Hardware

I used a Atmel at90usb162 because i have a bunch laying around, also they are easy to get running and can be programmed over USB from factory. I simply made a PCB with these connections to replace PIC:

• LED R -> PC6/OC.1A
• LED G -> PC5/OC.1B
• LED B -> PB7/OC.1C
• Hard fade -> PD7/HWB/INT7
• Power -> RESET
• Soft fade -> PD6/INT6

The pot is removed all together because at90usb162 don't have any ADC, and i need the space to fit my PCB.

BOM

• 1x IKEA DIODER (the new kind with soft-fade)
• A piece of PCB, 0,8 mm thick about 23 x 27 mm big
• 1x AT90USB162 TQFP32
• 1x 8MHz HC49UP SMD crystal
• 2x 22pF 0805 ceramic cap
• 1x 100nF 0805 ceramic cap
• 1x 1µF 1206 ceramic cap
• 2x 22 Ohm 0805 resistor
• 1x USB Cable (to be chopped up)
• Some wire wrap-wire

Software

Firmware

The firmware is based on LUFA's GenericHID. It takes commands over HID (not serial) like "r7F" to set red to 0x7F, 127 or 50% (what ever you want to call it) or A00ffFF to set red to 0% and blue and green to 100 %.

Tools

dioder_lib.py

This is a python library that let you use dioder in a simple manner.

dioder_cli.py

A simple cli to control DIODER like this:

	$ dioder_cli.py R00
	$ dioder_bli.py G3F
	$ dioder_cli.py bff
	$ dioder_cli.py A123aBc
		

dioder_gtk.py

A tiny GTK application to control DIODER with buttons and sliders.

dioder_pulse.py

Audio visualizer based on Ian Halpern's Impulse. Controls the leds in RGB or HSV mode. Lots of command line parameters.
