We recently found an old novelty desk fan that could be programmed to display text and simple patterns. The fan had originally come with some proprietary software on an included CD that was designed for Windows 7. We decided to investigate and see if we could get the fan working again and potentially add some smart functionality. The fan appeared to be a generic item resold with some custom packaging by a distributor. The original tags on the rear side of the fan were unreadable and with no other visible markings, we decided to disassemble the fan to see if we could find any hints on the circuit board. The fan was easy to access with one bolt and nut securing the front grill which gave access to the blades. The control circuitry could then be partially separated from the main body of the fan by removing the three screws on the back securing it in place. This released the blades and revealed the inner circuitry to control and program the fan. We noticed a model number printed behind the LED strip used to display the programmed text and on the circuit board. The model number read UF, and after a quick search, confirmed our suspicions that the fan was indeed a generic widely available model.
