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. Bangle.js was launched at the recently concluded NodeConf EU conference, and the goal is to bootstrap an Open Health Platform hopefully. NodeWatch is the specific implementation of Bangle.js for NodeConf EU 2019, co-developed by Espruino and NearForm Research. This project has the potential to bootstrap a community-driven open health platform where anyone can build or use any compatible device and everyone owns their …

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 …

This Open Source Hardware Smartwatch Project is Fully Documented

Open Source Hardware Smartwatch

While there are plenty of smartwatches available, they may not perfectly match your requirements and needs. But did you wake up one day and just decided to build your own? Probably not. But Samson March had his own plans, and as a professional electrical engineer and product designer, he decided to start a smartwatch project during his spare time. What makes it really interesting is that he provided a long list of photos and short videos explaining in details the process, and open-sourced all materials from hardware design files, to firmware source code, and 3D print files for the body and charging dock! The OSHW watch does not have a name (yet) and features the following hardware: Wireless MCU – Dialog Semiconductor DA14683 Arm Cortex-M0 microcontroller up to 96 MHz 128KB RAM, 128KB ROM, 64KB OTP, and with Bluetooth 5.0 connectivity Storage – 128 Mbit SPI flash Display – 1.3″ 240 x 240 pixel LCD display (non-touch) Misc – Vibration …

Nubia–α Wearable Smartphone is a Smartwatch with a Long Curved Display

Nubia alpha wearable smartphone

We have smartphones, we have smartwatches. and we have… Nubia-α that is something in between, and which the company (Nubia) promotes as a “wearable smartphone”. The device comes with a long curved display, and you’d wear it around your wrist just like a watch with access to fitness apps, and music, but just like in a phone, you could make phone calls and send SMS thanks to 4G connectivity, as well as taking selfies or making video calls with its built-in camera. We don’t have the specifications yet, but the thing is real as it was showcased at IFA 2018, although for the eyes only, i.e. no hands-on or even touching the Nubia-α. Engadget reported about the device, and while the reporter clearly did not like the largish camera on the side, she seems impressed by the brightness and colors coming out of the Flex OLED display. The watch / phone? can also be used for payment, I suppose via …

$100 GLIGO E-Ink Smartwatch Promises “2-Year Battery Life” (Crowdfunding)

Wearables are useful little devices, but many of them suffer from short battery life, and in my case at least, I forget to charge mine from time to time. So when I saw GLIGO E-Ink smartwatch promising 2-year battery life on a charge, it caught my eyes. But then looking into the details, it looks like battery life is really 6 months unless you don’t plan on using the display: We adopted an energy-efficient dual-core design:the quartz core has a battery life of up to two years, e-ink screen has a battery life of up to 180 days. Six months is not that bad either, so let’s still have a look.
