  • The Idea & How it started

    Arkadi03/21/2017 at 14:32 0 comments


    The idea is designing basic elements of addressable LED`s which can be combined into fascinating shapes.

    I play a lot with LED`s, mostly the famous addressable LED`s such as the ws2812.

    [ Sample projects: ,,, . ]

    You can get the LED`s in various forms such as strips, circles , Matrixes, bars, (Adafruit has a wide variety of shapes) or you can get them in SMD to design your own two dimensional shape.

    Images from:

    Mostly the forms aren't designed to be soldered together directly, you can solder wires between them but not to create a stand alone form.

    Based on this Gap my concept started to formalize.

    Design Process:

    I have started my design iterations with a simple triangle as a standard base element and hence the name, Trixel - Triangle Pixel:

    Later on i have extended the design for a square and a pentagon shapes while maintaining a few guide lines for compatibility between shapes.

    Design rules:

    - Equilateral shapes, side length 1 inch

    - Side connector is a symmetric (V G S G V) 5 pin castellated, spaced at 0.1 inch

    - One middle LED

    - One input, the rest are potential outputs

    Design files (Eagle) are available on GitHub: Trixel-LED

Well, I was just working on the layout for practically the same thing (the triangle one)... Maybe now I'll just buy yours instead.

That`s usually what happens :) I was surprised that i didn`t find projects as this one on the web when i started. I did find some constructions using LED`s but not Kit oriented.

The project is open source, so now you can invest your time to develop it into some new direction or add to it your own designs  / idea`s. :)

All files available on GitHub, you are welcome to fork it and share where you go with it.

Legend! I didn't see the github link before. I'll see if I can convert it into Kicad and get a batch made up, will be sure to give you credit when I win the local electronic art prize ;)

 you can ordered tested circuits from OSHParks, i did the prototypes iterations with their service.

Awesome project!  We look forward to future updates

Thanks, hope to have some time soon to assemble the next MCU module (Hexacon) and post a few more LED fixtures.

how difficult would these be to use l.e.d.s in the "grow" spectrum?

  Are you sure? yes | no

Arkadi wrote 04/06/2017 at 06:50 point

I am planning to make a Glow Plant (building a construction around a plat pot) But its not considered as grow light as you need specific spectrum of light. you can easily design pcb`s for the desired  grow LED`s but its not exactly the point of the project as the light fixture won`t be interactive. (I use addressable LED`s so you can change the light of each pixel in the chain).

Great idea, I created paper ball model from 12pcs penagonal boards ... look very good ;)
