Note: for firs and second version hardware use diferent firmware. Good luck!

hahaha im still dont have luck not working

ok i retest back

[Eddy71]

Any other. All work with 12f629.

[paku]

omg
where is hex for PIC12F629
cos im use PIC12F629

[Eddy71]

This .hex for PIC12F683 only. In PIC12F675 or PIC12F629 this firmware not work

[paku]

i using hex file version PinPoint683v5f.hex
my ragulator im using LM317L is that have problem

[Eddy71]

You programm microcontroller with firmware? Check voltages (like on schematic). As beeping detector? (sound i use for show errors in pcb)

Sorry Eddy71

The Board Is Not Working

[Koala]

I built one of these as a pinpointer. Worked so so. Sometimes worked fine other times need turning on and of a few time for it to work correctly. Might dig it out and wind a new coil for it.

[Stefano]

It's wound on a plastic support. At first I tried to wind it on a piece of ferrite hoping to get more sensitivity but I found out it was too much unstable.
I recall it seemed to react to changes in orientation.

HOW ABOUT THE COIL I WANT USE THAT FOR PINPOINTER

[Stefano]

First version, not very sensitive but not bad.
IMHO a continuos tone instead of the beeps would have been better. Asked the author about but didn't receive any reply.
