Have you ever wanted to take HDMI video and output it as art or display it on devices that are not normally HDMI compatible? If so, Pixel Wrangler from Trammell Hudson is for you.
The Pixel Wrangler is a tool for converting HDMI video into anything else. It uses an ice40up5k FPGA to decode the video stream and stores a section of it in the block RAM, which can then be clocked out of the 16 GPIO pins in any other format required.
Since the FPGA has total flexibility in how it drives the output pins it is easily adaptable to different protocols. Some examples that are possible:
- Classic CRT monitors like B&W Mac or Hercules monitors
- LED matrices
- Flip dots
- LED strips (ws2812 or other protocols)
- Lots of servos for “wooden mirrors”
Check out some of the uses on Mastodon and see more about the project on GitHub.
