DIY 3D printed coil winder using ESP32

This device eases the work with coils. In the following videos I will make solenoid and other types of coils with the help of this device.

Non 3D printed parts:

LM8UU
8mm steel rod
NEMA 17 stepper motors, one with threaded rod
MGN12 linear rail (can be skipped)
M3 nuts and bolts
M4 nuts

ESP32 WROOM 32
2 x DRV8825 stepper motor dirvers
2 x 220uF for the DRV8825 carrier

For the 5V voltage regulator, check "typical application" figure:

1 x LM2575 - 5V (T0-220 package)
1 x 100uF capacitor
1 x 300uF capacitor
1 x 330uH coil
1 x 1N5819 diode

Simple low dropout regulator for the ESP32
AMS1117 or LM1117 - 3V3 regulator

1 x 1206 red SMD led
1 x 1206 blue SMD led
2 x 150R resistor

The both source code is available in my GitHub repository.

One for the ESP32 and the other is a host application written in C++
You will need Qt framework for the host to compile.
