JBL Reflect Eternal are Self-Charging, Solar-Powered Headphones (Crowdfunding)

JBL REFLECT Eternal Self-Charging Headphones A simple solution to the constant problem of having to charge wireless earbuds is to make it so they never need a charge, at all. That means do not use an AC adapter or USB charger, and instead, use solar power. The JBL REFLECT Eternal headphones are solar-powered and never need charging. JBL an Iconic Brand The iconic audio company has been moving inexorably into the 21st century with Bluetooth enabled wireless speakers, headphones and other up-to-date tech-enabled audio equipment. How Solar is Used to Power the JBL REFLECT Eternal headphones The headphones can turn artificial and natural light into energy through the Exeger Powerfoyle process. The company states “more light, more playtime” which is true in its basic aspects. Self-Charging Issue The self-charging portion of the process of charging for the JBL REFLECT Eternal can be slow, and sometimes not power up the headphones […]

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 […]

Giveaway Week – Particle Mesh IoT Development Kit

In early 2018, Particle introduced three nRF52840 Bluetooth 5 boards, also supporting the company’s Particle Mesh technology, and selling for as low as $9. Later that year, the company send me what they call Particle Mesh IoT development kit with several of those boards to get started with their mesh networking solution. That’s what I’m offering as the 6th prize of this giveaway week. With this kit on hand, I wrote a Particle Mesh networking getting started guide showing how to configure the board in Particle.io dashboard, and easily push a new program to multiple Xenon Bluetooth 5 + Mesh boards using an Argon WiFi & Bluetooth 5 + Mesh as the gateway. I’ll give away the full kit shown in the top picture which includes: The Argon kit (ESP32 WiFi + Bluetooth + Mesh) A Grove and Particle Sensor Kit with various modules and a shield An Adafruit Featherwing […]
