[sdiy]Stereo plasma VUmeter demos...

[Larry Troth]

Marc

Will these run directly off of the 10v p-p (+/-5v) of many modular synths?
If not, what modifications might be necessary to make them work that way.
I'm thinking that a really neat 'retro' module could be made that would show
the CV or Audio synth signal patched in, with '0' being in the middle, -5v
at the bottom, and +5v at the top.

Even more fun, NixieStore is selling a 'lot' consisting of 5 x IN-9 purple,
and 5 x IN-13 orange for $19US.  Make 4 boards, 2 in purple, 2 in orange,
put them into a single MOTM/Synth.com/Modcan/Frac panel and keep the extra
tubes as spares.

Hello,

Thanks for your positive feedback :)

IN13 ( or IN9) tubes are available on Ebay . I suggest NixieStore from
Moscow.
He is reliable, cool prices, serious packaging and fast delivery . No
problems
after a couple of deal ... No, i am not sponsored by him ! :/

About the THAT2252 RMS detector chip, SmallBear NYC sale them. May be they
are
available from other places too. Other parts are classic things easy to
find.


Cheers,

Marc B.
