I am building an all terrain robot based on a 12v dc system and micro atx pc board that is 10" x 12" using RC moster truck tires. It will be controlled via wireless networking and will send landscape images back to the controller PC. The posts here about metal detection have sparked my interest. What if my Rover bot was sitting on a rolex just below the soil and I never knew?
Can anyone recommend a small lightweight unit for around 100 dollars or preferably less that could be hacked? I saw some toys linked- I would like to use something capable of determining trash from precious metal, but I also am aware a top end detector is several hundred dollars and looks sort of hefty for my application. Does anyone know of a detector that already interfaces with a PC by usb or something? (one less thing to hack/code, hehe)
What about other sources- I hate scavenging new products for 10 bucks worth of circuitry and coil and junking the rest.
Perhaps I could get a replacement parts sheet for a well known detector and just order what I need?
I have seen little hobby kits that you construct yourself in the past but again those seem to fall under the toy catagory.
any input is greatly appreciated, this is something that I can develop and add to my bot over time and would certainly be useful and give another fun aspect ot the project.
if you see a guy in the park chasing a computer on wheels with a laptop and a shovel its me!
