Led fan editor download1/5/2023 The 512 byte version leaves the A0 pin unconnected and that bit in the EEPROM slave address is reserved for the high bit of the memory address. I'm assuming they use the same fan PCB with the smaller EEPROMs and use the other address bit for some reason. The PA0 pin threw me for a little bit, but it is connected to what would be the A0 address pin on the EEPROM for smaller chips in the same line. On the back side of the PCB, the 5 pin port was labeled:, and I confirmed that these pins were connected to the I2C SDA and SCL pins on the EEPROM. Whatever microcontroller is being used is under a black blob, but the SOIC-8 IC with a marking on it was a, which is a 4kbit (512 byte) I2C EEPROM. This was a very simple project, but it was fun to figure out how something worked and then make it do something else. I searched online and found that were re programmable, but those had 4 buttons for programming in messages, and mine only has an on/off button. The box it came in says 'Programmable Message Fan: Model 45 Series'. The fan itself is pretty cool.but I wanted to see if I could make it say something else. The fan has clear, flexible plastic blades, and one of the blades has a strip of 7 LEDs in it which are used to display the messages. The company where I work has recently been doing a big push for safety, and last week they passed out small POV fans with sayings like, “Thx 4 Being Safe”, “Being Safe is Cool”, “I'm a Safety Fan”, etc. Led (LDAP Editor) Led is a general purpose LDAP editor which allows editing of LDIF records or standard unix flat file.
