Utter newbie, never ever, seeks consultant for LED project

by Suz665 on Sat Jun 13, 2020 3:49 pm

I’m so frustrated! I have a specific project I contracted to have made and the guy bailed on me. I call it the jellyfish. It stood 12-15’ tall, had strings of leds that shot fireball, twinkles, made patterns, and I would love to know where to start.
I have pictures but don’t know how to adjust to requirements here.
Sad, sad panda, please help!

To clarify: what exactly do you need done? Hardware? Software? Both? Is this your "jellyfish" or something you wish to replicate?

Hello and thank you! The guy that made this said he’d make me one. I saved up and now he won’t answer texts or emails.

Hi!

I recommend using "smart led" strips. They come with WS2812 leds or similar, which are super easy to use thanks to libraries. Also, nearly any micro-controller will be able to run these.

The slightly more challenging part is giving it enough power, there are good guides for that.

I think this is your perfect starting point:

Yes, NeoPixel strips are what you want. A feather M4 should have computing power enough to run the show with multiple lighting modes and such. I'd use a NeoPXL8 Featherwing to drive the strips https://www.adafruit.com/product/4537. A large 5v power supply will be required. 8 strips of 2m (60pixels/m) will need (at worst case: all on bright white) nearly 60A. Typical use should be far less. Multiple 10A supplies could be use (each powering several strips). https://www.adafruit.com/product/658

I've used similar hardware for a similar but smaller project.
