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

An Unconference Badge That’s Never Gonna Give You Uprick-badge-featuredjennylistThe badge internals.

Thu, 21 Sep 2017 05:00:00 +0000

When your publication is about to hold a major event on your side of the world, and there will be a bring-a-hack, you abruptly realise that you have to do just that. Bring a hack. With the Hackaday London Unconference in the works this was the problem I faced, and I’d run out of time to put together an amazing PCB with beautiful artwork and software-driven functionality to amuse and delight other attendees. It was time to come up with something that would gain me a few Brownie points while remaining within the time I had at my disposal alongside …read more

Fun-Size Geiger Counter Sits atop a 9-Volt BatteryIMG_5955dpsm64MVI_5957

Thu, 21 Sep 2017 02:00:00 +0000

Want a little heads-up before walking into a potentially dangerous radioactive area? Sure, we all do. But the typical surplus Civil Defense Geiger counter is just too bulky to fit into the sleek, modern every-day carry of the smartphone age. So why not slim down your first line of defense against achieving mutant status with this tiny Geiger counter (Facebook)?

We jest about the use cases for a personal-sized Geiger counter, as [Ian King]’s inspiration for this miniaturized build was based more on a fascination with quantifying the unseen world around us. Details are thin in his post, but [Ian] …read more

The Illuminated Waterways of the United StatesUS Waterway Map In Resinthehacksmith

Wed, 20 Sep 2017 23:00:00 +0000

A recent convert to the ways of the laser cutter, redditor [i-made-a-thing] was in want of a project and — stumbling on some waterways maps on Etsy — launched into fabricating an illuminated map of all the waterways in the United States.

The map itself was laser-cut out of 1/4 inch plywood at his local makerspace. Thing is, smaller rivers and tributaries were too narrow at the scale [i-made-a-thing] wanted, so he ended up spending several hours in Photoshop preparing the image so larger rivers would be laser-cut — and not break off– while the rest would be etched onto …read more

Salvaging Your Way to a Working Tesla Model S for $6500salvaged-tesla-insidesadilmalikhad

Wed, 20 Sep 2017 20:00:00 +0000

If you possess modest technical abilities and the patience of a few dozen monks, with some skillful haggling you can land yourself some terrific bargains by salvaging and repairing. This is already a well-known ideology when it comes to sourcing things like electronic test gear, where for example a non working unit might be purchased from eBay and fixed for the price of a few passive components.

[Rich] from Car Guru has taken this to a whole new level by successfully salvaging a roadworthy Tesla Model S for $6500!

Sourcing and rebuilding a car is always a daunting project, in …read more

Friday Hack Chat: All About Drones5957851505848856215brianbenchoffjoin-hack-chat

Wed, 20 Sep 2017 19:00:00 +0000

In the future, drones will fill the skies. The world is abuzz (ha!) with news of innovative uses of unmanned aerial vehicles. Soon, our flying robotic overlords will be used for rescue operations, surveillance, counter-insurgency missions, terrorism, agriculture, and delivering frozen dog treats directly from the local Amazon aerodrome to your backyard. The future is nuts.

For this week’s Hack Chat, we’re going to be talking all about unmanned aerial vehicles. This is a huge subject, ranging from aeronautical design, the legal implications of autonomous flying machines, the true efficiency of delivering packages via drones, and the moral ambiguity of …read more

Hackaday Prize Entry: MOLBED Braille Displaybraillenerdyjb

Wed, 20 Sep 2017 18:00:00 +0000

Electromechanical braille displays, where little pins pop up or drop down to represent various characters, can cost upwards of a thousand dollars. That’s where the Modular Low-cost Braille Electro Display, aka MOLBED, steps up. The project’s creator, [Madaeon] aims to create a DIY-friendly, 3D-printable,  and simple braille system. He’s working on a single character’s display, with the idea it could be expanded to cover a whole row or even offer multiple rows.

[Madeon]’s design involves using Flexinol actuator wire to control whether a pin sticks or not. He designed a “rocker” system consisting of a series of 6 pins that …read more
