DIY audio spectrum kits.
 
Hey all!

Does anyone know of any DIY audio spectrum kits off the net? I'm wanting one for an amp I'm building.
I've been looking around with little luck, I found one but it costs $225 which i think is a bit much :eek:
Would there be a way of pulling apart a screen from a cheap tablet off eBay an modifying it any way?

Any suggestions are welcome :)

This is the one I found; 20 Band Audio Spectrum Analyzer (assembled) [v2.1] - $140.00 : Youritronics, shop for electronic kits

Apologies if I posted in the wrong section!

Cheers :)

You can even buy a cheap second hand laptop and use some software.

I would try an arduino with some of these:

These bars are cheap, and someone made code for 4 leds here:

Looks like the one you found also needs a controller.

Any idea where to buy some?

I would look at sparkfun, they have arduino's and led bars:

https://www.sparkfun.com/search/resu...&what=products

If you go the arduino route (which is fun), i would first ask the same question at the arduino forum. Most likely someone did something similar and can tell exactly what you need.
Also i think sparkfun is not the cheapest reseller, for instance i can buy those led bars for €0.85 in the netherlands.

Here is the arduino forum:
