The EqualizerShield is a project from Matt and Chris for a 10x10 blue LED matrix that is intercompatible with the Arduino, Freeduino, and Illuminato.

It has two modes, one for a built-in 8-channel analog equalizer, and one for a serial-controlled LED matrix. Click here to buy & build

This project and hardware idea came from Mark, and it's designed by Matt and Mike. It is a 26 button keypad shield for DIY projects like the Arduino, Freeduion, Illuminato, and Basic STAMP.

The 26 buttons are multiplexed down to 5 signals that can be read simulatenously and polled by a microcontroller. One of the buttons doubles as a function key. When it's pressed, 5 other keys become shift-mode signals. Click here to buy & build

An extension card for the Arduino-platform (including Freeduino's and the Illuminato and similar boards).

This board allows two modular extensions to be wired into the Arduino base, or it can provide more prototyping area and soldering breadboarding area. Click here to buy & build

Another supporting device suggestion from Mark, for his advanced Arduino-based DIY projects. This provides more prototyping area for hardware projects. Click here to buy & build

The Illuminato is an AVR based chip, much like the Arduino, and is 100% Open Source - GNU GPL, that is. It has 42 I/O pins, more than any other Arduino clone out there right now, and even works with all the shields built for the Arduino. It has a 16 MHz oscillating crystal (the same as the Arduino), but 64K code space (twice the space) since I tend to run out room when building larger projects.

In keeping with the Italian heritage of the Arduino community, this board is called the Illuminato. This also doubles for the fact that there's a hidden (so to speak) function in the core called bling(), which turns on the backlight array of 10 white, high brightness LED's.

This was the first round of Illuminato's built, half-pre-funded, and the other half funded by pre-build funded by Matt, Justin, and Mike.

This idea and schematics submitted by Tim is for a standalone Open Source 5 megapixel camera powered by a TI processor.

The initial design is for a single camera element, paired with a battery on one side of the PCB, and a SD card and OLED screen on the other side. Click here to help design the hardware
