ESticky V2 — Sticky Note thông minh hơn

Last year, I designed a small gadget called eSticky: a compact, paperless way to keep your thoughts organised, and it was a great success. The project garnered a lot of attention, showing its potential for further development. As a result, I created a new version with enhanced software and hardware.

Introducing eSticky V2.

This device can serve multiple functions, including a clock, a to-do list, a live YouTube subscriber counter, and a countdown timer for your graduation. Additionally, it can display many other options. We have developed a fully custom-made PCB featuring the XIAO ESP32S3, larger batteries, and a 3D-printed desktop enclosure. For this project, we are still using the 2.9-inch e-ink display from SeedStudio.

On the software side, eSticky V2 is fully compatible with SenseCraft HMI—a cloud-based, no-code platform that allows you to design interfaces using easy drag-and-drop tools.

Let's take a look at how I built one.
