Adafruit’s privacy-preserving contact tracing app … Apple and Google is also doing something @adafruit @apple @google (UPDATE 4/23/2020)


Update: 4/23/2020, The Adafruit privacy-respecting contact tracing app was deployed at 4:21pm ET today April 23rd, 2020 to a small number of essential-worker team members and is being tested now please DM us on Twitter or email us, trying to add more features, we can work together …

Adafruit has been working on an employee / team member only privacy-preserving contact tracing app for a few weeks now. We saw the app in Singapore and assumed Google, Facebook, Apple, etc. would be making an app and we wanted to make sure we had something that worked for our needs, and if there are ways to make it work with the bigger companies, we’ll see what makes sense.

Our app is privacy first for our team. The data is not shared with anyone unless it needs to be shared (for example, during the time we have essential work, if someone gets ill or tests positive for COVID we could then have a log of locations and sent to the team member’s own email address if needed).

We think companies will want to have their own app for their own teams for contact tracking with a privacy policy that works for them. We’re an open-source company that has an IoT bill of rights for our users and ourselves, so we’ll be going above and beyond to make this work for us in the most private, safe way. It’s in super-alpha now, so we’ll post more as we test it out.

As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email to let us know about your post so we can blog it up here.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
