- Power Source: Standard 9-Volt batteries for the detector circuit and detonator. The watch operates on its internal battery.
- Anti-Tamper Features: None
- Watch Type: Casio F-91W, but other digital alarm watches could be utilized.
- Size: The printed circuit board measures 67mm x 62mm (2.6" x 2.4") with a maximum assembly thickness of 19.5 mm (0.8").
- PC Board Substrate: Perforated, single-sided epoxy-fiber-glass experimenter board.
