My Device can control bedroom lights via Internet or Phone

I was really bored, so I invented a device which allows me to turn the lights in my bedroom on and off simply by connecting to a webpage. This works from any computer (assuming it knows the link), or from any phone capable of connecting to the internet.

I soldered the circuits and connectors myself, and wrote the software myself; everything was built from scratch.

It uses a relay attached to a transistor switch which is attached to the computer's parallel port. I wrote software (in C++, running on a very basic Linux setup) which, upon receiving a connection request, sends voltage back out through the parallel port, activating the transistor, allowing voltage to flow through to the relay. The power is drawn from the computer's 9v power supply (I soldered a connector to make it easy to plug in to the computer).

This is the most useless device ever created.

No, you can't explain it very well. "This thing goes into this thing, that goes into another thing." Wow, you should be writing manuals for Microsoft.

I'm currently in the process of making a website with tutorials on the work I've done for various projects. I'll reply to your comment with a link once it's done.

Thanks for the interest.

Vexal, this is great! Do you happen to have a page detailing the components and how you connecting everything? (For us noobs :D)

It would be great for people who are injured or who have limited mobility. If they forgot to turn the lights off somewhere in the house they can control everything via the computer. Even better, if someone is away from their home and just remembered they forgot to shut off the lights (or some other appliance), they can use the browser on their phone to control it.

I'm currently in the process of making a website which will have explanations on how to do things like this.
