#FreePCB via Twitter to 2 random RTs

via Dangerous Prototypes

Every Tuesday we give away two coupons for the free PCB drawer via Twitter. This post was announced on Twitter, and in 24 hours we’ll send coupon codes to two random retweeters. Don’t forget there’s free PCBs three times a every week:

  • Hate Twitter and Facebook? Free PCB Sunday is the classic PCB giveaway. Catch it every Sunday, right here on the blog
  • Tweet-a-PCB Tuesday. Follow us and get boards in 144 characters or less
  • Facebook PCB Friday. Free PCBs will be your friend for the weekend

Some stuff:

  • Yes, we’ll mail it anywhere in the world!
  • Check out how we mail PCBs worldwide video.
  • We’ll contact you via Twitter with a coupon code for the PCB drawer.
  • Limit one PCB per address per month please.
  • Like everything else on this site, PCBs are offered without warranty.

We try to stagger free PCB posts so every time zone has a chance to participate, but the best way to see it first is to subscribe to the RSS feed, follow us on Twitter, or like us on Facebook.

Summer Camp – SparkFun Style

via SparkFun: Commerce Blog

We know a lot of summer camps, trips and activities are up in the air, if not downright canceled this year. Not to worry - we’ve got some of your typical summer camp activities covered, with an electronics twist. Check out this summer’s activity schedule, and let’s have some fun!

Wooden trail sign with SparkFun Summer Camp and deal dates

Our summer camp schedule includes:

  • E-textiles: Kick your arts and crafts game up a notch by adding lights and sound to your projects - we see that rad patch you’re working on! (If you end up making a sweet summer camp patch, we’d love to see it! Share on social media and tag @sparkfun.)
  • GPS: Hiking and exploring nature can be tricky if you’re somewhere unfamiliar. Learn more about GPS and try making your own system.
  • Robotics: You could play a classic summertime sport or game – or you could build a robot and teach it to play with you (very slow, two-player tag, anyone?)!
  • Machine Learning: Ever tried to memorize the plants, bugs and animals you might meet in your local great outdoors? Maybe it’s time to have machine learning lend you a hand, so you don't learn the difference between poison ivy and Boston ivy the hard way.

Camp will kick off Thursday evening, July 2nd, and end on Friday, July 31, at 11:59 p.m. MDT. Our special summer camp page will be live on Thursday evening, and each week will have activities, projects and information to get you started on the different topics. While we’re at it, each theme will feature some sort of surprise, because who doesn’t love a sale? Check Thursday evenings for the latest surprise! Please note that we will be closed in observance of the July 4th holiday on Friday, July 3rd.

We’d love to see the projects that you create this summer! Please share with us on social media by tagging us on your post.

Volunteer your Raspberry Pi to IBM’s World Community Grid

via Raspberry Pi

IBM’s World Community Grid is working with scientists at Scripps Research on computational experiments to help find potential COVID-19 treatments. Anyone with a Raspberry Pi and an internet connection can help.

Why is finding potential treatments for COVID-19 so important?

Scientists all over the globe are working hard to create a vaccine that could help prevent the spread of COVID-19. However, this process is likely to take many months — or possibly even years.

In the meantime, scientists are also searching for potential treatments for the symptoms of COVID-19. A project called OpenPandemics – COVID-19 is one such effort. The project is led by researchers in the Forli Lab at Scripps Research, who are enlisting the help of World Community Grid volunteers.

What is World Community Grid and how does it work? 

World Community Grid is an IBM social responsibility initiative that supports humanitarian scientific research. 

Image text reads: Accelerate research with no investment of time or money. When you become a World Community Grid volunteer, you donate your device's spare computing power to help scientists solve the world's biggest problems in health and sustainability.

As a World Community Grid volunteer, you download a secure software program to your Raspberry Pi, macOS or Windows computer, or Android device. This software program (called BOINC) is used to run World Community Grid projects, and is compatible with the Raspberry Pi OS and most other operating systems. Then, when your device is not using its full power, it automatically runs a simulated experiment in the background that will help predict the effectiveness of a particular chemical compound as a possible treatment for COVID-19. Finally, your device automatically returns the results of the completed simulation and requests the next simulation.

Over the course of the project, volunteers’ devices will run millions of simulations of small molecules interacting with portions of the virus that causes COVID-19. This is a process known as molecular docking, which is the study of how two or more molecules fit together. When a simulated chemical compound fits, or ‘docks’, with a simulation of part of the virus that causes COVID-19, that interaction may point to a potential treatment for the disease.

An image of a calendar with the text: Get results that matter. As a World Community Grid volunteer, your device does research calculations when it's idle, so just by using it as. you do every dat you can help scientists get results in months instead of decades. With your help, they can identify the most important areas to study in the lab, bringing them one step closer to discoveries that save lives and address global problems.

World Community Grid combines the results from your device along with millions of results from other volunteers all over the world and sends them to the Scripps Research team for analysis. While this process doesn’t happen overnight, it accelerates dramatically what would otherwise take many years, or might even be impossible.

OpenPandemics – COVID-19 is the first World Community Grid project to harness the power of Raspberry Pi devices, but the World Community Grid technical team is already working to make other projects available for Raspberry Pi very soon.

Getting ready for future pandemics

Scientists have learned from past outbreaks that pandemics caused by newly emerging pathogens may become more and more common. That’s why OpenPandemics – COVID-19 was designed to be rapidly deployed to fight future diseases, ideally before they reach a critical stage.

Scientists are using World Community Grid to accelerate the search for treatments to COVIS-19. The tools and techniques the scientists develop to fight COVID-19 could be used in the future by all researchers to help more quickly find treatments for potential pandemics

To help address future pandemics, researchers need access to swift and effective tools that can be deployed very early, as soon as a threatening disease is identified. So, the researchers behind OpenPandemics – COVID-19 are creating a software infrastructure to streamline the process of finding potential treatments for other diseases. And in keeping with World Community Grid’s open data policy, they will make their findings and these tools freely available to the scientific community. 

Join a global community of science supporters

World Community Grid is thrilled to make OpenPandemics – COVID-19 available to everyone who wants to donate computing power from their Raspberry Pi. Every device can play a part in helping the search for COVID-19 treatments. Please join us!

Name that Ware, June 2020

via Hacking – bunnie's blog

The Ware for June 2020 is shown below.

Thanks to Bob Parker for contributing this ware.

And thanks to everyone who has been submitting guest wares. Since March I literally have not moved outside a circle with a 3-km (2-mi) radius, and there’s currently no end in sight to that trend. I appreciate the interesting diversity of wares being sent my way, please keep them coming!

On that note, if you have a travel bag of gadgets that has been collecting dust for the past few months, don’t forget to check the condition of their batteries; deeply discharged lithium batteries are never a good thing.

Winner, Name that Ware May 2020

via Hacking – bunnie's blog

The Ware for May 2020 is a Furano AIS Receiver, model FA-30. Gratz to willmore for nailing it! email me for your prize. This board has a very made-in-Japan feel to it. I can’t put my finger on exactly what makes me think that, but there is a certain style to the routing choices, and also the silkscreen color and font is common to PCBs from that corner of the world. I wouldn’t be surprised if a large portion of the PCB designers in Japan could trace their best practices and toolkit defaults back to just one or two large companies.
