Pi Day 2018
I have a bunch of RaspberryPi devices kicking around the house and office. There are some Pi 2s, Pi 3s, and a Pi Zero. I use them for a lot of different things. I just setup a Pi 3 to act as a scanning server for the Fujitsu iX500 ScanSnap that we use to keep a paperless home. There's a Pi 2 running NUT, some cron scripts, and some other admin stuff for my home network. We got a Pi Zero from an Ada Box that we setup to run RetroPie. While interesting, it's not overly complicated stuff. Places like Los Alamos National Labratory use Raspberry Pis for prototyping their large systems.
