Been playing with a Raspberry Pi Zero clone (Orange Pi Zero 2W) to make a portable travel router + app server + party box + development environment. Basically seeing what all I can cram into four 1.5 GHz cores and 4 GB of RAM in a Pi Zero form factor.
Its primary upstream is wifi (but can use ethernet or USB tethering with some reconfiguring) and also presents an access point. AP, ethernet, and USB ethernet gadget interfaces are bridged into the "LAN" segment.
Has multiple VPNs (one for privacy and one for connecting to my internal stack), PiHole for DHCP services and ad blocking, PairDrop for sharing files, CodeServer for development, MPD and Snapcast for listening to music (plus another Pi Zero to act as a satellite speaker), Kiwix with the full 120 GB dump of Wikipedia and pretty much every dev doc I could load, Calibre Web with most of my book collection loaded, and Searx-NG to provide a portable search engine that's not infested with AI and SEO slop.
It's also running Nginx with real Let's Encrypt certs so all the web apps it hosts are properly running behind HTTPS.
Still working out some kinks / hardware quirks and don't have the scripting automation complete to cast from Bluetooth to Snapcast server, but that does work on the bench.
I call it the "Quirky Turkey".
