As a newbie to this, I got one of the olimex units with ready-to-go SD Card. I've had it for a couple of years, I think. I've tried various of the apps and have settled on using it as an always-on syncthing node and to run Privoxy on my home network.<p>To access away from home, it is running a Tor hidden service. Wireguard is also provided, so I'm thinking of trying that out as well. It snapshots, so if I get into trouble with a new app... I roll back. I keep all my syncthing data on an attached usb drive. I realize the SD card won't last indefinitely.<p>What makes it feasible for me is that installation, configuration, and backup is handled by its web interface. I haven't needed to edit config files.
