01who is andrew?
The seated mastermind
Andrew is a tech builder and hardware tinkerer from Australia who does his best thinking from a chair. He designs the bridges between humans, hardware, and the networks that carry them - from care-mesh architectures that quietly look after people, to edge compute squeezed onto Jetson boards, to the humble MQTT packets that keep the whole thing talking.
He likes making things useful, and he likes a good joke about a packet that refuses to behave. Both happen more often than you'd think.

Core processes
Seated mastermind
Thinks best from a chair. The plans are big; the legs are optional.
Systems thinker
Sees the whole loop, not just the node. If it connects, it counts.
Builder
Turns ideas into working things. Occasionally with solder involved.
Australian wit
Dry, self-deprecating, and delivered with a completely straight face.

Things on the bench
care-mesh
02Care-mesh
A mesh of small, watchful nodes that keep an eye on what matters - and tell someone the moment it stops behaving.

edge compute
03Jetson edge
Pushing compute to the edge, where the action is. Small boards, real models, and answers fast enough to be useful.

04MQTT tinkering
The quiet protocol that lets everything talk to everything. Lightweight, reliable, and endlessly hackable.

Telemetry panel
A live-ish readout from the bench. Values are demo telemetry, for the vibes - the only thing measured for real is the coffee.

05hobbies & bench notes
From the workbench
bench note 014
Soldered a thing
Soldered a thing. The thing now works. Nobody was more surprised than me.
bench note 013
Sensor with opinions
Taught a sensor to talk MQTT. It now has opinions about the weather.
bench note 012
Care nodes
Built a mesh of care nodes. They check on each other so humans don't have to.
bench note 011
Cable situation
More cables than is strictly necessary. The drawer is a metaphor.
bench note 010
Useful from useless
Made something useful out of something that was definitely not useful.
bench note 009
Negotiating with Jetson
Jetson said no. I said yes. We compromised.

Say hello
If you build things, or break things in interesting ways, or just want to talk about a packet that refused to behave - say hello. The handle you found this on is the fastest way to reach me.
