Tokyo HackerSpace in conjunction with Safecast.org Japan have a smoking deal for you!
Buy a Chumby HackerBoard for only 5000 yen! That's about $63. Save 27 dollars!! You'll be helping our HackerSpace move into our new place.
 
A while back, Safecast picked up a case of Chumby HackerBoards, which they intended to use in crowd sourced radiation monitoring across northern Japan. Design constraints changed, and so Safecast was left holding onto the Chumbys.
