144*144 RGB LED Matrix Gameboy

Here it is! Finally, my set of 12 RGB boards showing full frame (almost) Gameboy video! (True gameboy rez is 160*144).


Tech specs:

* 144*144 RGB LEDs on 12 boards
* 20736 LEDs in all
* About 1KW power consumption on white screen
* Full custom control panel designed and made by me
* Ability to run 16 boards (I need 4 more)
* Full 24 bit RGB supported via 30 bit PWM
* All firmware, FPGA designs by me.

Impressive stuff man, getting so much custom hardware to work :) And I applaud the usage of Purple Motion tunes :)

How are you running gameboy gfx, from a gameboy itself?

[kevtris]

yes there is a real live colour gameboy connected to the FPGA board which is driving the 12 LED boards. No PC was used during operation, it is entirely stand-alone.

Absolutely fantastic effort! I have been an engineer for nearly 20 years... and I am very impressed by your effort!

BTW. If your display is 144x144 pixels and each pixel is RGB then aren't there actually 62208 LED elements!?

[kevtris]

yes, that is correct. 3 dice per LED, so the total count is 144*144*3.

I really like this music and I know people have posted possible ways to find it but searching on the net and such have yielded no result. Where can i get this CD or Album?

[kevtris]

It is an S3M format music module. You will need a MOD/module/tracker plugin for winamp or similar to play it. Googling "S3M plugin" might yield some results. The actual S3M is called "Starshine" and is by Purple Motion. You can get the S3M here:

only in football stadiums and such, the marketed "LED" tvs are simply LED back lights, with LCD displays. They dont produce tvs that use leds for individual pixels.

Fantastic project ! How long did it take you to build it ?

[SpiralPegasus]

Wow. Just... wow. Impressive is the least I can say.

How long did this take to be done?

[skudave]

Word. Absolute sickness man, cool project !

What's the refresh rate?

[TheBakachan]

Gator pinball! Oh man, I'd forgotten all about that game. It was one of my favorites. I still have my original grey gameboy from the 80s, but I've lost all the games. :<

[Fou3Fan]

yes the do. "oled" google it

[heydude85]

sage!!

Purple motion - Starshine

Just a question:

Its seens that you are doing 2 scans at the same time, (2 column scan?)

so, only 1 led at a time per row is lit at the same time (3 leds to form a RGB led).

But 1 entire row, in the worst case, is entirely lit... that makes 72*3 = 216 leds

2 scans, top and bottom - 216*2 = 432

lets suppose that each led uses 20mA. 432 * 20 = 8640mA

9A +/- to feed this monster??? :O

I suppose you are using 5v

5 * 9A = 45watt??

Correct me if i'm wrong. thanks
