So, very simple idea, I want to have a light fade in and out when there is a new RSS feed.... I can write a program for RSS on my computer no problem (still getting a handle on embedded code) and basically, I want:

1. look at a server for any changes in my computer feeds
2. Check if the feeds have anything new
3. glow if there is anyhting new

1 and 2 wirelessly.

The only HUGE problem I see here is the wireless part -_-

ANy suggestions?

Why not use Bluetooth since lots of computers have BT now? One BT module and a boat load of program writing on both ends and you should be in.

Or you could use 2 AVRs (one at each end)
and a wireless link between them.
These look interesting to me. Low cost too...
It basically creates a one way wireless serial connection.
I'm about ready to order a few for some projects.
Spark fun has several of them and even how to hook them up to AVRs. (search for "RF link" on their site)

Here are a few from Robot shop too.

Once you have the wireless link, you
can do much more than just blink a light
if you want/need to later.

Actually, if you want to do something really
simple, go look at some of the X10 stuff.
There are tiny dongles that hook up to
a serial port that are self powered and transmit a wireless signal to an X10 receiver
that can inject the signal into your home AC wiring and could blink a light nearly anywhere in your house/building. Even supports dimming.

(But there is no AVR or embedded work involved with that type of approach).
