DIY PIC12F1840 microcontroller based metal detector project.

hello teemo. i like too much your project, so i build the circuit but when i try to burn pic12f1840 with pickit 2 programer the program said error in the line 0x000000. i try with the pickini v3 hex and is correct. i like this design because the trasmiter is beatifull. thanks

	All unused pins need to be grounded through a 33k resistor and programmed to be low, for starters.

Hi GD thanks for that tip, just to be clear should all individual unused pins have its own individual 33k resistor to gnd
or can each unused pin be commoned  and then to gnd via one 33k ?

	i need yo know what programer for to program the pic 12f1840. thanks and bless you

.

The programmers are not expensive. Digi-key.com or mouser.com or sparkfun.com, all sell pic programmers for the 12f1840 pic chips.  If you are in u.s.a. go to a frys electronics store , they are a big electronic store that sells inexpensive programmers too.   Best Regards Eugene

повторил проект, получилось не очень, хотя все номиналы соответствуют. очень тяжело запускается катушка, но путем пробы, добился не стабильного но запуска. на феррите 10мм намотал 300 витков 0.4мм проводом. и кольцо 50мм тем же проводом 150 витков, все работает, но чувствительность на все не белее 4см. жаль, поигрался и подарил ребенку, он во дворе насобирал кучу гвоздей и пробок. дорогой конструктор для такой слабой игрушки!



Translated by MOD.  English Only Please.  repeated the project turned out not very good, although all denominations correspond . very difficult to run the coil but through trial , it has made steady but not start . at 10mm ferrite wound 300 turns of 0.4mm wire. ring and 50mm in the same wire 150 turns , it works, but the sensitivity to all not whiter than 4cm . wish to play and gave the child , he had collected in the courtyard of a bunch of nails and plugs . expensive designer for such a weak toy !
