I want something with the image/animation features of the spokePOV, and the 30 LED resolution is very attractive... but spinning in the air means no fork/downtube etc, so no hall effect for the hall sensor.
I'd imagine that using a simple 555 timer setup in the hall sensor's place to send a repeating signal that could be tweaked manually to keep the spokePOV setup cycling could do it, but it's been decades (86?) since I've played with digital circuits, so I'm not sure how to go about this.

however I cannot get the spokepov firmware to compile. I then tried with the unchanged original firmware and got the same result.
