Cardboard

It might look like a stool, but this is actually a book. Designed by Mike Mak, Bookniture’s cardboard honeycomb structure can hold over a ton, and folds up into a book for storage when not in use. Measures 13.5″h x 14″ dia when in use, 13″h x 7″w x 1.5″d when folded.

The Q shows us how to create a battery-powered trap that can safely catch a rat or other small creature behind bars, using cardboard, wooden sticks, hot glue, and a simple electronic trigger. We’re sure a rodent could chew through it quickly, but it’s still a neat build.

The Q show off another one of their awesome low-budget builds, a robot arm that’s made primarily from cardboard and popsicle sticks, and controlled by plastic syringes filled with colored liquid. If there’s anyone we’d want to be stranded on a desert island with, it’s these guys.

The Q shows us how with just cardboard, a knife, a ruler, and some glue, you can make a simple sorter for coins of any denomination. To make one for your country’s coins, you just need to tweak the widths of the openings.

Obilab’s portable rhythm section folds down flat and fits inside a cardboard backpack, letting drummers set up impromptu jam and practice sessions pretty much anywhere – as long as it’s not raining. Listen to sample sounds at the bottom of their Kickstarter page.

Lexus UK worked with design agency NVDK, Laser Cut Works, and Scales & Models to create a full-scale, driveable replica of the Lexus IS sedan, using from 1700 laser-cut pieces of cardboard. We’re guessing it’s not as much fun to drive as the actual IS, but it’s still really cool.
