Simple light sensitivity Metronome using 2N3904

This is Simple light sensitivity Metronome circuit. It use the transistor 2N3904 numbers and 2N3906 make to are origin frequency circuit. By the frequency in the sound from a loudspeaker will increase and is down. When lead light flasher come to near LDR within a darkroom. By resistance value of LDR be down when receive the light. Which will enhance the frequency of origin frequency sound circuit. By frequency change will continuously is like the wood keeps strokes the music there. The detail is other , see in the circuit.

Small Metronome using 2N3904

This is knock the melody. It uses begin flasher circuit in building sound click keen go up at a loudspeaker. But each time at Q2 (2N3906) work by origin frequency circuit that use RC and Q1(2N3904) ,R2 – 50K use fine work rate repeatedly through 20-280 sections time per minute. By value change of C1 (22uF) will change the tone of voice in the sound click at happens.

Transistor Organ by 2N4891

This simple circuit can provide hours of enjoyment as you learn tunes, play duets or just make some really weird sounds by pushing all the buttons at once. You have probably seen this ciruit before, it is fairly common. I have seen it in several books. The best thing about the circuit is that you can tune each individual note, or go to a whole new octive by changing one capacitor (C1). Because of this, it is possible to from an entire Transistor Organ ensemble. Why you would want to do this is anyone’s guess…
