Summary

This is an automatic winding machine for coiling up small cords, strings or wire. We needed a way to reliably coil up specific lengths of cord for sale in a kit.

The rotary encoder keeps track of the distance coiled with a closed loop system. This allows more fool proof operation, recovery if the spool hangs up or jams, and the ability to adjust the diameter of the coil without having to change the code.

There are two versions, one with arcade buttons and the other with a housing for 4 tactile buttons and an LCD display. I ultimately with the button style setup to save time programming and teaching the operator to use it.

Firmware is included for the button version, buttons and additional lengths can be added more or less indefinitely.
