webboggles.com has designed a SSD1306 OLED Screen based game kit using an ATtiny85 microcontroller. They also sell it as a kit to assemble it yourself. The new snap case has been updated to allow enough height for the screen header as well as a factory made CR2032 battery...

Iain Sharp build this port of online Circuit Simulator based on Paul Falstad’s simulator, however Sharp’s version is built using HTML5 and requires no plugin to run. Think of it like animated Fritzing circuits, with a slew of pre-built circuits and components available for...

educ8s.tv wanted to take a look at this tiny board for a long time. It is very small size, it is low cost and it uses a different processor than the Arduino boards. It uses the ATTiny 85 microcontroller chip, which can operate at a frequency up to 20Mhz. It has 8Kb of flash memory,...

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...
