Delta Pulse

[raff33]

Hello forum,
I have read over the forums that the 4066 must be a CD4066 wich is TTL. I could not find CD4066 so i"ve got 2 pieses CD74HCT4066E and also i"ve got 2 pieces of CD4016BCN. Now on a previous post on some of the forums i have seen on a so called Original Dp Schematic a combination D9 4016 and D10 4066 working toghether on same circuit. I wonder on the Orinal Delta Pulse this is how they used 4016 with 4066 in combination?? And what would be best to use ...if you have it experienced...

Marius

for me i have CD4066 bcn without probleme

Thanx Raff
I am using cd4066...
The detector works better end stable ...with that cd4066 ...
The only problem i have and still can"t find from where the problem comes when comes to detection distance....at one moment the detector started to work incredible i used to get a coin at 30 cm...but not far later the detection sensitivity decreased again and now again im geting a coin at 17-20 cm... with the 1x1 coil 16 turns im getting a large gasoline canister at 1,60M in the air wich is poor....i wonder from where the problem comes...

hi Marius,
what you do?
c1=15nf or 22nf * c7=220uf or 1000uf * R1=680k or 470k * R5=2k2 1w or 680R 1w * R6=680R or 1k * R47,49=2k or 1k * PR1=200k or 220k..........?
and i think if you have some ciramic composants........(your probleme)
sorry for my bad english

postoje razlike izmedju seme i pcb-a:
D9 , D10 (4066) pin14 ide na +12v po pcb-u a na semi ne
D9 , D10 (4066) pin 7 ide na -E po PCB-u a na semi ne
D2 ,D3 (453 pin 16 ide na +12v po PCB-u a na semi ne
D2 , D3 (453 pin8 ide na -E po PCB-u a na semi ne
R47 , R49 -1k ili 2k
R! 470k ili 680k
PR1 250k ili 220k
C1 22 nf ili 15 nf
C7 1000mf ili 220mf
C32 4700 mf ili 10000 mf
sta je ispravno?

hi kt 315
I've actually received an instruction uses with the sniffer very short
but I wanted to learn more about the realization of a square coil of 1mx1m
n being a connoisseur like you
I prefer not to commit any imprudence
Geo has answered my question on another post
I will advise you of the progress of the construction
especially if it works

cordially

esus, I HAVE gave this link. why you ask me again? follow these pictures and you will build the coil

good luck
