PICKINI V4 - an easy to build, self adjusting PI detector

here if you assemble a generator for your md, then chuika is much more with small coils ..
since the differences from your scheme are not great, then it is insignificant to make changes.

have you got the firmware for the 12f675 ?

Also your chips are standing far away from pcb, which could be problem, each leg conductor acting as antenna, inducing emi into circuit?

in fact, it is not needed there. When printing it turned out separately from the common bus, but it converges already at the bottom. this is not a problem.
minus, he and in Africa minus

Pickini cant work in most of housing area in my place, even with shielding, bring it far from the house area and it will work.... And change ur coil as spec.

@popka-ru

Thanks for the waterproof housing suggestions. I will see if I can get those type of fittings here in Australia.

Sorry to hear you are having difficulties with your board.
The only suggestions I can make are to try cleaning the copper side down thoroughly with alcohol to remove any leakage between tracks and to check signals with an oscilloscope if you have one.

Try making other coil as was suggested.

[dbanner]

I also think making a different coil might be answer to problem.

You have ground loop on pcb, not good, generate oscillations.

there it should be, since it is a common "-" when printed under the loot, the toner fell off a little and had to be brought up. this is the common minus bus. it looks like you do not recognize your own signet.

Don't use computer power supply? Use battery.

[dbanner]

No, it looks like that is OK

You may have a short on circuit board? Look here:

all, I do not want this md !!! does not want to work. all the details completely replaced with new ones. Several times he checked if the seal was correctly made. all came together with the scheme, but still does not want to work, even on the street. all the time constantly ticks, it's not just not convenient and annoying.
