This is my first time working with a microcontroller, and it's been a lot of fun.
I gave my espresso machine a brain. I particularly like the animated splash screen, which starts out black and fills up in a satisfyingly glitchy way: https://github.com/flowerysong/ESPress0x20/blob/5b6b71ee653496ffb639b069b10bea96112f9484/ESPress0x20.ino#L194-L219
In 2021 I read 57,174 pages across 213 books. (Plus or minus a few hundred pages, because Goodreads page counts aren’t always accurate.)
Love it when you help someone write code to convert a really terrible input format that you presume is from an external source into a data structure, and then the next day find out they were creating that data in the previous step and had full control over the format. So they can just directly output the structured data they needed, instead of parsing positional fields.
