MELODY ORGAN 25 TONE
The FK244 mini organ circuit is an ideal classroom project for basic electronics, component values and frequency and musical scales. Tone selection is by stylus or conductive wand and conductive points on the PCB. An LM555 creates the 25 basic tones and a transistor oscillator provides a vibrato effect. All of the frequency-determining components are accessible for substitution in sound experiments and to achieve additional tone qualities. The kit is supplied with an 8 Ohm 0.25W speaker.
