GVS1b 1.5 bit video sampler from Gijs on Vimeo.
[gijs] sent in an Arduino video sampler he’s been working on. The sampler is able to capture, pause and play a short video forwards and backwards.
The video capture circuit is based on the Nootropic Design video experimenter. We’ve seen a few project use this video experimenter board, but never with such smooth video. The sampler samples frames at a resolution of 128×96 and stores everything in a 256Kbit SRAM. A back-of-the-envelope calculation tells us that the sampler can hold a little under a second of video, more than enough to do something cool.
[gijs] says there is a 1 bit version and a 1.5 bit version of his video sampler. While we’re busy wrapping our minds around what half a bit is, he’ll be upgrading the 1.5 bit version to 2 bits. He’s also ordered some PCBs and expects to have a kit out by October. Check out a demo after the break.
