You normally think of smart glasses as something you wear as either an accessory or, if you need a little assistance, with corrective lenses. But [akhilnagori] has a different kind …read more Continue reading Smart Glasses Read Text
While out swimming in the ocean on vacation, a big wave caught [QuadWorker], pushed him head first into the sand, and left him paralyzed from the neck down. This talk …read more Continue reading 37C3: The Tech Behind Life as a Quadraplegic
Video games are a great way to relax, and sometimes get your heart rate up at the same time. But unless you’re playing something like Dance Dance Revolution, the controls …read more Continue reading The Coolest Controller Mod, Hands Down
If we count all the screens in our lives, it takes a hot minute. Some of them are touchscreens, some need a mouse or keyboard, but we are accustomed to all the input devices. Not everyone can use the various methods, like cerebral palsy patients who rely on eye-tracking hardware. …read more
Some of us have computer mice with more buttons than we have fingers, resolution tracking finer than a naked eye can discern, and forced-air vents. All these features presuppose one thing; the user has a functioning hand. [Federico Runco] knows that amyotrophic lateral sclerosis, ALS, or Lou Gehrig’s disease, will …read more
Assistive devices for people with disabilities can make an inestimable difference to their lives, but with a combination of technology, complexity, and often one-off builds for individual needs, they can be eye-wateringly expensive. When the recipient is a young person who may grow out of more than one device as …read more
It’s something that can happen to all of us, that we forget things. Young and old, we know things are on our to-do list but in the heat of the moment they disappear from our minds and we miss them. There are a myriad of technological answers to this in …read more
This tip comes our way courtesy of [Elad Orbach], who’s been experimenting with a device that uses a servo to turn the function dial on a multimeter. It’s something you can put together in a few minutes with leftovers from the parts bin, and as you can see in the …read more

For their final project in embedded microcontroller class, [Aaheli, Jun, and Naomi] turned their focus toward assistive technology and created an Electronic Travel Aid (ETA) for the visually impaired that uses haptic feedback to report the presence of obstacles.
We have seen a few of these types of devices in the past, and they almost always use ultrasonic sensors to gauge distance. Not so with this ETA; it uses six VL53L0X time-of-flight (ToF) sensors mounted at slightly different angles from each other, which provides a wide sensing map. It is capable of detecting objects in a one-meter-wide swath at a …read more
One of the great successes of desktop 3D printers is custom prosthetics and orthotics. For a fraction of the price of a prosthetic arm, you can buy a machine capable of producing hundreds of completely customizable prosthetics. [Taran Ravindran]’s project in the running for the 2017 Hackaday Prize follows the long tradition of building customized prosthetics. His prosthetic hand designed to be simpler and cheaper than conventional artificial limbs while still giving us some innovation in how this hand will move.
The digits on [Taran]’s hand are controlled by linear servos pulling on a series of Bowden cables. One servo …read more
