Re: [neonixie-l] IN-13 Spectrum analyzer

[Dan Foster]

I'm assuming you're talking about the analyzer? The spectrum analyzer chip is 
MSGEQ7, which comes in DIP-8 and SOIC-8. You can find it on sparkfun in the DIP 
package, but the SOIC version is harder to find. I'll dig up the place where 
you can get it if you want.

Mind sharing the component part number?

As for why 7 channels, I found a little IC that breaks down audio into DC

I'm using the IC. I will definitely investigate the fft when I can.

It would be cool to make one with more channels for analyzing the 
quality of your amateur radio transmissions.. Something to think about 
for another day. :) My Swan 500c puts spurious emissions all over the 
place. I probably don't want to know what they look like. :S

Hello everyone,
I am thinking of selling a IN-13 spectrum analyzer, either fully
assembled or in kit form. I've just ordered the preliminary
boards to get the final prototype together, but it would be 7
bands with a 3.5mm jack input. 12v input from wall power, and
possibly a mini USB port. The final product would be around 3.5
inches long and 1.3 inches tall, with the tubes going up from the
front. Below is a render of the enclosure to give you an idea of
how it might look. I'm still deciding on whether or not to leave
the sides open. Let me know what you guys think and if there is
enough of a market I will produce some.
Thanks!
Dan
