Workshop Log 003 — The Control Core Takes Shape

Mid-July 2026

Once the first ForceBox experiments worked, the question changed. We were no longer asking whether coordinated costume effects were possible; we were asking how to make the system compact, dependable, and practical enough to wear.

The Nano R4 became the control core for the current prototype generation. Its small footprint lets the controller disappear inside an enclosure while still giving ForceBox enough flexibility to manage six programmable output channels, three control inputs, synchronized sequences, and future audio or display expansion.

The important decision was not simply choosing a smaller board. It was defining a consistent system around it. Each output needed to be programmable rather than locked to one effect. Each input needed to support more than a simple on-and-off response. Accessories needed to connect in a way that could be serviced, swapped, and reused.

That architecture gives a builder room to create very different behaviors from the same hardware: status lights that breathe or pulse, an arming sequence that advances through several colors, radio effects that combine light and sound, or a prop mechanism that activates as part of a larger scene.

This stage established the brain of FDP-002, our first integrated development prototype. The next milestone was giving that brain a voice.
