Shockingly, DARPA’s Brain Stimulator Might Not be Complete Nonsense

Where does your mind jump when you hear the mention of electroshock therapy? The use of electrical current to treat various medical conditions has a long and controversial history. Our fascination with the medical applications of electricity have produced everything from the most alarming of patent medicines to life-saving devices like pacemakers and the Automatic External Defibrillator.

The oldest reference I could find is the use of the torpedo fish to allegedly cure headaches, gout, and so on in 43 CE. Incidentally, Torpedo torpedo is an awesome species name.

Much more recently, there has been interest in transcranial direct current …read more

Turn Medical Imaging From 2D Into 3D With Just $10

One of the modern marvels in our medical toolkit is ultrasound imaging. One of its drawbacks, however, is that it displays 2D images. How expensive do you think it would be to retrofit an ultrasound machine to produce 3D images? Try a $10 chip and pennies worth of plastic.

While — of all things — playing the Wii with his son, [Joshua Broder, M.D], an emergency physician and associate professor of surgery at [Duke Health], realized he could port the Wii’s gyroscopic sensor to ultrasound technology. He did just that with the help of [Matt Morgan, Carl Herickhoff and Jeremy …read more

Game Boy Advance Hiding In a Medical Device

It turns out that medical manufacturers also do hacking once in a while. [JanHenrikH] recently tweeted a photo of an ECG-Trigger-Unit that he’d opened up. Inside he found that the LCD screen was that of a Game Boy Advance (GBA) and the reason he could tell was that the screen’s original case was still there, complete with GAME BOY ADVANCE SP written on it.

In the manufacturer’s defense, this device was likely made around the year 2000 when gaming products were some of the best sources for high speed, high quality, small LCD displays.  This design document for a portable …read more

Synthesizing Daraprim to Beat Price Gougers

Drugs are used the world over to treat disease. However, from time to time, the vagaries of market economics, or unscrupulous action, can radically increase the price of otherwise cheap pharmaceuticals far beyond the reach of the average person. This was the case with Pyrimethamine (sold as Daraprim), which is used to treat toxoplasmosis and malaria, among other users. With the price skyrocketing from $13 to $750 a tablet in the US in 2015, [NurdRage] decided to synthesize the drug on their own. (If you missed the background hubbub, search for “Martin Shkreli”.)

The video linked covers the final synthesis, …read more

Magnet Implants, Your Cyborg Primer

What would you do to gain a sixth sense? Some of us would submit to a minor surgical procedure where a magnet is implanted under the skin. While this isn’t the first time magnet implants have been mentioned here on Hackaday, [The Thought Emporium] did a phenomenal job of gathering the scattered data from blogs, forum posts, and personal experimentation into a short video which can be seen after the break.

As [The Thought Emporium] explains in more eloquent detail, a magnet under the skin allows the implantee to gain a permanent sense of strong magnetic fields. Implantation in a …read more

Hackaday Prize Entry: Remote Control by Head Gestures

Some people may think they’re having a bad day when they can’t find the TV remote. Yet there are some people who can’t even hold a remote, let alone root around in the couch cushions where the remote inevitably winds up. This entry in the Assistive Technologies phase of the 2017 Hackaday Prize seeks to help such folks, with a universal remote triggered by head gestures.

Mobility impairments can range from fine motor control issues to quadriplegia, and people who suffer from them are often cut off from technology by the inability to operate devices. [Cassio Batista] concentrated on controlling …read more

Hackaday Prize Entry: Fighting Dehydration One Sip at a Time

Humans don’t survive long without water, and most people walk around in a chronic state of mild dehydration even if they have access to plenty of drinking water. It’s hard to stay properly hydrated, and harder still to keep track of your intake, which is the idea behind this water-intake monitoring IoT drinking straw.

Dehydration is a particularly acute problem in the elderly, since the sense of thirst tends to diminish with age. [jflaschberger]’s Hackaday Prize entry seeks to automate the tedious and error-prone job of recording fluid intake, something that caregivers generally have to take care of by eyeballing …read more

Detecting Dire Diseases – with a Selfie?

They say the eyes are the windows to the soul. But with a new smartphone app, the eyes may be a diagnostic window into the body that might be used to prevent a horrible disease — pancreatic cancer. A research team at the University of Washington led by [Alex Mariakakis] recently described what they call “BiliScreen,” a smartphone app to detect pancreatic disease by imaging a patient’s eyes.

Pancreatic cancer is particularly deadly because it remains asymptomatic until it’s too late. One early symptom is jaundice, a yellow-green discoloration of the skin and the whites of the eyes as the …read more

Movie Encoded in DNA is the First Step Toward Datalogging with Living Cells

While DNA is a reasonably good storage medium, it’s not particularly fast, cheap, or convenient to read and write to.

What if living cells could simplify that by recording useful data into their own DNA for later analysis? At Harvard Medical School, scientists are working towards this goal by using CRISPR to encode and retrieve a short video in bacterial cells.

CRISPR is part of the immune system of many bacteria, and works by storing sequences of viral DNA in a specific location to identify and eliminate viral infections. As a tool for genetic engineering, it’s cheaper and has fewer …read more

Best Product Entry: A HSDK for Ultrasound Imaging

As an entry into this year’s Best Product portion of the Hackaday Prize, [kelu124] is developing a hardware and software development kit for ultrasound imaging.

Ultrasound is one of the primary tools used in modern diagnostic medicine. Head to the doctor with abdominal pain, and you can bet you’ll be seeing the business end of an ultrasound system. While Ultrasound systems have gotten cheaper, they aren’t something everyone has in the home yet.  [kelu124] is working to change that by building a hardware and software development kit which can be used to explore ultrasound systems. This isn’t [kleu124’s] first rodeo. …read more
