PIC Based Remote Control for Infrared or Radio Media

The project utilizes programmable PIC microcontrollers in order to create a general purpose remote control.

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.

Superhet Receiver on a 40-Meter Popcorn Version

This Superhet Receiver does not require AGC or RF control since it has satisfactory large signal handling capability as it operates with 4MHz intermediate frequency.

R/C Pulse to PWM Converter with 2 Channels

Two easily formed R/C pulse signals are converted into a PWM signal suitable for driving small motors as it uses an AVR chip and software.

RFID Tag Spoofer Based on Arduino

The purpose of the project is to spoof a simple low frequency 125kHz RFID tag with the use of an Arduino and only a few components.

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.
