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. more

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. more

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 ... more

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. more

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. more

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. more

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. more

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. more

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. more
