Assembled and boxed Clone PI AVR metal detector

Some more photos of boxed Clone PI AVR metal detector and self made coil.

I have made a coil from Ethernet cable between two round plywood sheets filled with Makroflex sealant. More about making coil from Ethernet cable can be fount here. Idea how to seal everything came from here.

Clone PI AVR intself was boxed in a box I bought in local electronics store. I decided to add a switch to switch off external beeper so that sound will be provided only through headphone socket. For the coil connector I have selected some two pin microphone connector. I think in general it came up pretty well.

Will be mounting everything on appropriately bent and painted PVC pipe. Will post pictures later. Some day. Probably.

    1. Will have to look it up, but I would say it was pF
      where it is like 420 its pF
      where it is polarised 0.1 or 1000, its uF
