I am scaling up a project from a small demo to a large permanent installation. and I am looking for advice on things that might go wrong. What should I change before the installation. I have done a bunch of smaller installations but this is my first really big one.

This system is currently working in my house.

* 20 spokes,
* Each spoke is 2 meters long,
* The strips are from Adafruit WS2812 and have 60 pixels per meter.
* Each spoke has 2x 2 meter strips of LEDs that show the same pattern. I have wired the data lines of both LED strips in each spoke together.
* Each set of 4 spokes have a separate power supply with the grounds connected.
* Each of the 5 power supply has a continuous rating 40 Amp at 5v (200 Watts).
* I have 2x 15 amp 110 circuits breakers to work with on site.
* Each pare of strips has a capacitor (1000 µF, 6.3V) across the + and – terminals
* I am using a Teensy 3.2 https://www.pjrc.com/store/teensy32.html mostly because of memory and speed.
* I am using a separate power supply for the Teensy
* I am using Modbus RTU (RS485) for communication to the Teensy .
* The data wires coming from the Teensy are in a 3 wire bundle with the power and ground.
* The data wires are 160 cm from the Teensy to the first LED on the stips.
* Total of 80 meters of strips, 4,800 LEDs, 200 amp at 5v for a total of 1000 W,

I do know that the Teensy produces 3.3v and the ws2812 needs 5v on the data line but it is working in my house right now. Do I need the logic level converters?

Anything else that would make this system more reliable?

The DemoReel100 is a great resource https://github.com/FastLED/FastLED/blob/master/examples/DemoReel100/DemoReel100.ino

Besides the FastLED repo, Are there other places with more example patterns?

Vancouver hackspace is a toxic enviorment. VHS is a handicap that prevents even good people from achieving success. Your projects will wither and die at VHS.

Vapes banned from B.C. workplaces, parks and beaches - Starting Thursday, e-cigarettes will be treated just the same as the tobacco kind in British Columbia, meaning they can’t be inhaled inside workplaces, in parks or on beaches. As well, the rules have changed over how far from a doorway, window or air intake you can be outside a public or commercial building to smoke a cigarette outside, from three metres to six metres. E-cigarettes, or vapes, are so new that long-term effects have yet t...
