Hi !!!

DCH85 is a static detector, not catch magnetic fields so it has n't stable properties.
It can detect an object from 30m today and another day from 3m or zero.
But if phenomenon is strong then it works for sure!!!

Hello

you gave info about:

OSCILLATOR CIRCUIT

RECEPTOR

BEEPER CIRCUIT

VOLTAGE REGULATOR CIRCUIT (no info)

are you sure this schematic is working ?

also if umidity is more than 85% the electrostatic locator not work very well...

One question, do you built this DCH of Folharin,is it a working project ?

I have work with it many years ago.
It is the basic schematic of Iconos or blue pistol from Esteban..... you remember.

hi Geo, you speak about the complete circuit with TDA or without ???

**Geo** · 10-15-2021, 04:16 PM

I speak for simple DCH85 without TDA (2 transistors input and 741)

**abdou2014** · 10-15-2021, 09:03 PM

Thanks, is the stimulator necessary ?

**Geo** · 10-16-2021, 05:21 PM

Yes...

**abdou2014** · 10-16-2021, 06:15 PM

Thanks , does this stimulator work well with DCH85 ???

Why you ask for the stimulator of DCH????

**abdou2014** · 10-17-2021, 03:51 PM

maybe it is weak and we need to change it

this is the PD I made. I'll post the rest based on the answers given. It's a bit cumbersome.

after some time I will post the pictures of my mineoro, not yet finished i speak about my new version , according to the mineoro photos of the forum, it is a regenerative ,
Mr Brain , is your pd work in the test field ?
