Inspired by http://tinkerlog.com/2009/04/05/driving-an-led-with-or-without-a-resistor/ I started to build a USB driven display. I ordered some big green 5×7 dotmatrix display from http://evilmadscience.com/ and had a look at v-usb.

What you get when combining those is a via USB controllable dotmatrix display. The PC related programming I did in Python using libusb and the python binding called pyusb. So the program should be cross platform compatible! Also python allows one to extend the functionality(e.g. checking for new mail, usb notifications of any type…) very easy.

avrDotmatrix uses a 5×7 dotmatrix display and an ATMega8 to create a nice display with scrolling!

avrDotmatrix – Is a 5×7 LED Matrix Display controlled by a ATMega8 to display scrolling text, time or temperatures. The pattern is generated with multiplexing the 5 matrix columns and setting the correct row bits.

This projects is still in development and i’m gonna add a temperature sensor (LM75), a I2C EEProm and maybe a IR receiver for transmitting texts to the display wireless.
