2.5D Edge Lighting Pixel LED Cube

LEDs are awesome, they are so tiny but bright, colorful but easy to control. Many of us start to know LED since our first lessons of electronics. And my love to LEDs started at the same time. Once I showed a LED demo to my friends at work. A girl said:I love LEDs, I gonna marry to LEDs.(she said that for real :)) I believe many of you share the same love,too.

One LED by itself is cool enough, but by the nature of human kind, we are making LEDs cooler and cooler. LED strips made one spot to a line, Matrix made it a 2D surface, some genius made LED Cubes to light up 3D space(search LED Cube projects on instructable, or check out this video, my favorite. You can even buy a 3 x 3 LED Cube kit in Radioshack for 20 bucks ).

These fancy cubes blew my mind when the first time I saw them. I knew I want to build one instantly. After some online research and messed with radioshack kit for a while. I feel it is not a easy job for me to build a big(at least 6x6x6) single color LED cube, let alone the cool RGB I want. You need pretty good soldering skills to make it work and looks nice. A lot of wiring and complicated coding.

Don't be discouraged by me though, there are good enough tutorials for you to go through. And some practice can make perfection. I just don't have enough time and effort to build this ultimate LED challenge(for me). I just want to build something nice before my girlfriend's birthday(not a whole lot time), as a gift.

Hey Fried! I made it...followed the instructions! Still have to make the proper enclosure and you are right these LEDs are crazy bright and I can't stop looking at it. Awesome thanks!

Do not have access to sand blaster, do you think a "Frosted spray" would work

Do you have the STL file for the base? I really like the design of the base plate. I was thinking of using the base plate and then using nice wood for the sides. How did you suspend the LED matrix in the base, or is it resting on the Arduino?

Friedlc (author)  jeemge015 months ago

There are 2 version of the housing now, one with the usb port opening another without.

Awesome! Thanks

Hi, I just uploaded the stl files here :

However I forgot to leave a opening for arduino usb port. So you have to disassemble it before reprogramming.

I'll make an update soon.

This is beautiful and by far the best electronics instructable idea i have seen for a while. Thank you dude, i will definitely build one of those.

Friedlc (author)  damaltor5 months ago

Thanks! Please show me yours when you finish! :D

and is the power suply ac or dc? thanks
Friedlc (author)  tgarty5 months ago

Sorry, it should be 1000uf, and it is a DC power supply. I suggest you go to the adafruit tutorial to get the latest updates.

in the sketch you'v written capitetor 1000 uf but in the list you'v written 100 uf so which do i choose? i want to be sure beforei start shoping

Hi,

The first video looks really neat! I don't understand though how you get the image onto two sides, or is that post production?

Friedlc (author)  MadWinter5 months ago

Hi,

Thanks!

I also bead blasted all the top surface of the bar, so it will catch light. You can find images on Step 1 to get a better understanding.

MadWinter Friedlc5 months ago

Ah, so you created a kind of step, that is visible through the front i guess? And because the ones in front are not blasted you can see through? Very neat!

Friedlc (author)  MadWinter5 months ago

You're right! The clear section won't catch much light so you can see through.

well i made a few led cubes my best work i think is a 5*5*5 rgb cube not that big but it works for me... nevertheless your first impressions look very cool i hope to see more of this nice idea in the next days
Friedlc (author)  Psycho4Ever5 months ago

Thanks, the tutorial is updated, hope you engoy!
