I’m beautiful and tough like a diamond…or beef jerky in a ball gown.
I feel that.
Before I downsized, I was running 3x HP DL360 G6’s with dual Xenons and 96 GB RAM each. Way overkill for my needs but I got them cheap. Unfortunately, they and my air conditioner competed to see who could use the most electricity each month. 😆
The only thing I really lost in the scale down was the ability to spin up dev/test VMs for every little purpose. I’ve mostly just started using Docker containers for things like build environments.
Their Intel graphics work great for transcoding, but yeah, not much else. I’ve got Emby one one of them, and the QuickSync hardware acceleration works well even with multiple simultaneous streams.
Works pretty great as long as you keep your expectations realistic. Easy to upgrade and pretty reliable. Only annoying thing with any of those micro PCs is the cable management is a pain because of the power bricks. I got some USB-C PD adapters and Dell-style cables and that’s made a huge improvement.
About 220W on average with peaks around 280W. I’ve got 8 Optiplex micro PCs, 5 upcycled thin clients running smaller services, fiber ONT, another micro Optiplex as a router, a storage server, main switch, and a 5 port PoE switch for my 4 access points around the house.
Before I downsized everything to the USFF PCs, I was running 3 old enterprise rack servers that were about 220W each.
It’s currently running from solar from about 7am to 4pm with my small solar setup, but I’m in the process of installing a whole house PV system so hopefully will be 24/7 solar powered soon-ish.
Either (voluntarily) 50 years after Earth has been rendered uninhabitable by the upper class who has since moved to Mars or (involuntary) 50 years before that.
I’ve been told that government auctions canbe a good source for cheap used PCs
Can confirm government surplus auctions or sales are a great source for cheap PCs and that they do get snatched up quickly (guilty!) The only other catch is they never come with hard or solid state drives. I’m assuming those just get pulled and destroyed.
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.
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!
I’ve got a second unit that connects as a client to the main one with some additional backup services:
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).
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 still don’t have a “full” case for it, but here is the core unit attached to a UPS circuit which gives it up to about 14 hours of runtime. I’m also planning to add a small USB hub with ethernet into that, but I’m still learning FreeCAD so I’m not quite ready to put it all together yet. The USB power cord is wrapped in aluminum foil and electrical tape due to RF from the Wifi adapter causing random glitches. I need to add some ferrite beads and route them away from that when I build it into an integrated case. For now it looks janky but works lol.
Main Unit:
Secondary Unit: This is an older photo and is also connected to my Bose radio acting as a Snapcast client to the server on the main unit.
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.
I am a hillbilly occasionally cosplaying as a smart and educated person
Same. Which explains why I (twice, lol) incorrectly used the terms “theory” and “hypothesis” interchangeably when those are totally different things in sciences.
I’m not entirely 100% dark matter exists in galaxies the way often described. … The way I see it, it might as well be a repulsive force between galaxies opposed to the current understanding of it being am attractive force. Plus, if it were a phenomenon that pushed things apart, it could also explain Dark Energy.
And to me, that’s a perfectly valid theory. Like other proposed explanations for dark matter or dark energy or “whatever the hell it is we can detect the effect of but can’t identify”, it’s difficult to test.
That’s why I enjoy science. It’s like a big puzzle, and sometimes you get halfway done and realize you put it together wrong and have to start over.
The thing with dark matter is it’s just a placeholder term for “we don’t know what the hell it is”, and aren’t most hypotheses pulled out of the ass before experimentation to prove them?
Plus, Dr. Kaku is a string theorist so wacky is pretty much par for the course in that field. Granted, I consider him more of a TV personality these days and grew up watching him as a speaker on [insert any number of Discovery Channel shows here].
Maybe I’m just biased and enjoy the wacky theories because I’m more interested in seeing them proven right or wrong and thinking about the implications if they happen to prove correct.
GLaDOS/GabeN: They’re sentient, you know. I think that one was about to say “I love you”.
[Tina] Fey / [Robert] Carlock
They’re the team behind “30 Rock”, “Unbreakable Kimmy Schmidt” and several others.
Also Jack Burditt who produced both of those and many other shows I’ve enjoyed such as “Just Shoot Me” and “Frasier”.
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.
In theory you might be able to pass yourself off as some kind of supernatural figure, but not without knowing anything about their belief system first.
so it’s 30% not 20%
Fair. I was going by population numbers vs votes cast and didn’t have the voter turnout numbers handy when I originally wrote that out and was paraphrasing from that to save time.
But that’s still far from half, and I’m tired of people using the misconception/phrase to justify their xenophobic rhetoric.
Ugh, yeah. My “temporary” spinners that were an emergency upgrade became permanent when I went to buy the new ones and prices had skyrocketed. I’ve got one cold spare left, so hopefully there’s a price break in the near-ish future
