hi stranger, the hardware.

When the AI leaves the screen.

A device I designed that makes my phone calls, my first robot, and software for a medical device. Drawn the way I think about them: in parts.

I always wanted a Pokédex. When Meta open-sourced Muse Gadgets, I designed my own device around it: custom hardware, an e-paper screen and a rotary encoder that drives an AI agent.

It calls on my behalf in German, using what I learned building real-time AI. It waits on hold, says it’s an AI and books the table. So far it has also filled in a refund form and booked water-heater maintenance.

I made its brand, its website and its launch film.

Two years into building with AI, I wanted to try hardware.

What it taught meOur avatars can run on the edge.

Closer to the real thing.
