    Example repo: https://github.com/valdanylchuk/breezydemo The underlying ESP-IDF component: https://github.com/valdanylchuk/breezybox It is something like Raspberry Pi, but without the overhead of a full server-grade OS. It captures a lot of the old school DOS era coding experience. I created a custom fast text mode driver, plan to add VGA-like graphics next. ANSI text demos run smooth, as you can see in the demo video featured in the Readme. App installs also work smoothly. The first time it installed 6 apps from my git repo with one command, felt…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.
