Paint roller POV

Carlos sent us this interesting take on persistence of vision tech. This “low tech – POV spinning display” uses an arduino, paint roller, and the contact braids from a toy slot car. Clever design – those contacts act as an effective timer/trigger, simplifying the manual animation(aka – waving) process. – Link
