Flic Hub Controls WiFi, Bluetooth, and IR Devices with Bluetooth LE Buttons (Crowdfunding)

This week-end, I wrote about 1btn open source WiFi button that can allow you directly control WiFi appliances, and/or set scenes without the need for a smartphone. We also discussed limitations of WiFi due to high power consumption, security issues and the one-way aspect of RF communication, and that Bluetooth 5 may be a better option for range and battery life if possible. Flic Hub is another way to approach the issue, as it combines Bluetooth LE buttons with a gateway supporting WiFi, Bluetooth, and infrared. Flic Hub gateway specifications: Connectivity – Bluetooth Classic, Bluetooth LE, WiFi, Ethernet, IR via optional add-on accessory. Audio – 3.5mm audio out/mic in Power Supply – 5V via micro USB Power Consumption – 1.5W typ. Security – SPARKE2+ Bluetooth encryption Dimensions – 85 x 50 x 15 mm Weight – 99 grams Users can configure workflows by setting up Flic with IFTTT, Zapier, Microsoft […]

Opus 1.2 Allows for High Quality Stereo Music @ 32 Kbps, Speech @ 12 Kbps

The Xiph.Org Foundation has recently announced the release of Opus 1.2 open-source audio codec with ever lower high-quality audio bitrate for music (32 Kbps) and speech (12 Kbps), faster encoding and decoding, and other tweaks to the standard and library. If you’ve never heard about Opus or need to refresh your memory, you may want to read my previous article about Opus Open Source Audio Codec. The developers improve music quality by “adjusting the bit allocation trim, improving tonality analysis with better frequency resolution, and improving quality on signals with a few very powerful tones”. You can compare Opus 1.0, 1.1 and 1.2, and MP3 at different bitrates on Xiph website. You’ll need a browser that supports Opus and MP3 in HTML5 for this to work (Chrome, Firefox, and Opera do), or you may hear another sample as if Opus support is missing the file will be played as a […]

Jolla Tablet Take 2 – Youyouta Tablet Runs Linux Based Sailfish OS 2.1 Operating System (Crowdfunding)

Jolla Tablet running Linux based Sailfish OS was launched in 2014 via Indiegogo, and the campaign was initially very successful having raised over 2.5 million dollars, but eventually it became a disaster as the company had some financial issues, and the tablet was canceled with on a few backers having received their tablet. The company eventually organized a refund program, so it did not end up being as bad as it first seemed. But there’s now a “new” SailFish OS tablet – Youyouta tablet – that has been launched on Indiegogo last month. Jolla is not handling the manufacturing and campaign, and instead it’s done by a third party who is paying license fees to Jolla for Sailfish OS. They re-used most parts of the hardware design from original Jolla tablet plus a few modifications like option for higher storage capacity: SoC – Intel Atom Z3735F quad core “Bay Trail” […]

1btn is a Battery Powered Open Source ESP8266 WiFi Button

If you have some WiFi power switch like Sonoff TH16 at home, you’d normally control them using a mobile app or a web interface. This is all good, but getting your phone, unlocking it, and launching the app to turn on or off an appliance is not the most efficient way to operate, and in some cases, some people in the household may not know how to use a smartphone. Physical WiFi buttons are the solution, but there aren’t so many for sale. We’ve seen previously it was possible to hack an Amazon Dash, but it’s not really that flexible, and 1btn could potentially be a better option, as it’s open source and based on Espressif ESP8266 WiSoC. 1btn specifications: WiFi Module – ESP-12F based on Espressif ESP8266 MCU – Microchip Atmel ATmegaxx8 AVR MCU Connectivity – 802.11 b/g/b WiFi up to ~50 meter range USB – 1x USB port […]

HT-01 “Helping Hand” Soldering Stand Comes with 6 Arms, a USB powered Fan

I have a “helping hand” in my office with two flexible arms and alligator clamps, and a magnifier that I use sometimes to solder or unsolder components more easily. The metallic arm are not always easy to put in the right position, and the base is not always heavy enough, but it does the job most of the time. But I’ve just come across with a helping hand station with 6 flexible gooseneck arms that may allow for more positions and easier setup, as well as hold a USB powered fan to such out fumes or blow them away, and/or a lamp. HT-01 soldering station features: Aluminum alloy base – 140 x 100 x 12mm (purple or black) 6x universal joint pipe of 300mm length with alligator clip 1 5V USB output regulator plate with two USB ports up to 5V/3A to connect fans 1x 5V USB Fan 1x Soldering […]
