The live feed shows my home-made scrolling message board. This is hooked up to display your emails and Twitter messages. Please have a play! You need to send a Twitter message "@LEDcontrol" or send an email (with the message in the Subject) to controlmylights@googlemail.com. Note: it may take up to a minute for your message to show up, longer if there is a queue. Have fun!
For the technically minded, the messages are fetched and passed to a microcontroller board by a netbook running a Python application. The microcontroller board controlling the matrix is an Arduino2009 (Atmel Mega328P) and is programmed in C. The matrix board is constructed from five 8x8 LED displays, the columns are driven by five 74HC595 shift registers and the rows directly from the micro.
