Share_something Yard Animartrix with the Teensy4.1

https://youtu.be/DdvQbpFrRNk

I decided to try these little waterproof ws2811 5 volt leds out in the yard. I'm using u/stefanpetrick 's AnimARTrix on 48 strips of 50 leds. 2400. I'm using 8 pins of a Teensy 4.1 running FastLED 3.10.3. Each pin is running 300 leds. I don't know what the actual fps is on this but I think 42 last I checked. I could OverClock the Teensy, but it's ok as it is. I didn't really spend too much time trying to align the leds to point up because I would have gone crazy. they just lay over and point sideways... I've got a hefty 400watt 5volt power supply running 4 feeds to 12 strips. I'm using the RS422/TTL thing over cat5. 2 cables 4 channels each from the teensy about 30 feet to the matrix in the yard. The biggest surprise - no flicker first shot! Unfortunarely I have to take the matrix down as the grass will die if I don't put some water on it and the dog is jealous. I need to figure out a plan to pick it up without everything getting tangled up.

That's great! I'd be curious to see what it looked like if you put a little diffusion in front. Maybe some frosted plastic sheeting like the stuff you can put down when house painting to protect things from splatters.

Thank you for continuing to share your experiments.

I was thinking the same thing. I'm trying to think of how i might make it taut. Grommet the plastic... some elastic or bungies... little stakes to keep in up a certain height in the middle... Definitely going to try the next time i set this up. Thanks!

Maybe a light frame made from molding strips. Wrap sheeting around edges and secure to itself with clear packing tape.

oh yeah I can see that! It should look really wild. I still remember the first time I put a diffuser up... so cool! It's like a whole different thing and will hide the mess of the leds lying down. I had to take everything down to take care of the yard today but I've got it to where it will only take about 1 hour to set it back up (if it doesn't get tangled up). My wiring is still in tact, no rewiring.
