IGSL

[ivconic]

Hello

Ivconic good hunting, beautiful coin IGLS good results.

Have tried both versions?

Hunting with speaker or headphones?

Level of sensitivity in the search?

No, only last version with Minelab TS1000 coil.
NF Sens at maximum, F Sens at half, NF Disc at zero and F Disc at zero.

To Amalio and Jerry;
no, i haven't used earphones - just internal speaker (maybe that's why i don't like it's faint audio?)
I don't like earphones and almost never using them. Especially from last year when i had hard ear injury. Now is not advisable to me to use earphones anyway.
Maybe that's why i am not so happy with it's audio?
Because, i noticed; both friends with both Vaquero's (2 of those were yesterday: one "USA" and one "Germania") are strictly using earphones, always!

[ivconic]

Is that cool? Or What?

Do you know what it is?

It's Serbian medieval silver coin, "Milutin" or "Stefan Uros II".

But... there is always one "but". I still don't like mum and faint audio response, typical for later TGSL....
Audio is good and clear, no problems with it.. but it is mum and faint much more than i wanted in situations where deep coin was detected.
No chances such coin to miss - but i would be more happy if IGSL was a bit more "concrete" ....let's say as "nervous" XP or a bit less "nervous" Musketeer....
....
I am considering chances now to upgrade it's audio more..
And also there is another thing that can be done:

Just curious if this was using the built in speaker or with headphones?

It sounds like you have the IGSL designed well. It has been 2 months and a couple weeks since your very first post on the subject and here we are already with a beautiful working detector. Congratulations! That is such an incentive for the rest of us and a worthwhile project.

From yesterday...
IGSL's THE VERY FIRST real find...

[ivconic]

Yesterday i spent whole day outdoor with IGSL. Detected and dug dozen roman coins and one medieval Serbian silver coin.
Stability is good.
Everything else is working just nice.
Huge advantage at IGSL can be the fact that it is no more possible to mix large irons with colored metals in soil!
A friend went out with nice Tesoro Vaquero and we had couple situations where he invited me to check the spot he previously detected.
Vaquero indicated that signal as "colored" metal - while IGSL clearly indicate it as plain Iron..!
After digging and recovering the target it showed that IGSL was right!
....
All day long checks and tests proved to me IGSL is really usable and good machine.

And also there is another thing that can be done:

The other day Carl explained something about mixed mode audio...
I am considering chances to rearrange IGSL for mixed mode audio...



However, IGSL ,as it is now, is so good that i can be only very satisfied and nothing else...
Further adaptations will only improve it more and more...

I could see they might be delicate. I use the dfbowers "glue pot coating" method which drags the wire through a varnish as it is wound. It makes a pretty tough bundle that might survive flatness if you let it dry sufficiently. The hard part is trying to keep it from sticking to the form. Maybe there is a way to lay paper on each side of the form, and just let the paper stick to the coil and provide support (cut away excess later).

Hi Simon
I use paper glue like we used when we were kids, its just sticky enough to be able to get the drums apart without the mess, once dryed it leaves know traces anywhere on the upper lwr drums, all you need to do every so often is wipe with a damp cloth.
The only tip I can give when using this method is put plenty on because its 95% water so its almost not sticky to touch, but just enough to hold them blessed coils together lol.
Once the top drum is off all you do is ease the coil further up the guides, bits of paper underneath the coil, then varnish whilst still on the former.
previous to that I was varnishing as alot here do direct onto the wire as it was winding, awhich gave me too fold problems, one was the mess to clear up each times which often included sanding which was wearing my guides down, the stink in my workshop, but more inportantly i was gambling with buggering up the coil while trying to get it off the form where it stuck so ridged to the guides, at the very least either fracturing the insulation, or worst like i did breaking a winding, which made me then try less agresive ways to the matter.
Give it a try and you will be well impressed.
All the best
Dave

To all over you who are talking about Schematics and PCB design, firstly many thanks for your input, that is exactly what we need.
Simon had a good idea that sadly Express appear to only ignore, as its an excellent idea.
What about if we make a list of what we want in a package? Then compare each package and see which one fits our needs best of all......sadly Eagle cannot import a picture, but that is about the only real limitation, otherwise it does just about anything you could possibly need - and a lot more!!

Regards

Andy

I agree with fisherman 100% on this one. Another possibility is Designspark PCB with Schematic design.

I was just going to suggest that.

It's based on EasyPC.
