This is daylight sensor switch circuit, for control load turn on when have sunlight. use simple circuit LDR,transistor,relay and can use with 12V supply
Here is ic 555 inverter circuit. is easy and small size. Because use NE555 and MOSFET as main. When use source is 12V battery will have output of 100 watts.
The digital clock circuit that electronic amateurs are most interested. And The clock ICs that most popular are LM8361, MM5387,
This is DC switching power supply circuit with PCB, adjustable voltage 0-45V at 8A current max. low ripple and noise. full protection as most good supply
The Hi Fi preamplifier circuit project to tune smooth bass-treble, with a very low distortion. Use low noise transistors Frequency response range 20Hz-20KHz
This is gainclone amplifier circuit, project as stereo 40W-56 watt main amplifer use LM3875. It easy to build by 2 ICs ,more a few parts ,without any set...
This is Hybrid power amplifier circuit with PCB layout,100W-150W using STK4044XI,STK4046XI,STK4048XI so low THD and low and full protection system
