Let's Build a Video Card
I'm interested in learning more about VGA and HDMI, because I'd like to build a hardware freeze button.On an old church projector, there was a button on the remote so I could freeze the screen. Then I could switch from PowerPoint to QuickTime Player (or whatever else) without disturbing everybody who was watching. Newer equipment (some projectors, most TVs) lack this feature. I'd like to build a box that stores the current frame in RAM, and has a simple toggle switch between the stored frame or the live video feed.After a recommendation for the NeTV, I asked bunnie, and he said that the NeTV2 is a good choice for HDMI. It's pretty expensive though, and doesn't support HDCP.https://github.com/AlphamaxMedia/netv2-ideas/issues/21If anybody else has some guidance about how to proceed with this project, or some mutual interest that could translate into nagging me to actually do it, please get in touch!
