So I had an idea after eating a kinder-egg today. The kinder egg has a little "egg" inside that has a little toy. And I wanted to make use of the "egg". I was going to make a Wifi Locator.
Essentially it would jsut be a little led that sticks out the top of it and it would light up when there was a wifi network avaliable. Possibly even an RGB LED that would change color according to how strong it was.
Does anybody know of any compact solution for this? If not wifi than does anybody know about one for AM and FM radio waves?
Thanks in advance
