Stay Informed: How to Pull your Own COVID-19 Data


Tom Nardi wrote a guide on hackaday for pulling and scraping raw data about COVID19 from multiple data sources. If you’re building a way to monitor the total number of cases in your state or country, this guide provides reputable data sources along with Python code snippets. -HackaDay

Upcycled Cassette IoT Display


Martin Mander, aka Old Tech. New Spec, gives life to obsolete technologies, usually by sticking a computer in them and connecting them to the internet. In this example of the upcycler’s craft, he’s turned a cassette (an ancient, rubbish way of recording music) into an IoT notification reader. - Adafruit

Support Adafruit


Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
