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
"Daddy, your Internet friends sure like drawing rocket ships a lot".
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")
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 ๐) I would love to build some sort of text-scrolling array of 3 or 4 those.
