A protoboard that fits in an Altoids Tin, by Laen.
A breakout board for the ADXL345 Accelerometer, by Laen.
LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available.
Essentially, its a very simple musical synthesizer that uses the conductive properties of pencil graphite to create different sounds. The result is a fun toy that lets you draw musical instruments on any piece of paper. By Ladyada.
Output selection switch to select from 3.3v, 5v and Adjustable. Onboard potentiometer for adjusting voltage from 1.25V up to within 0.5V of the input voltage. (20V max)
The Arduino itself is CC-licensed.
The Megavore is an Atmel AVR XMEGA 128A1 development board.
This a simple breakout board for button pads with holes for RGB LEDs. Each LED and button is brought out to the side connectors. The connectors are soldered to the back side of the PCB. This one has diodes for button isolation and easier decoding.
The AVR HV Rescue Shield is a high voltage parallel mode fuse programmer for Atmel AVR microcontrollers.
It currently supports the ATmega48/88/168/328P series and the ATtiny2313.
Botanicalls opens a new channel of communication between plants and humans, in an effort to promote successful inter-species understanding.
The Botanicalls project is fundamentally about communication between plants and people. We are empowering both by inventing new avenues of interaction. Plants that might otherwise be neglected are given the ability to call and text message people to request assistance. People who are unsure of their ability to effectively care for growing things are given visual and aural clues using common human methods of communication.
ClockIt is a basic alarm clock with buzzer based on the ever popular ATMega168.
It's meant to replace the existing controller board in any standard servo (~.78 inch servo width). With this board you can control a servo entirely with I2C/TWI commands rather than PWM, meaning that multiple OpenServos can be controlled with just two lines! The OpenServo firmware also offers some interesting control features, such as querying a servo with an unknown position, setting control gain discretely and on-the-fly, and even querying the destination of the actuator before it reaches it!
Open Source Brain Scanner. Woot!
Adapter boards for using MSOP10 or SSOP8 parts in a breadboard.
BSODomizer is a small, battery-powered, mischievous electronic gadget that interfaces between a laptop or desktop and VGA monitor and flashes a fake BSOD onto the monitor at random time intervals or when triggered. Here's my (Etharooni's) port of it.
The OSMC project was originally made for battlebot robots to power extremely high current DC motors. Like, 160 Amps continuous. Here's my version.
A useful little board that uses your computer's power supply (4.99 at Goodwill) and splits it out into high current, regulated 12, 5, 3.3, -5, and -12 volts.

All the JeeLabs designs are CC-By. He has some nice ideas about making Arduino clone peripherals more modular. And his boards are real purty :). Most recently the AA->3.3V power supply is pretty nice looking. If you don't feel like DIY, they're available stateside from Modern Device.
