About Me
Hi, I'm Dolphin Liu 👋
I'm a systems engineer and hobbyist maker–educator based in Guangzhou, China. I'm also an ambassador for the MicroBlocks open-source project.
In my spare time I volunteer at nearby schools, where I teach kids to use open-source hardware like the ESP32 and open-source software like MicroBlocks to create programmable STEM projects.
MicroBlocks is an open-source, graphical block-based hardware-programming platform similar to Scratch. I'm currently writing a book titled MicroBlocks STEM Programming, which I hope to publish in 2026.
Here is my photo at Shenzhen Maker Faire 2025. It was a great experience where I met lots of maker fans and swapped ideas about open-source hardware and creative STEM projects.
