Thanks for reference looks good. Looks like they put a sync pulse into the capacitor timing input -- hey, if it works... This chip needs external coil "buck-boost" type looks like, 300uH not to big I guess, but other 7660 just need capacitors. Usually type with coil higher efficiency though I think.

Another design possibility if you're feeling creative instead of sync pulse is to let the voltage regulator free run and use it's oscillator to drive TX coil; an idea I'd like to try sometime.

Cheers!

Hi,
free run mode is no good: intermodulation between md timing signals and analog with converter clock.

Kind regards,

I meant use voltage reg oscillator to drive TX coil, everything in sync!

Glad you are back, hope all is well.

Hi,
I'm back just for a while... have to think something else... but problems are still there.

I think it's a good idea sync converter with tx stage.

Kind regards,

Hi,
thanks, you know... I cannot think about problems all the time... so I relax a bit here looking for interesting stuff (actually distracting myself from the troubles and bad things I see - unfortunately - everyday).

It's kind of brainwash, needed to go ahead these days... so will be not only about technical posts... maybe some sarcasm here and there...

Like Dr. House maybe ?

Worse things around...that I see, enormous troubles...as example... yesterday I saw a young, beautiful woman die... not a good thing to see, belive me...that's why I cannot sleep much these days.

Sure... I know this is OFF-TOPIC here so I will not write more about.

Kind regards,
Max

Hi,

Hi,
Ivica.
How are you?
I have solved my problemes with TGSL1265.Now its almost complete.Bad capacitators!Now I am changing all of them.
Can you please tell me where I have to attach this small PCB with the monostable?To GND or -8V?
Thanks
Its a lot quieter than TGS.
I like it.I use the old setup with 2X2n2907 and 2X2N2222 all metal.And now just for tests TL081 insteed of LM308.I dont have a pair now.I am waiting for one soon.

Glad to hear your still around Max , I am working away from home for several weeks , Its terrible to be in an area with no cell phone signal and no internet!!! I will be back on everyday , sometime around or just after Thanksgiving . A little bit early , but , Happy Thanksgiving To everyone on this Geotech Forum !!! Take Care everyone !!!! ..........Eugene52 / formerly Amtech2005/stalni-clan of Ivconics Hobi-Detektori

Hi Eugene,

So you could find a place without net and cellphones? this still exist on Earth ?!! Cool !
Good luck !,
Fred.

Hi,

Hi,
Can this tesoro be made with diode indication for detection?
I mean when there is a target the light on.This might be usefull.

Hi

Hi,
Ivica.
I now that you have a lot of work and also you are on other project but Please help here.
I have made a progress with my TGSL 1265.Buy changing some caps.But still havent recived my pair of LM308 and just for tests 081 but this make a diferance as you now.So I get a prety good responce and loud sound but I have proceeded to change caps and now the sound is broken.Damn.From a begining again.
I will make a picture with the TRs voltages so you can help.I suspect something there.
Also can you tell me where to conect the - point from monostable?To -8V or GND?
I have tryed TLC271 insteed of LM308 but no good.
Thanks
