Hackaday Prize Entry: A 3D Printed Prosthetic Foot

Posted on by

For the last few years of the Hackaday Prize, there have been more than a few prosthetic devices presented. Almost without exception, the target for these projects are prosthetic hands. That’s a laudable goal, but mechanically, at least, feet are much more interesting. A human foot must sustain more than the weight of the human it’s attached to, and when it comes to making this out of plastic and metal, that means some crazy mechanics.

This Hackaday Prize entry is a complete reversal of all the prosthetic limbs we’ve seen before. It’s a prosthetic foot, and in the tradition of …read more

Hackaday Prize Entry: FLipMouse

Posted on by

The theme of the last Hackaday Prize challenge was Assistive Technologies, and with this comes technical solutions for people with severe motor restriction. One of the best we’ve seen is a device designed to use a sip and puff interface and buttons to control a cursor through USB. The almost too clever name for a device meant to be used via fingers or lips is the FLipMouse, and right now it’s in the running for the finals in the Hackaday Prize.

The FLipMouse isn’t so much a mouse as it is a very long and very sensitive joystick. The main …read more

Hackaday Prize Entry: A Cheap, Portable Incubator

Posted on by

Millions of premature babies are born every year, and more than a few of these births occur hours away from any hospital with a NICU. [Manoj]’s entry for the Hackaday Prize is a simple, but very useful primitive incubator. Is it as good as the incubators you would find in a world-class hospital? No, but that’s not the point. This is an incubator for the rest of the world, where neonatal care is lacking.

You’re not going to get mechanical respiration or even oxygen into a device that is meant for the most far-flung areas on the planet, so this …read more

Hackaday Prize Entry: An Open Bluetooth Switch Interface

Posted on by

The theme of the last Hackaday Prize challenge was Assistive Technologies, and there is perhaps no assistive technology as desperately needed as a device to help people who can’t use common input devices. Using a keyboard, mouse, or touchscreen can be hard, but this Hackaday Prize project turns all these problems into a simple Bluetooth-enabled switch.

The BOSI – the Bluetooth Open Source Switch Interface – is, at its heart, just a big Bluetooth button inside a 3D-printed enclosure designed in Solidworks. These enclosures house a button connected to an Adafruit Bluefruit EZ-Key. Add a battery and a charging circuit, …read more

Hackaday Prize Entry: Hands|On Gloves Speaks Sign Language

Posted on by

The Hands|On glove looks like it’s a PowerGlove replacement, but it’s a lot more and a lot better. (Which is not to say that the Power Glove wasn’t cool. It was bad.) And it has to be — the task that it’s tackling isn’t playing stripped-down video games, but instead reading out loud the user’s sign-language gestures so that people who don’t understand sign can understand those who do.

The glove needs a lot of sensor data to accurately interpret the user’s gestures, and the Hands|On doesn’t disappoint. Multiple flex sensors are attached to each finger, so that the glove …read more

Hackaday Prize Entry: Augmented Reality Historical Reenactments

Posted on by

Go to a pier, boardwalk, the tip of Manhattan, or a battlefield, and you’ll see beautifully crafted coin operated binoculars. Drop a coin in, and you’ll see the Statue of Liberty, a container ship rolling coal, or a beautiful pasture that was once the site of terrific horrors. For just a quarter, these binoculars allow you to take in the sights, but simply by virtue of the location of where these machines are placed, you’re standing in the midsts of history. There’s so much more there. If only there was a way to experience that.

This is why [Ben …read more

These 20 Projects Won $1000 For Assistive Technologies

Posted on by

For the last seven months, Hackaday has been hosting the greatest hardware competition on Earth. The Hackaday Prize is a challenge to Build Something That Matters, asking hardware creators around the world to focus their skills to change the world.

The results have been spectacular. In five rounds of design challenges, we’ve seen more than 1000 entries and so far eighty of them have won $1000 and a chance to win the Grand Prize: $150,000 and a residency at the Supplyframe DesignLab in Pasadena.

Last week, we wrapped up the last challenge for the Hackaday Prize: Assistive Technologies. We’re …read more

Hackaday Prize Entry: Raspberry Pi Zero Smart Glass

Posted on by

Some of the more interesting consumer hardware devices of recent years have been smart glasses. Devices like Google Glass or Snapchat Spectacles, eyewear incorporating a display and computing power to deliver information or provide augmented reality on an unobtrusive wearable platform.

Raspberry Pi Zero Smart Glass aims to provide an entry into this world, with image recognition and OCR text recognition in a pair of glasses courtesy of a Raspberry Pi Zero. Unusually though it does not take the display option of other devices of having a mirror or prism in the user’s field of view, instead it replaces the …read more

Hackaday Prize Entry: Vendotron

Posted on by

A recurring idea in hackspaces worldwide seems to be that of the vending machine for parts. Need An Arduino, an ESP8266, or a motor controller? No problem, just buy one from the machine!

Most such machines are surplus from the food and drink vending industry, so it’s not unusual to be able to buy an Arduino from a machine emblazoned with the logo of a popular chocolate bar. These machines can, however, be expensive to buy second-hand, and will normally require some work to bring into operation.

A vending machine is not inherently a complex machine nor is it difficult …read more

Hackaday Prize Entry: FPGAs For The Raspberry Pi Zero

Posted on by

The Raspberry Pi is the Arduino of 2016, and that means shields, hats, add-ons, and other fun toys that can be plugged right into the GPIO pins of a Pi. For this year’s Hackaday Prize, [Valentin] is combining the Pi with the next age of homebrew computation. He’s developed the Flea Ohm, an FPGA backpack or hat for the Pi Zero.

The Flea Ohm is based on Lattice’s ECP5 FPGA featuring 24k LUTs and 112kB BRAM. That’s enough for some relatively interesting applications, but the real fun comes from the added 32MB or 128MB of SDRAM, a micro SD card …read more
