Challenge

In 2015, regular emergency shifts were replaced by computer-generated plans. I was looking for a new coding challenge (and did not want print-outs in my window displays), so I built my own system. It regularly queried the official API, mirrored it for offline use and displayed current emergency pharmacies.

I used an embedded ALIX board, an OEM E Ink display and a simple UPS. The system comprised several layers of redundancy and was immune to power blackouts of up to three days (with the option of running on batteries after that).

The system needed no service whatsoever and experienced no downtime in 4 ½ years!
