Teardown Session 4: E-paper and smart watches with Wailun from Watchy

by Crowd Supply

In this episode of the Teardown Sessions, Crowd Supply’s Helen Leigh unboxes and assembles a Watchy while chatting with Wailun of SQFMI. Join them as they discuss smart watches, e-paper, DIY displays, PCB design and how he successfully raised $220,000+ by crowdfunding his open source hardware designs.

About Wailun

Wailun is the engineer behind Watchy, a beautiful, fully open source and customizable e-paper watch that raised over $220,000 on Crowd Supply. Join the conversation as we dive into their tech, and nerd out about e-paper and other "alternative" display technology We also look at some of the things the SQFMI team did beyond just engineering to make their first crowdfunded product such a success.

About Watchy

Watchy’s E-Ink display delivers an always-on, beautiful, crisp image clearly visible under bright sunlight, and requires no power between updates. Watchy has both Wi-Fi and Bluetooth LE connectivity, allowing it to connect with internet APIs (e.g., weather, news, traffic, maps, Spotify, etc.), as well as Bluetooth LE enabled devices. Watchy uses the ESP32, so you can choose to customise it using Arduino, Micropython, ESP-IDF, or Zephyr-RTOS.
