Olimex Announces 30 Euros A10-OLinuXino-LIME Development Board for December

The Raspberry Pi, Beaglebone Black and Cubieboard are probably the best selling ARM Linux boards in the sub $50 category, but they’ll soon be joined by Olimex A10-OLinuXino-LIME powered by AllWinner A10 ARM Cortex A8 SoC with 512MB RAM that will sell for 30 Euros (About $40) when it becomes available in December. Another version of the board based on AllWinner A20 dual core Cortex A7 SoC, called A20-OLinuXino-LIME will also be sold, adding Gigabit Ethernet, and scheduled for Q1 2014. Pricing has yet to be disclosed for the A20 version. A10-OLinuXino-LIME specifications: SoC – AllWinner A10 ARM Cortex-A8 @ 1GHz with Mali-400 GPU System Memory – 512MB DDR3 Storage – microSD card slot, SATA, and optional 4GB NAND Flash Video Output – HDMI 1080p USB – USB-OTG + 2x USB Hosts Connectivity – 10/100Mbit Ethernet Expansions – 200 GPIOs on 0.05″ connectors Misc – Lipo battery management and connector, […]

Ubuntu for Raspberry Pi May Be Available Soon (Sort of)

Since the Raspberry Pi was launched many people have asked, and still ask, if/when Ubuntu will be available for the Raspberry Pi. As Canonical decided to only provide support for ARMv7 and higher architecture, for optimal performance and user experience on recent hardware, and Raspberry Pi is powered by Broadcom BCM2835 processor based on ARMv6 architecture, this did not happen, and instead a version of Debian called Raspbian became popular, and is still the main OS used by most people. But a team of developers in the UK has recently decided to give it a try and launched a flexible Indiegogo campaign in order to purchase enough Raspberry Pi boards and required accessories (power supplies, SD cards, cables…) to setup a build farm for Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04. They plan to acquire at least 32 Raspberry Pi boards for their build farm. But don’t get too […]

Ninja Pi Crust Let You Connect Arduino Shields to the Raspberry Pi

There are quite a few projects using both the Raspberry Pi and an Arduino board and its shields together. These are working but the cabling may get messy. People have already found solutions to plug Arduino shields into the Raspberry Pi with products such as Cooking Hacks’ Raspberry Pi to Arduino shield connection bridge (40 Euros) or Open Electronics’ Raspberry Pi bridge (22.50 Euros). Those two boards are fine, but do not include an Atmel MCU, and use Raspberry Pi GPIOs directly, except for their ADC. Another solution is the Paperduino Pi, a DIY Arduino board that can be plugged on top of the Raspberry Pi, and compatible with Arduino shields. But if you want an Arduino board that can easily be stacked between the Raspberry Pi, and Raspberry shield, the upcoming Ninja Pi Crust by Ninjablocks may be an interesting option, especially if you plan to use the 433MHz […]

Frindo Open Source Robotics Platform for Arduino and Raspberry Pi Boards

Frindo is both a community and an open source robotics platform designed to work with Arduino, Raspberry Pi, and possibly other micro-controller boards. The platform is said to have been designed as an educational platform so that beginners can start with a simple robot, and build a more complex robot as their skills grow. There are currently three Frindo kits available from RobotBits.co.uk: Frindo chassis only kit for £64.95 (~$104) – Chassis plates, motors, wheels, wheel brackets, Arduino & Pi mounting kit & all hardware. Frindo Arduino kit for £110.95 (~$178) – Chassis only kit + Arduino, RobotShield, battery clip, power cable & USB cable Frindo Arduino kit plus sensors for £159.9 (~$257) – Arduino kit + 3x each: GP2Y0A21 analog distance sensors, bracket, cable & fixings The RobotShield is an Arduino shield optimized for mobile robotics applications with the following features: Dual bi-directional motor driver circuit (2 Amp Peak, […]

SparqEE CELLv1.0 Devkit Adds a SIM Card to Your Arduino, Raspberry Pi, or Other Hardware

There are several ways to add wireless connectivity to your sensors, relays, motors, or other devices. Bluetooth, Zigbee and Wi-Fi can all do a good job for short ranges, and the Weigthless standard will eventually provide ranges up to 10km with ultra low power on free spectrum, but it is not available right now, and a good way to achieve longer ranges is to use cellular networks. SparqEE has designed a development kit called CELLv1.0 to add GSM and 3G connectivity to the Internet of things, including (optional) shields for Arduino and Raspberry Pi boards. Here are some technical specifications for the kit: Cellular Networks – WCDMA/HSDPA 2100/1900/900MHz, GSM/GPRS/EDGE 850/900/1800/1900MHz, 384Kbps, DL3.6Mbps HSDPA via ZTE modem Protocols – Data (TCP/UDP), SMS ready Serial interface – Serial (UART, From Cellular Board is 1.8V, From Jumper board is any voltage (ex. 3.3V, 5V)) USB – (power, USART, and modem) Input Voltage – […]

HDMI to VGA Adapters Now Cost About $10

I remember when the Raspberry Pi first got out, many people wanted to connected it to a VGA display, and at the time, a cheap HDMI to VGA adapter would have cost $30, about the same price of the low-cost ARM11 board. Since then things have changed since it’s possible to find HDMI to VGA adapters for less than $10, and even less than $7 on Aliexpress. The one linked and pictured above has an HDMI male connector and a VGA female connector, and the following features listed in buyincoins: Support 1080p and 720p. Built-in chipset. No external power required, power supply from HDMI signal. Don’t support audio output. Can use for connecting devices with VGA port to HDTV. HDMI – standard type A port male. VGA – VGA video port, female. The title seems to imply it’s an HDMI to VGA adapter, but the description tells you it’s for […]

WigWag Simplifies Home Automation, Provides Raspberry Pi and Arduino Shields

WigWag is an home automation kit aiming at simplifying home automation, yet allowing developers to roll their own system via Arduino and Raspberry Pi Shields. Wigwag is currently composed of three devices: WigWag Sensor Block – Universal sensor device with 8 environmental sensors (light, detect motion, sound, temperature, humidity, movement…), 4 control features (relay, IR blaster…), and 2 expansion ports. It can be powered by 4x AA batteries (possibly for up to 1 year), or a USB power adapter. This device runs Contiki OS on Freescale MC1322 MCU (with built-in 6LoWPAN radio). WigWag Relay – Connects WigWag and third party devices to their cloud service, allowing interaction with Internet services, such as email, Dropbox and Twitter. It acts a bit like a central server managing all your WigWag Sensor Blocks or other connected devices such as Phillips Hue light bulbs or Belkin WeMo outlets in your house. IP networks (Wi-Fi & Ethernet) […]

DIY Stripboard/Veroboard Enclosure for Raspberry Pi (Part 2)

Following up my previous post entitled “DIY Modular Stripboard / Perfboard Casing for Raspberry Pi (Part 1)” where I explained how I created an modular enclosure made of perfboard, or the overall concept, I’ve now designed two “smart” sides for the enclosure: a 16-LED stripboard side, and a 5V relay stripboard side. Today, I’ll detail how I’ve done this, with details about electronics, soldering, assembly, the Linux distribution (built with Yocto), as well C programs, HTML page, and (CGI) shell scripts used to light up the 16 LEDs, and control a standard 220V lamp with a relay via my phone’s web browser. 16-LED Stripboard Top Schematics, Soldering, and Testing I had decided to design the top board of the enclosure with several LEDs, 3 LEDs on both side, and a Raspberry fruit (6 red LED) and 2 leaves (4 green LED) in the middle. Before getting started, I did some […]
