Windows 10 IoT Preview for Raspberry Pi 2 and MinnowBoard Max

When Raspberry Pi 2 Model B was released, we were promised a Windows 10 image for the board, and today, Microsoft released “Windows 10 IoT Core Insider Preview” for both the Broadcom BCM2836 based Raspberry Pi 2 and Intel Atom E3800 series based Minnowboard MAX boards. To get started with either board, simply go to Windows IoT – Getting Started page. I’ll quickly go through the instructions for Raspberry Pi 2. Beside the board, you’ll also need a PC running Windows 10 Insider preview (Virtual machine not supported), a 5V power supply, a HDMI cable (optional but recommended), an Ethernet cable, and a 8GB micro SD card, class 10 or better. The you’ll need to configure a connect account, where I had to accept two EULA including “Windows 10 IoT Core Insider Preview EULA”, and once this is done the area of the page for EULA should just be blank, […]

$10 Digistump Oak ESP8266EX Board is Arduino Compatible, Connects to the Cloud, and More (Crowdfunding)

A few years ago, I wondered why adding Wi-Fi to Arduino had to be rather expensive ($40+), and why there weren’t any low cost and small form factor Wi-Fi boards for embedded applications. But we’re now in 2015, embedded is “dead” giving rise to IoT, and I’m left wondering how it’s possible to make IoT Wi-Fi modules that cheap, and whether people will ever stop churning out cheap Wi-Fi boards, as I’m flooded with such news weekly… So when I saw yet another ESP8266 board on Kickstarter I was about to dismiss it, but since it was made by Digistump, that has an active community with their other products like DigiSpark Pro or DigiX, I decided to have a closer look. Digistump Oak hardware specifications: MCU – Espressif ESP8266EX 32-bit microprocessor @ 80MHz (overclockable up to 160MHz)  with 1MB ROM (~300KB available for user code), 64KB RAM, 512 bytes EEPROM […]

Tizen OS Ported to the Raspberry Pi 2

Tizen may not be overly used in devices, but there has been ports of the operating system on various ARM platform, mostly development boards, powered by Allwinner, Rockchip, Freescale SoCs, and more… Seeing the popularity of Raspberry Pi 2 Model B, Samsung Open Source Group decided to port Tizen to the latest version of the hobbyist board. The full instructions are rather long, and provided in the link above, but the main steps – using a Linux based computer – can be summarized as follows: Create a local copy of tizen-distro Add Raspberry Pi 2 BSP Meta repository Initialize the environment and modify some config files Start the build with Yocto: bitbake rpi-hwup-image. This should make a minimal headless? image Create an SD card image with tmp-glibc/deploy/images/raspberrypi2/rpi-hwup-image-raspberrypi2.rpi-sdimg using dd, an optional resize the parition with gparted or fdisk/resize2fs. Insert the SD card in to your Raspberry Pi 2, and have […]

ARDHAT adds Arduino Shield Compatibility, an ISM Band Radio to Raspberry Pi and ODROID-C1 Boards (Crowdfunding)

NinjaBlocks created Pi Crust add-ons board adding a 433MHz radio and Arduino compatibility to the Raspberry Pi Model A & B a few years ago, but the product has since been removed from their store. But a startup called ubIQio has now created a similar product compatible with Raspberry Pi Model A+, B+ and B2, as well as ODROID-C1 which also comes with a 40-pin R-Pi header. The ARDHAT board is a HAT compatible add-on board with an Atmel MCU, Arduino headers, as well as an optional long range mesh ISM radio (433, 868 and 915 MHz) and various sensors. There are four versions of the board: Basic Ardhat, Ardhat-I, and Ardhat-W and Ultra, which share the following specifications: MCU – Atmel MCU @ 16MHz Headers and I/Os Arduino compatible header accepting 5V Arduino shields 12 ch PWM O/P, 6 ch analog I/P Real-time Clock Programmable Power/Navigation combo switch Programmable […]

Kodi 14.2 Final and Kodi 15 Alpha 2 Released

Kodi developers have recently announced two release for Kodi: the stable version of Kodi 14.2 Helix, which should be the last Kodi 14 release, and Kodi 15 Alpha 2 Isengard with some interesting new features. Since Kodi 14.2 is a minor release, no new features have been added, but they fixed several bugs: Application stopped responding on Windows Gap-less playback on MP3 Playback of rtmp protocol Scanning of newly added episodes Fix multipath source scanning Loading external subtitles in some cases packaging of PIL module on Android. This fixes some script error when using weather add-on Fix video playback on all platform after refresh rate change Various bugs that were present in PVR add-ons. Save weather location Fix filtering of foreign add-ons ftps handling Use LastWrite instead of ChangeTime for file system on Windows As usual, you can download the release via Kodi download page for Windows, Linux. Mac OS […]

PiJuice Battery HAT Module for the Raspberry Pi Boards Comes with an Optional Solar Panel (Crowdfunding)

The Raspberry Pi is a low power board that can be powered a few hours or a few days with batteries, and the easiest solution is probably to use a USB power bank connected to the micro USB port of the board, but the solution is not really integrated. That’s where PiJuice comes into play. It’s a HAT compatible module that connects nicely to the latest Raspberry Pi boards with 40-pin header (A+, B+ and B2), and include a 1,400 mAh battery that can be used as UPS (Uninterrupted Power Supply), an RTC, and more. Key features of PiJuice HAT: 1400 mAh  Lipo battery, good enough to last up to 24 hrs in constant use. 5,000 mAh batteries are also said to be supported. Full UPS (Uninterrupted Power Supply) solution Integrated RTC (Real Time Clock) On board intelligent on/off switch Low power deep-sleep state with wake on interrupt/calendar event On […]

Experimental Android 5.x Lollipop Port for Raspberry Pi 2?

When Raspberry Pi 2 was announced, I was quite hopeful Android would be ported to the board since it now had the processing power and memory requirements to run Android. But members of the Raspberry Pi foundation put a damper on this expectation directly in their Android forums by closing some Android related threads, and stating the mobile operating system does not bring anything to the educational goal of the Raspberry Pi. But yesterday, I’ve been informed that there was an experimental Android 5.1 port for ODROID-C1 and another Android 5.x port for Raspberry Pi 2. One of the key challenges to port Android to Broadcom BCM2836 is allegedly the large number of changes required for VideoCore 4 GPU’s buffer management, which was done by Broadcom internally for BCM2835, but never ported to the Raspberry Pi. So it does not quite seem an easy task. The README on github describes […]

Calaos is an Open Source Home Automation Suite for Raspberry Pi, Allwinner A10/A20 and x86 Platforms

Calaos is a Linux based home automation software released under GPLv3 license that works on Raspberry Pi, some Allwinner platforms like Cubiebaord 1/2, Mele A1000(G)/A2000, as well as x86 / amd64 hardware platforms that allows you control switches & lights in the rooms of your home or office, control your music, and manage security cameras.. The developers have recently released Calaos v2.0, the first stable release, so it’s a good time to have a look.
