Introduction
Northstar Show Systems is a distributed show control platform for immersive entertainment venues. It replaces hand-wired show racks and laptop-based playback with a coordinated mesh of small Wi-Fi nodes governed by a central Intel NUC running HelmOS.
Components
| Component | Role | Hardware |
|---|---|---|
| Compose | Offline show designer | Windows or macOS desktop |
| HelmOS | Venue runtime | Intel NUC or equivalent x64 PC running Windows |
| Cuemaster | Operator dashboard | Any browser-capable device on the venue LAN |
| Polaris Node | Field actuator | Arduino UNO R4 WiFi |
| Polaris Bridge | Physical operator panel | Arduino UNO R4 WiFi with buttons and key switch |
Key Features
- Block-based show programming — Scratch-style hat, stack, and control blocks
- Distributed runtime — show logic centralised in HelmOS, field I/O on Polaris nodes
- Air-gapped operation — no internet required at the venue
- Wi-Fi firmware updates — boards flashed once via USB, then over-the-air for the life of the install
- Maintenance HMI — rollercoaster-style diagnostics with interlock chain, actuator test, and live I/O
- Physical-key authority — a key switch on the Bridge panel is the sole normal-flow route to Maintenance Mode
- Per-device licensing — perpetual, Ed25519-signed tokens bound to the machine fingerprint
Target Applications
- Haunted house attractions
- Escape rooms and puzzle venues
- Themed entertainment dark rides
- Live theatrical productions with environmental triggers
- Museum interactive exhibits
- Immersive art installations
Design Philosophy
Northstar is built for reliability over flexibility. The system makes deliberate trade-offs: a fixed hardware platform (UNO R4 WiFi) over arbitrary microcontroller support, a single network architecture (TrueNorth Wi-Fi) over general networking, and a constrained block language over open-ended scripting. The result is a platform that show operators can run without engineers on site.
