This may be the first ever Arduino MEGA 'hack" ?
Here I have used two 16 wire ribbon cables to break-out the large 32 pin double row connector on the right side of the Arduino MEGA. This is a 32 position IDC connector with extra long male-male pins going down into the Arduino, on the other side I used two 16 pin DIP style connectors.
More info about the MEGA here.
Arduino Mega 2560, with wires soldered to headers. This is a prototype, the finished project will be much cleaner.
My breadboarding is too damn messy. This is an attempt at an Arduino-driven EEPROM programmer (yes, silly, I know). It's controlled via USB by my PC.
Alright, I admit it. I just like watching the lights blink, OK?
Arduino Duemilanove, WiShield and a Protoshield. Nothing attached to the headers on the protoshield at this point however they will attach to the remote control for the Power Relays.
Here's the diagram of my arduino photolab box. More details here (in french) :

This is the first iteration of my Arduino ( a user programmable micro controller) powered flash trigger. There is an IR beam over the end of the barrel, the pellet breaks the beam and fires the flash gun to freeze the motion of the bullet. All I need to do now is set it up in the dark, and find a suitable target.
Looking to build an Internet connected device? The Arduino Ethernet is the ticket, with an Arduino UNO paired with an ethernet port it's the perfect piece of hardware to experiment with the Internet of Things. Or if you've developed something using an Arduino and an Ethernet shield it can be ported to this board with no code changes (uses the same WizNet W5100 controller).

Connecting an Arduino and Raspberry Pi to create a webpage with temperature and humidity measurements.
Elaborado sobre plástico flexible, este Arduino es un ejemplo de lo que se puede hacer siguiendo la técnica de David, autor del blog sewboard.cancamusa.net/
Using two 4051 multiplexer ICs I am able to simulate the electric typewriter's keyboard matrix and can control the entire functionality of this machine via the Arduino board.
This example shows the result of a tool that tries to recreate an image with the available letters on the daisy wheel. It types several layers of type over each other and also uses half-letter spacing and half-line feeds to cover more paper with carbon. The principle of this is demonstrated here: incubator.quasimondo.com/DarwinCss.html
3rd iteration of "Counter Intelligence" project. For best results with Maxbotic rangefinders I'd recommend the Lilypad. Parts from Sparkfun. Backlit 2x17 driven from serial interface of Lilypad.
My latest addition, 2 Arduino boards. Intended to learn the C language and the new hardware tools. I hope to have everything still working together with Lego and Fischertechnik. The top picture is the Arduino Giga R1 Wifi, the bottom one is the Arduino Due.
Both boards are already working and I am now making measurements with the PicoScope. I also still have the old Arduino Uno to make comparisons. Both new boards are 3.3V, the old Arduino Uno is still 5V. That's going to take some attention!
I know everyone has done this before. RFID and arduino that is. But looking at the example code it looks like the antenna is always in receive mode. I am not sure how this affects the life of the chip / reader but I thought of adding a way to detect human presence before activating the receiver.
I found some little IR heat detector (here: www.allelectronics.com/make-a-store/item/IRD-10/INFRARED-... and tossed together some analog read code and viola. Now when the IR detector detects over a certain variable heat temp it activates the RFID reader.
I will post the code and write up on my blog.
