In our project we have to use some 400 step/revolution, 3V stepper motors with 1.7A/phase (datasheet). We then decided to use the DRV8825 Stepper Motor Driver, which seemed like a good choice. In the ...
This easy-to-do hack allows motorists to keep their car windows from fogging up on chilly mornings, without the need to sit and wait for the heating to kick in and clear windscreens ...
Like other PCB motors it produces very little torque, roughly 2% of a typical NEMA17 stepper motor. Even so, the engineering behind this project remains impressive. Continue reading “High ...
