Redefined Features of Smart TV Remote

An ultrasonic sensor is used instead of push buttons in this project where it measures distance from TV as it sends different signals.

R/C Controlled Shutter Switch for Aiptek Digital Camera

The device was built around a PIC microcontroller was termed as Aip-Axe that allows programming switch-on points and switch/stick direction.

Soft Touch Designed ON/OFF Toggle Switch

A soft touch switch is illustrated in this project which can set the device ON by pushing once and set the device OFF by pushing again.

RS232 Driver for 3X Stepper Motor Using Stamp II

Simple hardware and software techniques are illustrated in this project wherein 3 common 4-coil stepper motors are driven and controlled using a single Stamp II board.

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.

Camera Switch with Servo Activated Shutter

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