Steve gave 2 of the 3 MAXIM 6953 chips to Nick and kept one to experiment with. Nick is gonna get some IR LEDs and make sure they actually are visible thru a digital camera outside during daylight so as to make sure it's worth it to buy all those LEDs.

March 2, 2011 Nick clued us in to the handy MAXIM 6953 5x7 LED display driver. After some Googling which at times lead us to MAXIM magazine, Nick and Steve put in an order on MAXIM's site for 3 free samples, which should arrive at Steve's house soon.

March 9, 2011 Steve gave 2 of the 3 MAXIM 6953 chips to Nick and kept one to experiment with. Nick is gonna get some IR LEDs and make sure they actually are visible thru a digital camera outside during daylight so as to make sure it's worth it to buy all those LEDs.

Design notes

5x7 characters Will have 4 characters scrolling

Driver chip: MAXIM 6953 This uses a pretty basic serial interface to drive the LEDs (I2C) There is a character set defined in ROM. Users can define their own symbols or use the user defined characters to implement scrolling, but doing so requires a crudload of code.

Here's a nifty project somebody did

IR LEDS front of box will be covered w/ lens, trashbag, something like that

Software

Programming this is very easy via an Arduino. See
