StrobeDuino - Computer-controlled RGB strobe/lamp

After experimenting with Arduino and Processing serial communication i wanted to do something cool. I had some RGB LEDs lying around so i thought about making something with them. I ended up with a strobe/lamp controlled by a Processing sketch that receives the commands from a Hercules DJ Control Steel MIDI controller.
It uses 2 3W RGB LEDs, 6 constant current drivers to ensure every LED gets the proper current and an ATMEGA8. It uses a RS232 interface and a RS232 <-> USB  converter to communicate with the computer.

It's got three modes:

Normal mode - This allows the user to manually change red, green and blue and if the strobe frequency is more than 0 it blinks like a strobe (with adjustable duty cycle).
Fading mode - Fades between colors (hue).
Fading strobe mode - If the strobe frequency is 0 it acts like fading mode, but if it's more than 0 it blink like a strobe, with adjustable duty cycle fading the strobe color.

Step 1: Parts & Tools

You will need the following tools:

- Soldering iron (to solder)
- Dremel/Dremel-like tool (to drill and cut the enclosure)

You'll also need some solder. Now on to the parts.
If you haven't got an Arduino or you want to make yourself a board for this project, you'll need:

1x 10K 1/4W Resistor
2x 1K 1/4W Resistor
4x 1uF 25V Electrolytic Capacitor
1x 100uF 25V Electrolytic Capacitor
3x 100nF 25V Multilayer Capacitor
2x 22pF 25V Ceramic Capacitor
1x 16MHz Crystal
1x MAX232
1x ATMEGA8/ATMEGA48/ATMEGA88/ATMEGA168/ATMEGA328 (NOTE: ATMEGA48 can't have a bootloader and it's flash is too small for this project)
1x RS232 DB9 Connector
1x Power supply connector (depends on your power supply)

For the LED driver you need:

6x 1,2 Ohm 1W Resistor
6x 47 Ohm 1/4 Resistor
6x 100 Ohm Trimmer
6x 4,3V Zener Diode
2x LM324

I used 2 3W RGB LEDs I bought from Dealextreme.

The enclosure is from Futura Elettronica (an Italian company), product code AUS11.

I attach a ZIP with all the project files in it.
