Zero gravity (sort of) on a budget

zeroGravRoom

At $250,000, Virgin Galactic is probably out of most people’s price range; even reduced gravity flights run $5k. You may be in luck, though, as [Justin] and his friends have built a spinning room for $350 (Warning: loud noise @ beginning) that can turn your world upside down. The video provides a time-lapse of the build, but you’ll probably want to skip ahead 5 minutes in for the real fun.

It may not be anti-gravity, but holding onto furniture to keep from flying into the ceiling looks pretty entertaining. The room works like the fairground favorite “Gravitron” ride turned sideways. 2 forklifts support a massive wooden cube, which includes familiar features from home: drywall, flooring, and some furniture. [Justin] managed to borrow two car wheels, which he mounted in the middle of the walls on opposing sides of the cube. Two casters support each rim, and the forklifts hold the casters just high enough to allow a few friends to manually sling everything around.

DIY forklift for the home shop

lift

[Robert] does a fair bit of metal casting, and of course that means carrying around hundreds of pounds of sand, scrap, and other materials. He came up with a great solution to the inevitable back pain: a small, workshop-sized forklift able to carry around a half ton pallet.

In the actual build thread for this forklift, [Robert] goes over the design. The lift is designed to fit inside a 30″ x 7′ door frame, but is more than capable of hoisting hundreds of pounds over the operator’s head. It’s driven by two electric wheelchair motors with power provided by two car batteries. There’s also a clever bit of engineering that went into tipping the forks: instead of a hinge on the mast, [Robert] used a linear actuator on the rear wheels to put the forks at an angle.

It’s a great build, and since [Robert] does metal casting, there’s a whole bunch of custom metalwork that really adds to the build. After the break you can see a video of [Robert]‘s forklift transferring a pallet weighed down with 5 gallon buckets from one really high shelf to another. The job doesn’t take long and doesn’t require any lifting, so we’ve got to hand it to [Robert] for this build.
