Via Universe Today comes a pointer to the Kickstarter for ISS-Above by Liam Kennedy. The ISS-Above is a

device that lights up whenever the International Space Station is nearby (that happens more often than you might expect)

[…]

The International Space Station passes overhead most of the populated areas of the world more frequently than you would imagine. If only you knew it was there.

That’s what the ISS-Above does.

It lights up when the ISS is nearby, but that’s not all. It can also TWEET a message to the Space Station and it has its own built-in web server to give you a ton of information about current and future passes.

It’s both an awareness thing, so more people get to know the Space Station is in their sky, and it’s also to let those who are “up there” know that we know and appreciate what they are doing!  

Update: A reader points to a Kickstarter project  in 2011 for a similar ISS flyover device : ISS-Notify by Nathan Bergey — Kickstarter.]

The goal of the Kickstarter is to make the device available to more people. The campaign has already exceeded its goal with over 24 days left.

From Universe Today :

A complete ISS-Above device preloaded with your location is available for kicking in to the Kickstarter for $115. If you just want the memory card with your location and custom Twitter login for sending a Tweet to the ISS, then the price is just $42. There are several other options as well.
