I wanted to make a tiny fan that I could power with the computer's USB port, using one of the hundreds of motors I've collected over the years from tearing apart old optical drives for recycling.

This fan uses a FF-030PK motor that's very common in DVD drives.

The motor's voltage varies, depending on the model, but for what I could find online it's either 5.5v max or 7v max, and in both cases it can be used with the USB port (5v).

I measured the current used by the fan with the propeller on, and it was around 150ma, which is fine for any USB spec, I believe (500ma on 1.0 and 2.0).

The propeller is printed flat and you need to manually bend it to the correct angle.
