Albawinder

AlbaWinder - The Arduino Coil Winder

The AlbaWinder is a project developed to create a coil winder controlled by Arduino. It uses OpenBeam frame and components.
It is normally on sale here. - Pre-order possible if none available here.

CNC Sketch

Coming Soon. A sketch for controlling the winder via serial port is being developed. This will turn the AlbaWinder into a complete CNC machine. Your contribution is welcome if you wish to help.

The Control Circuit Board

The control circuit board host the following:
- Atmega 328 MCU (arduino)
- FTDI to USB adaptor.
- 6x push buttons
- 1x potentiometer
- 2x A4988 Stepper motor controller
- 1x i2c connector
- Power supply with switch (30Volts max)

Carrier position sensors

Two optical sensors are mounted behind the carrier to detect position. This is used to change the direction of the carrier when reaching the end of the coil. They are manually adjustable using the knob screw.
