Microcontroller based College Automation System
This project is a microcontroller-based college automation system aimed at addressing the challenges faced in educational institutions. It replaces the conventional notice board with an automated device that allows users to both hear and read the information being announced through...
H-bridge driving problemMOSFET frequently damage
An H-bridge is being utilized with IRF740 MOSFETs to convert 315V DC to 230V AC. However, the upper MOSFETs are frequently damaged within a few seconds, and the cause of this issue has not been identified.
The described circuit employs an...
Stepper Motor Driver Circuit
The following diagram is for the main circuit of the motor driver. A testing version is shown near the end of this page. It is laid out differently and shows the SN7474 in logic block form and LEDs are used...

PWM Lamp or Motor Controller
This design is intended as a dimmer for a 12V reading lamp, but it can also function as a motor speed controller for devices like drills. The circuit modulates the voltage supplied to the load, allowing for variable pulse width...
DIY Stepper Controller Circuit
The schematic for the board is illustrated below. The three primary components of the board include (1) the power input and voltage regulation, (2) the L297 input and outputs, and (3) the L298 stepper motor control circuit. The motor is...
A BIPOLAR REGENERATIVE RECEIVER
Contrary to the beliefs of some radio experimenters, an efficient bipolar regenerative design is achievable. The primary concern lies in the low input impedance of the detector-amplifier bipolar stage. However, this can be effectively compensated for with positive feedback or...
