Ikea Furniture Hacks Make Accessibility More Accessible

March 31, 2019 by Roger Cheng 11 Comments

The ThisAbles project is a series of 3D-printed IKEA furniture hacks making life easier for those without full use of their bodies. Since IKEA furniture is affordable and available across most of the planet, it’s the ideal target for a project that aims to make 3D-printed improvements accessible to everyone.

These hacks fit all meanings of the word “accessible”: Available worldwide, affordable, and helping people overcome physical barriers of everyday living. ThisAbles has support of multiple organizations including IKEA Israel. In their short introductory video (embedded below the break) they explained their process to find ways to make big impacts with simple 3D-printed modifications. From bumpers protecting furniture against wheelchair damage, to handles that allow drawers to be opened without fine fingertip control. Each of these designs also fit the well-known IKEA aesthetic, including their IKEA style illustrated manuals.

The site launched with thirteen downloadable solutions, but they have ambitions for more with user feedback. There’s a form where people can submit problems they would like to see solved, or alternatively, people can submit solutions they’ve already created and wish to share with the world. Making small changes to commodity IKEA furniture, these 3D printed accessories will have far more impact on people’s lives than the average figurine trinket on Thingiverse. It’s just the latest way we can apply hacker ingenuity to help others to do everything from simple daily tasks to video gaming.

Overlooked Minimalism In Assistive Technology

November 23, 2018 by Brian McEvoy 27 Comments

If your eyes are 20/20, you probably do not spend much time thinking about prescription eyeglasses. It is easy to overlook that sort of thing, and we will not blame you. When we found this creation, it was over two years old, but we had not seen anything quite like it. The essence of the Bear Paw Assistive Eating Aid is a swiveling magnet atop a suction cup base. Simple right? You may already be thinking about how you could build or model that up in a weekend, and it would not be a big deal. The question is, could you make something like this if you had not seen it first?

Over-engineered inventions with lots of flexibility and room for expansion have their allure. When you first learn Arduino, every problem looks like a solution for that inexpensive demo board and one day you find yourself wearing an ATMEGA wristwatch. Honestly, we love those just as much but for an entirely different reason. When all the bells and whistles are gone, when there is nothing left but a robust creation that, “just works,” you have created something beautiful. Judging by the YouTube comments of the video, which can be seen below the break, those folks have no trouble overlooking the charm of this device since the word “beard” appears 95 times and one misspelling for a “bread” count of one. Hackaday readers are a higher caliber and should be able to appreciate its elegance.

The current high-tech solution for self-feeding is a robot arm, not unlike this one which is where our minds went when we heard about an invention about eating without using hands, and we will always be happy to talk about robot arms.

Open Gaming To Everyone With A Controller Meant To Be Hacked

May 17, 2018 by Roger Cheng 35 Comments

Gaming controllers have come a long way from an Atari 2600’s single button and digital joystick. As games grew more sophisticated, so did the controllers. This development had a dark side – controllers’ growing complexity have made it increasingly difficult for different-abled bodies to join in the fun. Microsoft has extended an invitation to this audience with their upcoming Xbox Adaptive Controller.

Creative minds have been working on this problem for a while, building an ecosystem of controller hacks to get more people into gaming. These projects require solving problems in two broad categories: the first is to interface with input devices that match a specific user’s needs, the second is then integration into target game device’s control infrastructure.

The value of XAC is eliminating the second category of work and making it reliable: it takes care of all the housekeeping overhead of creating a custom Xbox controller, from power management to wireless communication. As for input device interface, every control needed to play on a Xbox is individually mapped to a standard 3.5 mm jack. Some are pure digital ports, others can transfer an analog value. A 3.5mm plug is a proven consumer-friendly interface that’s easy to work on by anyone who wants to pick up a soldering iron, making this array of jacks a wide-open gateway to limitless possibilities. The 3.5 mm jacks make it easy to build specific configurations, and make it easy for less-technical people to reconfigure for a different player or different game.

We love to see our hacker creativeness applied to help people live normal lives. Making it easy to hack up a custom gaming controller may not be earth shattering, but don’t underestimate the importance of letting people feel included. It does transform lives, one at a time. Plus, it looks like fun to play with.

Rapidly Prototyping Prosthetics, Braille, And Wheelchairs

February 23, 2018 by Anool Mahidharia 4 Comments

We live in an amazing time where the availability of rapid prototyping tools and expertise to use them has expanded faster than at any other time in human history. We now have an amazing ability to quickly bring together creative solutions — perfect examples of this are the designs for specialized arm prosthetics, Braille printing, and custom wheelchair builds that came together last week.

Earlier this month we published details about the S.T.E.A.M. Fabrikarium program taking place at Maker’s Asylum in Mumbai. The five-day event was designed to match up groups of makers with mentors to build assistive devices which help improve the condition of differently-abled people.

The participants were split into eight teams and they came up with some amazing results at the end of the five-day program.

