tronixstuff are running an exciting competition with two prizes: an EtherMega board and a mystery prize.
From the tantalising description this sounds as if it could be your chance to win the new ARM-based Arduino due which will give you Arduino libraries running on a 32-bit CPU.
John Boxall's tronixstuff blog is a great resource if you're into Arduino. The only thing to note about the competition is that tronixstuff is based in Oz, so you may have to pay import duty, VAT and other annoyances. It still has to be well worth a go.
