seems a west coast custom's works... but at the end is very easy to put and if needed to remove it).

umm

I have some good IC that I would like to exchange for a Cuban cigar. I am only 1/2 kidding.

Whoops, despite all the freedom Americans are told of, freedom to smoke Cuban cigar is not amongst. I purely forgot.

I was 100% lying. I lied. God Bless America.

Despite all the BS. Cough cough GAAAAGHHH

Hi,
well yes... the two things don't match at least in theory... I mean smoking a cuban cigar and blessing...

But you have to be realistic... there are lot of offices in Washington D.C. that smell of cuban cigars... even if people sitting there will never admit that... so why don't you smoke one too !

I find relaxing using the cigar fog as catalyst for electronics... things go always well using that stuff... who knows why ?

Anyway, just my 5cents to coil making!

Kind regards,
Max

From local craftsman, i had difficulties to persuade 2 of them to make me those! One is already making TV antennas, sort of small bussiness, dealing a lot with Al pipes all sizes. Other is "plastician", making things from plastic....
But since i had not enough money, i oredered small series (10 shafts and 20 coil housings) so they hardly accepted to work on this.
With a lot of effort...nervs...finally i got it!
Next time i will be pushed to order at least 100 pieces if want to be done!? Sort of blackmale! But thats life...
Regards!

Hi Ivconic,

Please let me know the next time you need to place an order. I'm sure there are many people here who would also like to buy some of these stems and coil housings. Together we can place a much larger order.

"Have you find the LM308?"
Actually Strujas gave me LM308H (metal case). Indeed you were right!
Better relation S/N! I suggest now LM308H to be used!
Short anecdote:
I was in a hurry to test those so soldered few wrong way!!!
Started to count pins from small notch!!! So pin under notch was "1"!!!
When switched ON TGSL started screaming pretty loud. I was confused.
First thought was "it cant replace LM308N..."! Damn!
Later dug out what was the problem. I was 100% sure those are burned!
What a waste! But "small warm" in my head pushed me to correct and replace
pins in proper manner (same ic's). Again tried and.....working!Hurraahh!!
Not burned! Alive, and working pretty good! Miracle!
SO PAY ATTENTION FOLKS! UNDER NOTCH THERE IS PIN NUMBER 8 , NOT 1 !!!
This can happen only to people like me....not to smart people!

"Got 5.62 mH inductance, giving me a freq. of 14.69Khz on TGS, R=23.1ohm !"
Max i made same coil twice. First with 0.25mm and second with 0.3mm, just for
comparsions. Have a feeling that one with 0.3mm is a bit better!?
I suggest you to do the same and later post here your remarks, please.
Of course, number of windigs should be corrected a bit...few more for both coils.
You will gain less resistance of course. But those will work fine even resistances
are down to 18 ohms approx. No worries.

"A picture is better than 1000 words."
You got that right! I agree. Photos you posted giving me exact picture of your work.
That coil will work very good!

"I wish to you good works.."
Giasou Geo! Pou ise? Ti kannis? Kala..?
Long time no words from you Geo. Nice to have you back!
"A Guy from Bulgaria ..."
Yes i conntacted him. 27cm cost 4.6e in Sofia shop. Less than i payed for those my housings.
But when calculating shipment,post taxes, maybe some custom taxes......prices will be
leveled for me....Other thing is that his housings are made from pure plastic, but my
i ordered to be made from fiberglass - pretty stiff, no jitters later. Although i
recommend those Bulgarian coil housings too! Had few in the past - very good!

"THat's astounding. I wish you the best of luck in hounding, er, convincing your "almost"
suppliers into providing your needs."
To tell you the truth; money is most convincing thing on this world!
Again Max, nice work! If i had such sharp camera as yours!

