This is a tutorial shows you how to build your own Arduino, I name it as SalMonDuino which is derive from my name (SM Ching). SalMonDuino is an modified version of original post written by Serisman, features include:
- Using stripboard eliminate the trouble of drilling PCB holes
- Simple circuit design uses minimum of components
- Using 16MHz resonator as clock source
- Prototype area

This is a 8 channel relay box that the input connect to a controller allow it to control large loads like home appliances.
I'm using this relay box for a snooker centre to control snooker table lamps. The lamps consists of 6 pieces 20W and 3 pieces 10W fluorescent lamps, total of power consumption is 150W per table. Picture below shows the snooker table lights for the snooker centre.

This project eliminate the use of an expensive Wifi/Network Shield but still able to control home appliances from any where. You may already own a wireless router which support OpenWRT or else you can get a very cheap wireless router such as WR703N for this project.

The is a sketch for Arduino to communicate with computer or embedded device (eg. wireless router) using serial communication.
Arduino Duemilanove have 14 digital IO pins (2 digital IO used by serial) and 6 analog IO pins. Here I coded the analog IO as digital IO, so we can easily get 16 digital IO.
