This project comes from a joke that has been circulating the internet, “Your server is made of potatoes, right?”
I finished the joke with my friend.
First, we need a full-power potato batteries.
This is followed by a low-power system including a low-power processor, an Eink display, and a low-power Bluetooth gateway.
Then designed a PCB for it.
Testing.
This story ended up providing the source of the idea for the 2022 Tsinghua University admissions video.
