DIY masks and shields

morreale Tuesday 07 of April, 2020
The high demand and shortage of surgical and N95 mask has lead many group to improvise and build their own. It's not clear who will be accepting DIY shields and masks since the mask and shields haven't been qualified. The links below are a random sample of the active projects.

Social Distancing Score Board

morreale Monday 30 of March, 2020
Unacast has created an interactive Social Distancing Score Board using data from the Johns Hopkins Git repository. It shows the reduction in travel by state and county. Our state received a score of A, but we seem to have had a spike of infections.


The public use of mask hypothesis

morreale Monday 30 of March, 2020
In their blog, Public use of masks to control the coronavirus pandemic researchers at the University of Bath hypothesize that public uses of masks may help control the coronavirus pandemic. The idea is that masks help reduce the spread of the virus by reducing the amount of droplets expelled and inhaled. The blog notes that surgical and N95 masks appear to be effective. Non-medical masks appear to be effective as well according to the blog. The research found that the effectiveness of improvised masks are unknown because of flawed study controls.


In another older study, A cluster randomised trial of cloth masks compared with medical masks in healthcare workers found that infection rates for healthcare workers using cloth masks were higher, than the infection rates for worker using medical masks. The study concluded that cloth masks are not suitable for healthcare workers.

Help simulate COVID-19 protein folding

morreale Tuesday 24 of March, 2020
Folding@home (FAH or F@h) is a distributed computing project for simulating protein dynamics, including the process of protein folding and the movements of proteins implicated in a variety of diseases. Folding@home is working to start simulations of the COVID-19 protein. The simulations are run on a volunteer network of distributed computers. Volunteers install an app on their computer and the simulation runs when the users computer is idle. To support the effort, download, install the program, and configure it to allocate computer resources as desired. The app is available for Windows, Linux, and macOS.

Linus Tech Tips has a video Here's How YOU Can Help Find a Cure for COVID-19! that shows them setting up a machine to run the Folding@home.

Open ventilator and other coronavirus projects

morreale Friday 20 of March, 2020
A number of groups are working on open ventilators and other hardware projects to contribute to the shortages of medical supplies, equipment, and Personal Protection Equipment due to the coronavirus COVID-19. I heard an estimate today on the news that 3 billion masks will be needed in the US, for example. The scale of the impact of the coronavirus is hard to fathom. A short list of projects are shown below.
