$55 Watchy Smartwatch Combines ESP32 WiFi & Bluetooth SoC with E-ink Display

Watchy ESP32 E-ink Smartwatch

SQFMI has designed a (mostly) open-source hardware smartwatch based on an ESP32-S wireless module for WiFI and Bluetooth connectivity, and equipped with an E-ink display of 200×200 resolution. Watchy also comes with a BMA423 accelerometer, four buttons, a DS3231 real-time clock, and a vibration motor. The watch should last around 2 weeks on a charge. I mentioned the watch is “mostly” open source hardware because while the GERBER files, bill of materials (BoM) and the PDF schematics have been released on Github, the KiCAD schematics and PCB layout files have not so far. That still means you can understand the design, repair the design, or even make your own, but if you intended in modifying the design, you’d have some more work to do. Tom Fleet, writing for Hackster.io, does go through different sections of the schematics and explain what they do. One the software side, the watch can be programmed with MicroPython or Arduino, and the Arduino library, as …

Bangle.js is an Hackable, Open Source JavaScript and TensorFlow-driven Smartwatch (Crowdfunding)

Espruino brought JavasScript to the Microcontroller, now Bangle.js is bringing Javascript plus TensorFlow Lite to your smartwatch. There has been some movement by some developers that says that JavaScript should be used for everything, even though I find that idea ridiculous, I still find JavaScript a fascinating language. The NeaForm Research team and Gordon Williams (the brain behind Espruino) have all teamed up in launching Bangle.js Smartwatch. Bangle.js isn’t your ordinary smartwatch, at the heart of it is the open-source ecosystem. JavaScript plus TensorFlow Lite and of course, a cool looking Smartwatch is what Bangle.js is offering.

PineTime is a $25 Smartwatch / Companion for PinePhone Linux Phone

PineTime

We’ve recently seen Linux smartphones are coming in a few weeks or months, but the $150 PinePhone may not come alone, and soon be joined by a $25 companion, namely PineTime smartwatch. That’s what we learned through a tweet by Pine64 explaining the PineTime is a Linux smartphone companion that can run FreeRTOS or Arm Mbed operating systems.  It will be a side-project however, and the focus is still on PinePhone and Pinebook Pro, meaning it will take a while depending on the level of community engagement. Available information is limited to the discussion in the tweet at this stage, but we do know the watch will be made of zinc alloy &  plastic, come with a charging dock, a 20 mm wristband, an heart-rate monitor and last several days on a charge. We’ve also seen people interested in porting ZephyrOS to the watch, and others would like to make it work with Android and/or iOS smartphones. Development kits should …
