Len Popp was recently on the Adafruit Show and Tell program with this interesting project.
I built a device to warn of potential Earth-threatening asteroids. It monitors NASA JPL’s Sentry web service using a Raspberry Pi Pico W and CircuitPython.
Periodically, an HTTP request is sent over wifi to the Sentry web service to query for the asteroids with the highest threat levels. Typically 6 or 7 objects are returned.
The Pico W connects to the internet via wifi, and it is also connected to an OLED display, an I2S audio amplifier, and a pushbutton. A PiCowbell proto board hooks things together.
Check out the whole project here and the code on GitHub.
