Turning fans and uv light off electronically??

Hi every one,

At the moment when I want my case fan and UV cathode light off I have to
reach down to my case and flick a manual switch.

Is there some product or way to be able to turn these off and on
electronically through software on my computer that talks to some PCI card
or card with a serial interface that has the fan and light hooked up to it?

I assume I would need some form of relay switch board that has a serial
interface that you can send instructions to it to turn switch A or B off
independently.

Does any one know of a solution like this?

Any help greatly appreciated.

Thanks,
Adrian

I don't know directly, but you could get a microcontroller with a
serial in (maybe even a Basic Stamp), to control pins from serial
commands, which would drive relays or transistors. You'd have to write
your own software for the micro and the PC to run it.

If one is going to do programming to do the job then simply controlling an
unused serial or parallel port will do. Still need an interface with a power
transistor or relay to do the actual power switching since neither sort of
port has any serious current capacity. A parallel port can control eight
external devices (a couple more actually if you diddle the handshake lines).
