I saw rgb 7 segment displays once, it was beautiful.

it's 80x100mm

23 leds means buy 100 get 4 digits - nice!

    My ascii 'little a' is 98, according to my array. Not sure why. But here we have: text! Finally - before I was running the demo script from adafruit.io, that surely looked nice.

    I wanted to power my arduino and the wsb2812bs from the same source when running, but didn't want to kill my usb port when programming, so I used some diodes from a rectifier.

    Black plastic was by choice, I was afraid of color bleeding, if I print in white. I added a coat of primer spray and will later spray it white for highest reflectance. Not sure about the toplayer yet. Might print something with z-glass from zortrax finally.

Great project! I have a similar one but only for 7 segment. Did you write software for Arduino or Raspberry Pi?

I'm thinking of building a similar display with APA102 2020 size... Should be a fun journey!

  Are you sure? yes | no

davedarko wrote 06/07/2017 at 18:21 • point

Hey Maksim, thanks! The software runs on an Arduino, but with wiringpi it should run on a pi as well.

Sounds like a cool project, those 2020s look very nice!

  Are you sure? yes | no

I have a bunch of these, regular sized that i need to do something with, pretty sure they are red, I got an entire tube of them.

  Are you sure? yes | no

Wow, this really came out great. Kudos Dave!

  Are you sure? yes | no

Hehe thanks Mike :)

  Are you sure? yes | no

Elliot Williams wrote 04/26/2017 at 20:25 • point

Mike, you have to see them in real life!

  Are you sure? yes | no

Damn fine project! I thought my upcoming 60x30mm RGB 7 segment would be unique, but yours looks amazing.

How much space is between the LEDs and the front? As I've got no 3D printer I am building my version with laser-cutted parts.

  Are you sure? yes | no

davedarko wrote 03/05/2017 at 15:23 • point

Yay, thanks! it can't be much more than a centimeter (checked, it is). The display itself is 10x8 cm2.

  Are you sure? yes | no

davedarko wrote 03/05/2017 at 15:24 • point

if you have to decide because between 3mm and 4mm and between 8 and 12  resulting in 9 or 12mm, take twelve.

  Are you sure? yes | no

Elliot Williams wrote 10/05/2015 at 19:05 • point

Saw this in real life.  The paint job works perfectly as a reflector. It is beautiful!

  Are you sure? yes | no

Stefan-Xp wrote 10/04/2015 at 15:15 • point

Nice Progress!

But i really wonder how the Back of the Digit looks after you soldered it ;)

  Are you sure? yes | no

davedarko wrote 10/04/2015 at 15:38 • point

ahh, you want to see the dirty details, don't you? I wanted to have something to show on saturday, so I rushed the prototype :)

  Are you sure? yes | no

jaromir.sukuba wrote 10/01/2015 at 13:39 • point

Now let's make equivalent of 16x2 character LCD made of those displays!

  Are you sure? yes | no

davedarko wrote 10/01/2015 at 19:47 • point

that's gonna be slightly pricey :D

  Are you sure? yes | no

Stefan Lochbrunner wrote 10/02/2015 at 17:11 • point

I second that idea! Come on Dave, you know you want to ;)

  Are you sure? yes | no

deʃhipu wrote 09/29/2015 at 08:01 • point

Hmm... you could display whole words by having each letter a different color, and blending them... I wonder if you could "scroll" them by moving each of them through the hue...

  Are you sure? yes | no

Stefan-Xp wrote 09/28/2015 at 22:57 • point

Great Project! ;-)

As long as it glows, its my thing ;)

  Are you sure? yes | no

davedarko wrote 09/29/2015 at 06:30 • point

Oh it will :3 in so many colors that anyone would only ask "Why?"

  Are you sure? yes | no

davedarko wrote 09/29/2015 at 06:30 • point

But I still don't get the usefullness :D really makes no sense.

  Are you sure? yes | no
