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!
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.
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.
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.
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.
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!
One important thing to set up when using these drivers is the motor current limit. This is especially important when you’re using a higher input voltage than what the motor is rated for. Using a higher voltage generally enables you to get more torque and a faster step speed, but you’ll need to actively limit the amount of current flowing through the motor coils so that you don’t burn your motor out.
We're popping in today to bring your attention to our LinkedIn page, where you can see Nathan talk about machine learning, artificial intelligence, tinyML, data logging with the Artemis OpenLog, and the origins of SparkFun with Wisse Hettinga at the IoT Radar.
One of our fave makers, Wayne fromDevscover, got a bit sick of losing at Scrabble (and his girlfriend was likely raging at being stuck in lockdown with a lesser opponent). So he came up with a Raspberry Pi–powered solution!
Using a Raspberry Pi High Quality Camera and a bit of Python, you can quickly figure out the highest-scoring word your available Scrabble tiles allow you to play.
Raspberry Pi 3B
Raspberry Pi High Quality Camera
Power supply for the touchscreen and Raspberry Pi
You don’t have to use a Raspberry Pi 3B, but you do need a model that has both display and camera ports. Wayne also chose to use an official Raspberry Pi Touch Display because it can power the computer, but any screen that can talk to your Raspberry Pi should be fine.
Firstly, the build takes a photo of your Scrabble tiles using raspistill.
Next, a Python script processes the image of your tiles and then relays the highest-scoring word you can play to your touchscreen.
The key bit of code here is twl, a Python script that contains every possible word you can play in Scrabble.
From 4.00 minutes into his build video, Wayne walks you through what each bit of code does and how he made it work for this project, including how he installed and used the Scrabble dictionary.
Fellow Scrabble-strugglers have suggested sneaky upgrades in the comments of Wayne’s YouTube video, such having the build relay answers to a more discreet smart watch.
No word yet on how the setup deals with the blank Scrabble tiles; those things are like gold dust.
