This is the coolest DIY electronic contest I have seen yet. I am sure it will get a ton of entries because of the grand prize, a trip to space! If you happen to win the grand prize but think that space is a bit over the top for your nerves you can always just take the cash equivalent which is close to $200K!!!! Of course there are still a ton of other great prizes to be won.
