TESORO GOLDEN SABRE

[Orbit]

A resonant capacitor in the RC of 15nf 33nf I replaced the receiver and I edited to be like at Tesoro lobo 1EUR got to 38cm in the air and I tried to land a Euro 30cm in the country is stable.

[Orbit]

The following changes that I did that I replaced with a 1n4148 diode 2v7 and turned white as the classics, I also op amp 358 off 330k and 33k and the weight I put 1k as done last degree of white classics

[Orbit]

Trimmer for the impact of the country confused with the 100k potentiometer on the panel and remove the boxes, try these changes you will be extremely satisfied with your device

Dependence of the number of turns, voltage and field in the coil.
L~N^2
I=U/X(L)~U/L~U/N^2
Consumption: i=I/Q
The energy of the fields: E=1/2*L*I^2~N^2*(U/N^2)^2~(U/N)^2
Energy fields in the soil, is proportional to the voltage and inversely proportional to the number of turns in the coil (^ 2). The best ratio of voltage to coil is two times higher than the voltage source.
*FORUM (MD for You)

Because of this, the value of the Tx coil by Ivconic recommended, very bad solution. 60 turns to Tx, is a better solution, more stability and better sensitivity.

Thank ORBIT

Hi Vladimir. This is tested, but still I feel the solution to th oscillator which is connected to the audio oscillator is not in your head, every move and at least change th oscillators ocsilatora-frequency sound.

La serie umax son lo que evolucionaron a partir de la serie de Sabre, por lo que las bobinas que figuran en la serie umax debería funcionar. La cuestión de la bobina original era el 8 "Ronda concéntricos.

No es suficiente para su bobina de tener solamente buenos profundidad de detección. También debe tener buena discriminación. Tener una "especificación original" bobina de fábrica puede ser una cosa muy buena para que funcione. [/ Quote]


The coils I will price a little expensive. I think I'll build more coils internt. I own 23 awg copper wire (0.25mm) 20 AWG (0.5 mm) and 21 AWG (0.7 mm).



I built a coil in the form of D and I used 23awg wire 120 turns for 110 laps for RX and TX. The results were dismal.



That copper wire which I have can work better and be more manageable to build the coil.

problem

hi everybody
which kind of coil should i use to test coil? the left one with difrent coil winding direction(pink arrows) or right one with same winding direction?
both coils are shellded and taped

best regards

According to my wire gauge charts, your wire gauge conversions are mostly incorrect.

http://www.allem.com/wireengr.html is where I got my information (from the Magnet Wire Dimension Chart)

23AWG = 0.570mm (bare, ~0.62mm with enamel)

20AWG = 0.8128mm (bare, ~0.86mm with enamel)

21AWG = 0.7239mm (bare, ~0.77mm with enamel)

30AWG = 0.2540mm (bare, ~0.285mm with enamel)

One interesting detail about the "AWG" wire system: as you go down by 3 wire sizes, the wire cross sectional area and weight increases 2x (and resistance will decrease by 1/2).

As an example, 20AWG will have twice the weight and 1/2 the resistance of 23AWG (for two wires of the same length). This all may be unimportant but is sometimes useful to know.

What is important is that if you have 0.25mm wire (approximately 30AWG), that is a very good choice for making a light-weight coil for the TGSL. If your wire is instead 23AWG, this will make a coil much heavier than is necessary.

You will find the answer to your question by monitoring the output of the pre-amp, relative to the TX signal, using a 2-channel oscilloscope. If the RX phase-shift is 20 degrees, the RX coil is the correct way round. If it's 200 degrees, then swap over the two connections.

[quote = porkluvr; 111449] Con agreement De Mis Cartas de cable calibre, Las Conversiones de calibre de cable es hijo de su Son correctos Mayoría.

http://www.allem.com/wireengr.html es dónde son los cantantes Tengo mi información (Por El Imán de alambre Dimensión Chart)

23AWG = 0.570mm (desnudo, esmalte Con 0.62mm ~)

20AWG = 0.8128mm (desnudo, esmalte Con 0.86mm ~)

21AWG = 0.7239mm (desnudo, esmalte Con 0.77mm ~)

30AWG = 0.2540mm (desnudo, esmalte Con 0.285mm ~)

Un Detalle Interesante Sobre el Sistema "GTE": una Medida Que Avanza Por 3 tamaños de cable, el cable de la Sección El transversales Y El peso aumenta 2x (y La Resistencia sí reducirá en 1 / 2).

A modo de ejemplo, 20AWG Tendra El Doble y peso de 1 / 2 de la Resistencia de 23AWG (dos cables de la Por Longitud MISMA). Todo ESTO PUEDE ningún servicio Importante Pero es un Veces Útil sable.

Lo Importante es Que Si Tienes cable de 0,25 mm (30AWG aproximadamente), es MUY BUENA Que Una Elección párr La Toma de Una Bobina de peso Ligero PARA EL TGSL. Si es por cable EL, EN CAMBIO 23AWG, ESTO Hará Una Bobina Mucho Más Pesado de lo Necesario. [/ Quote


Todos los hilos están disponibles para mí como el esmalte y el esmalte está incluido.

Una de las preguntas. Piensa lo mal que se ha construido la bobina debe detectar una moneda por lo menos dos pulgadas? (Change rx and tx joints in all possible positions and remains the same).

He construido dos detectores de pulso y algunos rollos funcionado mal en mí, pero al menos me detectaron una moneda a 4 pulgadas. En tgsl sólo detecta una moneda a una pulgada. Soy un peso que algo anda mal en el detector.


Muy mala traducción, lo siento.

Hello again.

Tgsl built discriminate well but detects shallow. I built three coils around and DD with the measures outlined tgsl but caught very little.

Can someone check if polyester capacitors are bad?

Also I have another question. N22 is the same 220N?

Greetings

N22 means 0.22nF=220pF

Hello again.

... Can someone check if polyester capacitors are bad?

Hi @Verdi_248,

N22 is NOT the same as 220N!

Capacitor Coding's:
http://www.mikroe.com/old/books/keu/02.htm

If the mark on the capacitor is 120 the value is 120pF, 1n2 stands for 1.2nF, n22 stands for 0.22nF, while .1µ (or .1u) stands for 0.1µF.

Your Capacitors are wrong !!!

If a n22 Capacitor belonging to the same series as the 220nF capacitor, has about the same size, then the the voltage of this n22 capacitor should be far higher than the 220nf capacitor (verification check).

You can also build an audible test oscillator with a 555 chip and a 220N capacitor, and then swap it with a n22 capacitor. The frequency should then be 1000 higher, and inaudible to the ear.

Strange, I replied at about the same moment as @mikebg, and yet there is 19 Minutes time shift.

Robert

[ApBerg]

Hello Virdi,

Both , Mike and Robert are giving good info, but on the pcb where is standing N22 you need to place cap's from 220nF.

Regards.

I'm buying the correct capacitors.

Thank you very much everybody. Then I will comment if it worked the change of capacitors.

Sorry for the translation
