[Technotronic27]

Super, Beautiful, Класс сделано.

[Kibawolfgd]

THANK YOU!!!!! i think i finally found something to fill that gap under my cd player

[Cife86]

i wanna build such a device, and I dont have access to blue LEDs, what would you say is the best color? green, red, bright red, yellow? I thought of bright red

[DvoroviiAS]

tell me, can maintain this Spectrum 20 Hz?

that is to make the first column is not 100 Hz, and 20 or 30

[proxymilian]

@DvoroviiAS no that is not possible

[Cife86]

how can you multiplex 400 LEDs with a single 64 pin µC??

[ssbtoday1]

@Cife86 That's wayyy more then 64 pins there...

[Cife86]

@ssbtoday1 thx cap! i wonder how are the leds controlled? AFAIK there is only one µC, the atmega64. or are there more µC's??

[proxymilian]

@Cife86 there is only one atmega64

[proxymilian]

@Cife86 The answer is within the question: by multiplexing the LED's into rows and columns there are only 40 pins used

[Cife86]

@proxymilian thanks!

Cool project, super fast cpu

[deshawnpenrose]

HOW!!!! :-0

[CrazyDood69]

I have one of these and it looks even better in person.  Super nice.

[Pitchplus8]

its nice fast. Most Led VU meters and spectrum analyzers are so damn slow in refresh rate.

[hokillmafan]

This is so COOL !!! where I can find the schematic for it ??

[keepitloud]

i want one,...

[cabelo4]

It would like an information, the Spectrum of LEDS ok, but the plate of low, for gentility which the name of it, thanks a lot  ::::: Dj Cabelo from BRAZIl :::::

[joeylawn36111]

Mine's in the mail. Look forward to using it.

[gmatta1112]

[felko2222]

busta rhymes and Dj Tiesto - C'mon (Catch 'Em By Surprise) :)

[youritronics]

Thanks Gavin,

your unit looks great but its a bit too big IMHO. I just couldn't capture the great color of the blue LED's on video. You managed to capture it better than me :)

[mriosf]

@youritronics - "...your unit looks great but its a bit too big..." <--- is it just me or does this sound hilarious? (^_^)

[youritronics]

@mriosf LOL

[MetroidChild]

@mriosf hahaha!

[gavincurtis]

You have pretty much idealized the board layout and efficiency. Congratulations! :)

[gavincurtis]

Very nice FFT! Did you see my 32 band unit?
