The MIDI Piano Instructor
posted June 25 2010 19:59.53

Alessandro Lambardi created a tool aimed at improving the piano keyboard self-teaching experience with direct interaction between the student and software (or human, remote) teacher.
The new level of interaction is reached when the student is guided on the notes to play or exercise on visually with LEDs placed directly on top of the piano keys. A Personal Computer running music-teaching software or regular score composi...

WI-Radar Project
posted June 11 2010 19:34.42

AiFiLTr0 was frustrated by the wimax signal quality, so he went off making a good wimax antenna. He ended up using a biquad antenna, tuned for WiMax, This was easy but who was going to position it? The servo from a flatbed scanner gave the solution and now the wi-radar is born. The sources and PCB layouts will be posted here soon so stay tuned.

Arduino Gyroscope Mouse
posted June 7 2010 18:56.07

KuroMaii made an Arduino and Wii Nunchuck based gyroscope mouse imitation.
I can say that is one of the smoothest gyro mouse's i've seen. The "WiiChuck" adapter and functions code for Arduino came from TodBot.

Hack an optical mouse into a camera with Arduino and Processing
posted June 7 2010 17:34.28

ljandersson demonstrates a way to grab the frame buffer from an optical mouse with Arduino and use it as a small camera.
You can find the code and more details here.

LFS data on my Dashboard with Arduino
posted June 7 2010 17:24.21

herctrap used an arduino to read from the LFS (Live For Speed) game data such as rpm, speed, gear, turbo pressure, and fuel and made his own dashboard.
From the data he aquired he used 1 servo for the fuel indicator and a unipolar motor for the rpm that actuates also a shift light and one for the fuel indicator. The dashboard completes a 2x16 LCD screen showing current speed and current gear.

Lego Hello World
posted June 4 2010 12:19.38

horseattack using Lego as build material made a Lego printer with a marker as head. He made also the coding for communicating with his Apple Mac via usb and sent the images.
The video is a bit speeded up but the whole thing seems to work very well and with 75dpi accuracy as the maker says.

Robot with mouse for navigation
posted June 1 2010 15:22.15

Scott Sumpter presents an autonomous robot that uses as distance measurement an optical mouse for accurate readings. Actually there are two robots. the first one, equiped with 2 limit switches for object detection, navigates its way around an object, then communicates the path it took back to another robot, which can then avoid the object without sensors. More info can be found here.

ardPlayer Token - RFID reader and Arduino
posted May 25 2010 15:44.16

Alain V. made a simple project with an RFID reader attached to an arduino microcontroller which sends the commands to a pc and enables him by selecting different cards or tokens to start play a playlist or stop it. Nice, simple and does the job with a hi-tech touch. You can find all the info you need here.

DIY audio mixer with arduino and sensor board + processing
posted May 19 2010 11:54.23

Geoffroy Tremblay built a prototype of an audio mixer with and Arduino Board ~ connecting to processing, on a machine running puredyne os. The fact that arduino sends serial signals over USB which isnít understood by audio software emerged the need for a midi usb device, this device came on a kit to end needede electronics. The project needs a box but except this is fully operational. The whole story can be found here.
