Surf PI Pro

[stefan646]

I am slowly putting the board together using the latest PCB made by ahcene2035 with NE555 instead of ICL7660 (the LT1054 is quite expensive :-" ).
The only thing I don't understand is how I trim the R2 pot (the one that sets the time of TCL555). After what frequency I am looking after? Or I must trim it based on the best detection range?

Just because pi is taking so weak I did. 20-25cm at most. How to get deeper.
Sadece Pi'nin ?ok zayıf aldığı i?in yaptım. En fazla 20-25cm. Daha derin nasıl.

Hello fellow enthusiasts, I have done my suf xx, And I am happy with his work. My question is, would hearing sensitivity be changed if the output stage for the candlestick was done, like PI Polonaise, or like with a Delta pulse , using a single NE555 ic?


I apologize for English, I use google translator
