[boo400078]

HELLO I AM MARWAN FROM IRAQ THE CIRCUIT IS GOOD DEGZINE FINISHING PLEASE CAN YOU SEND THE SCHEMATIC CIRCUIT TO MY EMAIL

MARWAN_ELECTRONIC@YAHOO.COM

[SomeRandomMacGuy]

can I have the schematics too, thanks

[MGwandy]

any chance you're still handing out this schematic? this is great!

[antros48]

fucking awesome!! well done!!

[raviteja250890]

hii ....u did a great wrk ...can u send the description and ckt diagram of this project ....my mail id is ....mandigart@yahoo.com

[jasoncasemusic]

how and where can I get the link for the making of this device. I would love to create one myself. Thanks!

[domdomgin]

can someone please give schematic and code to domdomgin@yahoo.com..

[pkdon3010]

Hey Buddy can u please tell me the name of the song playing.....

[koolariz]

i get it now. you use 10 bandpass filters?

and you use the pic only to drive less or more leds/line, according to adc value.. no fft calculations.

you took the easy way out :P

fft in logarithmic scale would have been smoother :D but i don't think the pic can handle that much computing..

i'm currently trying on a 16bit to implement fft and i'm nowhere :P

not giving up, though. cheers

[flybymyway]

awesome work dude......

cn u pls share the link whr u hav posted the code...

[flybymyway]

awesome work dude.......

hv u made this using microcontroller???if yes then which ???

[djjaxon]

Hi there, been looking at a few videos of spectrum analysers and yours is great, it seems to be very accurate, would you mind sending a copy of the schematic?

[12345coolieonit]

hi, please could i have the link aswell?

[Petroskaixeropsomi]

 α ρε, Eλλάδαρα power

[yigitguducu]

good song great job!!!!! awsome!!! could u send me the schematics please? i need this until 2 weaks

[bing257]

Can i please get a link to the schematic of this, it looks great

[M0nsteray]

Can you send me the schematic, great job!

[haseeb18oct]

Could you send the schematic diagram too? What's the name of the song?

[haseeb18oct]

Could you send me the schematic diagram of this circuit too. I appreciate. btw what's the name of the song?

[babupsp]

Bro can i have the schematics pls...

[kukutur]

It looks amazing! I want to construct something like this. Could you send me a link too?

And one more thing: what is the name of this Kaiti Garbi song

[mechazirra]

I'd love to see a schematic as well. I'm having a TON of trouble on my analog filters for something very very similar to this, so I'd love to see how you did it. Nice work.

[NTComputer86]

can i get a link to a kit or schematic, this is awesome

[mik3big]

I have sent you a link

[NTComputer86]

Thanks!

[billynightmare]

@mik3big can i have a schematic too please?

[stnasos]

Swstos!

[sirc4526]

nice job! amazing

[angrysurgeon]

Hi man, great work! whats the name of the artists playing on the mp3?

[mik3big]

Thanks for the nice comment.

She is a greek singer called Kaiti Garbi.

Search for her in youtube.

how many input and outputs to the PLC?

[mik3big]

First, i am not using a PLC but a microcontroller.

I used 10 analog inputs, one for each frequency (column) and 20 digital outputs.

Also, I used another analog input to control the refresh rate of the LEDs and another digital input to control the mode.

[mszeineb]

I love the song as well :p

[mszeineb]

LOL it's cool! Great Job

[mik3big]

Thanks

[mast3rbug]

So, you are using Analog filters at each input to filter frequency? Why not using only one input and do the filtering digitally? A lot less parts on the board.

[mik3big]

That is right but you need a DSP to do that plus knowledge of digital filters.

[beneeeto]

do you have de proyect in document? diagrams, code, ect!! I would like make it!!!

[mik3big]

I have them but I can't post the link here.

[d3dreaper]

Does anyone know where i can find schematics for a Spectrum analyzer that doesn't use a pic or micro controller??

[mik3big]

You can use LM3914 or LM3914 to control the leds.

[JAFTFLIFP]

very nice

[jpm000001]

very nice, what uC did you use? And is that a homemade PCB back there?

[mik3big]

I used PIC18F4685 uC and yes, the PCB is homemade.
