Here are some circuits: http://circuitos.tripod.cl/schem/r15.gif http://ourworld.compuserve.com/homepages/Bill_Bowden/page10.htm#15flash.gif http://electronicsworld.tripod.com/lightsimages/lightsckt1.html
There are tons more. The last one uses a 555 timer chip. It looks at first glance to be the best of the three above.

I have seen these for sale for telescopes so that you know where tripod legs are and what not. If you can not find any, they should be pretty easy to build with a minimum of components.

You can buy a flashing LED which requires nothing more than just power being applied to it. Check out your local Radio Shack for one. The circuit is actually inside the LED lens itself making it the best solution.

I'm looking for a red LED that flashes about once a minute and is powered by 2 AA batteries. I got one from a display box that was used for a web camera or something. It's on a pretty small board. I'd like something just like it. Where do you find something like this? -- Cheers, joeuser (still looking for the 'any' key)
