“I made a full color POV display using Raspberry Pi Pico and DotStar LED tape.
I made a full color POV (persistence of vision) display using Raspberry Pi Pico, wireless charging module and DotStar LED tape.
High-speed display is possible with PIO of Raspberry Pi Pico.
Constitution
LED tape, SPRESENSE and reflectance sensor are mounted on the rotating part, and LED tape uses DotStar. Using the wireless charging module, the power supply to the rotating part was carried out wirelessly.
POV Display Device
I used two Dotstar LED tapes controlled by hardwear SPIs (SPI0, SPI1).
Wireless charge module is used for power supply to the LED rotating part. It is only placed in the face-through the transmission coil to the rotation axis of the motor without almost processing.”
