You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Electronic speed controller with arduino project illustrate a physical 3-phase motor driver system. It features high current MOSFETS, dual MOSFET drivers, and an arduino nano. A DIY motor driver board ...

I have a friend (stop laughing -- it’s true -- I’m not going to proceed unless you get yourself under control -- thank you). We will call my friend Guido Bonelli (because that’s his name). Guido has ...

[Jesse Merritt] bought a manual speed controller for his router. It’s used in the CNC mill he build and he figured, why not add the ability for the computer to control the speed. The speed controller ...
