A power bank can supply 9 V or 12 V only when its output port supports that voltage and the connected device or trigger requests it using a compatible charging protocol. A USB connector alone does not tell you which voltages are available. Cover: AI-generated conceptual illustration, not a wiring diagram or evidence of a … Read more
A simple 12V inverter with 555 IC and IR2103 MOSFET driver is an electronic device that can convert DC (direct current) voltage from a battery or other DC sources to AC (alternating current) voltage suitable for powering various appliances and devices. The circuit utilizes the 555 timer IC and IR2103 MOSFET driver in combination with … Read more
CD4047 Pinout The CD4047 is a low-power CMOS multivibrator IC commonly used in inverter circuits, oscillator applications, and timing circuits. It can operate in astable mode to generate continuous square-wave signals or in monostable mode to produce a single timed pulse. In a basic push-pull inverter design, the CD4047 generates complementary output signals that can … Read more

It works off a 9V battery. MEDIUM-POWER FM TRANSMITTER The range of this FM transmitter is around 100 meters with a 9V … Read more
Battery-Low Indicator Rechargeable batteries should not be discharged below a certain voltage level. This lower voltage limit depends upon the type of the battery. This simple circuit can be used for 12V batteries to give an indication of the battery voltage falling below the preset value. The indication is in the form of a flickering … Read more
Introduction In present day virtual age, electronic gadgets have end up an essential a part of our lives, which include musical devices. One fascinating task for music fans and electronics hobbyists is building a easy electronic piano or organ the use of an astable circuit. An astable circuit is a sort of oscillator that generates … Read more
Conversion of AC to AC is quite simple as in compare to DC to DC converter because it only implies a transformer which converts AC from one voltage level to another voltage level. But conversion of DC to DC is quite tedious work without transformer and more power losses. Here is simple, low-cost, high precision … Read more
What is a Crystal AM Transmitter? A crystal AM transmitter is a radio transmitter that uses a crystal oscillator to generate the service frequency. The crystal oscillator is an exceedingly solid device that produces a very precise frequency, which is essential for AM transmitters. The audio signal is then modulated onto the carrier frequency with … Read more
A two-transistor astable multivibrator alternates between two states without a clock input. Each transistor switches one LED, while capacitors couple the two stages. It is often called an LED “flip-flop”, although an astable oscillator keeps switching rather than holding a stable logic state. The cover is an AI-generated parts illustration, not a wiring diagram. This … Read more
this project that I am sharing today is an IR2153 push-pull inverter, the circuit converts 12VDC volt from a battery to 220v AC voltage. The circuit uses IR2153 ic as the oscillator and MOSFETs to drive the transformer and it is in a push-pull configuration to get a high-efficiency voltage conversion. Here are the steps … Read more
