TESORO GOLDEN SABRE

Nice work!
What is the weight of the coil by itself, and the whole unit?
Would like to see a vid of it in operation.

got it, thanks anyway.. turns out the -12v wire was nearly spoilt.. heres a picture of my finished tgsl.. thanks to veryone for help especially to fabian for the small pcb design.

Yes. Mine turned out to be a bad solder joint. You may have a dead channel, but no way of knowing without chasing it down with a scope. Maybe start by looking at your disc channel?

im in a bit of confusion here.. ive made another tgsl edu fist one works ok, the 2nd basically ok but it doesnt reject iron, and it makes sound when coil wires is touch., anybody got same experience before?

[sukri01]

haha... lack of sleep finishing this board makes my see crazy things.. its actually approximately 34 cm , sure, ill post some picture when i finish with the detector stem.,

Glad sukri01. For me it was also more comfortable that size, that is the only difference with the design of Eduardo. On the other hand, I finally never tried with the two tones, despite having the board ready, with all components in place ...
Good luck with your project and if you can, post some pictures in the forum.

regards,

Fabian

PS: 31"? Are you sure?

Yes. Simply remove a turn from one of the coils and use this as the adjustable loop.

or place a small piece of foil somewhere at the overlap gap to influence the null procedure while looking on your multimeter you will find the right places

hi fabian, ive made it, and it works perfectly. the small size is just perfect. truth is i never made my edu works before.. i dont remember from which post i got it from.. but yours works on the first time.. just great.. for 2.5 cm coin it could detect at about 31".. now ill try the add on card for 2 tone. need to make smaller enclosure for the board too.... thanks again..

[sukri01]

thanks fabian.. ill try it.. and post the results here..

TGSL Edu small

Sukri01 asked me about a PCB for TGSL Edu I did a while, and I noticed that I had never posted. Here it is. Is the original design of Eduardo, only a little smaller and it works.

On some Ive tipped the resin in and observed it change. You can push one of the coil bundles thru the resin with a lolly stick to retune a little. Keep the phase, rather than tiny null. S

thanks der_fisherman and qiozhi.. ill try both method. that adjustbale loop comes from one of the coil wires yes?
