Show control for themed entertainment

Mission-Critical Show Control,
Built to Just Work.

Northstar runs the lights, audio, video, pneumatics, and motion in haunted attractions, escape rooms, museums, and dark rides. One show file. One operator button. Sub-2-second trigger latency. Fully offline.

The platform

Eight Products. One Show File.

Every Northstar venue is built from the same building blocks. Hardware that talks to software that talks to hardware — all coordinated through a single nodes.json file authored once and run forever.

How it works

From Authoring to Air-Gapped Show in Four Steps

A Northstar deployment is the same shape at every venue. The same SSID, the same IP plan, the same file format. That sameness is what makes the system reliable.

1

Author

A show designer opens Compose on a laptop and builds the show — every node, channel, group, sequence, schedule. Mock-mode simulates the timeline offline.

2

Install

Field techs commission the venue: TrueNorth router, Helm PC, Bridge panel, Polaris nodes. Every install follows the same checklist.

3

Upload

The authored nodes.json uploads to HelmOS via Cuemaster. Schema validates. Hot reload — no service restart needed.

4

Run

Day-of operators press START on the Bridge. HelmOS executes the boot sequence, schedules fire on time, Cuemaster shows live telemetry.

Why Northstar

Built for the Reality of Themed Entertainment.

Venues are messy. Wi-Fi neighbors interfere. Drywall buries effects. Operators get hired Friday and run the show Saturday. The Internet drops at the worst moment.

Northstar is designed for all of that. The show network is air-gapped — no Internet means no Internet to fail. The frozen API means a show authored today still runs in five years. Every Bridge has a Server Reset button because shows must recover in seconds, not call-outs.

  • Air-gapped by default. No Internet dependency. Updates are sideloaded.
  • Sub-2-second latency. From operator button to first effect firing.
  • One file is the show. Version it, review it, restore it.
  • Frozen device API. Forward compatibility forever.
  • Field-replaceable. Hot-swap a Polaris in 10 minutes.
Use cases

Built for the Venues That Demand Reliability.

Haunted Attractions

Coordinate scares across rooms with frame-accurate timing. Schedule scare cycles. Bridge button on every shift.

Escape Rooms

Drive puzzle reveals, lighting cues, and audio stings from a single timeline. Reset with one button between groups.

Museums & Galleries

Exhibit shows run on a schedule, every day, every hour. HelmOS schedules cron-fire automatically — no daily babysitting.

Dark Rides

Per-vehicle timing windows, scene-by-scene effect sequences, and integration with motion control via the documented REST API.

Pre-Show Theaters

Audio bed, video plates, and lighting cues synchronized to the second. Loop-mode sequences for ambient pre-show timing.

Pop-Up Experiences

Pre-imaged kits ship from Orlando, deploy in a day. Air-gapped TrueNorth means venue Wi-Fi politics don't apply.
