ChainFORM: A Linear Integrated Modular Hardware System for Shape Changing Interfaces
summary
Prototype is a chain of identical modules: a commercial servo wrapped by a flexible PCB with an ATmega328, capacitive touch on six faces and 8 Neopixel LEDs, connected via peer-to-peer links to a Teensy over I2C. Measured limits: about 170 kbps aggregated bandwidth, ~2 ms added latency per module, ~82 mA when motors run, and max 32 modules before voltage drop; servo torque is 0.8 kg·cm. System allows cutting and reconfiguring chains into sliders, styluses, small displays and attachable animated skeletons; hardware works but is an early, low‑resolution prototype.