About cigars; ehm, all those antismoking campaigns initially came from USA! Land of Marlboro,
Lucky Strike.....and much more brands!? I dont understand this? I am smoker. If i get cancer
than it is my problem.Why all those people are trying to stop me, limit me,prohibit me...?
What about other bad things arround us? Smokers or not,USA comes on the top of the list with
most of cancer deseases....How come? Such nice American way of living, helth,gyms,beauty saloons,
"ugly is forbidden"...Huh, i should stop! This is not subject here! Sorry!
RObert is back, we meet ocassionaly. His influence on me is obvious! Sheeesh!

P.S. Just to add; remeber Michael Moore? The smartest,most human,most funny American i ever
saw in my life! Long live to Michael! Personally i would like to meet him and express
my admiration to him and his work! If anybody of you know him, please pass the very best
regards from me!

Hi Ivconic,
yes works very good, tested just 30minutes ago... and still wonder of how good it is.

Got 1eur coin at 36cm easy on air on the test bench just keeping halves fixed with tape on a flat board !

Very good. The half-crown (that is 32.5 mm diameter) at much more maybe 40 who knows ? I haven't measured at all... just too amazed by results.

Nulling is (at now) around 4.5mVpp very hard to get cause tape is no good for that torsion forces on bigger coil and have to use much for test to keep them aligned.

Now... the big problem for me is applying a right shield (they are now actually unshielded) puzzled between what to use this time... wanna use mylar but have few... ad don't know if good idea ... maybe I'll use a bad kitchen roll, very thin al.... and of course... finding a right coil-housing to seal it.

I'm very happy with results and suggest anyone here build this configuration for a good compromise between coil dimension and depth.

Of course... I've done nulling smoking the Che's cigar... but that's obvious.

Best regards,
Max

PS. I'll test 0.30mm wire... but at now I haven't... run out of it and used 30AWG for halves. Have to find at least 150meters to perform the test... I think also could give better results than 30AWG.

a strange idea for a challenge

Hi Ivconic and all,
I was thinking last evening a thing... well I'm not sure of that... anyway that's the idea/thought:

Can the TGS or TGSL with large coil like this DD255x137mm halves win the Carl's cache-test ?

I mean detect a jar full of e.g. silver coins at 24 inches deep.

I think it can do that: 24 inches are about 60cm... and if you consider using neutral soil (easy) with not too much iron-crystals I strongly think it can do that... in spit of all of the "top of the range" thousands dollars deep-seekers that actually can't !

Ivconic what do you think ? Is that possible for you ?
For me it is possible using easy/neutral soil.

I haven't the 220 silver coins to run the test myself but maybe someone has already and can do the test for 24'' detection.

Also I'm not truly interested in testing that... but I read something that cache-test is impossible to be passed by MDs... and just wonder of one saying that... cause I/we know good PI can do that... but till now maybe nobody proved it true with an IB/VLF (true discriminating) machine, like TGS is !

Any idea ?

Kind regards,
Max

I made 12 TGSL's so far.All working nice! But have noticed minor differences among them; some of them can produce ocassional,very short false signals....all checked with same coil...It is not coming from coil but from device itself?? What should be a problem. I lost myself in soldering all those pcb's....Need hint on which stage should pay most of attention about stabillity....

Hello Ivica.

Have received the LM308N I had bought in Hong Kong (see mail Esteban) so now made some test. It looks like you can make some improvement if you chance the freq. comp.
for the LM308, I removed the 100 pf caps(C22-C30)and made the freq comp. by placing a 18 pf cap on pins 1 and 8. When you make the boost switch ( 1M resistor) the sound stays quiet, no erretic noise ! Caps from 8.2 pF made a large reduce in sens.
Can be that the value need some more experiments.

Succes.

Hi ApBerg,
thanks for the hint ... I'll test too.

LM308

Hello Max.

Well.... there was, for some 40 minutes, no erratic sound, then suddenly it became erratic again , just like it was triggerd by something.
The power was the same, near the coil was nothing moving !
It is more quiet but there is still something that makes the golden, at full sens, instabel. Reducing the sens a little solves the problem...and it stays very sensible, ....

Let us know your results !

Best regards.
