Intel’s Movidius Neural Compute Stick Supports Raspberry Pi 3 Board

Last month, Intel introduced Movidius Neural Computer Stick to accelerate applications such as object recognition, and do so offline, i.e. without the cloud, and at low power. While there was not that much information available at the time, the minimal requirements for the host machine were that it had to be a x86_64 computer running Ubuntu 16.04, and come with at least 1GB RAM, and 4GB storage. So I understood the stick would only work attached with 64-bit Intel or AMD processors, and ARM development boards would not be an option. But today, I’ve found that Movidius had uploaded a new video showing a Python based object recognition demo with the Neural Compute Stick connected to the the Raspberry Pi 3 board. You just need to add a USB camera, copy ncapi directory from the SDK installed on your Ubuntu 16.04 development machine to the Debian Jessie installed on RPi 3 […]

Buy Raspberry Pi 2 Board for Just $19.50 (Promo)

With the launch of Raspberry Pi 3 last year, there’s been much less interest for the Raspberry Pi 2 board, especially there has not been any official price cut. But Seeed Studio has an interesting promotion right now where the company sells Raspberry Pi 2 board for just $19.50, or $20 off the normal price on their website. That price does not include shipping, but this can apparently be combined with TENOFFSHIP coupon to bring the total price with shipping to Germany to $21.66. If the same laws are still in place, it’s below the 22 Euros limit in Europe meaning you won’t need to pay for VAT or custom duties on the board. You need to use the coupon before July 31, midnight (GMT+8), so there are only a few hours left. The main downside is that only 10 are available on backorder with shipping scheduled for August 11.

Manga Screen 2 is Smartphone Touchscreen Display with USB and HDMI Ports for Makers (Crowdfunding)

Most touchscreen displays aimed to be connected to a development board work through a display interface such as MIPI DSI or LCD RGB (and USB or I2C for touch support), and come with somewhat low resolution such as 800×480 which can be suitable for HMI applications. They also often don’t work with all boards due to the different interfaces used, and there’s no way to easily connect such small display to your computer. Taking those limitations into account, and since most boards and computers come with HDMI and USB ports, Elias Bakken and his team have added HDMI and USB ports to two smartphone displays, and Manga Screen 2 was born. The two displays – made by Sharp – have the following hardware specifications: Big (5.9”) Small (4.8”) Resolution 1920×1080 1280×720 FPS (max) 60 57 Color mode 24-bit PPI 376.2 307.9 Brightness 400 cd/m2 500 cd/m2 Contrast ratio 1000:1 800:1 […]

ModBerry Industrial Automation Controllers Leverage Raspberry Pi, FriendlyELEC, and AAEON Boards and Modules

TECHBASE’s ModBerry Linux based industrial controllers have been around since 2014 with their first model being ModBerry 500 powered by a Raspberry Pi compute module. Over the years, the company has kept adding new ModBerry controllers with now an interesting choice of Raspberry Pi 3 board or compute module, FriendlyELEC’s NanoPi M1 Plus board, or Intel Atom x5 based AAEON’s UP board. All programmable automation controllers (PAC) runs Linux 4.0 or greater, with Debian or Ubuntu Core rootfs including ready tools and pre-compiled packs including C/C++, JAVA, SQL, PHP, SSH, and VPN support. The firmware is upgradeable over the air, and the controllers can run the company’s iMod control software and interface with iModCloud cloud computing service for telemetry, remote control and data sharing. Typical uses include C-L-V functions with conversion to collect and transmit data over communication interfaces, logging via iModCloud or a SCADA, and visualization via a web […]

Microsoft Releases Raspberry Pi 3 Web Simulator Working with Azure IoT Cloud

If you were already following this blog when the first Raspberry Pi launched, you may have tried to emulate a Raspberry Pi and run Fedora in QEMU, as getting a board was a challenge at that time. Microsoft has launched its own Raspberry Pi (3) simulator running in web browsers, connecting to virtual sensors and components using Fritzing, and interfacing with the company’s Azure IoT cloud service. The preview version of the simulator does not allow you customize components on the breadboard, something you’ll be able to do in the release version, so we are stuck with a BMP280 sensor and red LED in the assembly window. on the left. On the top right, we’ve got sample source code written using Node.js to read temperature data from the sensor, push it to an Azure IoT Hub, and blink the LED in the coding area, and finally the integrated console window […]
