Pneumatic Origami

Odds are that if you’ve been to the beach or gone camping or somewhere in between, you are familiar with inflatable products like air mattresses. It’s nothing spectacular to see a rectangle inflate into a thicker, more comfortable rectangle, but what if your air mattress inflated into the shape of a crane?

We’ve seen similar ideas in quadcopters and robots using more mechanical means, but this is method uses air instead. To make this possible, the [Tangible Media Group] out of [MIT’s Media Lab] have developed aeroMorph — a program that allows the user to design inflatable constructs from paper, …read more

Cardboard and Paper Gun Shows Off Clever Construction

This project by [blackfish] shows off a cardboard lookalike of an MP5 that loads from a working magazine, has a functional charging handle, and flings paper projectiles with at least enough accuracy to plink some red party cups. It was made entirely from corrugated cardboard, paper, rubber bands, and toothpicks.

In the video (embedded below) you can see some clever construction techniques. For example, using a cyanoacrylate adhesive to saturate areas of wood, cardboard, or paper to give them added strength and rigidity. The video is well-edited and worth a watch to see the whole process; [blackfish] even uses a …read more

Paper Circuit Does Binary Math with Compressed Air

Most of us can do simple math in our heads, but some people just can’t seem to add two numbers between 0 and 3 without using paper, like [Aliaksei Zholner] does with his fluidic adder circuit built completely of paper.

There’s some good detail in [Aliaksei]’s translated post on the “Only Paper” forum, a Russian site devoted to incredibly detailed models created entirely from paper. [Aliaksei] starts with the basic building blocks of logic circuits, the AND and OR gates. Outputs are determined by the position of double-headed pistons in chambers, with output states indicated by pistons that raise a …read more

God of Papercraft Builds Working Organ Used for Own Adulation

There’s a wide world to explore when it comes to papercraft, but we reserve special praise for fully functional builds. [Aliaksei Zholner’s] working papercraft organ is a stunning example of what can be achieved with skill and perseverance.

The video is short but covers some finer touches – the folded concertinas of paper acting as springs to return the keys, for example. Air is supplied by a balloon, and the organ has a tone similar to other toy organs of comparable size.

The builder has declined to share templates at this stage, due to the complexity of the model and …read more
