"AutoResetRRR is a kind electronic frustration reducing device: it cuts the power periodically to devices that can go nuts (routers, net cams, servers), but it does give a heads up. If all is well, they can shut down safely and start back up. If not, the power cycle can fix a thing or two."

PWM Dimmer for LED Lighting

Posted May 4, 2016 by Chris

"I have recently moved to a new apartment and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be easy enough nowadays but it proved more difficult than I thought. All I found either didn’t meet my requirements, were uggly or expensive. So I decided to build my own, tailor-made to my needs."

Home-made GPS and compass

Posted April 18, 2016 by Chris

"This is a project I started about a week or so ago and have been working on when I find time after work. It’s a GPS and compass that temporarily uses an Arduino Nano micro-controller, Nokia 3310 screen, EM-406A SiRF III GPS receiver, and a simple (non-tilt compensated) magnetometer for compass heading."

Raspberry Pi GPIO driving Servo

Posted March 9, 2016 by Chris

"I have experimented with GPIO on the Raspberry Pi, just turning an LED on and off here. But since then Ben Croston has improved the RPi GPIO Python library to do most of the work in C and I can confirm that it is a lot faster. Driving servo motors requires precise timing, so I decided to see how the Pi would perform this task."

Dual Motor L298 H-Bridge Motor Control

Posted February 9, 2016 by Chris

"Dual Motor L298 H-Bridge Control project can control two DC motors connected to it. The circuit has been designed around popular dual H-Bridge L298 from ST. This circuit has current sense resistors for both H-bridges to provide voltage which enables this board to use in stepper motor applications."
