In this project we design low cost high performance
programmable home security system using few LDR's as an
input sensors. When above sensor(s) get triggered system
may dial the user specified phone number (using build-in
DTMF generator) and activate the high power audio alarm
and lights.

XBMC is a cross
platform Media Center Application with 10-foot UI. In
this project we develop USB port base controller for
XBMC application. Main functionality of this controller
unit is to provide remote control interface, LCD base
player information panel and rotary encoder base
controller for XBMC.

This is a new design for a universal gear indicator that
can be fitted to any motorcycle as an aftermarket
accessory. Its main advantage is that its operation
depends entirely on the gear shift lever movement,
instead of connecting to speedometer ...

The present document shows step by step how to easily
build an interesting pointing device: the wireless tilt
mouse, that allows to control the mouse's cursor on the
PC screen through the tilt of the board itself. The
analog data from a 3-D accelerometer and from two
push-buttons are acquired, converted and radio
transmitted by an XBee module using the standard ZigBee
protocol.

This project is a new implementation of the
AVR DDS signal generator v2.0 found on
scienceprog.com. Itis a firmware based
DDS signal generator and has two outputs - one for DDS
signal and another for high speed [1..8MHz] square
signal. Offset and amplitude can be regulated by two
potentiometers. Offset can be regulated in range
+5V..-5V while amplitude in range 0..10V.

Lithium Polymer Batteries are a very common source of
power today. Many electronics gadgets have one inside,
and they have some reasonable features. I've bought
great batteries, with different sizes and capacities for
my electronics projects. So long I'm using this
batteries, coming the problem: charge them.

In this project it was used the
"Piranha
Super-flux RGB" Led of common anode, and the
PIC18F25K20, in order to generate
combinations of colors. It has two function
modes, automatic that generate the color
sequence that is stored in the uC memory,
and the manual mode in which you can select
one of the seven possible colors.

This project
describes how to build an IR remote control extender /
repeater to control your electronic appliances from a
remote location. An IR detector module receives IR
signal from remote control and two IR leds are
re-emitting the signal to the appliance. You can place
the IR emitting leds close to the device you would like
to control using some wire and keep main unit close to
remote control location.

This is a smoke / gas detection circuit.
The sensor is the GH-312 sensor and it is used to detect
: smoke, liquefied gas, butane and propane, Methane, alcohol, hydrogen, etc. Also has a 16F84A
microcontroller and a 8X2 LCD.
