What does the Pulse Rate come out to with that ? You can't get any more Basic and call it a PI.

What about LM324 as replacement for the quad op amp?

I think ist a pirate with one chip.......
I want a real PI

LOL, You said Simple. That's technically not the Pirate. It's just about the most Basic PI you could do and call it a PI.

Andi simple does not always mean that its easy to build and get working, how do you know that you want a PI pinpointer, what projects have you built ?
also can you list your expectations of what you want a PI pinponter to do.

-off resonance detector, nearly 20 years ago, my first detector
- pirate, but it doesn't satisfy me

I think the Pirat is the simplest, then the one chip and this, then the polish pi,surf pi, baracuda.
