PICKINI V4 - an easy to build, self adjusting PI detector

[JdaleH]

Does anyone have an ExpressPCB layout? I would appreciate an ExpressPCB file, even if incomplete. Thanks, Dale

In using 2n7000, you can apply it ! Pls check the position of leads !

Hi Friends,


Im testing this configuration and




1)to conect a led


After c15




--capacitor(c15)---resistor(1k)--diode(1n414--led---to ground




2)To conect a speaker and Fhone





.............................................|---Phone---500omhs---to ground
.............................................|jack key
--capacitor(c15)---resistor(100r)---(speaker 8R)----to ground
.............................................|
.............................................|---100nf---to ground

The LED in the film of Rodrigo is connected to the auido output.
And yes, you can use BC547B - no idea about 2N7000.

I understand that BC549B can be replaced with BC547B, or you can apply 2n7000 to this mosfet.?????

[popka-ru]

Thank you. now it will work. I will prepare for the assembly.

[popka-ru]

why does the light flash all the time, where is it connected to?

Hi Friends, Greetings from Brazil, follow my video from Pickini V4.

Also, the coupling elco on pin 12 for the audio signal is reverse polarized.
Looks like you have an old Arionas layout - before he fixed all the initial errors.

[BC547]

Yes, it looks OK now.

Have a look at Arionas' layout in post #200 in this thread/

The LM318 mask is upside down. The traces around it are OK.
Pin 8 and 9 of the PIC16F1824 should be shorted.

So?

and another question, are there any errors in this print?
