Arduino shield board outline in gEDA format @ Low Voltage Labs. Eric writes:
I have been working on a few different shield boards for the Arduino platform. In an attempt to make life easier for myself I created a couple starter files for my future projects. The zip file below includes a schematic and PCB file in gEDA format. The board has the four headers and mounting holes for an Arduino shield board. I’ve decided to release the files into the wild for anyone to use.

This project created by Paul Bishop is a real time spectrum analyzer based on Arduino platform. The output is displayed on TV output. . He used an FFT library by Arduino forum user deif to convert an audio input into frequency data, and the TV out library to display the results. [via]

Patrick Mccabe’s build this Pong game based on Arduino board and 8×8 LED modules controlled by MAX7219CNG LED matrix driver IC from Maxim. The game is controlled using two potentiometers and is build using professionally made PCB boards. Each LED module has it’s own little control PCB. Check construction details on the link below.

Andrew Schamp has build a temperature datalogger to measure the temperature in his garden. He used a TC74 temperature sensor, 24AA1025 1024kbit EEPROM and a DS3231M+ real-time clock to record the time and temperature hourly onto the EEPROM. He also implemented a serial interface for reading the data at the end of the sampling period. The device is based on Arduino-compatible Boarduino. Every hour, the device takes a sample, and then goes to an extended sleep state, to be awoken an hour later by the interrupt from the RTC. [via]

This project is an automated Android controlled cat feeder based Arduino board. The attached HTC Magic is running SL4A and provides scheduled and on demand feeding as well as an MJPEG webcam feed. The Arduino is hooked up to a SparkFun BlueSMiRF and a simple relay circuit to control the motor. The brackets and food chute were designed in SketchUp and printed on MakerBot. Check it out on the links below. [via]

This project is a meter that measures your Internet connection bandwidth using an antique gauge. It is based on an old voltmeter and on Arduino board. A perl script is getting the information from a Linux router and send it to Arduino via serial connection emulated by FTDI chip. The Arduino convert it into a pulse width. To drive it full scale it needs about 10V and 150mA and that too much fro Arduino to handle, so it uses a switching amplifier made from transistors.
