portable mic pre amp 2 transistor
Portable microphone preamplifier using two transistors, BC549C and BC547B. The electret condenser microphone or microphone's dynamic range is very sensitive.
The portable microphone preamplifier circuit utilizes two transistors, BC549C and BC547B, to amplify the low-level audio signals from an electret condenser...
2 watt amplifier schematic diagram
The circuit is intentionally designed using older type transistors to achieve harmonic distortion and to mitigate the challenges of sourcing high-quality components. The amplifiers can be easily powered by a plug-in wall transformer rated at 12V. When SW1 is closed,...
Mosfet Heating Circuits
This open-source thread focuses on the development of a "MOSFET Heating Circuit," which is a modified version of an existing design.
The MOSFET Heating Circuit is designed to efficiently manage and control heating elements using MOSFET technology. MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors)...
Transistor DC Transformer
A battery is a low-impedance power source. It operates most efficiently and economically when providing low voltage at high current.
Batteries serve as essential components in various electronic circuits, functioning as a reliable source of energy. Their low-impedance characteristic allows for...
Power MOSFET Bridge Rectifier
The losses in a bridge rectifier can easily become significant when low voltages are being rectified. The voltage drop across the bridge is approximately 1.5 V.
In a bridge rectifier circuit, the configuration consists of four diodes arranged in a bridge...
Easy Build Motorcycle Alarm
The following circuit is a simple, inexpensive, and easy-to-build motorcycle alarm. The circuit requires only two transistors to drive a relay, which acts as a switch to activate a buzzer. Any number of normally-open switches can be used. Mercury switches...
Power MOSFET Bridge Rectifier
The losses in a bridge rectifier can become significant when rectifying low voltages. The voltage drop across the bridge is approximately 1.5 V, which constitutes about 25% loss with an input voltage of 6V. This loss can be reduced by...
Line-activated-solid-state-switch
Each time a phone on the same line or calling number is taken off-hook, the circuit activates to control an external electronic circuit. If multiple extension telephones are connected to one phone line, the circuit serves as a busy indicator....
mosfet How to switch between a solar panel and battery
A 12V battery is charged using a solar panel. When the battery reaches 12V, the solar panel is disconnected from the battery, and the load is connected to the battery. The solar panel is reconnected to the battery when the...
