Only use jellyfin. Have a list of things want to update… but it works for now.
Yes that is a laptop usb cooler used as supplemental placebo cooling. Also a pc fan I have propped up against the hard drive feeding into the pi.
Can’t recall last time used the ps4 or switch. But they’re there
Seven Raspberry Pi 4’s and one Pi Zero, mounted on some tile “shelves” inside some IKEA furniture.
What do you do on that many pi’s that could not be done easier on 1 x86 box?
They’re fanless and low-power, which was the primary draw to going this route. I run a Kubernetes cluster on them, including a few personal websites (Nginx+Python+Django), PostgreSQL, Sonarr, Calibre, SSH (occasionally) and every once in a while, an OpenArena server :-)
I did a 4 node Pi4 kubernetes cluster for about 5 years. The learning experience was priceless. I think most notable was learning to do proper multiarch container builds to support arm and x86_64. That being said, about half a year ago I decided to try condensing it all into two n100 nuc-like clones and keep one pi as the controller. For me and my apps and use cases there was no going back. Performance gains were substantial and in this regard I think I was hobbling myself after the educational aspect plateaued.
My 12u setup On top I have two pi’s; home assistant and pihole The ONT for fiber, hue bridge, and hdhomerun.

Ok, now this is just showing off. Patch cables all the exact required length and everything all nice and neat. I bet you check your backups regularly and do a monthly DR fail over test too.
…Kidding aside, your setup looks really good.
Haha I need more Patch cables to get rid of those long ones. Also when I opened up the cabinet for this Pic I noticed the left fan isn’t dusty like the rest so it might be dead x_x
My little cluster
An old HP laptop with Debian hosting Klipper and Home Assistant. Waiting for an OTG cable so I could replace the laptop with a phone for less power and heat
Using phones with a continuous power supply might do nasty things to the battery.
Source: I finally figured out how to open a glass back phone with no tools.
Heat, then suction?
On a related note, I solved the battery issue with my wall mounted Fire tablet (for an HA dashboard) by connecting the power supply to a smart plug and setting up an automation to only give it the juice for about 3 hours per day, spread throughout the day
It still amazes me that the smartest phones aren’t yet smart enough to have direct power supply.
Like my 40 year old AM radio.
I’ve done similar with an old Android tablet. Installed Fully Kiosk Browser to display the dashboard AND read the battery level - above 75%, switch off power…
But… automations only trigger when going past the threshold once, so if there’s a random issue where HA doesn’t see the battery drop below 10%, (had that happen a few times in the past), then I also have multiple triggers for 5% and 2%… to turn the power back on again 😉
Wait I see EMT piping for that printer frame… Did you convert an Anet A8 to an “EMT-8” like I did!? :D
Just seemed like a neat coincidence!
The stock A8 was such a scary fire hazard lol.
Yup you’re indeed seeing an EMT8 :D. This thing’s got a SKR mini e3 V3, E3D v6 clone and an E3D titan clone. I have a post about it in my profile.
I bet there are dozens of us EMT8 owners! Dozens!
That’s so cool! Nice work! I feel a certain kinship with anyone who also got tons of 3D printing XP by building, rebuilding, researching, modding, head-scratching, laughing, crying, screaming at an A8 lol.
This here is mostly fire prevention: Basically an updated stock motherboard, better PSU, an aftermarket MOSFET board for safety, thicker gauge wires with ferrule crimps for all the power cables, the bed is now attached directly to the thicker wires by way of crimp connectors.
The printing surface is upgraded to carefully cut and polished picture frame float glass. 😂
Added that sweet fan duct mod, a little Noctua 15mm (because it softened and jammed otherwise LOL), and printed that purple bracket at the library because the plastic decided to literally crumble away.
Also the adjustable Z-stop was nice but the PLA softened so it’s a bit unpredictable, and the right motor will gently slip until it’s engaged so the gantry needs to be leveled every time…I also can’t guarantee that the Z rods are straight anymore because it requires such a Goldilocks level of tension I probably overdid it lol.
Oh yeah, I had to replace the main power cable because the one provided just…had a break in it.
It still works for small jobs though! And it printed all those parts for itself, so that’s kinda the RepRap dream right there right??
Lol I feel like an amazing machine is in here somewhere if I bothered to research custom boards and stuff. The stock bearings are also terrible. But if I can bother someday I’ll stick Klipper on it maybe.
It was a crazy, stressful journey…but I learned a ton of electronics stuff, and how to use a multimeter, and engineering stuff! XD
My Ender3V2’s felt like such a crazy luxury by comparison. 😂
Could I interest you in some diagonal bracing today?
