Kia Ora (hello), I'm looking for a basic sound meter circuit. I found
one but it uses a LM3915 IC, and I have no idea where to find one of
them.
If you could help with schematics, or even some info on the LM3915
(ie, a more common IC thats still in production, or a subtitute) It
would be realy useful!
Cheers,
Tim
