QED

[6666]

i also plan to do two stage front end preamp for both - P-cnannel and N-channel MOSFET pi designs -
that will give you 5us of the delay. it will like kinda some converter you can fit in any PI.

Any idea when this will be released ?

Once i made DP to work at 600pps. It was very sensitive to smallest targets... but also unstable on soil too...
DP needs GB channel. That would be the improvement!
That's where QED is superior when comparing those two.

soon as possible. i try still to persuade Joe to sell me his surf pi board. people have to have posiibility to get surf pi original copy board.
and i would like to cover up surf matter too.
its hard for me just mine poor english.

That's like the English saying: "A bird in the hand is worth two in the bush".

russian one is better be cause more colorful IMO =) sinitsa is small bird, zhuravl is big. a sinitsa in the hand is worth the zhuravl in the sky.

another way, an accessable schematic in the hand is worth QED for AUS $1200.

Yeah, we`ve gone from the QED being ready to the QED not quiet ready in a month, in another month it`ll be we`ve been here before. That bird in the hand is truly worth more than 2 QEDs in the bush.

Better so, than to announce a wanna-be hi-tech detector half years before real sale and in months following, patching vague technology with a funny terrain use of yellow ferrite rings.

WM6, if your talking about the Z, it ain`t a wanna-be, let me assure you it is a killer hi-tech gold machine. Well proven in the gold fields and well worth the initial wait, hopefully the QED proves to be well worth the wait too.

QED is not ready yet ...

[WM6]

It is on sale for more than month.

Sadly, demand are way higher than supply (it is one man manufacture behind). This is why "AVAILABLE SOON" remark.

If you are interested to stay in order line, this the right site to go (contact site owner):

I am not interesting for the time.
The only thing that i want is to read comments from users to see if it's really so good.

[WM6]

According first users reports, seem that QED owners are satisfied with QED performances.

Hi KT315, did you finish this project ?

Hi KT315, did you finish this project ?

hi 6666, no... no yet requests =) you are first asking. i am ready to finish, but....

you see no deep interest...
people fly in the sky with diamonds... they prefer to kid.

what in my plan now..
1. small board for solder iron to control its power. this is popular schematic from the past.
2. DP layout correction
3. preamp for vlf coil. a way of ML to get those gold 2 inches depth+.
3. some board for testing - opamps of any kind, generator for checking of coil, sinus vlf generator. whole on one board.
