Still under testing! I'm thinking that this device is useless after couple weeks of testing, but I love making it just for the sake of testing. Information [Demonstration](https://youtu.be/oo4phAcBv2w)...

Stepper driver A4988 runs the stepper in biploar mode instead of unipolar as the ULN2003 driver does, This adds about double the torque/speed. If there is interest I've got a design that works with ULN2003 for an even cheaper design... (personally I...

However, if you want to combine two linear systems into an X-Y plotter, it's better to use an Arduino board combined with two ULN2003 ICs. The motor and Arduino boards function very well at 4.5 volts (three AA or AAA batteries). Don't expect the...

* For 28BYJ-48 stepper design (quite slow, requires Arduino skills): + 28BYJ-48 stepper motor + ULN2003 driver board + Arduino or similar + stepper program (provided in files) + Two M6 nuts and bolts + Printed parts: one stepper adaptor and one...

To power the motors a ULN2803, ULN2003, or other driver that can directly handle unipolar steppers is required. Make sure it is just a driver as the control pulses come from the Raspberry Pi GPIO. ...Wire the two motors on the same outputs with the...

Hack your 28BYJ48 to work as a bipolar motor and use decent drivers (A4988 or DRV8825, not ULN2003). Mount an MK8 extruder gear on the motor making sure the filament channel is close to the motor. Then use two M3x8 screws to hold the motor in place....

Here's what you'll need: * Arduino Nano or clone * Stepper motor type 28BYJ-48 including driver PCB ULN2003 * 200mm closed "GT2" belt * Some sort of power supply (I use a single Li-Io cell, 3.7V) * 3 pushbuttons of any size for fast forward,...
