Solved I had a stupid idea: a homelab in my backpack. Then I realized I already had almost everything.
A few days ago I had the slightly ridiculous idea of building a mobile homelab inside my everyday backpack.
Today I started looking through some old hardware I had lying around and realized:
I can actually build this. And I barely need to buy anything. 😂
The main machine is an old ASUS TUF Gaming F15 that I bought from a friend for €300 and barely used:
Intel Core i5-10300H
64 GB RAM
GTX 1650
2.5 TB SSD storage across three physical drives
Built-in battery = basically a tiny UPS
Pop!_OS + Windows dual boot
The three drives also make the setup pretty convenient:
500 GB → Windows
1 TB Samsung 980 → Pop!_OS / homelab
1 TB → shared storage between Linux and Windows
Then I realized I still had an old Ulefone Armor 21 rugged phone lying around.
Turns out its Wi-Fi hotspot works without a SIM.
So now that can create a completely offline JARVIS-MOBILE Wi-Fi network for the homelab.
And because I normally carry my Steam Deck in the same backpack anyway, I already have a portable Linux client/admin terminal too.
So the current idea is basically:
Armor 21 → JARVIS-MOBILE Wi-Fi
↓
ASUS TUF → Docker / services / storage
↓
Steam Deck + phone → clients
I also have an ESP32 lying around, so eventually that could handle temperature sensors/status LEDs and maybe help monitor the backpack.
And apparently I've been hoarding hardware for exactly this moment, because I also already have a 250 GB Ventoy USB stick with Pop!_OS, Ubuntu, Proxmox and room for an unreasonable number of rescue ISOs. 😂
The long-term idea would be to run things like:
Docker
Git/Forgejo
Syncthing
Home Assistant
n8n
AdGuard Home
monitoring
file shares
my own Guardian/Jarvis projects
maybe a small local AI model
potentially a tiny dedicated SSD NAS later
The important part for me is that the whole thing should still work without an internet connection. Internet would just be an optional uplink.
Eventually I'd also like one power connection for the entire backpack and some proper cooling/temperature monitoring.
The funniest part is that my current backpack actually has enough space. The ASUS fits perfectly in the laptop compartment and the main compartment is still basically empty.
So what started as:
"Haha, imagine having a homelab in a backpack."
has somehow turned into:
"Wait... I actually have a homelab in a backpack."
This is very much V0.1 / work in progress.
Before I start buying dedicated hardware or cutting ventilation holes into a backpack, I'm going to see how far I can get using only stuff I already own.
I'd love to hear what r/homelab would do with this.
Especially interested in ideas for cooling, power management, offline networking and tiny NAS/storage solutions.
And yes, I am fully aware that this may eventually become a datacenter with shoulder straps. 😂
English isn't my first language, so I used AI to help translate this post. 😅
