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.

Very nice :) Just curious, how big is the display? It looks to be about one foot by one foot, but it is hard to tell. Awesome work :)

[kevtris]

it is 31*31 inches on the LED portion

[xxflinkxx]

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.

1 kw WTF !

[Fou3Fan]

@xxflinkxx yes the do. "oled" google it

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

[mentebizarra]

Awesome, How much did this cost to you? considering the huge number of RGB LED

[viciousswaggetv]

teach me please!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!



[legokidnaruto]

@IllegalMavamaarten well there ARE 12996 RGB LED's but led's dont draw that much power but eventually it does add up prettey quickly...

[richkawaiipikachu]

I love the music, What is it?

[richkawaiipikachu]

@fnord64 The answer is obvious.

Multiple footage spliced together with video editing software so we as the viewer don't have to wait for the Game Paks to be swapped.

Simple as pie really

Are you insane? Over 20,000 RGB LEDs?

OK, you are insanely insane because the power consumption of this is 5kw, not 1

And it takes 15 seconds to create the full picture :(

So, what's its size? 32 inches?
