“I bought 2 of these and run both from a single Pi. They work brilliantly using the Adafruit software on github.
They were pretty easy to solder for someone who only picks up an iron once every 15 years. I even changed my mind about how best to wire them and managed to desolder and resolder the connections without any dramas.
I have a rather elaborate desk at home covered with lights and gauges running off 3 Pis and these were a nice finishing touch. I use one for work emails and weather alerts and one for personal emails. The backlight on these is extraordinarily bright so they also serve to illuminate my keyboard at night.
Friends have pointed out that they get email alerts on their phones already. Yes, but did they learn anything about soldering, wiring or programming? At this price it would be silly not to try.”
