Hi everyone,

Some time ago I asked some questions about DC/DC converters for a project that I am making, so now I wanted to give you a small update about what we’re making.

So this picture shows our prototype: an interactive ‘tensegrity tripod’. The final installation will consist of 40 of these tripods, so a lot of work!

Whats inside: each tripod is controlled by one Teensy 3.2 communicating over Ethernet (WIZ820io). As you could have guessed, it uses the FastLED and OCTOWS2811 combo to control all 672 LEDs. Each tube also houses a MTCH105 chip for touch-sensing using 4 ‘antennas’.

All sensor input is communicated to a computer running Processing, which generates the light effect and sends it to another computer running Enttec LED Mapper.

I hope you like it, and I will make sure to post a video when it’s all up and running. If you are interested, you can follow us on our facebook: https://www.facebook.com/lumenusglow/

What did you end up doing for power?

@Robert_Atkins We use 10 12V Meanwell power supplies to go to each tube. From there, a Murata Power okl-t6-w12 converts the 12V input to 5V. We also have a small LDO on board to power the microchip (3,3V).

Exactly the setup I used for the OIJ project. Can you post a photo of the controller board in the tube?

Aha, the okl-t6-w12 have a much smaller footprint than the okl-t10s I used. Still, amazing parts.
