The HK9912 Ghost Trap LED Bargraph Display is based on a PIC microcontroller and is designed as a lighting module for GhostBusters movie props.
The display operates with a pre-programmed lighting sequence running in a continuous loop, creating an authentic visual effect.
Two different firmware versions are available, which can be seen in action in the demonstration video.
The module features a bright LED bargraph (red, yellow, green, or blue), mounted at an angle to fit properly inside a Ghost Trap enclosure. An additional red LED is included and flashes at a specific point in the sequence.
It is suitable for GhostBusters replicas, Proton Pack builds, Ghost Trap models, decorative displays, and collector projects.
