IGSL

[PaullyG]

Тhanks PaullyG, i will try it!

No worries, if you need support H.263 video (xvid/divx) with mp3 audio, you'll need to download 0.93, after which they dropped support for those formats. H.264 with AAC audio has essentially made the older formats obsolete, so unless you need to use the older formats for particular hardware it's better to use the newer ones.

If you need h.264 playback support, VLC Media Player will handle pretty much any modern audio or video format if you don't already use it. (It can transcode also, but handbrake is generally more straight forward to use.)

By inertion i downloaded 0.9.5 version. It is working fine. To much options! Those i can understand - i adjusted, others i left unchanged. First compression (with such adjusted options) gave me noticable better compressed file than Dr.DivX !!! Audio is better. Now higher audio pitch at IGSL is absolute clear without distortion, but lower audio pitch is still a bit distorted. Must be that i didn't adjusted audio options very well. But video is excellent now!
Yes VLC is on my obligatory list each time i prepare and install my working PC.

all versions are available!
I have all versions now!

Hello Ivconic and others!

Mine IGSL is finished too Finally!
Its working like charm! I dont know.... I like that high pitch tone!
Depth is great! 35cm+ with 2 euro coin.

Now big iron is giving some differences between coloured metals. With tgsl it was detected clean in disc... Bottle caps detected like good metals unfortunitely
Al foil - no sound at all...
BUT! I havent played much with controls yet so more exp will be posted! It GND balanced very easely though!



Thanks again for the great project Ivconic!

Bravo! Good news!
Also very clean and neat work!

Hi Ivconic
Is possible make a test like this video with IGSL?

10x!!

Yes it is possible. I don't have good camera, will have to wait my friend to visit me and bring good camera, than we will shot another video. No problem.

Making TGS/TGSL coils is pretty trivial and exhausting (expensive too) job for me lately. It is OK if man want to make one coil for own needs. But if somebody need more coils (like me) periodically, than it can be pretty annoying and time consuming. Not to mention fact, that no matter how good coil was made - it will always stay "hand made" with risk to be out of standards and norms (tough to make 200 identical coils in home made arrangement).
So i was thinking to modify IGSL for use with some standard commercial coil.
IGSL turned to be much better than i anticipated at the beginning, so i intend to make dozen more in the future.
But i want to void to make coils for it.
So... i was thinking to adapt it for use with some original coil. First came to my mind was my most favorite Minelab TS1000 coil! Best ever!
So.. today i made modifications at IGSL and adapted it to work with TS1000 (as well as with TS800 and similar coils for Musketeer).
IGSL is working splendid with TS1000! Depths are great, GEB also, Disc also. Stability too.
But what is craziest part - is working frequency: 8.5kHz !!!!
Completely out of any logic!! But it is working SPLENDID!
Only oscillator part changed and replaced with different one - nothing else changed on IGSL, not even 15nF at RX input!! So.. everything else is unchanged, only TX oscillator and output is different. Frequency is different (from 14.6kHz down to 8.5kHz) and performances are like never before!? Already made and tested. Already checked outdoor on real soil, today. So... i would really enjoy to hear comments from others - especially from those "simulator&spice lovers" here!

I will not post new schematic for now. I have some commercial plans and intentions with this now, so hopefully you will understand my reasons. But i can promise to post and share it later, in next few months, just as i sell few devices to cover my expenses and work that i involved so far. I am hoping that this is pretty fair? In meantime i would like to hear comments and suggestions!

Everything that is applied to IGSL so far - can be also applicable to TGS and TGSL, so .. i do know that there is huge auditorium for these matters here...

hello ivconic

i hope you make an info here in forum when you start to sell the modified igsl unit
so on i start to save some money - maybe my next christmas gift

good luck and success

I will not be able (nor i have such ambitions) to sell my hand made abroad, nor it would be some more serious production!
I just intend to keep it "secret" for a while, until i design another version.
It will be pretty short time until i share here current version.
Usually i don't talk in public in advance, like i did now. But this new modification is very funny and i couldn't resist - i simply had to say.
Best suggestion for you is to start making IGSL that is already presented here. Later you will easy rearrange, modify and apply new changes on it.
That will cost you even much less than to buy detector made by somebody else.

P.S.
Novak is simply THE BEST!

Your IGSL is nice indeed!

Using overlap, you get effectively 3 tones for three ranges - low, low + high, and high -- it should make hunting a lot easier.

Yes, that is correct. No more iron masking (like it is the case at TGSL). Now i can hear all the signals, some of those clear and some of those mixed - just like you pointed.

Very interesting about 8.5kHz working so well. I would think the DISC range might be reduced somewhat -- can you check it against a 14.5 kHz model? Also, have you tried increasing 15 nF to larger cap to see if it works even better?

Yes, i was confused too! Actually it was like this:
i removed previous TX from a pcb and put another, different one. I had no idea what would be TX LC tank values. I knew TX coil is 1mH (TS1000) but was to lazy at that very moment to calculate L. So i made pretty wild guess and put 0.33 (ooops! secret a bit revealed!!) and switched it ON. It started to work just SPLENDID from a start! It's a kind of luck and nothing else. Later i really did experimented with RX cap (15nF) to see if some more benefit can be gained.. but i had no progress. 15nF seems to be most proper choice again.
How is possible to work such good on 8.5kHz?? I don't have a clue, honestly speaking!
Audio pitch from 4024 divisions were to low so i simply picked another (higher) outputs...
And that was all....
