hi to all freinds
After a long wait, I acquired a Black Hunter device and prepared to reverse engineer.After opening the box, I was faced with a world of resin and epoxy that made access to the circuits impossible for me.However, since my friend insisted on reverse engineering this device, we decided to remove the epoxies. Unfortunately, this work caused damage to Black Hunter, but we obtained some information from it, which I share here. The heart of the Black Hunter device consists of a board Raspberry Pi and arduino deu. The device is powered by 16lithium ion 3300 mAh batteries.In addition to the lithium battery protector, a separate set of charger circuits has been designed for this device, which is located under the upper panel I will post photos of equipment and internal circuits for all friends. If anyone can think of a way to remove the epoxy and gain access to the circuitry please advise so we can completely reverse engineer this device and post it here and discuss it.The reinforcing parts of the device are completely buried in epoxy and are inaccessible

Maybe Carl can help you.

There is such a thing called Dimexide. Apply carefully with a brush and remove the resin layer by layer. If you don?t mind plastic, then fill it completely. Epoxy resin deteriorates quite well, plastic and paint deteriorate.Forgot to add. Do all actions under a hood.

why you want reverse engineering it?
it is digitally controlled oscillator . commercial trick !!!!!! also with variable amplitude . there are some other circuits seem it. i did try lords with oscillator ... didn't work as a long range . |

My dear friend, I have worked with many detector circuits, but I believe the Black Hunter was one of those long-range detectors that I was able to get good results from. I tried it on 5 unannounced buried targets and 4 points were good It revealed easily. In my opinion, Blackhunter is a different device than a digital oscillator and it can be used well for an exploration.I've reverse engineered a lot of circuits but none were resin sealed as hard as the Black Hunter.If I can reverse engineer the Blackhunter amplifier circuits, I will definitely share the information in this thread Of course, with this amount of resin, it is a little far from the antar.

was interesting ... are you did measure output frequency and amplitude for silver and gold ? what was shape of wave ? |
