I just use the webapp UI and don’t bother with the clients/extensions. Easy enough to just log in, copy/paste from there.

But yeah, the official client (and probably browser extension as well) would probably be forked if/when needed.

I use Vaultwarden

Thanks, and yeah, it’s been fun putting that all together. Unfortunately I’m still learning FreeCAD so they’re not as integrated as I’d like yet, but as soon as I have time to hammer out a design, I hope to have all 3 of these and the UPS/power supply in a nice case.

Yep, running/charging it from solar is why I ended up getting that chonky 18650-based UPS board. It’s the only one I could find that could combine 5V input and battery without dropping out (battery kicks in immediately if solar insufficient and draws the difference between input and output and charges and powers simultaneously otherwise).

Thanks!

What are the use cases for taking it with you instead of just connecting to your homelab?

I built it just to see how much I could cram onto a Pi Zero clone/how many self-hosted services I could have on something I can fit on my keychain, and the answer was “a lot”. It’s something of a travel server, travel router, emergency backup server, etc.

I mainly just wanted a subset of my homelab services available in something I could take with me anywhere. Home lab could go down while away, power could go out, something to use while glamping, can take it with me if there’s ever an emergency where I have to evacuate, etc.

What started out as a single unit has become a three unit portable stack lol. Yay feature creep!

Services

• Jellyfin (all content pre-transcoded so everything can direct stream)
• CodeServer (setup for Python, NodeJS/Bun + React, and Platform.IO for ESP8266/ESP32 development)
• Kiwix (including the full Wikipedia dump with images as well as offline docs for lots of code libraries I work with, etc)
• SearxNG so I always have a sane search engine available
• CalibreWeb with my whole ebook library
• MPD+Snapcast+My whole music library. Also has myMPD web UI for controlling MPD. Snapcast clients can connect, and it can serve multi-speaker/multi-room audio
• PiHole serving both ad blocking and local DNS as well as providing DHCP for the access point
• PairDrop for sending/receiving files
• NodeRED and Mosquitto MQTT for setting up ad-hoc automations
• Nginx with real LetsEncrypt certs so all services have valid SSL certs and hostnames

Networking

• One USB port is configured in ethernet gadget mode. Can plug it into a host PC and get an IP address from it
• One wifi adapter is setup as an AP and is bridged with the USB ethernet (a PC plugged in and a wifi client are on the same L2 plane).
• The second wifi is the “WAN” connection if one is available. Can alternatively connect to USB tethering on my phone
• If there is any kind of “WAN” upstream, the LAN bridge (USB ethernet/Wifi) will route to it
• Wireguard to connect back to my homelab.

File Services

• Samba
• Encrypted LUKS volume for critical docs (tax records, vet records for the dogs, etc)

I’ve got a second unit that connects as a client to the main one with some additional backup services:

• Email stack( Dovecot, Postfix, SpamAssassin, ClamAV, Webmail)
• Matrix/Synapse stack
• Asterisk
• Snapcast client

The second one is basically a backup to my main stack in case of disaster/power outage/etc. Those all tunnel to a cloud VPS + load balancer and only need an internet connection to setup the tunnels to receive traffic from the VPS (and route back out to it). Those services are stopped and a cron task keeps them in sync with the main ones in my homelab. If I need to fail over, I just SSH into the VPS and re-route traffic to them instead of my homelab endpoints.

I self-host my own email and chat and phone services, so those have become critical services I want to always have online. Essentially these little Pi clones are a backup stack for my most used services and one that is both extremely low power and portable should I ever need to host them on the go (house burns down, have to evacuate due to emergency, etc).

Third Unit (Still on the bench)

I have a third unit that’s built on a PiZero2W but it’s still on the workbench (but functional!). Just haven’t gotten any kind of case at all built for it.

It’s got two RTL-SDR units attached. One is tuned to the NOAA weather radio station and feeds into Snapserver on the main unit (so you can listen to the weather radio anywhere on the network) as well as piped into Meshtastic EAS-SANE alerter in order to forward emergency alerts to Meshtastic. There’s a USB-connected Meshtastic node attached as well for that.

The second RTL-SDR is setup as a generic FM radio tuned to the local variety station. It’s just piped to Snapserver on the main unit to make it available on the network.

I may convert the second SDR into a ADS-B listener, but for now, I like having the FM radio available.

I run Jellyfin on a Banana Pi M4 Zero. It’s a little less capable than the Pi4 but runs JF just fine. Specs on this one are quad core 1.5 GHz, 4 GB RAM, 32 GB eMMC on Armbian.

The media files are all on the 1 TB SD card while the Jellyfin data directory (especially the SQLite DB) are on the eMMC. This seems to work much better as the DB file kept getting corrupted on SD. Should also help the SD card from wearing out since it’s pretty much only reading data from it most of the time.

