a bit of miscalculation on my part, one of my TinselKoils needed a couple of joints in the secondary. I used Kaptan-insulated wire-wrap wire for the coil itself, but for the joins I just used ordinary heat-shrink and a wrap of electrical tape for appearance sake. It works fine. But if I were going to Mars with it, I'd rewind the whole thing with a single length of wire.

In the photo below, the yellow wire on the lower half of the secondary is joined to the black wire on the upper half, underneath the band of red vinyl electrical tape. The actual shrink-wrapped joint can be seen as a little bump under the tape.

Seein as this threads about coils' Does anyone know why my coils hummig??
Anyone know away of dampening the pitch is too high it hurts please play
nice Mrs coil Mr rotor wants to raise your pulse! Stop whining! Could i put a znr capacitor across the
coil or something? I know its something to do with occilating?!

Hi colzilla,
I think your coils are loosely wound, applying electrical varnish will help...

Thanks. Got my first rotor spinning  weird thing is I got a 1.1 bifilia wound coil about
500 turns not sure awg driving with a reed switch.
Got it
positioned right took awile lol
anyway start of wind1 is connected to reed switch then the other end goes to ground. The end of wind 1 goes to positive. Nice and simple. Heres where I'm scratching my head.
Wind two goes straight to a bridge rectifier and the + - are connected to each other..
It doesn't stall or slow down it speeds up? Same thing with if I put a cap there.
Its weird..
I'm gonna hot glue my coil. Thanks. I guess its because its oscillating or something.
Cheers
