Hackaday Prize Entry: Dynamometer for Post Stroke Rehabilitation

Posted on by

For those who have suffered a stroke, recovery is a long and slow process that requires rehabilitation to start as early as possible. Quite often, secondary stroke attacks complicate matters. Spasticity — muscle contraction and paresis — muscular weakness, are two of the many common after-effects of stroke. Recovery involves doing repeated exercises to strengthen the muscles and bring back muscle memory. Benchmarking progress becomes difficult when caregivers are only able to use qualitative means such as squeezing tennis balls to monitor improvement. To help provide quantitative measurements in such cases, [Sergei V. Bogdanov] is building a Dynamometer for Post-Stroke …read more

Hackaday Prize Entry: Hand Tremor Suppression Wearable Device

Posted on by

It is extremely distressing to watch someone succumb to an uncontrollable hand tremor. Simple tasks become frustrating and impossible, and a person previously capable becomes frail and vulnerable. Worse still are the reactions of other people, in whom the nastiest of prejudices can be unleashed. A tremor can be a debilitating physical condition, but it is not one that changes who the person afflicted with it is.

An entry from [Basian Lesi] in this year’s Hackaday Prize aims to tackle hand tremors, and it takes the form of a wearable device that tries to correct the tremors by applying small …read more

Hackaday Prize Entry: Wheelchair User Pressure Relief Indicator System

Posted on by

It is difficult to put yourself as an able-bodied person into the experiences of a person with a physical disability. Able-bodied people are quick with phrases such as “Confined to a wheelchair” with little idea of what that really means, and might be surprised to meet wheelchair users who would point out that far from being a prison their chair might, in fact, be their tool of liberation.

It is also difficult for an able-bodied person to understand some of the physical effects of using a wheelchair. In particular, some wheelchair users with paralysis can suffer from dangerous pressure sores …read more

Hackaday Prize Entry: Ebers – Diabetes Care, Step By Step

Posted on by

Diabetes is a disease that, among other things, has significant effects on the feet due to a combination of neuropathy, vascular issues, and other factors. You may have seen special diabetes socks with features like non-elasticated cuffs for better circulation and a lack of seams to prevent the formation of blisters. Taking care of  your feet is essential in diabetes to prevent injury and infection. Ebers is a project that seeks to help in just this area.

Ebers monitors plantar pressure, temperature, and humidity in the sole of the shoe. It then feeds this data back to a smartphone for …read more

Hackaday Prize Entry: Visioneer Sensor HUD

Posted on by

Only about two percent of the blind or visually impaired work with guide animals and assistive canes have their own limitations. There are wearable devices out there that take sensor data and turn the world into something a visually impaired person can understand, but these are expensive. The Visioneer is a wearable device that was intended as a sensor package for the benefit of visually impaired persons. The key feature: it’s really inexpensive.

The Visioneer consists of a pair of sunglasses, two cameras, sensors, a Pi Zero, and bone conduction transducers for audio and vibration feedback. The Pi listens to …read more

Hackaday Prize Entry: TooWheels, The Open Source Wheelchair

Posted on by

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 …read more

Hackaday Prize Entry: Adaptive Guitar

Posted on by

Due to a skiing accident, [Joe]’s new friend severed the motor nerves controlling her left arm. Sadly she was an avid musician who loved to play guitar — and of course, a guitar requires two hands. Or does it? Pressing the string to play the complex chords is more easily done using fingers, but strumming the strings could be done electromechanically under the control of a foot pedal. At least that’s the solution [Joe] implemented so beautifully when his friend’s family reached out for help.

There are just so many things to enjoy while reading through [Joe]’s project logs on …read more
