Global parts shortage, amirite?! Say you reeeeeally need to get your hands on a Raspberry Pi single board computer. They're in short supply, but they are still in stock at irregular intervals. We at Adafruit have been releasing them in small batches as we get them in. They usually sell out in a few minutes. So, this project is designed to help you know the moment they are available. This is the RPi Stock Alert Alarm!

This project uses a Feather ESP32-S2 TFT (hey, it would be pretty mean if we made this project using a Raspi!) to check the rpilocator.com Twitter feed, searching for new Tweets with the keyword "Adafruit". When it finds one, that means there is most likely a fresh batch for sale. This info is displayed on the TFT (including which model of RPi it is), and even better, a bright red spinning light and siren goes off to get your attention!
