CIPODS: Earbuds for Cochlear Implants

If you wear cochlear implants, sound doesn’t enter through your ear, but rather from microphones above your ears. That means earbuds are useless and you have to resort to large and clumsy over the ear headphones. [Mjcraig23] wanted the convenience of earbuds and set out to do what we all do: hack it.

The result is handily portable as you can see in the video, below. The trick is that he used replacement battery covers and then grafted earbud holders (called EARBUDi) to them using one of our favorite fasteners, zip ties. Apparently, you can wire a cable directly into …read more http://pje.fyi/QK5lhV

Homebrew Wrist Brace Helps Beat Injury with Style

Repetitive motion injuries are no joke, often attended by crippling pain and the possibility of expensive surgery with a lengthy recovery. Early detection and treatment is the key, and for many wrist and hand injuries such as [ktchn_creations] case of “Blackberry thumb,” that includes immobilization with a rigid brace.

Sadly, the fiberglass brace her doctor left her with was somewhat lacking in the style department, and rather than being left with something unappealing to wear for half a year, she 3D-printed a stylish and functional wrist immobilizer. Starting in Autocad, she designed the outline of the brace, essentially an unwrapped …read more http://pje.fyi/QGRGnt

MIT Makes Lego Lab For Microfluidics

As any good hacker (or scientist) knows, sometimes you find the tools you need in unexpected places. For one group of MIT scientists, that place is a box of Lego. Graduate student [Crystal Owens] was looking for new ways to make a cheap, simple microfluidics kit. This technique uses the flow of small amounts of liquid to do things like sort cells, test the purity of liquids and much more. The existing lab tools aren’t cheap, but [Crystal] realized that Lego could do the same thing. By cutting channels into the flat surface of a Lego brick with a precise …read more http://pje.fyi/QDtgLv

Lamp Analysis Tells Sad Truth Behind The Marketing Hype

Here in the northern hemisphere, winter has wrapped us in her monochromatic prison. A solid deck of gray clouds means you need a clock to tell the difference between night and day, and by about the first week of February, it gets to feeling like you’ll never see a blue sky again. It’s depressing, to be honest, and the lack of sunlight can even lead to a mood disorder known as SAD, or seasonal affective disorder.

SAD therapy is deceptively simple — bright full-spectrum light, and lots of it, to simulate the sun and stimulate the lizard brain within us. …read more http://pje.fyi/QB7PJp

[Rhonda] has multiple sclerosis (MS), a disease that limits her ability to walk and use her arms. She and the other residents of The Boston Home, an extended care facility for people with MS and other neuromuscular diseases, rely on their wheelchairs for mobility. [Rhonda]’s chair comes with a control console that swings out of the way to allow her to come up close to tables and counters, but she has problems applying enough force to manually position it.

Sadly, [Rhonda]’s insurance doesn’t cover a commercial solution to her problem. But The Boston Home has a fully equipped shop to …read more http://pje.fyi/Q66WRl

The Physics of Healing: Radiation Therapy

Few days are worse than a day when you hear the words, “I’m sorry, you have cancer.” Fear of the unknown, fear of pain, and fear of death all attend the moment when you learn the news, and nothing can prepare you for the shock of learning that your body has betrayed you. It can be difficult to know there’s something growing inside you that shouldn’t be there, and the urge to get it out can be overwhelming.

Sometimes there are surgical options, other times not. But eradicating the tumor is not always the job of a surgeon. Up to …read more http://pje.fyi/Q4JQVN
