proof of concept for my most recent work. low life led is a scalable and weatherproof LED-toolkit.
arbitrary video content can be streamed via network to an array of microcontrollers, which in turn control the leds.
the leds are sealed in watertight acrylic tubes and attached with a simple, custom bus system. this allows for chaining without significant voltage drops.
in this demo the ability to calibrate the individual LED positions is showcased.
to make the setup quick and easy I built a calibration tool with the option to auto-calibrate with a camera.
the calibration sequence looks like this and created above results.
the software is based on my kinskiGL toolkit and can be found here:
