Hackaday links

It was a decent weekend and it sounds like I’m going to ToorCon.  Anybody else planning on attending?

Yesterday I asked for a decent hovercraft link. [lehmon] says he followed these instructions and it worked great. Mirrored at i-hacked.

The minisub yesterday was cool, but the mini Nautilus is awesome. [anonymous]

Hackaday links

Yes, the “Best of WIN” are auto posted by someone else in the system and will probably continue to be posted long after I’m dead. If you are wondering, they turned off commenting because of us; someone seems to have deleted the comments though.

I’ll leave you with this XP alarm clock from [kth]:

It is more efficient than its friction based predecessors. The one featured here was built in 1976, but the site has a ton of other designs.
