Maker

The connected lab

Hardware and software that talk to each other.

The problem

Printer, PC and AI agents didn't talk to each other. To check a print I had to get up and go look.

My role

I chose the hardware and designed secure access. The code was written with TARS, with 44 tests as a safety net.

What I built

  • Agent deck. Who's working, who's waiting, in real time.
  • Connected printer. An old laptop runs it; progress and backups arrive on their own.
  • Studio climate. An ESP32 and an LED. In progress.

Agent deck

  • Coreworking
  • Codeworking
  • Copyneeds you
  • Elondone
  • Studyasleep
  • Managerworking

Simulation: fake states generated in the browser, not connected to anything.

The hard choices

  • Read-only access, local network only.
  • It has to keep working when the Wi-Fi drops.
  • Code and sprites written from scratch.

Stack

  • Node
  • Home Assistant
  • ESP32
  • 3D printing
  • 44 tests

Where it stands

Deck and printer work. The climate sensor is in progress.

What I learned

Look for the bottleneck, not the symptom.
