Now I've got you, Geo, "Wannabe-Technology-Wizard"! Hahaha!
What are you doing in this reality respecting technical forum, huh ???

You are not allowed to use the real working internet, you misleading person!
Go to your non-responsible LRL-freaks and play "dream-world" with them but not with us!

I see that you still stay idiot

Of course, that only for personal use. I am a student of EE and electronics is my hobby .


Only now I noticed that my PonyProg LPT programmer is not compatible with the ATmega328

Question

I could help me is I want to load the hex file.
my computer to use is a USBasp I'll show you a picture
but I want to know if I have to change the crystal by one bigger or do with that biene that is 8 or 16 I put one of you who think.

[chafik]

is felezajoo can work with 1 m * 1m coil and if so can discrimination used with 1m square coil

coil

Sorry about my ignorance but could help me,
It is that I have some doubts regarding this detector.

1. where the shield is connected.
2. that cable is recommended to connect the coil to the detector.

I'll upload a picture.

the coil nothing I can do really wired network.
if so what would be the measures of the coils.

sorry for that bad English.

[dargas]

I recommend two wires mic cable with shield like this https://www.google.lt/search?q=TAS-C...WGjoRUvNtUM%3A.

coil deep

Another question I would say the most optimal configuration for use.

It is that I made a coil but serves a while but suddenly makes a lot of noise and not shut up.

if you want to upload a video it is with version 3.35.

Hi ivconic i need some help and no one is replaying .... I made this felezjoo worked fine exept that when i plug my coil the lcd turn off and sometimes keeps on without detecting the coil after some days the atmega burned out ... Then i flashed new atmega now the felezjoo start slowly it takes a long time to get to the menu and keeps slow entering in options iam using 2 9 volts batteries here it is a picture with capacitor volts i used Please tell me what i am doing wrong

Burn a new one AtMega. I have similar problem. With a uc that programmed by a friend, detector works fine.
With 2 ucs who programmed by me the detector is very very very slow. So i need to change the programmer.

SLOW? It sounds like a fuse problem. Could you check your fuse value with extrem burner ? You can also check the quartz and its capacitors.
I have the opposit trouble with my unit. It's too fast ... i have to check the keyboard wiring.
I'm waiting for your fusse config..

[Geo]

No free time to make checks....
Maybe after one week, but i made firmware upgrade to usbasp and i am afraid that i destroy it!!! (as usually)
Any way maybe next week to give a try.

Thanx for help friend now i know the felezjoo is slow because of fuses... My problem now is hardware i think the capacitors voltage are the problem.... That´s why the first atmega got destroyed
