hi Nelson

I mean Diode 1n4148 look near fet.
check transistörs. one is near led.

Hi erolunall.
I checked all 1N4148 and are ok.
Now i ll check transistors. I suspect that the problem is on the receiver stage of the circuit, but i don´t know where to check it first.

My Delta Pulse!

Hi!
I am have build too the delta pulse and the zahori , is very good all , the delta pulse i'm build three coils , and I am in use an coil of 3,7 ohms and 30x30 cm. I am build changes in the delta pulse...
Coin .................40 cm.

I am live in south of Brazil , i am not have good english. Good 2008 for all.

Hi Nelson
Your coil with 9 ohm can not produced instability.
Seem as you use wire with small diameter. Approximately
3-3.5 ohm will be good for delta pulse.
Trouble shooting without oscilloscope will be difficult.
You can see here amplifier out put waveform, pin 1 of tl062.
First pic. Without metal near coil .
And second pic. With metal near coil.
Width of pulse Wave form increase when metal near the coil.

Hi my friend.
Still having lots of things to do.
Yesterday a friend of mine, offers me a Fluke 96B oscilloscope for sale. This is a almost new equipment and he is selling it at U$$300.
I search the net and the price for this oscilloscope is btw U$$850 and 1000 dollars.
What do you think about this equipment?
About Delta pulse, will be checked when i get the oscilloscope.
About Bounty Hunter TR 840, will be full checked when i get the necesary equipment to do the job.
Now i m still working with coils for my TGS, cause i have lots of diferences on coils and performance values.
Best regards.

Hi Nelson
I search Fluke 96B in the net, it is handheld scope meter
60MHZ, 2chanel, DSO. Also suitable paying 300 $ for it.
You can use it for alignment delta pulse.
But in my opinion better if you found some another oscilloscope
And select the best. Also you can use analog oscilloscope regarding
Value for money. For delta pulse suitable any type popular oscilloscope
With 2chanel , 10 MHZ bandwidth, input amplifier sensitively,
5milivolet per section .
Best regards.

FOR GIOVANI

BOM GIOVANE TAMBÉM NÃO É TÃO LONGE ASSIM.
VOCE COMENTOU QUE CONSTRUIU O DELTA P. E FEZ UMA BOBINA TRIPLA E CONSEGUIU UM ALCANCE DE 40 CM PARA UMA MOEDA.

VOCE PODERIA ME DIZER QUAL ESQUEMA VOCE UTILIZOU( POR QUE NESTE FORUM TEM VARIOS). QUAIS MODIFICAÇÕES VOCE FEZ PARA QUE ELE FUNCIONASSE BEM? DESCULPA PERGUNTAR MAS VOCE TRABALHA COM ELETRONICA?

YOU SAID ABOUT THE DELTA PULSE WHICH YOU USED A TRIPLE COIL.
RANGE 40 CM IN AIR FOR ONE COIN
WHAT SCHEMATICS YOU CHOICE WHAT MODIFICATIONS AND IMPROVEMENTS YOU MADE.??

Thanks aft_72005.
Yes i ll buy Fluke 96B, cause some friends toll me that is a very good instrument and the price is a real oportunity. Some not LCD scopes with 10 Mhz bandwith here, are sold for U$$300 or more. So if this scope realy can save me money and most important do the job for what i need, i ll get it.
Tomorrow i ll tell you more about it.

Dirceu trabalho com eletronica sim , eu usei a versao do Kt315 , aquela que falta uma trilha entre pino 2 e 6 do IC D8 , eu disse antes que fiz 3 bobinas , e a ultima eu estou utilizando , é a que com canos de PVC , ela é quadrada , 30x30 Cm. , não é muito boa para objetos pequenos , mas objetos medios ela é bem sensivel , utilizei um fio usado em YOKE(bobina defletora) esse fio é do tipo liz , ele é varios fios pequenos em um só , não sei bem o diametro dele , pois nao tenho como medir mas acredito que fique entre 23/25AWG. Dei umas 14 voltas na bobina , ainda estou em fase de testes com ele , o PCB eu fiz a mão(usando esmalte) mas ficou bom numa placa dupla face , só tive que usar soquetes torneados pois assim ficava mais facil de soldar por falta dos furos metalizados , evito postar no forum pois meu ingles é ruim e eu tenho medo de ser mal-entendido , era isso ... Um abraço...

Hi friend Nelson
For coil, you can use 0.5mm CU wire, 23 turns, with 40 cm diameter .

Hello,
Did someone here made this deltapulse PI with LCD?
What are the results?
Did it work on soil,hot rocks,etc.....?
Thanks
