Information centre Amsterdam North/South subway
| Summary | Programmable full-colour LED indicators showing the route and current status of the metro line being constructed in Amsterdam, The Netherlands |
| Customer | Podium |
| Time | 2 months |
| Components | 427 LED controllers (model "Twinkler") with light pipes, solid-state PC (running Linux). |
| Description | The 427 Twinklers (LED controllers) are connected through a single serial bus. Every Twinkler has a low-power RGB LED with a controller and a power regulator. Each Twinkler on the serial bus can be individually addressed. A solid-state PC allows interactive updating. Light pipes transport the LED colour through a 36mm thick table top. |
The colour and brightness of every LED can be adjusted individually, and dynamically
