$69 Linux Powered Arduino Yún Board is Designed for the Cloud

Massimo Banzi announced the Arduino Yún, the first of a family of Wi-Fi products combining Arduino with Linux, at the Maker Faire Bay Area. The company used the name Yún (云), meaning “cloud” in Chinese, as the purpose of this board to allow connection to web services directly from Arduino. Arduino Yun Specifications: MCU – Atmel ATMega32u4 @ 16 MHz (same as the one used in Leonardo board) with 2.5KB SRAM and 32KB flash SoC – Atheros AR9331 MIPS-based Wi-Fi SoC running Linino, Arduino’s own Linux distribution based on OpenWRT. It’s the same chipset as in TP-Link WR703N router. Storage – microSD card slot USB – micro USB connector + full USB host port Connectivity – Ethernet + Wi-Fi 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs) Arduino Yún ATMega32u4 can be programmed as a standard Arduino board by plugging it […]

N70-A and N70-B AllWinner A20 and A31 Based Android Netbooks with 13.3″ Display

Last year, H6 Android Netbook featured AllWinner A10 Cortex A8 processor, 1GB RAM, 4GB Flash, and came with a 10.1″ display with 1024×600 resolution, and people who tried did not seem very satisfied with their purchase. This year however, we should get more better hardware thanks to devices like N70-A and N70-B, respectively powered by AllWinner A20 with 1GB RAM, and AllWinner A31 with 2GB RAM, that both come with a 13.3″ display (1280×800). There’s also N101-A model powered by AllWinner A20, but it comes with a 10.1″ display with 1024×600 resolution. All models are available with 8, 16 or 32GB flash, feature Wi-Fi 802.11n and Ethernet connectivity, a 0.3MP front camera, an SD card reader, 2 USB ports, 1 HDMI output, as well as mic IN and headphone jacks. For some reasons, AllWinner A20 models runs Android 4.2.2, but AllWinner A31 still runs Android 4.1.2. You should be able […]

How to Play Games in Android mini PCs / STBs With a PS3 Bluetooth Controller

Android mini PCs ( HDMI TV dongles) are great to make your TV smart, and you may expect to be able to play Android games on your TV easily. The reality is that the keyboard and mouse, or remote controls used with those devices, are not suitable for games, and most games do not play at all. Of course, OUYA and GameStick projects will take care of this, as well as the recently available Project SHIELD ($349) , but if you already have one of those mini PCs, you may not want to spend the money for another device. Luckily there’s a solution, and with some efforts, you can play many games, but not all, with a PS3 Bluetooth controller connected to your Android mini PC or Set-Top Box. I decided to give it a try by buying “GOIGAME Rechargeable Bluetooth Wireless DoubleShock III Controller for PS3” for $16.60, which […]

Raspberry Pi Camera Module Is Now Available, How-to Use It

About one year after showing the first image from the camera module prototype, the Raspberry Pi Foundation announced the Camera board is now available for purchase on RS Component or Element14. Navigating either of these sites is a nightmare, but, if you’re lucky, you should eventually find the camera board for around $25 before taxes and shipping. “Raspicam” features the following hardware specifications: Omnivision 5647 sensor in a fixed-focus module 5MPixel sensor Still picture resolution: 2592 x 1944 Max video resolution: 1080p Max frame rate: 30fps Size: 20 x 25 x 10mm Connection by flat ribbon cable to 15-pin MIPI Camera Serial Interface (CSI) connector S5 on Raspberry Pi computer board The first thing you’ll have to do with the camera is to connect it to the CSI connector on your Raspberry Pi, just behind the Ethernet connector on model B. James explains it very clearly in the video below. […]

Intel Takes on ARM with Silvermont Microarchitecture for Low Power SoCs

Intel has launched Silvermont, a new microarchitecture for low power SoC targeting smartphones, tablets, and servers in data centers. Silvermont SoC will be manufactured using 22nm Tri-Gate SoC process, and the company claims 3x times more peak performance than current generation Atom processors, or 5 times less power consumption at the same performance level. Silvermont will be used in Bay Trail, Avoton, and Merrifield processors: Intel’s quad-core “Bay Trail” SoC is scheduled for Q4 2013 tablets, and variants of the “Bay Trail” platform will also be used in market segments including entry laptop and desktop computers. Intel’s “Merrifield” is scheduled to ship to customers by the end of this year, and actual smartphones will show up in 2014. Intel’s “Avoton” will be used in low power microservers, and provide full server product capability that customers require including 64-bit, integrated fabric, error code correction, Intel virtualization technologies and software compatibility. Intel […]

DroneShield – Raspberry Pi Powered Drone Detector

In case you are wary of having drones, such as RC helicopters, quadrotors…, flying around your house and invading your privacy, DroneShield can help you detect consumers’ drones by using a Raspberry Pi, a microphone and FFTW library, a C library for computing the discrete Fourier transform. The device will capture the audio with the microphone, analyze the noise spectrum of the drone flying around, and search for an entry in a signature database, and if a match is found the device will then send an email or SMS to inform you of the “invader”. There are complex challenges to overcome, or limitations, with this method, as any background noise will affect the detection, and drone emitting little noise or flying at high altitude won’t be detected. Spectrum analyses should however help avoid false positives such as a loanmowers and leafblowers as those emit a different kind of noise.They also […]

Picuntu Home://io Edition Brings GPU Acceleration to RK3066 based Mini PCs

Earlier this year, Picuntu (RC2), an Ubuntu-based distribution, was released for RK3066 powered HDMI dongles such as MK808, UG802, etc… More work has been going on since them, and Justin Gross (JustinTime4Tea) announced the release of Picuntu Home://io edition on SlateDroid. This distribution is based on Pictuntu RC3, supports GPU hardware acceleration, and lots of packages including Quake 3. GPU acceleration has been available since February thanks to olegk0, but I think it may be the first time it’s packaged into an installation image. Justin added a lot of goodies in this image including: Gaming – PCSX_rearmed Playstation Emulator and ioquake3 (with free demo files, replace with your own original Quake3 CD files) both supporting PS3 controller. Other games include GLTron, Solitaire, B.A.L.L.Z and a few more. Web Browsers – Midori, Firefox, and Chromium with support for Flash Graphics Tools – GIMP, Scribus, Inkscape, ImageMagick, etc… Email & Messaging Clients […]
