Virtualette V1, A Tiny Powerful Microcomputer

Designed by SRKH Designs, Virtualette V1 is a small dual stack microcomputer that can run Android and Linux operating systems, for network-wide IoT and mobile edge computing solutions and electronics DIY projects.

Virtualette V1 is designed based on the dual-core Cortex-A7 Allwinner A20 SoC, with 1GB DDR3L base memory, 8GB onboard NAND flash, and a 32GB microSD card. It also includes a real time clock, onboard battery and wakeup function, and 80 IO pins.

The microcomputer is consist of dual connected PCBs with 7.6cm x 3.7cm x 1.8cm size including mounting feet. It has an Ethernet jack, a USB port to connect mouse or keyboard, microSD card slot, SATA port, and mini USB ports.

Virtualette V1 is a low energy device with a typical 2.4W of energy draw with three power options; 9-48V PoE (Powered over Ethernet), 5V USB OTG, and a lithium battery.

You can run any of linux-based operating system on the V1, in addition to the optimized linux distribution that will be shipped with it. Users can change the OS by swapping over the micro SD card and they have the option of booting from an external microSD card or from the onboard NAND 8GB flash.

Additional storage can be added by inserting a USB2 drive or external hard drive (SATA compatible). V1 can be optionally booted by USB or a dedicated SPI ROM port.

Examples of V1’s potential capabilities are:

  • As an individual desktop device or controller for a drone or robot.
  • As a liquid-cooled computer inside a 40mm PVC pipe.
  • As M2M nodes in a distributed intelligent security system.
  • Deployed as a peer-to-peer, machine-to-machine network in applications such as display information systems in airports or train stations.

With the launch of their Kickstarter campaign, SRKH Designs aims to raise funding of US$22.5k, offering backers Virtualette V1 devices from the first production run as their reward.

Post campaign, a roadmap of hardware products for the Virtualette range is planned. This includes future quad-core and octa-core versions, an add-on FPGA-based development board, a desktop platform, popular video adaptor interfaces and an ‘All in One’ peripheral board designed to embed V1 inside a slimline display case.

Turn Your Raspberry Pi Into A Wi-Fi Drone Disabler

Note: The information presented here is for educational purposes. This tutorial is designed to help users understand the security implications of using unprotected wireless communications by exploring its use in a popular drone model: the Parrot AR.Drone 2.0. It’s illegal to access computer systems that you don’t own or to damage other people’s property, the techniques should only be performed on devices that you own or have permission to operate on.

Using a Raspberry Pi with a touchscreen, and running a couple of simple Bash scripts, Brent Chapman built a device that will drop Wi-Fi controlled drones right out of the sky with just a tap of your finger.

wifijammer

The device concept is finding the unsecured Wi-Fi access point used by the pilot smartphone or tablet to control the drone, then log on to the drone’s default gateway address, and shuts down the system from the inside without the pilot knowing.

This will only work on some models of drones which use Wi-Fi as the interface between the controller and the drone, such as Parrot’s Bebop and AR.Drone 2.0, that are entirely controlled via Wi-Fi.

The AR.Drone 2.0 is an ideal platform for experimentation and learning thanks to its many impressive features and sensors plus its low cost. It creates an access point named “ardrone2_” followed by a random number, that the user can connect to via a smartphone. This access point is open by default with no authentication or encryption. Once a user connects the device to the access point, he or she can launch the app to begin control of the drone.

At first, you have to connect the Raspberry Pi with a touchscreen, this guide by adafruit might be helpful. When they are ready, the next step is preparing couple of bash scripts. The first is named “join_network.sh”, and it used to make the Pi automatically join the AR.Drone 2.0 access point.

The second script is named “poweroff.sh”,it will initiate a telnet connection to the drone, then send the command of poweroff, which tells the drone to shut everything down.

The last step is building a “Cantenna”, a DIY directional antenna made of a can to boost the wireless signal. You just need to drill a hole on an empty can to hold a N connector then connect it to Wi-Fi card.

Keep in mind, you should only try this tool on your own personal drones safely and at your own risk. You can find the complete guide at this link at makezine.

Crowdfunding closing on $5 Linux + Wifi tiny IoT compute module

6c15c56111eae091b957a1640ea8e56e_original

World’s smallest Linux server, with Wi-Fi built-in. Omega 2 is a Linux compute module designed specifically for building connected hardware applications. It combines, say its designers Onion, “the tiny form factor and power-efficiency of the Arduino, with the power and flexibilities of the Raspberry Pi.” By Graham Prophet @ edn-europe.com

Omega 2 development is the subject of a Kickstarter campaign, that closes on August 23 rd 2016 ( here). The projects starts with the base module, which is an SoC-based board with built-in WiFi, and extends through levels of added connectivity, and peripherals – for example, there is a ‘dock’ card that provides compatibility with Arduino-format hardware. Part of Onion’s offering is a cloud service, so that an Omega 2-based project can be fully cloud-connected and -enabled.

Exploring the Transcend Wifi-SD card

Transcend-WifiSD-16Go-512px_805434CD

James O’Neill explores a Transcend SD that he believes it’s the smaller Linux server. It’s actually a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package.

The way these cards works is different from the better known Eye-FI card. They are SERVERS : they don’t upload pictures to a service by themselves, instead they expect a client to come to them, discover the files they want and download them. The way we’re expected to do this is using HTTP , either from a web browser or from an App on a mobile device which acts as wrapper for the same HTTP requests.

Setting Up Python web server for Raspberry Pi

PiHttpServer-2

Sankar Cheppali will show us how to setup a python based web server to serve simple html pages to the clients using Raspberry Pi.

Serving web pages from embedded devices is not easy task as embedded devices have limitations in processing power , memory available etc. But with Raspberry Pi this task becomes very easy. We have lot of packages, programming platforms and libraries to chose from because pi is from Linux family.

UP – Intel x5-Z8300 board in a Raspberry Pi2 form factor

up_board

UP, the credit card computer board for makers powered by Intel Quad Core Atom X5-8300 1.84GHz, running Linux, Windows 10, and Android

We haven’t seen anything like that on the market. We saw plenty of cost effective boards, often powered by RISC technology, and industrial solutions with a wide range of standard form factors, performance and technology but with high prices and poor or absent community support. We tried to merge the best of the two worlds, makers and industrial market. Maybe we were asking for too much. Or maybe not. We put the best x86 low power consumption and high performance technology available today in the market into a credit card size board and created a community to support it.
The answer is UP.

UP is a credit card size board which merges the benefits of Raspberry Pi2, the standard “de facto” of makers with the high performance and low power consumption of latest tablet technology : the Intel Cherry Trail Atom Quad Core x5-Z8300 64 bits up to 1.84GHz ( http://ark.intel.com/products/87383/Intel-Atom-x5-Z8300-Processor-2M-Cache-up-to-1_84-GHz ). Thanks to the 14nm technology, the CPU is rated at only 2W SDP.

Open source pocket USB oscilloscope; 30 MHz, multi-platform

fully_equipped-82865c647ca6155d5ba3782f757d0c6f

by Graham Prophet @ edn-europe.com:

Running on Apple iPad, Android, Microsoft Windows and Linux, LabNation’s (Antwerp, Belgium) open source USB oscilloscope, SmartScope, is the result of a Kickstarter campaign commenced in 2014 – the project raised 645% of the funding goal within 30 days.

Believed to be the first test equipment designed to run on multiple operating systems and platforms such as smartphones, tablets and PCs, the lightweight SmartScope is powered directly from the host’s USB interface suiting it for many test and measurement applications far from the workbench.
