Two-phase squarewave oscillator
This circuit is one of the simplest to implement but can be challenging to comprehend. It consists of a two-transistor oscillator known as an astable multivibrator, which generates a square wave output that is out of phase. Initially, it is...
Noise making circuits
The core of the circuit is a two-transistor flasher with frequency modulation applied to the base of the first transistor. When the pushbutton is pressed, the oscillation frequency increases to a peak, and upon release, the frequency decreases due to...
expandable transistor based burglar alarm
This transistor-based alarm system incorporates automatic exit and entry delays, along with a timed bell cut-off and system reset functionality. In addition to the exit/entry zone, the fundamental alarm board includes one instant zone, which is sufficient for many applications....
100w basic mosfet amplifier
This basic MOSFET amplifier is simple to construct and low-cost, making it ideal for Hi-Fi amplifiers and instrument amplifiers such as guitars and keyboards. It delivers an output power of ±100 W RMS at an 8-ohm load or ±160 W...
mini inverter 10w 30w by transistor d313
This is a small inverter rated at 30 watts. It converts DC voltage from a 12V battery to AC voltage of 220V-230V at a frequency of 50Hz, which is the same electricity used in households. It can power 2-3 air...
Short Circuit Protection With A MOSFET
In applications where a MOSFET is employed to switch a load, incorporating short-circuit or overload protection is straightforward. This can be achieved by utilizing the internal resistance RDS(ON) of the MOSFET, which generates a voltage drop proportional to the current...
Tickler oscillator circuit
When the circuit is initially powered, neither transistor is activated, resulting in high base voltages for both and a tendency to turn on. Due to slight asymmetries, one transistor will activate first, leading the circuit into one of its states...
temperature alarm circuit
Transistors are configured as a Darlington pair in this circuit. A thermistor is utilized to detect or sense heat. A 12K variable resistor is employed to adjust the activation of the buzzer at the desired temperature. The operation of the...
Mosfet TESTER
The circuit does not guarantee the testing of all defective MOSFETs or all fault conditions in MOSFETs. If the MOSFET is functional, it will operate within the astable multivibrator circuit, resulting in the LED flashing.
The described circuit employs an astable...
