If you follow the world of small microcontrollers you will certainly be familiar with the usual fare of Atmel, ARM Cortex, PIC, and others. But these aren’t the smallest or …read more Continue reading The Three Cent Motor Controller
Brushless motors can offer impressive torque-to-size ratios, and when combined with complex drive control and sensor feedback, exciting things become possible that expand the usual ideas of what motors can accomplish. For example, to use a DC motor in a robot leg, one might expect to need a gearbox, a …read more

Rotation. Motors rotate. Potentiometers and variable capacitors often rotate. It is a common task to have to rotate something remotely or measure the rotation of something. If I asked you today to rotate a volume control remotely, for example, you might offer up an open loop stepper motor or an RC-style servo. If you wanted to measure a rotation, you’d likely use some sort of optical or mechanical encoder. However, there’s a much older way to do those same tasks and one that still sees use in some equipment: a synchro.
The synchro dates back to the early 1900s when …read more

Every Friday, the Hackaday.io community gathers ’round the fireplace and discusses the challenges facing the world. This is the Hack Chat, and in previous incarnations, we’ve talked about custom silicon, Arduinos, PCB fabrication, old technologies, and hardware manufacturing.
For this week’s Hack Chat, we’re opening up a design challenge. We’re asking the community for help on developing a wireless position sensor. This is a Design Slam Hack Chat, and we’re looking for contributors.
Our guest for this week’s Hack Chat will be [Naveen Nair], technology leader for GE Fuse. We’ll be discussing position sensors during this Hack Chat. If you’ve …read more
