When we use the bicycle(normal bike) at night. we used IC1 IC555 Oscillator signal is output to a lot LED super bright.
This is a circuit that features a running pace with a changing voice, the tiny microphone. For a frivolous fun.
This is Stereo Balance Indicator Circuit. You have a stereo system. But the level of both channels right and left are not the same. Yes, you can adjust with the…
In this post, I am going to show you a simple LED music light circuit. It is interesting because of similar to a VU meter circuit. Music can change the…
This is a small Stereo amplifier 3W + 3W using BA5406-IC. It use 12V power supply as source of this project. and use a few part so easy to build.
This is a bass booster circuit that use transistors as base. It is designed to increase a low frequency of audio on cheaper than ICs or normally circuit.
This 100W amplifier circuit by transistors, but very well OCL amplifier schematic.Use transistor MJ15003,MJ15004 as main. Power supply +38V 0 -38V 3A. [...]
