Arduino-sourced PWM-based speed control is a bit more tricky ... someone called H Holden has published a detailed analysis of a mosfet chopper style dc motor controller.

Once upon a time, brushed DC ... motor windings. To control speed, the controller adjusts the average voltage applied to the motor. A higher voltage generally leads to a faster speed. It does this ...

This project presents the design and implementation of a dual-fan PWM cooling circuit ... that converts universal 85V–260V AC to a stable 12V DC output, and a microcontroller-based control unit ...

The secret? Rather than using servos, dARM uses brushless DC (BLDC) motors paired with ODrive S1 controllers. He credits [James Bruton] and [Skyentific] (two names which regular Hackaday readers ...

DC vs RCB, IPL 2025: The Delhi Capitals will take on the Royal Challengers Bengaluru in their ninth league fixture of the IPL 2025 season on Sunday, April 27. The high-stake clash is set to be ...

In any event, he’s created a visual feast — never in history has an AC/DC adapter been photographed so completely and tastefully. An Ode to the Diode [Brian] even goes so far as to include ...

This project presents the design and implementation of an 85V–260V AC to 5V/12V DC, 24W Flyback Switching Power Supply utilizing the DK125 controller. This project presents the design and ...

Jesse used ODrive S1 motor controllers to control the brushless DC motors in the robotic arm. There are eight of these controllers, and they’re all connected using CAN bus. This whole setup is linked ...

Secondly, according to the relationship among bus current, switching state and phase current, a single bus resistance sampling current reconstruction scheme without current sensors is adopted, which ...

SimpleFOC + Halls + 2304 drivers + TO-220 mosfets or IGBTs. Plugs directly into 450x automower motors. Trying for low cost + lots of flexibility + solder it at home + repairable. Works as a 3x DC ...
