does anyone have a schematic for the head hunter pi
-
-
would like to see the board in high resolution. do not think it is more difficult than bara or surf.
people can do the pcb by sprint layout in one hour. -
hi kt...i dont know much about the head hunter but from what i learnt its one of eric's designs and good depth and uses two pp3 batteries which interests me very much to make a very light weight pulse machine for my wife..im not keen having electronics in headphones but prefer a normal box...i wonder which detector is the head hunter based on ??? the coil current must be very low just using two pp3 batteries.Originally posted by kt315 View PostComment

you had read a way i offered.
1. we wait broken/as-is/for repair detector on feepay.
2. you buy it. i pay a part of its price, but not much.
3. you do detailed pics of board inside, view on pots, wires montague.
4. you desolder board.
5. you send the board to me.
6. i get the board and do CAD files. i check the board and fix.
7. i order PCBs
8. i am back the board to you
9. you receive it and solder back
10. i get PCBs and do prototype
11. you get working detector and if need a board for its price.
12. everybody who paid for the detector a part will get PCB for its price. yes, it is crowdfunding.Comment

oh my teeth... i see Eric's board there and as i guessed its certainly his 'c-scope/goldscan SS' design. no more 'a secret of The Wizard of Oz'.Comment

its a very small compact design

i had wrote Eric does just two design in your life -
1. with 300uH coil
2. with 1mH coil
we see here 2 point. so its c-scope 6PI schematic.Comment

hi kt....i remeber some years ago seeing a photo of the c-scope 6pi...it looked very impressive....i would imagine the head hunter uses the 1mh coil cause of using two pp3 batteries as the coil would have 3 times the resistance.Comment

look on the photo of board. mosfet is irfd113 in DIP4 case. loving by Eric mosfet type. this is clear sign of c-scope 6pi and 1mH coil.
like the Eric's signature 'here was Eric'.
no secret here.

ive never used a irfd113 mosfet as always used TO 220 case type...i guess it makes sense Eric using a lower power type in the CS 6 pi and head hunter...maybe i will try and make a low power pulse detector over the winter and try and get it very light weight...most of the projects ive done apart from one have all been on the heavy side and arm killers
another c-scope model that really looked nice was the CS 7pi which i know is again one of Eric's designs...i wondered how it compared with the head hunter...i did an internet search on this model and nothing came up and i wonder why...was it not a popular detector or maybe very expensive ???Comment

It was a 1mh search coil. I had notes about it, can't find the file folder its buried in. Since it was a thru-the hole PCB, looked like it was easy enough to copy. Thought I took pictures of the one I had.Comment

i think Eric did a schematic, concept, but did not write a code. Eric is oldest school guards one good in analog but with zero level in asm.
ok. if with micro then we have cs 7pi.Comment

i think Eric's designs over the years so amazing...the ultimate being GS 5.Comment

And now?Comment
