Simple flower circuit

Posted on Mar 28, 2007

Circuit works: Rp1 ~ Rp13 scale resistance to the keyboard, but also the oscillator timing resistor, C2 is wide discharge capacitor, S1-S13, the key switch. Press S1 a S13 any one, such as pressing S1, the +6 V power supply

by Rp1, C2 and S1 to charge electricity. By charging initial C2 terminal voltage is zero, so the VT1 can not be turned on. At this time +6 V power source via R to provide a base bias VT2, VT2 conduction current through the VT2 of c, e pole flows through the speakers, and produce a higher voltage drop across the speaker.
