>Many people asked me, "Is it possible to control some electrical
|
|
stuff [e.g. lights, radio, tv, etc.] by using a home computer?" The answer is YES.
|
|
The process is very easy, and anyone can do it.</P

|
|
>After I read the Coffee Machine Mini-HOWTO, I got an idea of how to control
|
|
my home electrical appliances. I made some modifications on the circuit discussed in that
|
|
Coffee Machine Mini-HOWTO, and wrote a simple program. The circuit can
|
|
control many small electrical devices.^_^ You can use <B

CLASS="COMMAND"
|
|
>crontab</B
|
|
>
|
|
to set your lights to come on automatically or to turn on your airconditioner. I use it to control my VCR and VCD ( I do still need some modification on VCR/VCD).
|
|
By writing a simple program, you can control everything over the web. You can use
|
|
telnet with SSH and your telephone dial in to control all the appliances you have on the circuit.</P

|
|
>This circuit is VERY SIMPLE. Even if you don't know anything
|
|
about circuits, you can set up this circuit.</P
