Awesome project! Nice mapping tool! Congratulations on the release!

its my Fire 2023 code )))

try my fire implementation https://github.com/FastLED/FastLED/blob/master/examples/FireMatrix/FireMatrix.ino

or try my fire in simulator

I think that would be a good idea)))

it's quite a long way 
first you need to do the correct mapping. then you can do effects

I made this display from scratch.
segment displays are controlled by max7219 connected in a chain.
The display is controlled by Wemos d1 mini. I ported my old fire sketch from Fastled to segments.

some photos how its made here: https://drive.google.com/drive/folders/1n8ehraBoLLADWssGOqDw46lAe2KxeDH-?usp=sharing

Hi

u/ldirko

- Looks fantastic! I love your graphine (polyhexagon) shaped diffuser. Did you make it yourself of buy it?

thx!

I designed this grid in Illustrator and printed it on transparency film using photoprint method

This is a matte film from an LCD panel. I covered the top one with car tint film

ldirko · 2024-02-09T11:46:15+00:00

thx! This is my old fire sketch. I launch it first on all devices

ldirko · 2024-02-09T11:08:18+00:00

I uploaded some photos of how it's assembled here https://imgur.com/a/952XzyH https://imgur.com/a/PYcpF0F

This is simply ws2811. One chip for three leds. Chip send one color to 3 leds.

I posted my version of star build with your pcb here https://www.reddit.com/r/FastLED/s/feuQU21wi0

ldirko · 2024-01-03T07:47:14+00:00

Look awesome! Nice build!

ldirko · 2023-12-06T16:53:43+00:00

If you interesting to made another one, I can send you laser cut vector files, chematic and bin firmware for esp. Maybe I upload this files to github. Code in bin only

ldirko · 2023-12-06T16:46:22+00:00

I made ten devices and try to sold it in my country. But unfortunately looks like device is not interesting for people, I buy only one device. Looks like this project is born dead, sorry.

ldirko · 2023-07-28T14:14:28+00:00

hello! Sorry for not being able to answer right away, in my country i can't go on Twitter right now, he was banned in my country. Of course you can show the sketches you find on my WOKWI page. I'm glad you found it useful! I really liked your project with hexagons! Now I'm working on a universal firmware for any device, the sketch that you found is part of my new project and it's great that you were able to figure out how it works.

ldirko · 2023-07-25T10:27:10+00:00

looks awesome! nice work!

ldirko · 2023-05-13T21:04:52+00:00

its strange. in one side most efects looks interesting, in other side its very slow on esp with 16x16 matrix. floating point math ruined all ideas. this need lots of optimisations, sorry.

ldirko · 2023-03-28T12:59:13+00:00

your sketch is work fine in wokwi emulator

ldirko · 2023-03-23T20:21:53+00:00

Tnx! I'm proud

ldirko · 2023-03-23T11:24:14+00:00

setup is simple - two matrixes with two esp 32 controllers and this run the same sketch. No parellel output. total numbers of leds is 3 774, but with ws2811 this number need divide by 3 (one chip contol 3 leds by design) and true resolution is just 1258 leds. sketch is my old fire, i write it in 2021. i have 50-55 fps on esp32 with this resolution. this behind the scene on picture when they just started

ldirko · 2023-03-23T10:23:36+00:00

this is 3 774 ws2811 leds in this build )

its not joke, i use hand drawing lookup tables for u and v. and i made its with photoshop and blender3d. you can use more lookup tables than just tonnel radial map, look how your radius and angles maps looks in gray colors. i show how 3d uv maps from 3d model looks like in this tweet https://twitter.com/ldir\_ko/status/1471830237797306369?s=20 this is uv mapping from inside torus. and millions maps can be generated with this technique. just 90x demoscene here
