Hello,
I have a few (10) IN-9 Bargraph tubes that I no longer want, thought I'd
ask here before I list them on eBay. Anyone interested?

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.
As for why 7 channels, I found a little IC that breaks down audio into DC
components (7 to be exact). I have found a fft that runs on AVR
microcontrollers but am not sure of its accuracy or how quick it is. So for now
I'm using the IC. I will definitely investigate the fft when I can.

Yes, I've seen a lot of neat ones on YouTube. All of them are rather large,
though. My board is 3.2 x 1.25 if I remember correctly. So hopefully that's an
advantage.

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.

Some time ago, I purchased a 13LO7V Russian oscilloscope tube. I
haven't been able to find much information on it, so I figured that I
would ask here. The only datasheets supplied are in Russian, and while
I understand most of it, a lot of it still doesn't make sense.
