This inverter circuit is very useful for low load application such as emergency light, radio, or DVD player. With transistors as main active component, please take more attention when you assemble this 100 W inverter circuit. Power source of this circuit just 12V DC, but can produce about 100W at 220V AC with simple assembling [...]

Using IC 4001, 4027, NE555, and CA3130, this circuit can convert 24VDC to 220VAC 300W. A pairs of MJ15003 or 2N3773 as the last active components before drive the pulse into the transformator.

IC Op-amp 741 as main chip for Infra Red receiver and transmitter. Infra Red LED connected with SCR trigger by pulse which produced from this Op-amp 741 when the SW in close position.

The circuit using active component to operating. In this case, the active component is IC NE5532 or TL072 as a linear part. With 15 V power supply, this circuit separate the low out and high out. The low out connected to a woofer, and high out in tweeter.

Composed of two similar mono amplifier. Each channels has its own power supply. This class A audio amplifier take 50V as the fuel, and will produce very loud sound output without distortion.

For large source supply at your amplifier or another application, this DC-DC converter is recommended. This circuit already tested, and no problem when connected the load.

This circuit ease you to control any appliance with infra red remote. Can be used for electrical devices like lamp, fan, etc. With power supply from itself, the circuit make the application compact and easy to control. The circuit looks for any modulated IR source and uses it to control a TRIAC, which then switches [...]

Power amplifier settled on HEXFET IRF9540 and IRF540 which probably produce 65 W at the output. This circuit is simple and have a good audio quality. For thermal static, use heatsink on Q8, Q10, Q11, Q12, and Q13.
