someone has been surf PI oxygeno07.
mine keeps ringing, with or without coil and heats the Q6 (BC337) someone has any idea because it can be.
thanks.

comprueba que te valga, un saludo.

Hola oxigen007m puede usted poner el pcb en espejo en el formato pdf pues deseo imprimir el circuito mediante la tecnica de laser toner.
Desde ya, muchas gracias
Carlos

Hello oxigen007m can you put the pcb in mirror in pdf format because I want to print the circuit using the technique of laser toner.
Of course, thank you very much

Excellent work Oxygen007m, (Tormod too).

Thank you.

Thanks, Tormod. I see it now. It was very observant of you to find that.
The Surf PI looks like an excellent project - especially considering the low parts count.

Hi.
U/B is a misprint, should be U7B, pins 4 and 5 where crossed, explained that in a PM to oxygen007m, and he corrected both the schematic and the PCB.

Oxygen007m, Tormod, I don't understand what the error was. Sorry, but I can't figure out what is meant by "om U/B".

I've looked but cannot find any difference between the "repaired" schematic or PCB layout and the originals. Were the crossed signals in the schematic, the PCB, or BOTH?? Would somebody please circle the change so that it stands out and does not get lost?

By the way, good work on the board layout. Thanks!
Cam350 sure looks useful and interesting.

The fixed PCB :
I also attached the final printout of all layers you need to have .

With a great apologize for a small error found by dear Tormod
and a great thanks to him for precise attention to schematic .
The error was true and I was wrong . However I fixed
them and now we can claim that the circuit is ready to build .

[oxygen007m]

The control pin 5 and out pin 4 om U/B seems to be crossed?

As I said before there is not any problem with the schematic or pcb .

[Tormod]

I think there might be an error in the retrace?

Hi oxygen007m, exellent retrace and also a good design for a single sided PCB for surf 1.2, just what i have been looking for.
I think however there is a small eror in the circuit. The control pin 5 and out pin 4 om U/B seems to be crossed?

hi oxgen007m How is the result of metal discrimination in your machine how the air tested
thanks..best regards

It is just a retrace of original schematic with some minor changes of parts
being used and therefore the results of operating tests will be the same as
original one .
