TESORO GOLDEN SABRE

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?

[Pompey]

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

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..

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.

En la imagen ESA posicion de los transistores es la correcta viene?

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?

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

May depend on whether made in Europe or US too.

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.

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

TO92 case.. Here you go.

[dfbowers]

TO92 case.. Here you go.

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

[simonbaker]

TO92 case.. Here you go.

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

[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.

El transistor utilizado para mí es esto y parece que el transistor 2N2222A.

¿Tendré problemas con el transistor KSP2222A?

[nakky]

Use this.

I have it installed.
Not worth the ksp2222a transistor instead of the 2N2222A transistor?

Very nice @lunamay,

Seeing the successes of others will certainly motivate those who would still like to start with this very exiting TGS project.

It looks like the TGS and TGSL both work, so apparently both PCB's are OK.

Has anyone actually build both versions, the TGS and TGSL, and compared the obtained results by using exactly the same Coil? If both designs give similar results, then I would like to build both TGS and TGSL. Everything about this project very much appeals to me. I wouldn't even mind to write a complete Build-Up Manual for both designs with photos tips etc.. But then I would like to receive some feedback to work on. I have purchased MIL Spec Components for the TGSL, and the best-of-the-best for capacitors, resistors, coil wire etc. But it's completely useless to others to make a Write-Up by using these components in an article, for regular obtainable Components will be used by most in any case. Interesting though, is how many MIL Spec Components I see in Metal Detectors from Top Brands. But I suppose that not all of us will be Hunting at -50 °C, and Dynamiting holes into the rock solid ground. But maybe it's only me who likes using explosives, which leaves me thinking? Am I only motivated by treasure hunting, or just the heavy banging during blasting operations. I never seem to find anything after a blast, now I wonder how that can be? Don't wet your pants on this one!

Regards,

Robert

It looks very nice. I congratulate anyone who finishes one of these babies, including myself on the rare occasion. Looks like you put the GB pot on the outside, I'm usually lazy and use a trimmer on the PCB and don't adjust it much later.

I think you made the TGSL Final version, correct?

TGSL Tuning & troubleshooting thread is another good one to continue with any detailed questions and problems. Keep us informed how it works and any progress.

Cheers,
