Energous Launches WattUp Smart Glasses Developer Kit for Customer Product Designs
Near-field wireless charging technology has the potential to disrupt the consumer electronics industry, but its adoption has been limited. Energous wireless charging technology WattUp has promised to change that narrative by making it possible to charge devices mid-field (on the desk) or far off (in the room. Aside from the distance challenge in wireless charging, one other major issue is the fact that there are few deployments with them. Only a few devices have wireless charging incorporated. Energous is hoping to change that as well with the launch of the WattUp Smart Glasses Developer Kit, which is tailored for custom product design in the wearable industry. Energous is continuing its trend of launching a developer kit after having released the WattUp Hearables Developer Kit with Near-Field Wireless Charging and support for the SKIIN Smart Underwears. According to the Energous, the goal of the smart glasses developer kit is: Designed to […]
Nordic Semi nRF52832 Powered PineTime Dev Kit is Now Available for $24.99
PineTime was announced as a $25 smartwatch & companion for PinePhone Linux smartphone which itself sells for $150.

Galerdo AI Swimming Tracker Gives Audio Feedback, Plays Music – No Ear Buds Needed (Crowdfunding)
Galerdo Beker Pro Galerdo is a simple to use, swimmers attendant, that holds tight to the head and collects data. It offers interactive audio, AI advice underwater and even plays music through bone-conduction. We previously reported on fitness and swimming tracker Makibes F69 IP68 Smartwatch but it lacked audio support. Feature Awards for Galerdo Galerdo won the CES 2020 Innovation Award for Swim Tracker, AI Voice Assistant and Handset Free features. Previous and Present Devices Galerdo Inc has a previous bone-conduction audio device that offered music underwater to swimmers, without the need for a headband or earbuds. The latest device simply called Galerdo adds AI data collection and spoken advice as the user is swimming, in real-time. Quick Run Down on Bone-Conduction The AI technology that is used in the Galerdo is further enhanced by the bone-conduction transfer of sound and is a technology industry that is growing rapidly. It […]
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 […]
