Maker Therapy Joins The Fight Against COVID-19

April 21, 2020 by Orlando Hoilett No comments

We love talking about makerspaces here at Hackaday. We love hearing about the camaraderie, the hacks, the outreach, the innovation, everything. Even more, we love seeing all the varying forms that makerspaces take, either in the hacks they create, the communities they reach out to, and especially their unique environments.

Recently, we came across Maker Therapy, a makerspace right inside a children’s hospital. Now, we’ve heard about hospital makerspaces here on Hackaday before, but what makes Maker Therapy particularly unique is it’s the first hospital makerspace that gives patients the opportunity to innovate right in the pediatric setting.

Inspired by patients and founded by Dr. Gokul Krishnan, Maker Therapy has been around for a few years now but recently popped up on our radar due to their unique position on the frontlines of the COVID-19 pandemic. As a makerspace located right inside a hospital, Maker Therapy is in the unique position to be the hospital’s very own rapid prototyping unit. Using 3D printing and other tools, Maker Therapy is able to make face shields and other important PPE right where they are needed the most.

Here at Hackaday, we salute and give our eternal gratitude to all the health care professionals fighting for our communities. Maybe some of your hacks and other designs could be used by initiatives like Maker Therapy? Until then, stay home and stay safe Hackaday. The only way we’ll get through this is together.

Google And Apple Reveal Their Coronavirus Contact Tracing Plans: We Kick The Tires

April 16, 2020 by Elliot Williams 85 Comments

Google and Apple have joined forces to issue a common API that will run on their mobile phone operating systems, enabling applications to track people who you come “into contact” with in order to slow the spread of the COVID-19 pandemic. It’s an extremely tall order to do so in a way that is voluntary, respects personal privacy as much as possible, doesn’t rely on potentially vulnerable centralized services, and doesn’t produce so many false positives that the results are either ignored or create a mass panic. And perhaps much more importantly, it’s got to work.

Slowing the Spread

As I write this, the COVID-19 pandemic seems to be just turning the corner from uncontrolled exponential growth to something that’s potentially more manageable, but it’s not clear that we yet see an end in sight. So far, this has required hundreds of millions of people to go into essentially voluntary quarantine. But that’s a blunt tool. In an ideal world, you could stop the disease globally in a couple weeks if you could somehow test everyone and isolate those who have been exposed to the virus. In the real world, truly comprehensive testing is impossible, and figuring out whom to isolate is extraordinarily difficult due to two factors: COVID-19 has a long incubation period during which it is nonetheless transmissible, and some or even most people don’t know they have it. How can you stop what you can’t see, and even when you can detect it, it’s a week too late?

One promising approach is to isolate those people who’ve been in contact with known cases during the stealth contagion period. To do this is essentially to keep a diary of everyone you’ve been in contact with for the last week or two, and then if you eventually test positive for COVID-19, alert them all so that they can keep from infecting others even before they test positive: track and trace. Doctors can do this by interviewing patients who test positive (this is the “contact tracing” we’ve been hearing so much about), but memory is imperfect. Enter a technological solution.

COVID-19 And The State Of The Climate

April 10, 2020 by Lewin Day 48 Comments

The novel coronavirus sweeping the globe has led governments to institute widespread quarantines to stem the spread. Many industries have slowed production or shutdown entirely, and economic activity has slowed to a crawl. This has naturally led to a sudden reduction in greenhouse gas emissions. But how great will the effect be, and will it buy us any real time?

On The Ground

In the wake of COVID-19, good news stories have sprung up as people look for a silver lining. Unfortunately, these stories aren’t always true. There aren’t dolphins in the waters of Venice, though the water has cleared due to reduced boat activity. And drunken elephants did not begin roaming the mountains of China.

Despite this, there have been notable reductions in emissions in several areas due to government-mandated lockdowns. Northern Italy is seeing a much lower concentration of nitrogen dioxide, likely due to reduced industrial and vehicular activity. Carbon monoxide levels have similarly dropped in New York, while China has seen its carbon emissions temporarily drop by a full 25%.

On the surface of it, these are all promising numbers. Many are cautiously optimistic that this could be a major development to help stave off the worst of climate change for a little longer. Nonetheless, it’s early days yet, and what happens after the crisis passes is just as important as what’s happening now.

