Need more information and LM709 4 feet .7 pin voltage

Do you need a PCB?

Slightly deviated from the topic. Scheme itself is not very interesting. Interested in console. I mean the device with an arrow (which is on video). There are practical ideas?

Hi Yue Hailin.
Here is your circuit digram drawn with larger dots to be visible where has connection.
Pin 7 of US3 (LM741) and pin 7 of US5 (LM709) are connected to supply rail having increased (relative to battery) voltage. The increasing circuit is formed by US6 (ICL7660), D5, D6 and C17. The battery voltage 6V appears as intermediate supply voltage for US3 and US5.
For filtering of negative supply voltage, pin 4 of US3 and pin 4 of US5 are connected not direct to zero rail. The filter is formed by R30 and C21.

good schematics for my archive... a content of it is 1.53 Gb now... by the way... THANKS. look also Surf PI schematic that is identical to this your Polish.
look at this attached schematic too.

good luck

I have found PDF files. Inside a circuit board / But I want to copy it into the film.

if we count on the tested metals on movie, it does not seem that it is a powerful metal detector. it seems that it detect an ordinary coin at 10cm!

Who is Gary pulse. Single coil circuitry and PCB. I need more production tutorials / I need a simpler, the better

You ought'a get one of the Surf PI boards. Temporarily out of stock but should soon be available here:

It is not the simplest PI on earth, but almost.

If you haven't read Carl Moreland's Hammerhead PI article, read it.

[kt315]

the simplest PI is Tracker-PI. only 3 (THREE) IC packs:

1. ATMEL
2. TL074
3. CD4066

THAT"S ALL BUDDY WM6! beside maybe 78L05

good idea to commercialize the schema stamping them 'as swiitty batonchiki Snikkerrss on every mommy&dady day'!

This cannot be simpler (even single coil is not needed):
