Build a levitating bed for under $1000

Many of us have had this exact thought and wondered if it was feasible. As it turns out, you can, in fact, just buy a bunch of magnets and make a levitating bed. Those magnets need to be extremely strong, so [mememetatata] used some rather large Neodymium magnets. This frame involved some careful planning since these magnets can actually be quite dangerous if not handled properly. [mememetatata] did manage to get everything spaced correctly and now has a bed that can levitate holding up to about 250 lbs. We really want to know what it feels like. That kind of thing seems as though it would be difficult to describe.

As usual, more information might be available in the reddit thread.

Engineering with magnetic spheres

We would imagine these experiments were spawned by a devastatingly boring day at the office. [Sparr] found himself the proud owner of one thousand rare-earth magnets and decided to see what geometric shapes he could build with the spheres. These are gold-plated N35 Neodymium magnets that measure just 6mm across. He discovered that every structure is built from rings of magnets with shapes dependent upon what sequence of increasing or decreasing members are used. What he’s done is visually pleasing but we’d like to try it ourselves to see how resilient each structure ends up being.

[Sparr's] post is from the Freeside Atlanta blog, a hacker space collective. [Curbob], a regular with the group, tipped us off that a few hacker conventions are coming up in their area and they’re looking for speakers for one-hour talks about projects. If you’re near Raleigh or Atlanta this is your chance to show off that ridiculously complicated project you’ve been risking your marriage to complete.