As you guessed, transcoding is not going to work (JF is removing the v4l2 hardware support anyway), so I pre-transcode them to H264 + yuv420p in an mp4 container before moving them to the SD card. I also scale them down to 720p to fit more on there, but that’s because this is a travel server and isn’t my main media source.

Can’t speak for Paperless though.

GLaDOS/GabeN: They’re sentient, you know. I think that one was about to say “I love you”.

AI mixed with news sourced from X. What could possibly go wrong?

Yeah, hard pass from me.

I like the concept because it’s reminiscent of the early computers I grew up with (Tandy CoCo, Commodore 64) and I basically just dock my laptop with its lid closed anyway (screen is too small and resolution too high for my old person eyes).

But considering it’s literally a keyboard PC, you’d think they’d have put more effort into making it a nice keyboard. I hate those “chiclet” low travel keys. Put a PC in a good mechanical keyboard or at least a membrane keyboard where the keys have some travel, then we’ll talk. Until then, it’d be a tad ridiculous to plug a good keyboard into my keyboard PC lol.

It’s not much cheaper than an equivalent laptop, so who’s this for, exactly?

I guess if there were an LCD shortage instead of memory and SSD, it would have a lot more potential.

If I was going to fall off the wagon after 2 years, I hope to gods it would be with something better than Bud Light.

Mine’s only for people I know personally, so it’s backed by my LDAP server and registration is disabled in Synapse. I use my regular onboarding process to create the new LDAP user and grant access to Synapse.

I just want more games to let you quit to desktop from the game without having to first “Quit to main menu -> Are you sure? (yes!) -> Loading screen + main menu animation -> Quit to Desktop -> Are you sure? (Yes, i’m goddamned sure!)”

Here’s a write-up I read not too long ago and answers many of your questions, though the author is mostly concerned with getting data access going. Short answer is yes, most will “just work” provided you use the correct modes and configs.

do linux apps working as contact list/dialer/SMS receiver/sender exist?

Those all fall under what’s called the IMS (IP Multimedia Subsystem) and is often problematic implementing in open source. If I recall, Ubuntu Touch has a (mostly?) working IMS implementation but I don’t recall if it’s universally functional or limited to specific devices/carriers. Some WWAN cards will allow calls/texts, but those are usually in “3G” mode which is rapidly disappearing as carriers switch to VoLTE or VoNR/Vo5G (which are basically just fancy VoIP).

If you’re willing to forego traditional carrier voice/messaging, you can use any number of messaging apps that work on Linux and/or combine that with a 3rd party VoIP provider for PSTN calling/phone number and SMS/MMS. Just don’t expect to get RCS messaging going; even on Android proper, you’re limited to Google Messages only.

If you’re going to post political memes in a non-political meme community, at least spell things correctly.

Nice! Those AllWinner boards are a little tricky to get going and have some quirks, but the price is great for the extra horsepower you get. Granted, I use the latest Armbian since the manufacturer’s images are all quite old.

130GB for the entire thing? And the pi doesn’t choke on indexing / searching it?

That was my thought. I knew it couldn’t hold it in RAM but thought it would be doing crazy IO and limited by being on SD, but it seems to not be a problem. Like I said, I don’t know how ZIM does it, but it does it well. Must have some kind of index that lets it fast travel to the correct blocks or something. I dunno lol.

how capable is the search engine (I assume it has one?)

Yep, it has search. It’s…okay but kind of primitive. It’s not slow, and if you’re searching for something that’s fairly unique (as far as keywords go), it does well. But if you’re searching something like an acronym where it shows up as a regular word in other entries, it’s a lot more hit or miss.

Yep, and I love it.

I’ve got a little Banana Pi M4 Zero (PiZero form factor but much more powerful and with 4 GB RAM) loaded up with, among other useful tools, Kiwix and the full Wikipedia dump. I just refreshed it with the 2026-02 full dump, so I’m caught up for the year. I’ve also got a lot of other offline docs loaded up (React, Bun, and the devdocs for several libraries I use) and it’s nice to have local copies of those instead of googling every time.

Surprisingly, the full ~130 GB Wikipedia dump works fine on a regular Pi Zero 2 with 512 MB RAM. I don’t know how ZIM works but it does work very very well.

Yeah, that’s what I’ve got, and I really like it.

I’m in the same boat. Got all the equipment in for my whole house solar installation and will be re-routing circuits to the new panel as soon as I have time so will have to turn all the power off for the duration of that.

I’ve got an Anker power station that should run my stack for about 4-4.5 hours by itself and can run it indefinitely while the sun is out while hooked into the PV panels. Those are (currently) independent from the new installation I’m about to start.

My UPS’s are also LiFePO4 models and can add an additional ~45 minutes of uptime. So hopefully 5 hours is enough to avoid having to shut anything down.

If anything, I understand less.

Ugh. Prob similar to the posters who are well aware political meme communities exist but insist on posting them here. There’s nothing temporary about those blocks, but I’m willing to let the horny posters get it out of their system and unblock them later.
