[quote = simonbaker; 111293] 2N2907 y BC547 han colector / emisor en lados opuestos de acuerdo a las hojas de datos. Así que probablemente correcta si utiliza las piezas exactas que se enfrente.

Puede depender de si se hace en Europa o los EE.UU. también.

********************

Espera, ahora veo lo que quieres decir. 2N2907 y 2N2222 se dibujan hacia atrás en el dibujo de diseño de piezas de EE.UU.. (Sin embargo, puede estar correcto para Europa, no estoy familiarizado con ellas.) Creo que el foto (imagen inferior) es correcta (Por partes de EE.UU.).

Pero echa esquemático, no confíe en forma de las partes.

Sería bueno agregar c, b, e las etiquetas de los transistores en el lado de diseño serigrafía.

Finally I think I know the pins of the transistors if I'm not confused. I looked at the schedule for hours. When building the test coil and hope it works.

I am from Europe and America may change the pins in some transistors on the Europeans.

If anyone is encouraged to investigate different types of transistors in parts of the world and put it in this forum would be very useful for beginners in electronics.

TO92 case.. Here you go.

Handy, thanks. And PCB needs e,c,b labels to match.

TO92 case.. Here you go.

Oh. from left to right : American, Japanese, European.

[dfbowers]

2n2907 and BC547 have collector/emitter on opposite sides according to datasheets. So pictures probably correct if you use those exact parts.

May depend on whether made in Europe or US too.

********************

Sorry, now I see what you mean. 2n2907 and 2n2222 are drawn backwards on the layout drawing for US parts. (However, may be correct for European, I'm not familiar with those.) So I think the photo is correct (for US parts).

But check schematic, don't rely on shape of parts.




It would be good to add c,b,e labels on transistors in layout silkscreen side.

Hello, I'm trying to build the detector tgsl and I have some doubts.

In the image a look of some transistor to one side and two in the picture look the other way.

In that image the position of the transistors is correct?

Wait, now I see what you mean. 2n2907 and 2n2222 are drawn backwards on the layout drawing for US parts. (However, may be correct for European, I'm not familiar with those.) So I think the photo (bottom image) is correct (for US parts).

But check schematic, don't rely on shape of parts.

En la imagen Aspecto de las Naciones Unidas ALGUNOS transistores de un Lado de la ONU y dos en la foto de vista la gorda.

Always try to read the data sheets of the components.

I'm making as in the first image. Why the second transistors are placed in a different position?

Too many versions that although the model and see if I can not be trusted. Have contradictions.

Do any of the two images is valid or not valid any?

I always check components before installing them with a multimeter. If you do not have a multimeter look at the case type of the transistors you are installing against the spec sheets and compare that with the schematic.

Even if I'm sure that I am installing things the right way, it's nice to know that the components that you are installing are working beforehand..

Have a look at the www.datasheet.com for transistor pins.

hi guys

can anybody help me and draw a connectings of pots and switch? i would be very hapy...best regards to all

And this one in case you're building the TGS version

regards ,

hi guys

Maybe this helps. Others can correct it if wrong.

If you don't like the direction the pots turn, just reverse the two outer connections.

This is for TGSFinal PCB.

P.S. It would be good to add a better drawn similar diagram (with coils, speaker, power supply added) to Qiaozhi's TGSL Complete Details thread.

[simonbaker]

Separate Thread

A lot of interesting coil and general info being added here -- but can we move it to separate thread when not specific to TGS?

In fact, would be interesting if Qiaozhi, Ivconic, and Max made a project to clean the TGS thread of digressions by moving them to other threads. It would be good to keep just a link to the digression that is moved because it is part of thread history.

MineLab's 11" DD Coil uses Graphite Paper as Coil Shielding, and NOT Aluminium Foil or Copper Foil!

... 11" MineLab DD Coil ... The two loops of wire one was Litz Multi-strand the other one was signal strand very thin wire that's the one that broke of. To hard to count how many turns there were. Shielding was like you said Graphite Paper. Also had a earth wire taped to the Graphite Paper. I didn't take a photo of it before I fixed it and glued it back together didn't think of it. Hope this makes sense to you. I don't know much about making coil yet still thinking about making one. I do have 14" DD Coiltec Coil that is a bit noisy I should cut it open and see if it is a easy fix as well if I do I will take a photo of it and put it on here ...

Note:

Apart from the Coil being Graphite Paper wrapped, maybe Graphite Paint, or Spray Paint, may also be used to coat the insides of the Coil Housing too (just an idea).

Carbon:

Graphite is a Hexagonal allotrope form of Carbon, and a Diamond has a face-centered cubic crystal structure of Carbon called a diamond lattice.

Graphite (WikiPedia):

http://en.wikipedia.org/wiki/Graphite

Interesting:

@A.J. van den Hul uses Carbon Shielding (LSC - Linear Structured Carbon) in his World renown TOP-NOTCH Audio Cables. Certain Cables are referred to as being Metal Free! And Cables in which Copper Wire is used, are made up of OFC (Oxygen Free Copper) wire strands.

Remark:

These were just the results obtained from 10-15 Minutes Googling, and by no means my priority choices. So you will find yourself well on your way, if you put more time and effort into this matter. I just wanted to give you an idea about MineLab's Graphite Paper Wrapping there Search Coils, and how you may apply there knowledge into your own Coil Design(s).

Enjoy!
