Hall Effect Coil Winder

at 5:38 am. Filed under Electronic Hacks

Counting winding turns is made easy with this project that uses a hall effect device.

“Magnets on a spinning thing near a hall effect latching switch chip make pulses that a counter counts to count the turns the spinning thing spun.

A latching hall effect switch turns ON when it sees one pole of a magnet.
Pull the magnet away and it stays ON.
When it sees the other pole of the magnet, it turns OFF.
And stays OFF untill it sees the first pole again.
