"..Hi ivconic,
? Is it a challenge ??? .."
No, it is not. I have ...around 50 000 different transistors here...
On photo only showed my favorites (most used)..There are 2500-3000
transistors on photo only....Who wants to challenge anyway..?

"...And IVCONIC you cant tell by first sight expecialy if someone
explain to you and you cant see with your eyes.Everyones misstakes..."
Yes, i agree! As man of honor i would not back my previous words:
"If your PN2222 is different than CBE...than send it to me by mail
i will eat it infront of the camera! I swear..."
Only, no need for you to send it. I have enough here to eat!

Max:
"PN2222 USA pinout CBE
BC2222 Europe pinout EBC
C2222 Japanese pinout BCE"
Max, this is very strange!? I am Euoropean. Never used or saw any
2222 with EBC in my life!?
My favorites (and most used) are BC... ! All of them i used so far
are CBE ???!? I swear!
Except few obsolete's, out of production now... Also "BC2222" ???
I think there is no BC2222...! I never saw it!
Or C2222...?? Or 2SC2222...never saw it!

Only transistors (small signal,TO-92) i am using, with EBC are:
S9012,S9013,S9014,S9015,S9018, MPSA13,MPSA14,2N2907....!? That's all!
But...as TikTak said: "...Everyones misstakes..."
As long as man live, he learning...Today i learned much!
Thanks a lot!

Best regards!

Hi ivconic,
"around 50 000 different transistors here" wow man ... really huge number! I Think I have something like 10000-12000 only , don't know!

"Max, this is very strange!? I am Euoropean. Never used or saw any
2222 with EBC in my life!?"
Yes, I'm European too... know that's not so easy to see but there are! Found one time also BCE stuff (C2222) in a Korean made radio. I never heard of BC2222 too... never saw any... but that indication was just to explain to TikTak how stuff works about transistor "zone" identification... BC is the common mark for low power mid-freq transistors in europe (BC547 , BC 237...), but who knows? maybe they exist for real!
Maybe there are clones of original 2n2222 or PN2222 marked in different way.

I've found many strange stuff in old asian-made devices... sometimes strange things like the C2222 I've reported... I saw it, and cannot find in any table etc and even if they arent in any catalog they exist. I think that some asian manifacturers make that devices just for related factories...manifacturers, using jap pinout...and that mark, so I think they cannot be considered as "standard devices".

Also, people here must consider using right datasheet for devices, e.g. 2N2222 (metal case) is a different thing respect to PN2222 (or MPS2222). Different pinout, different intended use (first small power rf, second as general purpose tr).... of course, internally are about the same but if you look at motorola and on-semi datasheets for both you'll note some differences.

Fact is that is maybe the widest used "general purpose" and so people think that there's always same pinout and same specs... and in some cases it's just not true.

Best regards,
Max

What do you think people? It will work or not?
I'll post schematic these days....

Why waiting?
Here it is!

Hi ivconic,
I think lm339 mod would work great. I have some dubts on TL082 instead of two LM308... these dubts is related to hi-fi audio circuits experiments I've made with dual op. amps... never get good results where there dual pramp... and expecially TL0x2 series... but they aren't preamp there.
Maybe there would be ok! Think that only way to know is made a prototype.

Also you could exchange TL082 with other things (e.g. NE5532) if a few mA more is not a problem (and many other newer stuff with very low noise if you can find).

Why not!? circuit would be even smaller!

Best regards,
Max

Hi Max.
Can you help me with my questions below.
Thanks

Nelson

Hi Nelson,
as I've measured DD22 again, data are:

Former diameter used for one halve = 18.7cm
Outer diameter of DD coil = 21.7cm
Wire diameter/gauge 0.25mm(30AWG) measured without varnish (0.28 with varnish)
Tx turns = 120
Rx turns = 120

Tx resistance = 23.9 ohm
Rx resistance = 24.1 ohm

Tx inductance = 5.65 mH
Rx inductance = 5.76 mH

(but keep in mind that no instrument is perfect so could be minor tolerances)

What's strange in yours is that when you tight them you get too much increase. I wounded copper wire on former, then spiral wound with tape, then shield them, then another wound with tape. And that's all....
I get that data, just 0.2mH increase of inductance, respect to unshielded pair , not more.

So I think your problem is in that bigger increase.

About 28cm I don't know cause I don't use that diameters in my coils... but think ivconic's data are really good.

Best regards,
Max

Have a look at this, it's AWESOME for ID'ing unkown devices!!

