RGB LED controller

PixelBro84

A plug-in controller for the Hasbro 1984 Proton Pack that changes cyclotron colors and adds synchronized output for optional addressable cake LEDs.

Highlights

Color control without rebuilding the pack

PixelBro84 installs inline with the factory LED harness and stores its selected configuration for the next power-up.

Connects between the factory electronics PCB and the original four-pin cyclotron LED harness.

Cycle cyclotron colors from the device button and preserve the selected color across power cycles.

Provides a synchronized three-pin output for compatible addressable LED strings.

Browser configuration

Use the web configurator to set LED count, color order, direction, animation colors, offsets, and test patterns.

Use desktop Chrome or Edge and a data-capable USB-C cable.

Adjust cyclotron and cake LED behavior, then test individual positions before saving.
