Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

using an Arduino shield, a couple of second hand DC servo motors and a couple of wooden wine boxes a fantastic Arduino CNC plotter has been created and published ...

It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’. Mine has a ~230V 150W brushed dc motor that needs driving from 240Vac mains power. Almost randomly, I settled on a ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...
