How to stop the flicker of the image

Post by el337 » Tue Jan 31, 2012 3:33 am

Hi Brad,

My POV display is working well but I get a flicker of ~16Hz of the image or text as is moves.

Do this mean I need a faster motor, or can I change the LED on/off times to get rid of the flicker.

Thanks

Sorry for the late reply.

Basically to stop the flicker - the motor has to be rotating such that it updates the image at at least approx 25 times per second.

It can be a little hard to do this because it gets a little unstable at higher speeds.
