This is a Crystal controlled 147.460 MHz FM transmitter called XFM1.The XFM1 designed for model rockets but suitable for wildlife, balloons and many other applications requiring a small, frequency stable FM transmitter. Use this transmitter with a scanner or 2 meter amateur radio receiver. Transmitter ground range is approximately 400 yards (5 feet above ground) . Field tests were done with a ICOM IC-W32A transceiver with 0.16 micro volts of receiver sensitivity through the standard 8 inch antenna. [more]

This is a car alarm system based on PIC 12C508.This system is a perfect solution for unidirectional remote keyless entry systems and access control systems. This Alarm Sytem is based on two PIC12C508 (one is used in transmitter and the other one in the main unit). The following PICs are supported: 12c508, 12c509, 12c508a, 12c509a, 12ce518, 12ce519, 12f508, 12f509, 16f84 and 16f84a. Transmitter uses infra red beam to send code name to main unit.[more]

This is a step by step guide to building your own PCB board with lots of photos and video illustration.Printed circuit board PCB, is also known as printed wiring board PWB. The board enables the wiring to the electronic circuit to be contain on a board. This is a far more efficient method of manufacturing a larger quantity of electronics circuit.[more]

The purpose of this project is to engineer modular software and electronic components, from which it is possible to assemble an intelligent PC-based mobile robot suitable for home or office environments. This project aims to fill the gap between the powerful mobile robot platforms typically used by researchers, and the small rug-roving robots with limited processing power that are popular with hobbyists.
