The premise

Use what you have

Old office PCs, thin clients and a MacBook can be more useful than another impulse purchase.

Measure the trade-offs

Purchase price, idle power, noise, maintenance and what happens when it fails.

One or two real services

Home Assistant, an NVR, a backup target or a research agent — not 40 containers for the sake of it.

Keep it reversible

Backups, simple rollbacks and a clear boundary between home infrastructure and a VPS.

Latest field notes

Small computer on a desk

What can you do with a $100 thin client?

The Dell Wyse J5005: enough for Home Assistant, MQTT and network tools, but not a magic local AI box.

Network equipment

VLANs without ruining your weekend

A cautious, staged approach to network segmentation when the house still needs to work tomorrow morning.

Security camera view

Building a camera NVR from an old Dell

Why an i5-11500T, 16 GB of RAM and a couple of drives make a better appliance than another cloud subscription.

Cloud server concept

Home server or VPS?

Put public, boring and always-on services where they are easiest to keep alive. Keep private experiments closer to home.

Research notes

A second Hermes agent on VPS #2

Using a small ARM VPS and Crawl4AI for a private research and paper-trading experiment.

Power and hardware notes

The equipment decision log

What I bought, what I already owned, what I nearly bought, and why “good enough” is often the right answer.
