This POV Fan Display Hack by Hacking with Gum required a bit of reverse engineering to determine how the device worked in the first place, then a way to re-program the operation of the device to display a new message. Thanks Craig. "It turns out that Cenzic made it very easy to access the fan’s EEPROM chip, and with a simple RS232-to-I2C interface you can re-write the EEPROM on this device to make it display whatever you like.

Great Article! I was given a bunch of these pov fans with message already installed and was poking around for a hack to be able to reprogram them. Problem is that mine are found with a five not four pin header. Are they the same with different header? Or are they using a different chip and method of programming? USB? I will disect one to see what all is inside, maybe it is the same chip with extra gnd, lol. If hackable might be a great learning project for students…
