Hi all I am one of those lucky ones that picked up a circuit board off Carl after designing the PI detector, - I say this 'cause it's been a fanstatic project for me from start to finish and has tought me heeps about the hobby.
although the construction artical is not yet finished ( I know your busy Carl ) I assembled it and set everything to mid range from the text on Carls web Page and off I went, very excited, to have my new toy. I made a perspex box for the detector and used 8 AA batteries.
Although I have to date only found nails and rusty bits of nails...LOL I was very supprised with the depth and the hardness of the ground here in Oz (I hate digging!!)
Tommorow I will try it on the beach for this is the purpose I decided to build it.. I have a few coins that I have drilled small holes in and attached string too (Just incase!) these I will use to test it and try to fine tune.
One thing I would like is a headphone Jack, I think it would increase the sensativity a bit...Any chance of a MOD, Carl??
