RGB Bike POV
Nicely done RGB Bike POV! POV stands for Persistence of Vision, check out wikipedia definition
if you don’t know it yet.
The whole thing is based on a pic16f628A, with some SMD mosfets to power the led’s. Those are very bright RGB led’s with SMD resistors for smaller PCB size and lower weight. That’s important too when keeping in mind that a heavy weight could give a unbalanced wheel. When all the led’s are on ( 32 led’s, each 3 colors, it draws 10Watt, but normally it will use less than 1 watt. Power comes from 4 NiMh AA cells. And there lifetime before charging is very long.
Keeping the rotation synchronized with showing the text is possible by 2 reed sensors. So each rotation shows twice the image. You could do it once, but that means half the refresh rate.
