Crystal Signal Pi
This video is about a Raspberry pi HAT and custom case combination which allows you to turn your Raspberry Pi into a notifier device. I was one of the programmer/circuit designers on this project. We sell it in Japan.
Some Background information about the project:
It all started with keiko-chan. I work in a company with some servers and the need to keep up with errors or any kind of emergency situations that might occur on said servers. And a product called keiko-chan was used to broadcast these server conditions to all the people concerned. keiko-chan works great. But there's one problem; The price tag. It is only after you pay $500 that you are able to enjoy the merits of server status broadcasting with rotating lights.
The thought of building a LAN alarm light system with a Raspberry Pi was rather quick to come. So we went for it and built the first prototype, then a new prototype and at last a SMD version. This video shows the notify functionality of the SMD version. Well, actually it just shows some blinking patterns. Here's some more info on the Raspberry Pi notifier HAT:
