Drawing images

Post by HobbyMan » Thu May 03, 2018 1:27 pm

Hey,
This has been on my mind for a little while now. I think it would be cool if you could use a TX-capable SDR to draw images in a waterfall display. You could scan the image bottom-to-top and modulate the frequency based on how dark/light the pixels are. Just an interesting thought I had. I barely have any experience with SDR (or radio in general), so it’s unlikley that I would be the person who does this :lol: .

Look up gr-paint https://github.com/drmpeg/gr-paint. It's been tested with the HackRF before.

Also see Spectrum Painter https://www.rtl-sdr.com/painting-on-the ... -a-hackrf/
