Mechanical Colour Television Using Arduino Due

This is a mechanical colour television that I built using the Arduino Due. It uses a 32 hole disk, so there are 32 lines of vertical resolution. Horizontally, there are 96 pixels in each line, though the effective resolution is limited by the hole size. Video and audio data are read from a micro SD card using the hardware SPI bus. 24-bit true colour is produced using three 8-bit DACs communicating over a separate bit-banged SPI bus. Mono audio output is produced using one of the two 12-bit DACs included on the Arduino Due. Additional circuitry is implemented on the main board for controlling the LED currents and for audio amplification. A software PID loop is used for motor control allowing the frame rate to precisely match that of the camera.

Thanks for sharing! I always found the concept of mechanical television interesting.

Awesome; very cool project. Thanks for sharing :)

Great design! More steadier than other designs including my own. I design and build a unit with standard components, so no Arduino. Nevertheless, most interested in the sketch and do you use analogue outputs from the Arduino??? And how did you make the disk. The holes are so needly

sir can provide the procedure and coding of this project please..

[MOVBIOS]

hellow can you provided schematics?, or files? please!!

Neato. Can it scale up to 100 ft tall? Can it look more steampunk? Where is the video of it being made - people love to watch that stuff.
