Most old circuits on that website in India don't work.guigocase said:did someone tried that ci4-clap diagram?
i did and it doesn't turn the load on...
i clap once and the red light goes on but when i clap twice nothing happens...
what am i doing wrong?
Can someone help me?
The LM324 quad opamp is one of the noisiest ever made. Use a better quad opamp and it will plug in and work much better.prad123rita said:1. There is a lot of noise in the circuit, can I use another latest OP-amp TL074 or OPA 4134 to improve distortion and Noise. Do I need to make any changes to the circuit. All units are quad.
It is a precision rectifier with a gain of 101.3. what does IC1B do?
Its output is a timed positive pulse.4 what does IC1D do?
I don't know. The project should say why the gain is switched.5. There is a GAIN input to the transistor base. What is the purpose of this?
A hand clap is sound. Music is also sound. The hand clap circuit already has a highpass filter so adding a bandpass filter will just pass the frequency band of music that is the same frequency as a hand clap. Then the music will activate the circuit the same as a hand clap.I want to put my clap switch in my room where there is a lot of noises such as music so I want to add a band pass filter. The question is where do I add him and do I need to add an amp as well?
It will be difficult for a circuit to ignore loud music but be activated by a hand clap without the circuit having a brain (a computer that remembers what a clap sounds like).how will i make my switch work only on the sound of a clap supposing i want to put it in my room where i usually play loud music?
