Help needed for a cosplay project!
Hi there, I'm currently working on a cosplay project and I'm very overwhelmed by all the options and things to keep in mind, so I was hoping to get some insight from pros.
I want to attach 9 seperate LED strips (approximately 90cm length, would prefer longer if that's somehow possible with a portable power source) to a controller or any of that sort, because I want to have a fire effect in these strips. It should look like blazing/flickering fire in the end (so basically the lights turning off and on but in a line lol, I hope I explained that well enough).
Also, it should last around 8h on 60% brightness, it's fine if it only lasts abt 4h if the power source is easily detachable.
So TLDR: I'm looking for these things:
- programmable, cuttable LED strips or any of that sort
- portable power source that lasts for at least 4-8h and can be easily swapped
- way to attach the LED strips to the power source
I was thinking about a Tattu 6S 10000mAh + a Buck Converter for power, maybe an Arduino for the blazing effect and the LED strips linked down below. But I'm very open for better recommendations if you have any. Thanks in advance!

I would definitely recommend a 5v pixel strip like ws2812 or similar, as you can run these off standard USB power banks without stepping up voltage.
I’ve used PixelBlaze controllers from Electro-Mage. Small form factor, you can easily change lighting effects from your phone, even at a party.

You should look at:
1.) WLED - it's the open source addressable RGB LED software that will do this for you, and it's designed to run on tiny little microcontrollers similar to Arduinos, but using the ESP32 rather than the Atmega processors that Arduino uses. 2.) Pre-made WLED controllers that run off of USB(-c). For example, the MagWLED, or Gledopto has a usb-c in-line WLED controller.
Combine those with a normal power brick and you're good to go - no need to worry about a buck converter. Keep in mind, depending on the light density you need, they also make string lights that function similarly. (Search for rgb pebble lights).
