guitar pickup winder

A simple way to count the turns of wire when winding a guitar pickup. A pair of cam operated contacts that are wired to the left click of a mouse, Windows calculator is set up with 1+1 then th mouse cursor is placed over the = sign. A simple counter.

how didi you tied up the bobbin to the wood?

[Splundo]

@coconuts8866 just a small drop of hot glue, gently ease

it off with a screwdriver when its finished.

How does the counter part on the drill itself work? It seems to me like two parallel pieces of wire are dragged over the cylinder. The cylinder has tape over it except for a little tripe, were it has aluminum foil. When the aluminum side faces up, both wires touch it, so the cycle is complete.

Is this right or have I just designed another counting mechanism?

[Splundo]

The two brass rods are about 1mm apart, there is a small piece of metal taped to the chuck of the drill, effectively acting as a cam to close the gap between the two brass strips and create an electrical contact.

This seems really brilliant to me.

Now for the sad part. I feel really stupid. What's the mechanism for closing the circuit every turn? I know, it had something to do with the wires, but I really can't figure out much more.

[Splundo]

The mechanism is simply 2 small brass tubes set with a small gap between them. As the drill chuck rotates there is a small piece of wood taped to it that hits one of the tubes causing it to contact with its neighbour, similar idea to old cars that use cam operated "points". I would recomend using something more reliable like a micro switch.

@Splundo

I use double sided carpet tape. Its great!

[PlatypusVomit]

That's brilliant. So simple. Thanks!

@ESPRITCAM5AXIS It's the mouse! He just has the cursor on the "="

Brilliant!

[MrDarinWarren]

Well done. 

[guitarherorawks20]

Hahaha that's amazing!!

[cast390]

Awesome,....You're a fucking genius

[rokinrandy]

Even if I did rig this up I still would not know how to do this..I don't even see a counter function on the ms calculator on my computer..This is very puzzling..I wish you had an article on this because I want to do this..Great job

[JPM100P3]

Brilliant! excellent! is a great Idea! I'll apply something like this on my own project!
