I forget how I discovered HDEV, but now that I’ve found it, I can’t get enough! What can I say, I’m a space geek. HDEV stands for High Definition Earth Viewing. It’s an experiment to test the rate at which the image quality from an HD camera degrades over time while in space. And while it’s up there, they stream that video online for free. But you don’t have to be a NASA-nerd to appreciate HDEV. The views are truly incredible!
Which is why I came up with the idea for this project: a digital picture frame that live streams the video from HDEV, 24/7. I have a Raspberry Pi Zero laying around, it came free with the MagPi Vol 40 (which has an article about my previous project, my Magic Mirror). This sounds like the perfect project to put it to use.
HDMI 4 Pi: 5″ Display (no Touch) w/Mini Driver – 800×480 HDMI: Yes, this is a cute little 5″ TFT display with WVGA 800×480 resolution and a cute little driver board. We tried to get the smallest display that would be good for embedded computing usage and at a good price. And we also tried to match it with a small driver board that can be powered from a USB port. The visible display measures 5″ diagonal and is a ‘raw’ TTL display as is used in portable electronics. The driver board only has an HDMI input but for Raspberry Pi, BeagleBone Black and other computers, HDMI is the best quality output available. The display is very easy to use – simply connect the USB power cable to 5V power supply that can provide 500mA, then connect a digital video source to one of the HDMI port. Voila, a display!
