BARACUDA-Legend-1

[Guzzi]

Used 2 CD 40106 and both stoped working after a while. HEF 40106 stil works. Accidental? The datsheet gives no decisive answer.

#616 is SMD

Thanks', I will use the normal board then..

Ok, a bit confused here
I'm really interested in this great project, but which layout should I use to etch the pcb, the one provided by ApBerg at post #49, or the one at post #616 (hispalba's)? or another?
It seems that I didn't understand the differences!

You can use a free sprint layout viewer that also allows you printing http://www.abacom-online.de/uk/html/sprint-layout.html

Thanks, it was exactly what i needed.

Next question: what is the latest schematic of the Baracuda?

[Davor]

No. I use only a viewer for the time being. My PCB layout skills are still back in '99 when I last did it.

Davor, Have you tried the Sprint Layout Program.
I just ordered it today.

Thank you for the answer, I know the pcb from Silverdog is exelent but i like to build a smd version. The smd version in BARA.ZIP is in Sprint layout that i do not own.

Hi Guzzi,

I agree with Qiaozhi, I have build Silverdogs Barracuda kit you can't beat the price! The kit comes with everything you need (except the coil) to make this high quality simple detector. My barracuda works like a charm and I use it all the time. Trust me,You will not be disappointed.

Best regards,

Hello All

I like to build The Barauda smd. I do not have Sprint layout, does somebody have a layout in a free pcb program?

Leendert

A simpler solution would be to buy a Barracuda PCB from here ->

i dont want more inductivity so should i place a resistor 1ohm or 2ohm at least 1W in serie to coil
or can i do it another way

regards

You can try with aluminium wire.

hello
some days before i build next baracuda
i tried a coil with around 100microH und under 1,5R
wire is massive core 0,8mm with isolation 1,4mm outer dia
after a while irf 9640 gets hot
but performance is very good with that coil (fast target response)

how can i solve the problem with irf 9640
i dont want more inductivity so should i place a resistor 1ohm or 2ohm at least 1W in serie to coil
or can i do it another way

Could be FET Q5 in motion/non-motion circuitry. It may have Vgso quite high so it leaks. Just replace it with BF245A or B.

BF245C is great for Q5 = motion/non-motion circuitry.
Best regards.
