Super TGSL With H Bridge TX Diff RX Quad Sampling

[Mike]

I could throw in some multi-frequency tricks to make it all even more interesting.

That would be very interesting, indeed I'm not sure I've seen any multi-frequency IB/TR projects anywhere.

My day job and my family obligations will surely slow my pace, but I'll get there.

Real life has to come first of course, but it's great to know this project is still ticking over. Thank you

Hi
What information the coil rx and tx the awg and circle's radius and turns the shield to rx and tx??? Please answer thanks for all

Hi
Use the same as for TGSL.
0.25mm-0.30mm Cu wire for coils. Please read the TGSL topic there is everything you need!

Copper Wire Diameter 0.30mm Rx = 107 turns Tx = 98 turns What is the diameter of the coil 27 cm? And a tin shield for each to rx and tx thank u sorry for my English so bad

Hello, I liked the project, I would like to collect, who already uses this metal detector and what impressions? As for the winding of coils, on some page I saw data on the number of turns: Tx-45, RX-280 rolls (what wire diameter?). The small question is: the transmitting coil is 12.5 kHz, the frequency of the receiving coil is the same, or there is a frequency difference.

Judging by the silence in the subject, she "fell" irrevocably, and it's a pity, I wanted to repeat this device. All the same, can anyone answer the question: is it a two-tone device? Somewhere I watched the video of the work, I liked it very much, but I can not again find this video, skinte please link. Thanks

Detector on video is http://www.geotech1.com/forums/showt...php?17861-IGSL

I am not sure if audio in schematics is single tone or some kind of VCO...
