when I see it the TGSL-EDU version haven't ground potmeter? (just: sens, disc, and all metal switch)

Found my TGSL-EDU picture, Ground pot is pcb pot (bottom left) - you can replace it of course with external pot

Not a problem at all. Just go for it and don't bother much about tolerances - you are not working on treadmill and no one is going to judge you. If you miss by + or - 50% no big deal. In worst case scenario you'll compensate it using different values of capacitors.

Just go for it

Thank You!

If I understand correctly, only show quasi an approximate result (+ - 50%)!?

I tried again, and it came out: 8.753 mH...

Hi!

I have tested the coil calculator with this datas:

RX

inner radius 126 mm
wire: 0.25 mm
number of turns: 107

And I get: 6.035 mH

but in TGSL_101 _PART1_pdf I see 6.5 mH

Why is it different? This coil calculator ideal just for mono "O" coil (DON'T DD coil?), or, I made a mistake?

Please, clear up this problem!

that may depend on the particluar board version you are using
I have this layout, it may help

THX Silverdog, I try it!

Hi!

Please someone post it a picture how to wire the switches to PCB?
(I dont find it, because there is a lot of TGSL topic, whit lot of page... )

I have uploaded my latest revision of the TGSL_101 document here. I have always felt that it was lacking some material under the "induction balance concepts" section. Hopefully, it will help clarify some points to new builders and add some flow to the document.

Also, several other members caught a few errors and they have been fixed as well.. in particular, what to expect while making nulling measurements.


Thanks!
Don

Thanks Don!
