R/C Controlled Shutter Switch for Aiptek Digital Camera

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.

Redefined Features of Smart TV Remote

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.

Flash Sync Box with Multiple Functions

The project demonstrates how an old AC wall wart was used to create a homemade USB charger for handheld electronics such as Personal Game machine, Digital Camera, or MP3 Player.

Homemade Wi-Fi Antenna with Cylindrical Parabolic Template

Homemade Wi-Fi Antenna with Cylindrical Parabolic Template

The project illustrates the creation of an antenna for an access point by designing the reflector to be fed by a dipole.

Discrete Diodes Used to Build Digital Clock

Discrete Diodes Used to Build Digital Clock

The project aims to build a digital clock by using an Arduino while lighting up a group of discrete LEDs wherein each segment is driven by transistor since they require more power.
