Voodoo Main Discussion

[surfdetector]

I just wanted to say thanks to George for his hard work on this project! I'll be ordering the book in my next Amazon order, and the boards in my next order from JLCPCB.

I did a series of build videos for the Voodoo project that might be of interest to you

Thank you for the link! I'll watch them all this week. I was able to build some Minipulse boards a few years ago (which still haven't found their way into a usable end item...), but videos would have helped streamline the process considerably. I have a couple other soldering projects to wrap up as I wait for the boards to arrive from JLCPCB.. Then I'll try to navigate the current state of parts availability and get started!

Hi All, Could someone please let me know where I can buy a VooDoo PCB, or should I send the design files to JLCPCB? Is Rev C the latest? Thank you.

The PCBs are usually in stock at -> https://diydetector.co.uk/store/index.php
but I think the online shop is currently closed for holidays.
Otherwise, you can send the Gerber files to JLCPCB.

I don't have +5V value in tp15 In tp14 I have -5V One question: can the lt1054 copy with 50 mA output be the reason? Or there is another reason like 78l05

Hello every body,how I can increase the depth of this system?please help me,thanks

[Hamed_snjd]

i have big problem with the system,it sense a ring in 5 cm..............please help me.

How I can increase the TX frequency?

Has anyone ever used this loop?
If you know the specifications of this loop, please tell me. Thank you

My problem was solved by programming the micro on the board itself
I failed to get the LT1054 to work with PICKIT2

You would need to re-write the software and use a 18bit ADC or more. Switched gain in 3dB steps might also be an idea.

You will need to give more details than that.
5cm is only 1.96 inches, so you've clearly made a construction error.

Did you build the detector in stages and test each one before moving onto the next step?

Hello
I want to build a voodoo metal detector, are all the parts I need
currently still available?

There are no exotic parts used in the Voodoo Project. All the components should be readily available.

thank you
