Most probably version 3.30 is not working properly due presence of bootloader.
I just finished "patching" of annoying counter at version 3.23 and now i am checking it and testing it.
Soon i will post video to show it.

jladre,
flat spider or basket, what kind of coil you raccomand?
And with or without shield?

Just make like this depend on your area. I used it at white beach so i dont need shielding.

Thanks

I believe so, the only ones i could source quickly were used ones from a reclaim company, pulled from old equipment

Thanks.

would it be possible for you to take a reading with your multimeter for me please, if you cannot thats OK.
I am interested in what dc voltage you have on pin 23 with no target, and coil away from all metal, thanks.

I understood from previous posts that you cannot test the 328p pulse out without a coil connected, is that still the case ?

@ivconic, its still on english language.

Ok, that's than because characters and words are twisted due code conflict with bootloader memory allocation.
It will be solved by omitting the bootloader.
