This simple circuit provides the electronic buzzer part of a Buzz Wire Loop, Steady Hand, Reaction Tester or Stress Meter game as it is variously known. The board uses a multivibrator circuit to drive the small loudspeaker included.
The idea is old and well known to most people. There is an irregularly shaped wire connected to one end of a circuit and a small metal ring, attached to a handle, which is connected electrically to the other end of a circuit. The wire passes through the hole of the ring.
The player must move the ring along the full length of the irregularly shaped wire loop without touching it otherwise the buzzer will sound immediately and they have failed the test. The circuit has a turn off delay so the buzzer will sound for a time even after contact is broken so no cheating. Wire loop, ring, handle, battery, enclosure, etc. not included.
Ideal game for fetes and fares. Board can also be used as a buzzer in alarms and warning systems. Kit includes solder for assembly.
