I read about pass meter maybe one year
before now

I search for two weeks now but i cant find
them anymore, sorry for make the same.

Can someone help me to find that threads ?

If we implement the meter (vu meter maybe)
can we use direct or must use another PCB
like jackinij made ?

Is there some one here implemented them ?
Would you attach picture here ?

Where to find the meter look a like ?
Is they expensive ? How durability ?

Is it the same way if we implement digital ?

Your "Meter" really cool Mr Pass
