electronic cricket and blink reader?

sculpturekid

hello everyone, i am looking to use the basic stamp or other electronic or combination of devices to build two different projects. One invloves an electronic cricket. Basically i want to build a very small circuit, that will charge itself in the daytime, and at night emit a chirp. when someone approaches the chirp, it becomes quiet and an led turns on. Just like when you approach a cricket and it then becomes silent. i would like to build 5 to 10 of these so price is a concern. I am willing to pay someone to build them if the price is right but of course I also want to learn how to build these.
My second project involves a person coming up to look at the work and the work responds to the persons blinking. I have seen something similiar the measures vertical movement...I am stumped on this. Whenever the person blinks, the sculpture senses it, and it turn responds with a blink of its own. The blinking part i can handle, its the sensing part that is out of my league. Any help? Thanks, Mark

The electronic cricket is very ease to be build with the basic stamp, but when it comes to 10 pcs, price is a problem, these could be done without it, of course, but is very ease to do and test it with the BS, I use BS a lot to test some circuits and then try to reproduce then without it. ( since I don’t have many BS over here )
You said that you want the cricket to stop when someone approaches, how close?

About the work, I really did not understood what it should do! ??? ?? ?? can you explain a little better, I’m not native English so that’s might be the problem;

Here is a post for a cricket which starts when it's dark. The solar charger is a seperable circuit (unless you use the solar panel output as your darkness sensor). A robust person detector is a bit more complex, I'll leave others to discuss the pros and cons of various strategies.

I too cannot think of a robust blink detector which wouldn't require the user to wear a headset.

I looked up the "blink" sensors and the only ones I could find were those made for people with disabilities which run $500 to $600...way too much for me. I was also thinking of a whiteness detector? any ideas? I did find a cricket sound board for $10, now just trying to figure out how to do the solar cell. The board turns on at night time, so the other sensor I want to add is when someone gets close, like 2 or 3 feet. Could this be done with hear...or motion maybe?
