Some stud finders use capacitance to locate wooden studs behind drywall, based on the difference between the dielectric constant of air and wood.
I'm wondering if a Teensy could be made into a stud finder by adding an antenna and a small piezoelectric speaker to play a tone with pitch proportional to touchRead().
It's possible to purchase a commercial stud finder for less than the price of a Teensy LC, so this would be more of a learning project than a practical one, but I've got the parts on hands, so I'm wondering if anyone else has ideas or references.
