Nixie bargraph as a audio VU-meter

wim · 12th December 2006, 06:00 PM

I bought some nixie bargraph's (IN-9 and IN-13) an i intend to use them as audio VU-meters for my amp, but i seems to be a hard job to "google" a schematic to drive them.

Is here anyone who can help me getting a schematic or so?

Thanks anyway.

National Semi has a series of bargraph drivers which can be configured as nixie drivers -- search on LM3915, LM3916 etc.

Interesting, I didn't realize there were such types of Nixies. I still thin the Magic Eye tubes look better for this use, however.

Hi DIYers ! Did anybody ever build a dB scaled bargraph with nixie IN13 ? These have a cool oldlooking orange area but work in a linear way . Any idea for a tubed circuitry for a log amp ?

Cheers

Google for "in13 nixie" and the first hit is this:

As usual, the neonixie-l group on Yahoo!!!! is your friend. (I note that several of us lurk here, including the incredible Alek and his home-made tubes - he's still the only person we know to have made a home-made nixie.).

See the files section:
Files > Other readout technologies > Neon Bargraph Indicators

For drivers, see:

VU driver for IN-13 & IN-9

Various driving strategies for IN-9 & IN-13

A simple kit to play with...

I think it would be interesting to build an RTA with 31 of these.

Has anyone here built a very simple circuit with, say, an ECC81 / 12AT7 driving the above. What I'm thinking of is two bargraph circuits to monitor the cathode current of the OP valves. (current mirror ?)