Hands-On: Prosthetic Designs That Go Beyond

Three teams worked on projects based on Bionico – a myoelectric prosthesis

DIY Prosthetic Socket – a Human Machine Interface : [Mahendra Pitav aka Mahen] lost his left arm during the series of train bomb blasts in Mumbai in 2006, which killed 200 and injured over 700 commuters. He uses a prosthetic arm which is essentially a three-pronged claw that is cable activated using his other good arm. While it is useful, the limited functionality restricted him from doing many simple things. The DIY Prosthetic socket team worked with [Mahen] and [Nico Huchet] from MyHumanKit (who lost his right arm in an accident 16 years back), and fabricated a prosthetic forearm for [Mahen] with a modular, 3D printed accessory socket. Embedded within the arm is a rechargeable power source that provides 5V USB output at the socket end to power the devices that are plugged in. It also provides a second port to help recharge mobile phones. Also embedded in the arm was an IR reflective sensor that can be used to sense muscle movements and help trigger specific functions of add-on circuits, for example servos.

S.T.E.A.M. Fabrikarium Builds Assistive Tech In Mumbai

February 7, 2018 by Anool Mahidharia 3 Comments

Starting this weekend, a group of 65 invited Maker’s from various disciplines, along with 20 awesome Mentors, will gather at the Maker’s Asylum in Mumbai for the five day S.T.E.A.M. Fabrikarium program. The aim is to improve the capabilities of the differently-abled by building and expanding upon existing open source projects. At the same time, the teams will learn more about rapid prototyping techniques.

Among the participants will be at least 15 differently-abled people who will be a part of the whole process of learning as well as providing their inputs on the problems being tackled. Participants have an opportunity to understand how design thinking works and work on improving the existing designs.

Participants will team up and choose from five existing open source projects:

Bionico – a myoelectric prosthesis
Braille rap – using a 3D printer as a braille embosser.
e-Trotti – a low-cost, removable electrical assistance for wheelchair use, made from electric scooter parts.
Project Shiva – customized and beautiful upper limb prosthetics.
Flying Wheelchair – a wheelchair specially adapted for use while paragliding.

The Asylum’s fully-fledged workshop facilities offer a wood shop, a laser cutter, a CNC, several 3D printers, electronics tools and instruments and an infectious environment that will allow the participants to learn a lot during the five short days. While working on prototyping their projects, all teams will have constant access to a team of mentors and industry experts who will help solve their problems and give guidance when necessary.

The Maker’s Asylum includes fully-fledged workshop facilities for the build process, and the team succeeded in bringing onboard a slew of industrial partners and supporters to ensure that the program can be offered to the participants for free. That is a great way to bring makerspaces, makers, and the industry together in a symbiotic program that benefits society. The program was developed in collaboration with My Human Kit, a company from France who selected the five open-source projects mentioned above. The Fabrikarium is made possible via Bonjour-India, which fosters Indo-French partnerships and exchanges.

Hackaday is proud to be a part of this program and will be present to help document all of the awesome projects. Participants will share their progress on Hackaday.io, so watch for updates over the coming week. To get an idea of what to expect at the S.T.E.A.M. Fabrikarium 2018, check out the video from an earlier version embedded below.

Hackaday Prize Entry: TooWheels, The Open Source Wheelchair

September 27, 2017 by Anool Mahidharia 17 Comments

The Assistive Technology challenge of the Hackaday Prize received a large number of projects addressing many socially relevant problems. Mobility and transportation needs are a big challenge for those with limb disabilities. Not every country has proper, state-subsidised health care systems, and for many people in third world countries, devices such as wheel chairs are just not affordable. [Alessio Fabrizio] and his team developed TooWheels — an Open Source DIY wheelchair which can be customized and built using low-cost, local materials around the world and is one of the winners of the Assistive Technologies challenge round.

Originally conceived as a sport wheelchair, it has now evolved to answer different needs, due to feedback from the users and the community involved in the project. [Alessio] designed the project to be built from materials and resources easily available to any DIY maker at today’s Fab Labs and Makerspaces. The team have provided a detailed BOM to help procure all the required materials, instruction manual and drawings for assembly, and all the CAD files with customization instructions. Already, teams in Ecuador, India and Italy have replicated and built their own version of the TooWheel wheelchair. This confirms that the project is well documented and allows anyone around the world to download the plans and follow instructions to build their own wheelchair.

The wheelchair is built from CNC cut plywood sheets, aluminum pipes and bicycle parts and wheels. This makes it substantially cheaper compared to commercial wheelchairs, making it especially relevant for people in third world areas or where health care is not subsidised. The ease of customization allows fabrication of different wheelchair designs for sports, off-road or city use. The team is looking to bring this low-cost design to people around the world and are keen to collaborate with teams around the world to make it happen.

Building Custom Game Controllers For People With Physical Disabilities

June 20, 2013 by Caleb Kraft 81 Comments

Hold on tight. This is going to be a long post. I kept my temper in the video, but here I can just come out and let you know that I’m livid. Every time I start thinking about this, I feel so angry and helpless that my face gets hot and my hands get shaky. I’m getting ahead of myself though, so lets just back up a little bit and talk about a pretty cool kid named [Thomas].

[Thomas] has muscular dystrophy. This means he’s going to gradually lose strength and control in his muscles over time. He has already lost his ability to stand, and even holding buttons on a game-pad for extended times can be difficult. Gaming, as you can imagine, is very important to [Thomas] and people like him. It offers a release of frustration, like it does for all of us, but also a level playing ground. When he’s in the game, he’s like everyone else.
