Fabio Varesano has designed what is probably the smallest Arduino compatible board. He writes: [via]
By using the QFN32 version of the ATMEGA 328p, 0.05″ connectors, 0402 components and removing everything not strictly necessary, I’ve been able to design and hand build an Arduino compatible board which is very small (20.7×15.2 mm) and ultra light (2g) but has exactly the same computing power of the Arduino Duemilanove or UNO.

Prototino ATMega328 Kit in the Maker Shed:
The Prototino ATMega328 kit is designed to make a permanent version of your Arduino project once you have perfected it on a breadboard but without the expense of embedding your original project. The Prototino also makes your project more reliable and robust. With the prototyping area integrated with the microprocessor, your project will have fewer boards and fewer wires.

mekonik has published complete details on his Arduino magnetic levitation project. Not content to settle for a typical “hello world” LED blinker as his first project, he supplemented the Arduino with an electromagnet, Honeywell SS19 Hall effect sensor, MC3401P op amp, NPN transistor and 1N4001 rectifier. The circuit essentially uses the small Hall effect sensor to sense the field of the permanent magnet and uses that information calculated by the Arduino to control the modulation of the magnetic field of the electromagnet. Pretty cool!

DOTKLOK is an open-source, hackable, Arduino-based digital clock that displays a series of unique time-telling animations. The passing of time is depicted with numbers and abstract/geometric patterns such as Morse code and minimal analog clock faces, and includes animations inspired by classic video games such as Pong, Tetris, Pacman, and Space Invaders.

This instructable will show you how to make an electronic dice with minimal experience using 7 LEDs, resistors, jumper wires, and of course the arduino (or arduino clone). I wrote this instructable for anyone to easily follow along and learn more about the arduino. Questions are welcome and will be answered as soon as possible. For less experienced users the code for the arduino is in “longhand” and several comments are included for better understanding of the code being uploaded into the arduino.

I used a ST7565 GLCD (Graphic Liquid Cristal Display) screen to display the live analog readings from an Arduino.

This project is about a quiz game that delivers electric shocks. It’s Flash based and uses an Arduino to control the hardware.
By now, maybe you are wondering: “What’s a Q&D-Poor man’s-Skinner-Sadist-Jeopardy game?, do I need one?, is it for me?” well, if you are ready to start an epic journey to the world of power, irresponsibility and electronics to create a device capable of make the players learn something by the always effective power of pain and shame… you might be ready to receive the knowledge.

This guide will take you through the steps to build an NES playing robot.
This is an arduino based bot which can play back tool assisted speedruns on the NES. If you’ve ever seen the “Super Mario Bros 3 beat in 11 minutes” video, think that, but being played back on the actual console. This bot can only handle the original Super Mario Bros currently, but it can beat it completely.
