Not only that, but he claims that the thing could be built and launched into orbit for just a few hundred dollars. For that price, however, you're not going to be getting a big satellite. Manchester's Sprite spacecraft are actually about the size of a couple of postage stamps, but they have tiny versions of all the basic equipment that the big ones have, and yours could end up transmitting your initials from outer space.
