HEIF Image Container Format Leverages H.265/HEVC to Store Photos and Image Sequences

A few years ago, Google introduced WebP image format leveraging VP8 video codec, and the Moving Picture Experts Group (MPEG) has decided to do something similar but instead of using VP8, they went with their own H.265/HEVC video codec for HEIF image container format. HEIF stands for High Efficiency Image File, and is defined by ISO/IEC 23008-12 (MPEG-H Part 12). The storage of the data is based on ISO Base Media File Format (ISOBMFF), and HEIF appears to be especially useful to replace animated GIFs file with better quality and much lower sizes, as well as burst photos. HEIF also appears to compress a little better than JPEG photo with similar quality, but HEIF appears to fallback to JPEG codec sometimes, so it may be improvement in the way metadata is handled? The comparison table show the different features between HEIF and other well-known image format (JEG, WebP, GIF, etc…). […]

IkaScope WiFi Oscilloscope Probe Works with Windows, Linux, Mac OS X, Android and iOS

Last year, I wrote about Aeroscope, a portable Bluetooth oscilloscope that looks somewhat like a Stabilo Boss highlighter pen, and sends measurements over the air directly to your Android and iOS tablet or smartphone. It was introduced through a crowdfunding campaign which eventually failed, but Aeroscope can now be purchased for $199 on Amazon US or their own website. If you’d prefer WiFi over Bluetooth, and would like something that also works on Windows, Linux, and/or Mac OS X, IKALOGIC has just launched IkaScope WiFi oscilloscope probe compatible with all popular mobile and desktop operating systems. IkaScope WS200 specifications: Analog Bandwidth – 30 MHz @ -3dB Sample Rate – 200 MSps Connectivity – 802.11 b/g/n/e/i WiFi @ 2.4 GHz configurable as access point or station Input Range – +/-40 V range CAT1 Offset Range – +/- 20V to +/- 40V offset Input Impedance – 10MΩ || 14pF Input Contact – […]

Azul Systems’ Zulu Embedded is a Build of OpenJDK for ARM, MIPS, PowerPC, and x86 Compliant with Java SE standard

Yesterday as I wrote about the Embedded Systems Conference 2017 schedule I came across a potentially interesting talk entitled “Building A Brain With Raspberry Pi and Zulu Embedded JVM” by Azul Systems that will explain how to build a brain emulator using a cluster of Raspberry Pi boards. I wanted to find more about it, but I have not been able to find any details about the project/demo at this stage. However, I could still learn a bit more about Zulu Embedded, which is said to be an open source Java Virtual Machine based on OpenJDK, compliant with Java SE standard, working on 32-bit & 64-bit ARM & x86, MIPS, and PowerPC, as well as multiple operating systems. Some of the key features of Zulu Embedded include: Java Support – Java 6, 7, 8, and 9 when available Java Configurations – Headless, headful, or compact Java Compact Profiles Hardware – […]

BLCR MX3 is a $12 Backlit Air Mouse with QWERTY Keyboard

There’s an embarrassment of choices when it comes to air mice, but so far apart from models like Rii Mini i28 which looks more like a keyboard than a remote control, I had not seen air mice with backlit keys. But this morning BLCR MX3 showed up in DX new arrivals feed for $17.27 shipped, but you could also find it for about $12 on Aliexpress without BLCR “trademark”. [Update: Also on Amazon US for ~$16]. BLCR MX3 air mouse specifications: Connectivity – 2.4 GHz RF up to 10 meters Sensor – 6-axis sensor with gyroscope and g-sensor Remote side with IR learning function + backlit keys Air Mouse mode QWERTY keyboard with backlit keys Power Supply – 2x AAA batteries (not included) Dimensions – 17.2 x 5.2 x 1.9 cm Weight – 98 grams Material – Plastic + silicone The device ships with a USB dongle and user’s manual, […]

EyeTV NetStream Streams Free-to-Air Digital TV to Any Devices at Home

A few months ago, I wrote about TBS AMD Moi Pro streaming server supporting up to 16 tuners and mostly targeting businesses, but I’ve also found out there are some consumers solutions such as Elgato EyeTV NetStream 4Sat that includes four antenna inputs for your satellite dish (DVB-S2/S), and the ability to stream live TV to any devices, using hardware video transcoding if need be, for example to Android or iOS smartphones. Versions with DVB-T2 and ATSC will soon be available. EyeTV NetStream 4Sat specifications: Tuners 4x satellite inputs: F connector for RG-6/U coaxial satellite cable DVB-S2 / DVB-S Digital Universal LNB: Single, Twin/Dual, Quad or Quattro Unicable Integrated multiswitch DiSEqC 1.0 Connectivity – Gigabit Ethernet USB – 2x USB 2.0 host ports Misc – Reset button, power switch Power Supply – DC 12V 3A Dimensions – 25 x 12.6 x 4.1 cm (suitable for wall-mounting) Weight – 806 grams […]

Razberry Board and UZB Dongle Add Z-Wave (Plus) to Raspberry Pi Boards

Z-Wave is one of the low power wireless communication protocols used for automation, and supported, for example, by gateways such as Samsung SmartThings Hub or Vera3. Z-Wave Plus is a certification program used to identify Z-wave 5th Generation hardware platform, allowing a greater range up to 45 meters, 50% improvement in battery life, 250% more bandwidth, and providing a standardized method for Over the Air firmware updates (OTA), among other things. Zwave.me, a startup registered in Switzerland, is specializing in Z-Wave products and solutions, and among their other products they’ve also designed Z-Wave hardware to turn the Raspberry Pi board and other compatible hardware into a Z-Wave gateway. RazBerry module will fit into the 26 or 40-pin header found on Raspberry Pi boards, and comes with the following specifications: Sigma Designs ZM5202 Z-Wave transceiver module Frequencies – Storage – 32KB SPI flash for network data CPU/MCU Interface – UART (Tx/Rx) […]

MeLE F10 BT is a $20 Bluetooth Air Mouse and Keyboard

MeLE is mostly known as a manufacturer of Android TV boxes and air mice, and I use MeLE F10 Deluxe air mouse in all my Android mini PCs review, as even though it’s not perfect it does the job much better than an IR remote control, and is more convenient to use than a USB keyboard. The two MeLE air mouse I’ve purchased come with a 2.4GHz RF dongle that needs to be connected to a USB port of the device you want to control, but now the company is now about to launch a Bluetooth model with MeLE F10 BT. MeLE F10 BT (RF01BL) specifications: Connectivity – Bluetooth 4.0 (CSR1011) IR support – Yes, including IR learning function. Buttons Life – About 100,000 presses Sensors – G-sensor, Gyroscope Keyboard – QWERTY keyboard Battery – 2x AAA batteries (>30 days in standby mode) Dimensions – 169x48x19 mm Beside Bluetooth connectivity, […]

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. Hardware module undisclosed (Bean has an LBM313 Module with Texas Instruments CC2540) Up to 400 […]
