GB -- "VU Meter Amplifier" PCB

jackinnj · 31st July 2006, 03:02 PM

I am thinking to implement this VU Amplifier circuit, have PCB's made -- L1 and C2 adjust the Attack and Delay (and can be changed as needed.) The circuit is from a design by Jon Munson in EDN in 2005, and I have simmed it with good results. Probably around $5 or $6 for a 2-channel board using through-hole devices:

2 channel Board + components + meter movement for $6.
You are without doubt an optimist.

that's not what i have in mind, i know that meter movements cost more than $6, i was wondering if we can have the meter movement also together with the boards...i hope i made mysself clear this time...

As we say in the States "Read the prospectus carefully before you invest". I typed PCB.

At any rate, I have sold many hundreds of amplifier PCB's -- if I can panelize the boards and cut them here in my shop the price will be lower.

I also thinking of adding a simple logarithmic converter so that you don't have to screw around with the meter face.

This could definitely be interresting. I could sure need a bunch

Hello jackinnj

Maybe you will find further informations to your VU-project here:
http://www.ethanwiner.com/meters.html

Also, one of the finest VU-meter companies are the Sifam. Home-site here:
http://www.sifam.com/vuppm.lasso (I have bought VU´s from them)

If you could make PCBs I will order at least 4-6 boards from you

Regards

I'm also interested!

Does anyone know if this will work well with the Corning pH meter Model 7 meters you can buy on eBay?

I searched the EDN site and found Jon Munson's article on the above design. ( Then I saw that jackinnj also linked to this in another thread. )
