At Naivi, the company at which I’m currently lead-developer, we wrote the software that animates, controls and pre-visualizes thousands of LEDs at 1000hz, using a custom designed effect DSP processing chain & UDP communication protocol.
The application is written using NAP Framework (Open Source) and runs autonomously on an Intel NUC with Linux and the Liquorix Kernel, which offers high precision timing guarantees to minimize jitter. The result is a unique, very smooth, viewing experience.
The performance was such a success, that the ring continued to appear at the VMA’s and Awakenings ADE. Here’s a peek behind the scenes.
Our software engineer Lesley van Hoek wrote a great blog post about the technology behind the light-ring.
