Here is a great Raspberry Pi based Reflow oven controller from "apollo-ng" on GitHub. You can edit your temperature curve on your browser and Rasberry Pi controls the solid state relays and fan. Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller. Of...

This project is about an accurate mains frequency meter that has a bar-graph displaying the relative deviation from nominal frequency. It can work with 50Hz and 60Hz systems. An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out....

Øyvind Nydal Dahl show us how to use an IR remote control with Arduino. For this purpose he connects a TSOP312 and an IR LED to Arduino and goes in detail on the sketches. In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this project...

Make your own logic analyzer using BeagleBone board. Software is where the magic happens. There is a pre-made image for the BeagleBone with everything loaded and configured to use the BeagleLogic. It’s a recent image based on Debian instead of the older Armstrong builds. The nice...
