A project that I’ve been working on (and off) for while has been the titular tweeting webcam photos with a ZYBO.
This turned out to be a great project, but much more challenging than expected. It was definitely a great learning experience! If you start this project from scratch, you’ll learn about booting Ubuntu on the ZYBO, Twitter APIs, Python, using webcams, and other EECS topics.
