I built a Raspberry Pi powered digital sign a few years ago and it ran for several years until multiple power failures smoked it. It ran a Google Presenter file from my Google drive for a good20 months or more. I was buying some Chinese electronic kits to learn how to solder and expand my electronics knowledge. On Banggood.com I found another small board computer-an Orange Pi Zero. I kind of worry about spending so much time looking at a website called “Banggood.com” at work. On my previous job this would have set off a lot of alarms. I have received the board but am still wrestling with getting it to work..
