would a stamp be good for this?

I have no experience in electronics but would like to make a little device that beeps when exposed to a small amount of light. I mentioned this to someone who recommended a stamp computer. other than one of the stamp kits, a light sensor and a buzzer, what else would I need and is this a good application for a stamp computer or am I better off going a different route. If I want it to be as small as possible , what would I physically build it around. Thanks in advance for helping a clueless individual out.

Can you define "a small amount of light" since that's a rather relative term, or better yet let us know what the exact application is, before we make appropriate recommendations.
No one here is about to "steal" your idea.

i am 15 so I know what i am talkin about
Step 2: Set-up the photoresistor circuit described on pg 195.
Step 3: Use the following program;
'{$STAMP BS2}
'{$PBASIC 2.5}
DO
IF (IN6 = 0) AND (IN3 = 0) THEN
FREQOUT 4, 2000, 3000
LOOP
thanks again!
Hey, that's from a Forest M. Mims (sp?) book! I bought the blue and yellow covered ones (volume I and II?) way back in the early 80's and built almost every circuit shown. Learned a lot from those books. I think mine were stolen in high school (a Catholic school, at that!) in the mid-80's.

This is the kit:

It looks like Parallax is out of stock. I bought mine at Radio Shack. Go to your local Radio Shack. If they don't have it, they'll use their computer to find one that does and ship it to your local Radio Shack at no cost....
The breadboard is only about the size of a postage stamp. The boe bot is only roughly 3 x 4 inches. It is quite small....
There's no need to buy a complete development kit or a BOEbot (unless you want to, that is
You can download a PDF of the BOE manual (www.parallax.com/dl/docs/books/edu/Roboticsv2_2.pdf) for the schematics and parts list and get the (few) parts you'd need from a local Radio Shack (assuming the ones near you still carry components).

I agree that it's a simpler solution (it's actually pretty elegant in its simplicity!) but it represents a completely different way of providing feedback to the user that the LED on the device is on or off. A method that produces a tone based on the light being on or off is potentially simpler for the user because all he has to do is listen.
With a light pipe, the user has to look at the end of the fiber to see the light. This is easily mitigated by using a clip of some kind to affix the fiber to the user's shirt so he can look down (or where ever) and see the light but that is a tiny bit more effort than just listening.
Personally, I like the idea of a little widget that generates an audible tone but that is because I am used to listening to the equipment at work (I am a manager in a Prepress department at a printing company). When there's a problem I or the machine operator usually know by the sound before we even see the alert lamps light up (sometimes even before alert tone on the equipment sounds).
