Motion Controlled Bluetooth Ring Mouse Sells for $50

Some companies sells Ring Mice such as Genius Ring Mouse 2, which is an RF ring you place on your index finger and control with your thumb more or less like a trackball, but there are also new generation rings using motion control. One of the product is the latter category is Fin Bluetooth Ring which allows you to control your computer, phone ot car radio by simply touching various parts of your fingers, however it’s been funded via an Indiegogo campaign, and based on their latest update they have not shipped rewards to backers yet. But I’ve recently been informed about a “Smart 3D Bluetooth Ring” selling for around $50 on Ebay using motion control and some buttons to control computers and laptops. Specifications and features for the ring include: Connectivity – Bluetooth 4.0 LE Technology – “Human motion sensor” Working Distance – Within 10 meters Button – 3 […]

LightBlue Bean+ Bluetooth LE Board is Programmed Wirelessly, Lasts One Year on a Charge (Crowdfunding)

Punch Through launched a crowdfunding campaign back in 2013 for LightBlue Cortado an innovative Arduino compatible BLE board that can only be programmed wirelessly over Bluetooth Smart. The board has since then been renamed to LightBlue Bean, and the company allegedly delivered rewards to backers on time, a rarity in the crowdfunding world. LightBlue Bean+, the second version of the board, is larger with solderless headers, supports more Bluetooth LE capabilities such as MIDI, and includes a battery. The project launched on Kickstarter yesterday, and already raised over $40,000, surpassing the $30,000 funding target set by the team. LightBlue Bean+ board specifications: MCU – Info N/A (Bean has an Atmel ATmega328P @ 8MHz with 32KB Flash, 1KB EEPROM, 2KB SRAM) Bluetooth Bluetooth LE with support for 5 new capabilities: beacon, MIDI, HID, ANCS and observer role.

Espressif is Working on a New Wi-Fi and Bluetooth LE Chip with Hardware SSL Support

Espressif came to fame thanks to its low cost ESP8266 WiFi chip which was originally designed for connected lightbulbs, but soon got used in a variety of applications, and ESP8266 modules must now be the most popular solutions to add WiFi to IoT projects, as long as they are not battery powered. The company has recently announced they were working on a new chip, whose name as yet to be decided, that will support both Wi-Fi and Bluetooth Low Energy. Details are sparse, but we do know the chip will come with 500KB RAM, support hardware SSL and possibly ECDH, deliver 500 DMIPS of performance, and consume 5 uA in deep sleep mode. The company asked for beta testers via their twitter account around 2 weeks ago, so I guess it’s a bit too late to apply. John Lee, working for Espressif, also said the new part should become available […]
