Fresh hacks every day
Here’s a nice little circuit that will drive a motor and allow you to stop its rotation, giving your robot a set of brakes. It’s part of [JM's] post about the in’s and out’s of building microcontroller friendly motor controllers (translated).
This particular setup is a half H-bridge. It allows you to drive the motor in one direction … Read the rest
Brushless motors and the way in which they are controlled can be a bit of an enigma to those just starting out in hobby electronics. [Andrew] from spingarage thought it would be helpful to put together a quick tutorial showing how he built a simple brushless motor controller in about a day’s time. He constructs everything on protoboard from components … Read the rest
