That reverse hammer is fascinating. I'm a little confused by the diagram, though -- I think the magnet stays on the instrument's surface for the entire motion. It never comes away from the instrument, even after the hammerhead hits the stop

It depends how you view reddit. If you want jokes, try Fark or Digg. If you want more technical news, try Slashdot, in addition to HN. If you want a ton of memes, try 4chan. But those aren't all the topics discussed on Reddit. Reddit seems

I wonder what the production cost of this is compared to a "traditional" heatsink. It looks like it would require more metal, but I'm not sure. I don't know if it would require more precision in the construction process, but this smells lik
