Hey,

Could gave PMed u But gonna post here. Auto correct almost failed there. Lol. I am thinking... Either reusing my old RS case and shaft, or buying something like an old non-working detector to reuse the case/shaft for. You can build your own PI. I can tweak the surf 1.2 a bit and get components from digikey or jameco. Know of a company that can make boards for hobby or test. Thinking to make a back up PI for under $100.
