PROPTB6612FNG

I uploaded (and also on OBEX) a little SPIN script to use the Thosiba TB6612FNG dual motor controller on the Parallax Propeller. The driver offers methods to operate each motor individually or both motors together (by sending the same command to each, or sending a different command to each).

ROCKETuC Introduction

I just made two short videos introducing the main features of the ROCKETuC project I work on with Alexander Reben. The first one gives a basic introduction to ROCKETuC and what you can do with it, the second one shows how external interrupts could be used with ROCKETuC and Processing. Basically I made them to […]

The Glowing eBunny – Happy Easter

This is just a quick little Easter hack. My wife brought in two cute little glass Easter bunnies lately, and they really demanded for a mod. Well then. The bunnies got a blue LED implanted each, the LEDs where connected to a MSP430G2231 MCU, and the MCU is driven by a small firmware which pulses […]

Tutorial on Driving a Servo through PWM

I wrote up my learnings on how to drive a servo in a little tutorial. The tutorial describes how to drive two servos (e.g. for a pan-tilt unit) through a PWM signal on an ARM Conrtex-M3. The example firmware described uses “libopencm3” as a basis. See the video below to get a glue what the […]

Pulse-width Modulation

On Non-Lexical Vocables there is a easy to follow tutorial on PWM. Or see the PWM video tutorial on afromods page.
