BARACUDA-Legend-1

[bernte_one]

detection range is ok for you coil
but normally you dont need the fine tuninh delay pot
use a multiturn pot or multiturn trimmer
so you can fine adjust easy

Hi Grant
great news i have got one of your boards to work
after fixing the solder blob
i could not figure out what was dragging down the -5 volt rail
turned out the 40106 chip was doing some weird things to the
-5 volt rail , replaced it and it now working
now i need to make you a new coil

Excellent, thank you for all your efforts it is greatly appreciated.

Tried something different. I replaced the NE5534 with a LT1115 that I happened to have around and noticed a nice depth increase, especially on gold objects. Cuda also ran smoother and quietier. Anybody else try this?

[plumabob]

Thanks for getting back. I wanted a comparison with my homemade 12 inch mono and I'm right there with yours on the air testing. I will try swapping out the R1 when I get a chance to see if there is any improvement.

Regards,

Bob

The detection depths (air test) with an 11 inch commander coil;

mens gold wedding ring - 30cm
50 u.s. cents - 20cm
5 aus. dollar gold coin (1/20 ounce) - 18cm
1 dollar coin - 27cm
50 aus. cents - 34cm
20 aus. cents - 31 cm
5 aus. cents - 22cm
1 euro coin - 30cm
50 euro cents - 26cm

I have experimented with resisitor R1 and found that a 680 ohm resistor worked quite well.
