C6894 - Gravity Detector Kit
This kit detects gravity? Well, not really - What it does do is remain in an off state until a curious person lifts up the kit to study it. The "Gravity Detector" has a CDS cell underneath the board which activates when the board is lifted and gives the "curiosity seeker" a mild electric shock from the "handle" attached to the board. A great practical joke item! Uses IC, SCR, and FET circuitry. Works on one 9V battery (not included). Size of PC board: 4" x 2".Complete with all parts, PC board and instructions. Skill Level 2.
