Arduino Gaydar
Recent studies have shown that genders have differing electrical resistive properties that may allow for a measurable acuity of sexuality. This, is in no way true. But, the average Joe, does not know this. Thusly, we have hacked an Arduino Uno (or Micro) to provide no real information at the user's discretion.


Upon activation, the Arduino Gaydar calibrates, then enters a scan mode. The protruding antenna contains a capacitive sensor that adjusts a servo relative to electrical resistance. Vaguely protruding from below the housing (see video) is another capacitive sensor that differs the servo's mapped variable. Upon prank, the user may decide the homosexuality of any person being scanned, but when turned on the user by an unknowing third party, the heterosexuality is assured.
