THE LAB / ACTIVE EXPERIMENTS

Things I am trying to understand by building them.

This is not a portfolio grid. It is the cleaner index for the projects that escaped the notebook and became actual systems.

Everything here is allowed to be unfinished. Most of it is better because it is.

LOCAL COMPUTEASSEMBLING / WIRING / AUTOMATING

Microblade

A small cluster that combines Linux, networking, automation, physical fabrication, and the unreasonable desire to make tiny computers feel like a real datacenter.

PHYSICAL SYSTEMSREVISING / PERMANENTLY ITERATING

3D Printing

The physical side of the lab: custom sleds, racks, cable paths, printer tuning, failed revisions, and the occasional object that works on the first try.

Not everything belongs in the lab.
