Hey lemmings, we should do a lemmy place to compete with r/place.

I did a shitty version (64x64, shitty color picker). But it sends every change to a 64x64 led matrix.

Also it’s in my sons room, so NO, you won’t get the url XD

Well. He’s old enough to know what those rockets are. Also: That thing was full of rockets on the first day he shared the address and I totally knew it was gonna happen ;)

I’m more afraid of worse things strangers would be able to post directly to his wall.

I think you’ve confused shitty with awesome. How does that work? Like through a pi or something?

At least it was a fun father-son-project. I wrote the server part, he the client part.

First there is the web frontend (sending click requests to a script that saves the clicked pixel in a database, heartbeating to a script to refresh the “image”)

web frontend

You can emulate the rgb output:

Then there is the 64x64 RGB matrix and a raspy connected to it. It is quite hollow on it’s back, giving the raspy some place to hide:

The code on the raspy connects to the server and refreshes it’s image, if a change happened.

I also “hid” the matrix inside a canvas frame, to help diffusing the single RGBs a bit:

This is, how it looks in the dark:

Sorry for the bad image quality.

That. Is. Awesome! Such a cool project. I have a pie hanging around somewheres, is love to try something like this.

I say: Do it. Those boards come in different sizes, don’t cost a fortune AND (here comes the real awesome part) you can connect them to a big array.

Animations also look real cool on it.

If I had an Idea and the right arguments ('ello Wife 👋) I would love to build some sort of text-scrolling array of 3 or 4 those.

And while we’re at it, adding 10million more users would be great too.

But both of these don’t just happen.

Adding 10 million users tomorrow would be a disaster lol

Thank god the trash tier users aren’t as appearent here, i was leaving Reddit a couple of times before, that wasn’t a community, that was pure toxicity
