Batteries

Hi

Hello,
Max how are you?
I have tryed several ways and still have this Batt prob. but will resolve it soon.
Greetings

Hi,
Max.
Thanks man I will try today and post the results.
Buy the way is this led diode flashing when circuit is with no load?

Beacause on my its flashing?Whats the point?Should stop flashing when battery is full charged?

Hi,no it stays always on... to say... that there's voltage there.Just this. You can also exclude it if not useful to you.Kind regards,Max

Hi,
Man.I dont wanna be rud because you have help me to,but I were talking with Max here ..........................
He and Ivconic help to beginers understand those litle secrets.Isn't this forums allabout?
If I can buy such will I waiste their time?
Or you think that I am an idiot?
This worth here 25 Euro I cant afort it now!And why should I when with some help I can make my own even better one!
Give a man a fish and he wont be hungry any more,TEACH a man how to cach fish and he wont be hungry any more.......right?

Hi,

C'mon tiktak take it easy...Qiaozhi never told you such things...don't be rude !

I think maybe he just was bored of this thread of batteries... anyway... coming back to your problem...

"I have found another ac/dc adaptor but its current is 1000mA!
Isn't this too much?
Will this circuit sucseed limitimng gurent to the proer value for 1,4Ah 12V battey?"

Yes will be good as power supply... and yes the circuit will limit the current at right value for a 1,4Ah 12V battery. So use it.

I have similar stuff and works absolutely COOL.

Kind regards,
Max

My goodness man ...

You first started having this battery problem back in July 2007!!
Wouldn't it just have been easier to buy a proper battery charger?
They're very inexpensive.

HI,
MAX!
HAPPY NEW YEAR!!
How are you?Did you have a nice new year party?

I saw that you also looked Leto's good work.
What do you think have you ever tryed rebek?

Thanks see you soon.

Hi,
yes was nice party...

Leto's work is nice... I haven't tryed it yet... (name is rebek?) but could be interesting. Now I'm involved in some other things... but who knows... with a little more spare time maybe I'll try it.

Kind regards,
Max

Hi,
Max.
Thanks!This wrds mean much for me!
I will enjoy for shore!
I wont be able to use internet next couple of days thats why I wish you a happy and helthy new YEAR.I hope next year be more reacher on finds for all of us!
Thanks MAX


p.s.What cheme should I try for deep seeking?Twin loop?Hamerhead?Some PI?
Have you make one of those?

Hi,
thanks... same do I ... I mean enjoying my wonderful TGS.

I've made so far... anything ???

I mean I've made all of these types... made a lot of PIs (don't remember exactly how many of them) and 5/6 2boxes I think.
Made also BFOs and other kind of VLFs... anyway...

I've made Delta, Stuart's and many others...

back to the question: twinloop ? NO avoid it it's old and buggy project.

Hammerhead is good to understand PIs... I suggest it if you wanna make a PI cause Delta and others have few documentation... just posts and there are also errors on some schematics. With HH you'll understand lot of things about PIs.

I can suggest you also some Stuart's PI for same reasons...but there are also errors on it. Old ones like sandbanks are too obsolete now.

If you wanna make sensitive PIs you have to make e.g. Delta and modify them for your needs. Also pulsdetektor's projects are really nice... but you have to understand language cause all website is in german.

I think inland search with PI is good just with large coils of 1mx1m dimension minimum...and suspended at 20-30 from soil...other smaller coils you can use just on the beach cause of too many falses in inland conditions (maybe 80% of inland places you cannot use them).

Then you can also make some 2boxes for depth ... but consider you need big mass to really detect something with them... they don't detect single coins (99.9% of them I mean).

Or you can focus on magnetometers too... but for iron boxed treasures only or ship wrecks location.

Kind regards and happy new year,
Max

Hi,
Max.
I am glad to tell you that my TGS is working good now!
Thanks to you and Ivconic.
I have tested in air and I get around 25-27 cm for 10 euro cent coin in air and disc mode.
If I buy this osciloscope will I gain more depth because of the accurate nulling?
Is it worth to buy this one for 45euro?
I saw some multimeters that have frequency and I think that they have 4mV/div?Or it were 4mvpk-pk?I dont understand from this!!The frequency of TGS should be 14Khz?So multimeter should have unless 20 khz tolerance?
Thanks
Will try some depth test and will keep you in tuch.

Hi,
to measure frequency you can use also a multimeter... with frequency counter e.g. 20KHz range. But for phase and to see signals vs time you need the scope. If you are satisfied by your TGS now you can also skip the scope expense.
But if you wanna try extreme nulling and sensitivity settings you need one.

I think that the 45eur one will be good to see signals and get a good null on RX but sure is not good to read other sensitive informations like phase angles: I mean you can read them but a too limited bandwidth will make you crazy about results on such kind of accurate readings.

You can also buy some cheap portable digital scope for good price ... that will provide you directly e.g. phase values of signals or direct reading of e.g. frequency on the screen but good ones start from 250-300eur so are a bit expensive.

Anyway... you can relax now and think at these aspects and evaluate...take your time to make decision: your TGS works cool now.

Kind regards,
Max

Hi,
Max!
So,this mean that I havent damaged my sells?
I will go to search for more powerfull ac/dc addapther.!
Whats the differance when charging 10 NI-MH pack and 12V 1,4Ah battery with this charger?What should I change between the two sets?
I have to tell you that when I write to you last time before two days I just went back from this fortrres that I were hearing many noises there and this were the only one sunny day lately.So the tempereature just reach +.
And there were a lot of snow on the one side but on the hill there were a small area where the snow were gone and I stert dtecting there.When I thune geb just quick I start searching and I found a small copper coin.I think its roman.Very damaged but still seeable on some spots.Just this small coin for 1 hour but.......man this is my first one!!!!Its mean much for me!
So TGS is very good afther all.This coin were just under the leaves on 3 cm.Yestherday I go there again but the temperathures were under the 0 all day and I were not able to penetrate couse of the verey hard frosen ground.
Yes,I told you that I have found modern stuffs on my second test.
But I never find ancient coin till now!
With what did yu clean your find/coins without damaging the good green stuff?
I have noticed that when I turn the disc knob at 3,5 from 5 I get a lot of noises!Expecialy when I am on rocks mostly.But maybe this is from the - temperathures!

I will ask the man about this scope and will tell you about other datas.
Thanks

Hi,
nice to hear you found your first coin !
About cleaning ... sometimes is useful putting the stuff like copper under some mineral oil (or kerosene) and wait some days or a week... then after you can remove some dirt and oxide by a common brush. Remember not to use metallic brush or other emery stuff to polish good items.

Sometimes oxide patina will crack and leave the item without damaging too much the reliefs: that's what you'll hope happens after oil bath.

There are also chemical stuff prepared for that kind of work but I don't know names of widely available commercial products.

There are also electrochemical ways... but are for true experts... cause you can make big mess with them.

Circuit you made is good for gel-type cells, and I think you didn't damaged them with lower current/voltage.

For NiMh cells you need similar circuit but more care on current limitation than voltage at output (so you can use the other simpler circuit for them).

Best regards,
Max
