Giant Big Blue DJ Audio Spectrum Analyzer With Tupac Rap Music

Big Blue Audio Spectrum Analyzer Prototype 24" X 48" display array connected to the same PIC16F877 control board as in my other videos.

Size comparison; the display is sitting on 3 full size file cabinets. The computer monitor at the left is 19".

True realtime display; visually it is fluid and organic looking; not choppy like the video compression shows here. Touching the frame toggles between bar and dot mode.

Despite the high output from the LED's, the entire system still draws no more than 20 watts from a Radio Shack wall transformer when all cells are illuminated.

Song used in this example is Tupac's California which produces one of the better animated displays.

Sorry about the bad video capture quality...

hi, o bought one of your spectrum analyzer and it works very good but i have a little cuestion, can i conect it to a lcd color display???

[gavincurtis]

@fireblade639 Why would you want to do that?

[powerdon215]

Man, I don't have BIG dough, but can a novice build this?

And how do you get info to do so?

[gavincurtis]

@powerdon215 Yes. Processor and LED driver kit is $165. But the big LED display like this one in the video (pre-built) can be yours as long as it will fit in the trunk of your Bentley ;).

oops I saw where the kit comes with a schematic to build the array. is there a way you can put in a "peak and hold" option.. I think that look would be incredible.. also is there any way to remotely trigger the unit on and off? its only going to be in parts of my christmas display...

@eldoradoboy

EEPROM is used to remember analyzer mode so when it powers up so it stays the way you remember it... also some other register data.

Everything else is operating in RAM.

But dangerous if EEPROM becomes corrupt. A good programmer needs to look ahead and see all possible failure modes.

what did you use to actually construct the display case itself, not the leds or driver? how did you separate the individual light cells and what material is the outer screen?

[mutewit]

What did you use for the display array? Thinking of making an analyzer myself I initially planned to use LED bars behind a screen of sorts but this looks much better.

[sliferion]

soo... how much are we talking about? :D

Greetings from Denmark

where to buy this kit for the audio analyzer ?

I cant find them on ebay or on the internet ; please help

:o)

nice music

[Vocoder07]

awesome!!!!

I bought this kit for a fun project to build one day and never even took it out of the bubble wrap. It comes with all instructions but I really doubt I'm ever going to get a chance to build this. Brand-new never opened. Kit was $165 on eBay. Anyone interested in buying it from me please send a message to me on my Youtube channel. Selling it for $100 firm via Paypal. thx

Gavincurtis,

Are you still selling the Audio Spectrum Controller on eBay? I'm interested in one, thx!

[fox9419]

Really nice work there mate. I am thinking about buying the $165 Audio Spectrum Controller off eBay, and I have a few questions about that magnificent display of yours.

Question 1) It’s a 16x16 display correct? How many LED's are in each "pixel"?

2) How difficult is it to build something like that? I have a bit of experience in electronics like soldering and all that.

3) How much approximately would that display cost in total?

4) Possible to use a lightbulb as a "pixel" instead?
