PWM Controller Based on 555 Timer

The project aims to create a PWM controller that contains a frequency range from about 170 to 200Hz to achieve a pulse width regulation featuring almost 0-100% with a relatively stable oscillator frequency.

Google Calendar in Self-Setting Alarm Clock

The project has been renamed to Dynamically Programmable Alarm Clock (DPAC) which connects to Google Calendar through Wi-Fi and collects events for next day to calculate the best time of alarm.

2-Meter HT Radios for BASIC Stamps RF Communication

A set of 2-mter handheld radio transceivers along with Tigertronics RTX-12 Radio Modem were used in this project to provide a simple and functional result between microcontrollers long range data transmission.

Camera Switch with Servo Activated Shutter

The design of this project includes a servo being used for activating the shutter of this camera switch.

Creating the Mini Sumo Known as Seeker

A PIC16F877 microcontroller is used to control this stealthy and autonomous mini sumo called as Seeker which is packed with lots of power into a small size of under 3” high.

RC Pulse Generator

The purpose of the project is to measure resistance values and generate R/C style pulses suitable for driving servos or testing R/C controlled robots without the transmitter as it uses an Atmel AT90S2313 AVR processor.
