Micro Maestro 6-Channel USB Servo Controller

The Micro Maestro is the first of Pololu’s second-generation USB servo controllers. The board supports three control methods — USB for direct connection to a PC, TTL serial for use with embedded systems, and internal scripting for self-contained, host controller-free applications — and channels that can be configured as servo outputs for use with radio control (RC) servos or electronic speed controls (ESCs) ...

DIY Six Channel Arduino RC Transmitter

It’s wasn’t so long ago that RC transmitters, at least ones worth owning, were expensive pieces of gear. Even more recently than that, the idea of an RC transmitter running an open source firmware would have been considered a pipe dream. Yet today buying cheap imported transmitters and flashing a community developed firmware (if it didn’t come with it pre-installed to begin with) is common place. It’s not m ...

Fart Operated Random Channel TV Remote using an Arduino

OK, I know that sounds weird, but bear with me for a moment.  My Pops really enjoys two things; 1) channel surfing and 2) farting. So one day I was over at http://hackaday.com/ and read about a guy who used his Arduino to turn a TV on and off with one of those brainwave reading headsets.  Then later on that same day I was here at Instructables and a fellow had made an office chair that twitters every time h ...
