Hi all,
I am finally starting a new project in about 3-4 weeks for our conference (and hopefully something that will last a few years) using approx 1,600of these https://www.aliexpress.com/item/200...809327580.html?spm=2114.40010208.4.145.RIoMnI with the ws2811 ic although from a different supplier (just an easy link to find). From the centre of the led, they will be separated 5.5cm vertically and horizontally and span roughly 4.4m x 1.1 meters. I will use a Teensy 3.2, an OctoWS2811 adaptor and I'll be using the Processing movie2serial software for live stream. I will mount them on a 2.7mm aluminium sheet for cooling and use PC psus for the 12v supply (pulling approx. 110 amps max).
The one main question I have (apologies if it's a bit novice of me) but I notice in the tutorial that the ground on the start and end of LED run goes back to the second side of the twisted pair to the octo adapter. Will it matter that I am feeding the LEDs with 12v? Will that kill the Octo adapter or is my understanding totally off the money?
Also, will it matter if I have them linked in rows of 3 for the first 4 outs on the octo and then rows of 2 for the next 4 to equal my 8 rows or is my understanding totally off again? Or would I do 6 row of 3 and 1 row of 2 and totally forget the last run on the cat6 coming from the octo?
Other then that, does any have any pointers before I get started?
Would anyone like updates on how it goes once complete? Let me know either way as this is new territory for me!...
Thanks in advance!
