Bus Pirate: Modifying the EEPROM on a LED POV fan

Posted on Friday, October 28th, 2011 in Bus Pirate by DP

MrZor decided to find some use for his Bus Pirate. After dissembling a LED POV fan he figured out that it uses a 24LC02B EEPROM chip to store the text displayed on the device.

The 24LC02B is a I2C device so he used the I2C mode of the Bus Pirate to interface with it. After some deciphering he figured out the code used by the device and uploaded his text. The result can be seen above, and the tutorial on how he went about doing it can be found on the forum.
