RAK WisCam is a $20 Arduino Compatible WiFi Camera Linux Board Powered by Nuvoton N32905 ARM9 Processor

A couple of weeks ago I wrote about Rakwireless’ RAK CREATOR Pro development board based on Realtek Ameba RTL8711AM Wireless MCU, and part of their Wiskey family of development boards. Sub-family include WisNode for IoT boards, WisAP for OpenWrt boards, WisPLC for PLC hardware, and WisCam for WiFi video camera boards. The company has recently introduced Wiscam RAK5281 Arduino compatible Linux board powered by a Nuvoton ARM9 MCU, and supporting a camera module or an SD card + USB module. RAK WisCam specifications: SoC – Nuvoton N32905R3DN ARM926EJ processor @ 200 MHz with 8KB internal SRAM, 16KB IBR internal booting ROM, 16Mbit x16 DDR2 memory Storage – 128 MBit SPI flash, included sub-module adds micro SD card Connectivity – 802.11 b/g/n WiFi via Realtek RTL8189FTV module Camera via sub-module 648×488 pixel VGA CMOS Image Sensor (GC0308); 102° FOV Video – QVGA (320×240) 30FPS, VGA(640×480) 30FPS, MJPEG encoding Photo – JPEG, […]

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted. That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon. The company has recently announced their Track 100 family […]

$399 Intel Euclid Robotics Devkit Runs Ubuntu & ROS on Intel Atom x7-Z8700 Processor

We’ve seen many mini PC based on Intel Atom x5/x7 “Cherry Trail” processor in the last year, but Intel has also integrated their low power processor into hardware aimed at robotics, such as Intel RealSense development kit based on Atom x5 UP Board and RealSense R200 depth camera. The company has now launched its one-in-all Intel Euclid development kit combining Atom X7-Z8700 processor with a RealSense camera in a single enclosure. Intel Euclid specifications: SoC – Intel Atom x7-Z8700 Cherry Trail quad core processor @ up to 2.4GHz with Intel HD Graphics Gen 8 System Memory – 4GB LPDDR3-1600 Storage – 32GB eMMC 5.0 flash, Micro SD slot up to 128GB Video Output – micro HDMI port up to 4K @ 30 Hz Audio – 2x I2S interfaces, 1W mono speaker, 3x DMIC with noise cancellation Camera – Intel RealSense ZR300 camera RGB camera – 2MP up to 1080p@30fps, 16:9 […]

PragmatIC Manufactures Ultra Thin and Flexible Plastic Electronics Circuit, Plastic ARM Cortex M0 MCU Coming Soon

Electronics manufacturing now relies on silicon wafers, and it works great for many applications. However, some other applications require or benefit from a cheaper price, thinner circuits, and flexibility, and PragmatIC addresses all those three issues with technology to print electronics circuits on plastic sheets. The technology is said to costs less than 1/10th cost of silicon, with the circuit printed on 10 μm thick flexible plastic “wagers” with support for 10 layers. Circuit starts from basic gates up to ARM Cortex M0/M0+ chip as shown above. Simpler circuits are currently sold for as low as $0.01, but the area for Cortex M0 MCU is 1cm2, and a bit too big for commercial applications, so they plan on shrinking the process to make it commercial viable. ARM is an investor in the company, and PragmatIC is ramping production capacity with the ability to manufacture on billion plastic chips/circuits in 2018. […]

Using GPIOs on NanoPi NEO 2 Board with BakeBit Starter Kit

NanoPi NEO 2 is a tiny 64-bit ARM development board powered by Allwinner H5 processor. FriendlyELEC sent me a couple of NEO 2 samples together with their BakeBit Start Kit with a NanoHat and various modules via GPIOs, analog input or I2C. I’ve already tested both Armbian with Linux 4.11 and Ubuntu Core Qt with Linux 3.10, and ran a few benchmarks on NanoPi NEO 2. You would normally prefer to use the Armbian image with Linux mainline since it provided better performance, but at the time I was told GPIO support was not there. Configuring NanoPi NEO 2 board with BakeBit library So this week-end, when I decided to test GPIO support and BakeBit Starter Kit, I decided to follow this advice, especially nanopi-neo2-ubuntu-core-qte-sd4g-20170329.img.zip image is still the recommended one in the Wiki. So I went with that image. I’ll use Python examples from Bakebit library, but if you […]

ABC: Basic Connections is a Book Listing Common Circuit Diagrams for Arduino Boards (Crowdfunding)

PighiXXX is known for their very useful and pretty pinout diagrams, but they’ve now created a book called “ABC: Basic Connections” comprised of a collection of easy to read circuit diagrams that shows you how to connect various circuits to your Arduino compatible board. The book is in file folder format, so you can easily remove the sheets you need during your project. While you can normally find pretty much whatever circuits you need on the Internet, ABC book’s diagrams looks very neat, and since it comes with 100 A5 pages of circuit diagrams such as LEDs, decoders, shift registers, 7-segment displays, mux/demux, light bulbs, DC motors, solenoids, relays and so on, you may discover circuits you did not know you needed. Every page of the book also comes with a 0-1.es/xx short URL redirecting to an online tutorial for the circuit with information about the theory, component list, tips, […]

Sen5 Amlogic S905D TV Box Review – Part 2: Android Firmware, Kodi 17, and DVB-T2 & S2 App

Sen5 is one of the first Android TV boxes powered by Amlogic S905D processor, and comes with two tuners (DVB-C/T/T2 and DVB-T/T2) with two demodulators that should allow for recording on one tuner, while watching the other, or recording two channels at the same time. We’ve already check out the hardware in the first part of the review, and seen a glimpse of the neat user interface, so today I’ll report about my experience with the device. Sen5 Android Set-Top Box First Boot, Setup Wizard, & First Impressions The STB comes with two USB ports so I used one for the hard drive, a necessity if you plan to use the PVR function, and connected a USB hub to the other with RF dongles for an air mouse and a gamepad, as well as a USB keyboard to take screenshots. I also connected Ethernet and HDMI cables, as well as […]

Android Studio 3.0 Preview Release with Support for Kotlin Programming Language, Android O Preview Images

Most Android apps used to be programmed in Java with the Eclipse IDE, then Google introduced Android Studio in 2013 which has now replaced the latter, and with the release of Android Studio 3.0 Canary 1 preview, the company is now offering developers to program apps using Kotlin language instead of Java. Kotlin programming language is 100% compatible with Java language, and you can even mix Kotlin and Java in your code. Kotlin can make your code much more simple while declaring classes, and it has a few other improvements over Java. Android Studio also include a Java to Kotlin converter. The language has already been used by Expedia, Flipboard, Pinterest, Square, and others. Android Studio 3.0 also brings many other improvement, such as performance profiling tools for the CPU, memory, and networks showing your app performance in real-time, and faster Gradle builds for large sized app projects. Android Studio […]
