Battery Fan

I just passed by the petrol station kiosk and saw this battery operated fan. As it was only RM2.50, I could not resist and bought it. It looked like a very good potential for a handheld prop, maybe a medical scanner.

Not only that, once I diassemble it, I would get a free motor as well. And since the battery compartment is nicely moulded, I can either use back the same batteries or retro-fit it with the squarish 9v battery. The circuit must be small enough, using a microprocessor instead of the normal off-the-shelf ICs to save space. Let's see if I can get it up by Saturday or not. But no painting la.

Whoooo! So, if I fart, I can now control its direction!
