felezjoo PI(the best pulse induction metal detector that I made until now)

[folharin]

fiz 3 aparelhos e 3 verc?es..mas nenhum deles serviu aqui...terra vermelha muito mineralizada, deveria ter um balanceador de solo manual

[folharin]

I made 3 devices and 3 verc?es..but none of them was able to be used here...very mineralized red earth, it should have a manual soil balancer

[folharin]

I tested it in the sand of a soccer field and it worked very well

[folharin]

however when I use it on mineralized soil it does not store the soil configuration and every 2 seconds I have to do the soil adjustment

melhor aparelho para minha regi?o at? agora foi o tgsl... ganhou o minelab safari e o fisher f5 que eu tinha

[folharin]

minha ca?a favorita ? o tgsl at? agora..ele venceu o vanquish e muitos outros..

Hello,

Someone can recommend me a coil configuration (type, inductance, size) for good search (rings, coins) on the beach? Thanks.

Thank you!

I finished building the Felezjoo, but it is too slow to start, it takes about 5 minutes to go from the start message to the menu and when it is there, the joystick commands seems very slow to respond, anyone else having this problem? Thanks.

Thanks for the help!

I got it working, after bricking an Atmega, I burnt another with usbasp and avrdude from mac os terminal with the commands below:
avrdude -c usbasp -p m328p -u -U flash:w:felezjoo_full_M_3.35_.hex
avrdude -c usbasp -p m328p -U lfuse:w:0xf7:m -U hfuse:w:0xd1:m -U efuse:w:0xfc:m

Now it's working normally.
