mine sweeper from madlab

[nick holas]

hi all,
what do you think about this metal detector ?
perhaps for pin pointing, i ve done it but can t have any detection whit coil?
some one have an idea

thanks

May interrest

beware my project don't work (perhaps my routing???)

I could not find the source code for the PIC.

I could not find the source code for the PIC.

It looks like you have to buy the kit from MadLabs in order to get the source code.

hi all
i think too, only hex code free , they send it to me, i just answer it.pretty isnt it?
can you confirm me that the pcb is well routed please.

hello
has someone tested the minesweeper
the madlab sites for the minesweeper show some cool working modes

[nick holas]

hi bernt ,
i ve done it again on another board but it don t works again .i m sure it is my coil.
if you want to try , perhaps you will have better chance than me.

hello nick

only problem is the microcontroller
no source here
best choice seems to be ebay from china
the code i had already from you i think

coil with 10microH cant be right? the origianl use a pcb coil from what i see maybe only some couples of windings with very thin copper tracks

[nick holas]

hi berntfind my micro at conrad or selectronic in france (best price selectronic) perhaps reichelt for you (saw good prices).
for coil haven t done it with pcb (haven t got any more), done it with ferrite rod and air core .
if you do it tell me if its good or not.
thanks

Hi Bernt
You buy one kit!!! It s super!!!!!!
Did you solder it?
How about it?
Have lot of question!!!
I have compiléd asm in hex but don t put a Hand on m'y oooooold prototype!!!! So i can t test it!! Grrrrr! (If you want this file??)
Finaly i can ride my bike,only the same great pleasure!!!!
Thanks a lot

Hi all
Hi Bernt
Nice video
Coool!!!!!! But not very strong!!
But it might be modded? No?
Perhaps with ne5534,mcp602 etc.....??

if i look into code it seems like bfo or so

if think anothe coil and better caps at tx can make some changes
but not the big hit

this unit isn´t a pi detector

at moment i dont make thoughts about the working principle
just happy it works
