BARACUDA-Legend-1

is this board is working does it have errors ? anyone test it yet ?

where you did buy the pcb from? i must say this guy to stop the troublemakers' production.

Please read the information in the link, and particularly the Build Document. The answers to your questions are there.

uff... this Apberg board is spinning by boomerang in the sky and that seems never been murdered...

sorry, i have not relation to 'geotech' version of the board. i am/can answering just of my version of BARRACUDA LEGEND +.

pleasure

He's not referring to either your PCB or the Geotech version. He has the the original Apberg board.

Dominator69 - There are several problems with the Apberg board that were corrected in the Geotech version. Please read the full story here, and in particular read the Build Document -> Geotech Baracuda - REV-A - Project Details

On my 1st photo the circles are one of them switch ?

[kt315]

the switch is left just on mine board. on geotech board it deleted.

[Dominator69]

Where is on the board on/off switch does it work without it ? Also is I got 4700nf 25V is this ok or i have to put 16V ?

[kt315]

alkaline ok. accubatts 1.3V 8pcs AA gives 10.4V.

[Dominator69]

Thank you then 6 batteries with 1.5v AA is that ok

[kt315]

9V batt LR22 typo does not work with PI detectors. lowest current given. your longest trip in electronics... just began...

Hi to all, i bought this pcb 5 yrs. ago and i finaly soldered i have some questions if i did it correctly am i missing something on the photo you will see that i made circles on it. I seen on some other photos they put switch and something else can someone help me with the board . I didnt test it yet i need conector for 9v battery also to solder the speaker on it. Thanks in advance

Hi to all

I built geotech barracuda rev a

according to mr qiaozhi said: the detector can sens a coin from 28 to 30 cm but in mimnimum sample delay and with minimum of pick sound
also the detector is perfect on sensing nonferrous metals like copper but maximum depth of detection for a 15 ? 15 cm copper sheet with 40 cm coil is about 50 cm and maximum depth of detection with this coil is 80 to 90 cm for 50 * 50 cm metal objects
Also you can increase depth of detection by changing tx pulse width
for this purpose i replace the c5 by capacitor 15 nf and as a result tx pulse width increase to 150 us and frequency decreaces to about 300 hz
Also with this changes you have to increase r4 to 2.5k
and in my opinion you should increase damping resistor to 470 ohm and a little change on resistance of coil with series resistor 1R

Regards

Hi seller
I have bought your bare board for the barracuda detector

I am not any good at electronics but was hoping to have someone build it for me do you know of somebody to do this project and what it might cost and where to get the other parts?

Thank you
----

a buyer asked me in PM. who can help this collegue in United States to build bara on mine board?

sincerely yours
