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.

Basic operation of this circuit is similar DC to DC converter. With input from 18VAC at 800mA then converted to DC by B1 bridge rectifier. R11 work as adjuster, a twin of IRF510 as final amplifier, and a CT transformer is the last converter to provide the high voltage output.

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.

A simple step up DC to DC converter with a maximum draw of about 800mA. Applying a op-amp as a square wave oscillator to trig an inductor and another op-amp in a feedback loop, provides a 24V power source for many uses.

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.

This circuit is for a solar powered white LED which automatically turn on in the dark. Can be applied for outdoor or indoor night light uses. For indoor applications, when the circuit is operated near another lamp, it can be set to automatically active if the other lamp is turned off. Circuit features include selectable [...]

Based on four chips, TL072, TL074, MN3101, and MN3004 which produce four channels of output, the center, rear, front right, and front left surround audio accommodated in a signal of left and right channels. The circuit however can be applied with other basic functions as a standard decoder.

This is a small and simple audio amplifier with TDA7294. Using 2 TDA7294 for stereo (2×80 watt) mode and bridge mode (180 watt). The TDA7294 for use as class AB audio amplifier.

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.

The circuit below is an automatic switch-on emergency light. With IC as automatic controller, and and over charger protector. This circuit will drive the light on when the main power from AC source dismissed.

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 [...]
