Surf PI Pro

[sdesic]

It is OK, ICL7660 is live and working in my first surf pi pro.
I will connect diode 1N5819 to guard it in future.
But I will loose -5V I will inspect all solder bridges.

Porkluvr, thank you for the warning.

I think I found my problem ...
L78L05 is my voltage regulator (with L)

>If adequate heat-sink is provided,they can deliver up to 100 mA output current.


>LM7805
>...each of these regulators can deliver up to 1.5 A of output current...

?Problem nuisance coil what when in the swing to the right or to the left there is always a false signal if the coil near the ground coil already use adhesive super glue so that it cannot move remains a false signal if the swinging right to the ground what surf 1.2 soil unsuitable for what is just to dive in the water

Do you have beep sound when you touch coil connector on your device?

liekwang

can you swing with slower speed without false signal ?
you can slowly touch ground with your coil without signal ?

?So what if I am holding a voice coil and coil if I touch the soil there is the sound of the voice however sensitive to other metals and gold ring him I think is very good in the air can reach 20 cm gold ring

Each coil touched to the ground there will be sound if I am swinging quickly a voice just like there is metal under what when I'm swinging right stick MD and coil hit the ground there will be sound by gently swinging the stick my voice is still there but is sensitive to metal mine in 20 cm of gold ring aerial sound enough to sound in the speakers

Try reversing leads to your coil inside your detector box.
Try connecting GND to outer shell of your cable to coil - check if it it already on GND and connect one lead from battery - to your metal connector directly.

What if I touched the body of ya there allumunium 9640 WE PATIENTLY WAIT for the body WE PATIENTLY WAIT for the sound will be heard and also what if I touch the socket from the coil to the box will beep if the MD MD I am less the ground

I don't understand your translation so I will repeat
connect minus wire of your battery to outer shell of your cable to coil and try again touching that connector or wire

[liekwang]

If I touched there could be sound 9640 WE PATIENTLY WAIT for bep

[liekwang]

I think MD surf is very sensitive to the ground but not yet I try on the beach is the same everytime I swinging fake signal what when on the beach

Looking for mods in coil size. Bigger... Smaller
What needs to be changed to connect 1m square coil if it is possible?
No problem with power consumption.

[sdesic]

And another mod is to other end of scale ...
using surf pi pro as pinpointer with coil diameter 1-2 cm