HI MAX, YES I KNOW IS VERY STRANGE WHAT IS HAPPENIG WITH MY COILS, BUT I ALSO KNOW THAT I M DOING SOMETHING WRONG. FOR EXAMPLE FOR 28 CMS IVCONIC COILS, I HAVE FOLLOW ALL INSTRUCTION HAS IVCONIC DID, BUT WHEN I MEASURE RESISTANCE THIS ON 30.2 OHMS FOR 120 TURNS, THEN I CHEKED WITH ANOTHER ,ULTIMITER AND READING IS 30.8 OHMS, NOT TO MUCH DIFFERENCE, SO THIS IS SHOWING ME THAT RESISTANCE IS REAL. WIRE IS 0.25 MM OR 30AWG, WICH I ALSO MEASURED TO BE SHURE IT IS THE CORRECT ONE AND IS OK. FOR COIL FORMER TO MAKE THE COIL, I USED A METALIC HANGERS, SO THIS CAN BE TURN TO ALLOW YOU TO REMOVE THE COIL. I ALSO THOUGTH THAT THIS METALIC HANGERS COULD BE THE PROBLEM, SO I TOOK MY COILS AND MEASURE RESISTANCE AND INUCTANCE AWAY FROM THE FORMER AND I GOT SAME RESULTS. CONSIDERING THAT RESISTANCE WAS 30.2 OHMS, I CONTINUE MY JOB, THIS TIME BY PLACING A CORD TO IT AND I GOT 7.4 mH (FIRST READIND WAS 4.89 mH). THEN I PUT THE I GLUED THE COIL, MEASURE AGAIN AND SAME LAST RESULTS. I PUT AL FOIL, CONNECT ONE WIRE TO THE SHIELD AND FINALLY TAPED, AND I GOT NOW 30.2 OHMS OF RESISTANCE AND 10.4 mH OF INDUCTANCE.
ALL MY COILS THAT I HAVE BUILD HAVE THE SAME PROBLEM.
WITH MY LAST COILS WICH IS 27.5 MM INNER DIAMETER, I MEASURED THIS AFTER IVCONIC SAID THAT HE FORGOT TO SAID THAT THE 28 CMS IS FOR INNER DIAMETER, NOT OUTER DIAMETER HAS I DID, SO MAY BE THE PROBLEM IS WITH A FEW MM THAT I HAVE LOST, BUT I REALLY DON´T THINK THIS COULD BE THE REAL CAUSE OF THE PROBLEM.
FINALLY MY 27.5 MM COILS WITH 80 AND 85 TURNS, 9.6 AND 10.4 mH AND 20.6 AND 21.3 OHMS OF RESISTANCE, WHERE NULLING AND TESTED AND RESULTS DIDN´T CONVINCE ME , 17 CMS 15 CMS FOR A 12 MM COIN.

TAKE A LOOK OF WHAT YOU HAVE DONE, 22 CMS COIL WITH 120 TURNS OF 0.25 MM WIRE AND FOR IVCONIC 28 CMS COIL, SAME NUMBER OF TURNS, SO WHAT IS REALLY WRONG WITH MY CALCULATIONS, I DON´T KNOW, BUT THIS IS TURNING ME OUT OF MY MIND.

ANYWAY, I LL TRY YOUR 22 CMS COIL AND SEE WHAT IS REALLY HAPPENING.

THE ONLY THINK I KNOW, IS THAT THE PROBLEM IS MINE, I KNOW THAT I M DOING SOMETHING WRONG AND I WILL NOT REST UNTIL I FOUND IT.

THANKS FOR BE PATIENT WITH MY EXPERIMENTS.

HEY MAX AND IVCONIC, TODAY I HAVE MEASURED THE RESISTANCE OF ONE TURN FOR A 28 CMS IN DIAMETER COIL (120 TURNS TOTAL) AND GOT 0.2516 OHMS PER TURN. (28CMS BY PI= 87.96 CMS AND 87.96 CMS EQUAL 0.2516 OHMS) SO IF YOU THINK FOR A 22 CMS COIL, WIRE USED MUST BE 82.93 METERS LONG, 82.93 METERS DIVIDED BY 0.8796 CMS= 94.2814
94.2614 X 0.2516= 23.72 OHMS, VERY CLOSE TO YOUR OBTAINED VALUE MAX.
I HOPE THIS IS CORRECT. IF SO , MY PROBLEMS COME TO CLEAR.

hi

Hi,
Max I have told you that this transistor were brand new from shop and I have discription on some metal case one from this shop!
But its marked as PN2222A only!Nothing else.Usualy there are some other numbers also on all parts,but on this there arent!
Any way thanks again for your advices.And ivconic help also.
Now to coil:
I have measured TX 18,7 and RX 18,9 resistance for coils.
Ivconics way.
I have played for a while and found good point!
Around 25 cm for coin!Hip-Hip-Hurey!!!!
Two coils conected to pcb without shields!
THE PROBLEME IS REALY THIS WEEK AUDIO!!
Its like pik-pik !Not good!
How were you solving this problem?I think that there must be puted some resistor or what?If so which value?Where?
See you soon!

Hi,
audio is always weak on tesoro's... trick is find some good speaker, 16 ohm would be ok... but only one that I really trust is one I've found inside an old apple computer... with other good things that I've used to make bandido II !

But yes is weak, too weak and you could lose stuff when searching on real field. So use always headphones. Belive me, I missed much stuff first time using it ... then used headphones in same place and got triple of stuff in the same time (about 2hours)! (bullets, shells, brass, copper, lead and gold too etc etc)
Another solution could be using the zahori audio , as Ivconic described somewhere in previous post, or also the Leto's solution, an audio amplifier that seems really good idea.

Best regards,
Max

Hi,
all this talking about GS tempted me...

and so here we are !

(have to find some time to make that stuff somehow!!!)

[tiktak]

Nice work!
Its very enjoiable!@!!!
I work much,but havent sleep for a 2 days and everything were ready!
I sleep less than 3 hours if I am lucky to even get some!
So its nice and easy!

[tiktak]

Ivconic can you please post this changes in audio?Like all untill now!
Zahori's and Leto's?
I have read this many timres,but still fog!
Thanks
You and max were right at the end it will work

Hi,
metallic case ??? PN2222 in metallic case ??? strange.
Anyway, metallic case 2222 are 2N2222 (to-18 ). Look at the picture.

The small piece outside indicates E, the central is B and other C.

Start enjoying GSabre

(Have to drop my acrobat reader in the trash can... one day or another)

I like .JPG schematics!

Kind regards,

Hi,
ehm yes... required me much efforts... about total of 40minutes of work!
Smoking cigar also that time! Trick is "kind of a fog" ?

(or good positive pcb, film and UV-radiations ???)

I think that Fog is half work here!

So keep smoking my friends... at least when you try to make PCBs...

I suggest 1 Montecristo/PCB minimum

Max
