hi mr francoi . i have a question??
what version is the best for biuld??
1 led or 3 led?
i read many page but i confused
thanks a lot

[FrancoItaly]

No doubt, with more leds you have more precision to determine the target's position, since approaching the target the signal increases until it disappears on the vertical of the target.

ok.so i use and build the shematic in page 1 ??
thanks a lot

[FrancoItaly]

the schematic for power stage is in "Power display stage (1 led)" and the display stage is in
"displayStage(3 led)".

How we regulate it if it goes north ;

[FrancoItaly]

I don't understand what you mean, if vou mean the compass effect, you must reduce the DC gain.

[stergeol]

Yes the compass effect .. DC gain in TR5 transistor ;

[abdou2014]

the DC Gain in display stage , P2 and R2 .

Has anyone succeeded?

Hello there

Excuse me friends. Is this CD4046 PCB "working" or not ? I've tried this part overlay with no luck.
Are the parts in the right order or not ? If it's working which is the pin or part that I can take an output for LM3917 VU meter ?

Thanks in advance !

[FrancoItaly]

I have not tried this PCB so I can not give any judgments. My advice is to make the sensor stage on a separate PCB and fine-tune it. Then you can add the other stages. I attach here the original PCB I used in all models and I suggest to make it double-faced, with the bottom face attached to the ground. This prevents oscillations.

Best Regards

Thank you Franco for your time plus your work!!
