I like to learn circuits about detecting temperature and light. To control various loads. Are you the same as me? Here is learning ON-OFF Light and Temperature Controller using 741…
This is 12V 10A power supply circuit can use it instead of normal 12V car battery. But save and easy to use when you are in your house.
Simple MOSFET Amplifier Circuit easy make!
This is a TDA2030 Bridge amplifier circuit diagram with PCB. It gives an output power of 35 watts to 40 watts at 8 ohms speaker. With using a +/- 15V…
This is Bass treble tone control circuit diagram as ideas, we have two circuits both transistors ,ICs-op amp as main, so smaller, but high gain signal.
The XR2206 Function Generator circuit (Sine-Triangle-Square Waveform). Frequency range : 1HZ - 1MHz, can adjusted OUTPUT Voltage. Easy to builds with PCB. [...]
This is TBA820m Amplifier circuit stereo 2W+2W, supply voltage 12V, Easy to build and cheap. on DIP-8pins same LM386. but TBA820M use easy better. [...]