Ultrasonic Sensor Helps You Enforce Social Distancing

April 9, 2020 by Erin Pinheiro 22 Comments

If you’re going outside (only for essential grocery runs, we hope) and you’re having trouble measuring the whole six feet apart from other people deal by eye, then [Guido Bonelli] has a solution for you. With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

As simple as this project may sound like for anyone who has a bunch of these little Arduino-compatible modules lying around and has probably made something similar to this in their spare time, there’s one key component that gives it an extra bit of polish. [Guido] found out how intermittent the reliability of the ultrasonic sensor was and came up with a clever way to smooth out its output in order to get more accurate readings from it, using a bubble sort algorithm with a twist. Thirteen data points are collected from the sensor, then they are sorted in order to find a temporal middle point, and the three data points at the center of that sort get averaged into the final output. Maybe not necessarily something with scientific accuracy, but exactly the kind of workaround we expect around these parts!

Projects like these to help us enforce measures to slow the spread of the virus are probably a good bet to keep ourselves busy tinkering in our labs, like these sunglasses which help you remember not to touch your face. Make sure to check out this one in action after the break!

Brainstorming COVID-19 Hack Chat

April 6, 2020 by Dan Maloney 15 Comments

Join us on Wednesday, April 8 at noon Pacific for the Brainstorming COVID-19 Hack Chat!

The COVID-19 pandemic has been sweeping across the globe now for three months. In that time it has encountered little resistance in its advances, being a novel virus with just the right mix of transmissibility and virulence that our human immune systems have never encountered. The virus is racking up win after win across the world, crippling public health and medical systems, shutting down entire economies, and forcing billions of people into isolation for the foreseeable future.

While social distancing is certainly an effective way to limit the spread of the disease, it feels more like hiding than fighting. Bored and stuck at home, millions of fertile minds are looking for an outlet for this frustration, a more affirmative way to fight the good fight and build solutions that the world sorely needs. And thus we’ve seen the outpouring of designs, ideas, and prototypes of everything from social distancing helpers to personal protective equipment (PPE) hacks.

In this Hack Chat, we’ll try to provide a framework around which hackers can start to turn their ideas into COVID-19 solutions. There are a ton of problems right now, but the most acute and most approachable seem to revolve around making sure healthcare providers have the PPE they need to do their job safely. Hacking at the edges of managing social distancing seems doable, too, both in terms of helping people keep a healthy distance from each other and in managing the isolation that causes. And let’s not forget about managing boredom; idle hands lead to idle minds, and staying healthy mentally is just as important as good handwashing and nutrition.

Join us on Wednesday for this group-led Hack Chat and bring your best ideas for attacking COVID-19 head-on.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, April 8 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.

Cellular Tracking Used During COVID-19 Pandemic

April 3, 2020 by Lewin Day 43 Comments

As most in the technology community know, nation states have a suite of powerful tools that can be used to trace and monitor mobile phones. By and large, this comes up in discussions of privacy and legislation now and then, before fading out of the public eye once more. In the face of a global pandemic, however, governments are now using these tools in the way many have long feared – for social control. Here’s what’s happening on the ground.

The Current Situation

With COVID-19 sweeping the globe, its high level of contagiousness and rate of hospitalizations has left authorities scrambling to contain the spread. Unprecedented lockdowns have been put in place in an attempt to flatten the curve of new cases to give medical systems the capacity to respond. A key part of this effort is making sure that confirmed cases respect quarantine rules, and isolate themselves to avoid spreading the disease. Rules have also been put in place in several countries where all overseas arrivals must quarantine, regardless of symptoms or status.

Professional Ventilator Design Open Sourced Today By Medtronic

March 30, 2020 by Bob Baddeley 116 Comments

Medical device company Medtronic released designs for one of their ventilators to open source for use in the COVID-19 pandemic. This is a laudable action, and there is plenty to glean from the specs (notable is that the planned release is incomplete as of this writing, so more info is on the way). Some initial reactions: medical devices are complicated, requirements specifications are enormous, the bill of materials (BOM) is gigantic, and component sourcing, supply chain, assembly, and testing are just as vital as the design itself.

The pessimist in me says that this design was open sourced for two reasons; to capitalize on an opportunity to get some good press, and to flex in front of the DIY community and convince them that the big boys should be the ones solving the ventilator shortage. The likelihood of anyone actually taking these specs and building it as designed are essentially zero for a variety of reasons, but let’s assume their intent is to give a good starting point for newer changes. The optimist in me says that after what happened to California over the weekend with 170 ventilators arriving broken, it might be nice to have open designs to aid in repair of existing non-functioning ventilators.

The design details released today are for their PB560 model, which was originally launched in 2010 by a company called Covidien, before it merged with Medtronic, so we’re already starting with a device design that’s a decade old. But it’s also a design that has proven itself through widespread use, and this data dump gives us a great look at what actually goes into one of these machines. Let’s take a look.
