"An Arduino board can communicate with the Raspberry Pi via a serial over USB connection. This creates a virtual serial interface, which it uses like a normal interface, reading and writing to the serial device file."

"So I decided it was time to build a kegerator…More importantly, because I’m a nerd and I’ve never worked with an Arduino I decided it would be fun to play with one. I ended up with an Arduino controlling an LCD for each of the 3 taps I installed, displaying what beer is on tap and how much beer is left in the keg."

"The following page documents the construction of a rather large electric scooter for ‘semi-offroad’ use. My goal was to have something usable to zip over to a train station or grocery store, regardless of it was snowing goblets of ice outside. This project unfolded slowly over the course of ~18 months, in a start-stop fashion, as time became available."

"..Since I was going to be using an microcontroller to count the turns and stop the machine when the predetermined number of turns has been reached, I could make this winder do more stuff too. So, I made this pickup winder into more of a pickup winding station…"

"For our design project we constructed a polygraph which measured pulse rate, GSR, and breathing rate, and performed a discrete cosine transform on the subject’s voice in the hope of measuring a deviation in the fundamental frequency. The measurements were sampled, analyzed, and transmitted to a computer for further analysis using an ATMEL AVR Mega32 microcontroller."

"Here we show a little Theremin module which plugs onto a Arduino Board that gives out the tune to a speaker or puts out the tune as control signal like MIDI, Servo etc. We were using this device not only as a musical instrument, various kinds of proximity sensors, pointing devices or as interface in combination with Processing, Max or Pd have been build with this technique."

"Open.Theremin is a open hardware and open software project. You can build your own real theremin."

"For the past few weeks I’ve been working on the first stage of a project that involves hacking Eric Boyd’s excellent Heart Spark PCB pendant and combining it with a sensor module I’ve made from scratch."
