Whadda WSG110 Hot Wire Version: Assembly kit 9 V

With this skill game you can test whether you have a quiet hand. The oscillator used in the kit has a very high frequency of about 3kHz (3000 cycles per second). Move the ring along the bent wire without touching it. As soon as you touch the wire, the buzzer sounds! The variable resistor allows you to change the pitch.
