Arm’s Platform Security Architecture Aims to Secure the Internet of Things (IoT)

News are published nearly everyday about a security breach or flaw in IoT devices, and last year, Softbank CEO, and new Arm owner, Masayoshi Son explained that to reach his goal of one trillion IoT devices and singularity, security had to be addressed, as everything was currently too easily hackable, including cars equipped with lots of electronics but very weak security. As Arm Techcon 2017 is underway, the company has been working on improving IoT security and announced the Platform Security Architecture (PSA) designed for low cost IoT devices. PSA has three major components: Threat Models and Security Analyses derived from a range of typical IoT use cases. Architecture specifications for firmware and hardware. An open source project, similar to Arm Trusted Firmware for mobile clients. PSA is designed for low cost IoT devices, which would have not the resources (processing power, memory, battery power…) to run a full Trusted […]

Tronxy X3S 3D Printer Review – Part 2: Upgraded Heatbed and RAMPS Board

Karl here. So the bed I mentioned in the first part of Tronxy X3S review is not very good. It took about 10-11 minutes to heat up to 60 deg Celsius. I also mentioned I was going to upgrade the board to a RAMPS board. Today we are going to look at both these upgrades. New Heated Bed I can take no credit for this one but I wanted to pass this along. Folger tech sells a 12v 280w heated bed stick on pad. I picked this up for $20, but is now $22. In order to do this upgrade you will need a MOSFET, 12V/30A power supply, and of course the pad above. Super easy installation. Remove the bed and stick on the self adhesive pad centered. Replace the power supply with new one. Should be self explanatory. In order to power this bed a MOSFET is needed. A […]

Nerdonic Exen Mini is the World’s Smallest 32-bit Arduino Compatible Board (Crowdfunding)

Back in June, we reported about μduino board, which at 12×12 mm may well be the world’s smallest Arduino compatible board. It is based on Microchip Atmel ATMEGA32U4 8-bit AVR microcontroller. But there’s now a new board in town which claims to be the world’s smallest 32-bit Arduino board: Exen Mini measuring 14.9×14.9 mm. While I’m patiently waiting for an Intel’s DMCA request, or more likely an email requesting an update once the name has changed, like I had to do for Atomwear Vigekwear, let’s have a look at what the board has to offer. Exen Mini specifications: MCU – Microchip Atmel SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM I/Os via 2x 5-pin 2.54mm pitch headers Up to 8x digital I/O Up to 8x PWM Up to 6x analog (ADC) 1x UART 1x I2C 1x reset Limits – 3.7V, 7mA USB – 1x micro USB […]

JeVois Smart Machine Vision Camera Review – Part 1: Developer / Robotics Kit Unboxing

JeVois-A33 computer vision camera was unveiled at the end of last year through a Kickstarter campaign. Powered by an Allwinner A33 quad core Cortex A7 processor, and a 1.3MP camera sensor, the system could detect motion, track faces and eyes, detect & decode ArUco makers & QR codes, follow lines for autonomous cars, etc.. thanks to JeVois framework. Most rewards from KickStarter shipped in April of this year, so it’s quite possible some of the regular readers of this blog are already familiar the camera. But the developer (Laurent Itti) re-contacted me recently, explaining they add improves the software with Python support, and new features such as the capability of running deep neural networks directly on the processor inside the smart camera. He also wanted to send a review sample, which I received today, but I got a bit more than I expected, so I’ll start the review with an […]

Voladd Cloud-Connected Linux 3D Printer is Powered by BeagleBone Black Board (Crowdfunding)

So far, all of the 3D printers that have been reviewed on this blog require you to design or download a 3D object on your computer, and print it from an SD card. But thanks to OctoPrint software and cheap ARM Linux developments boards, it has become possible to add a Linux computer with webcam to remotely start and control the 3D printer for a few dozens dollars. Karl has even released an OctoPrint image for Orange Pi Lite board. Voladd 3D printer already embeds a Linux board, namely the BeagleBone Black running Debian, which allows the 3D printer to be easy to use since no software installation is required. You can start printing by selecting an object in a web browser or an app in your smartphone, and they’ve also taken steps to eliminate/reduce maintenance tasks, such as the inclusion of a filament cartridge. Voladd 3D printer specifications: Internal […]

AMBE+2 Vocoder Promises High Voice Quality at Low (2.0 to 9.6 Kbps) Data Rates

Opus 1.2 open source audio codec was release a few months ago with the ability to deliver low power low high-quality audio bitrate for speech with bitrates as low as 12 Kbps. Digital Voice Systems (DVSI) claims to have gone even lower thanks to their AMBE+2 vocoder (Advanced MultiBand Excitation) providing high-quality speech at data rates from 2.0 to 9.6 kilobytes per second. AMBE+2 vocoder is said to outperform the company’s previous generation AMBE+ Vocoder as well as the G.729 and G.726 vocoders, while operating at only 4.0 Kbps. The vocoder is suitable for mobile radio, secure voice, satellite communication, computer telephony, digital voice and storage applications The solution can be integrated into product either using software licensing, or through Vocoder chips, and the company lists the following key benefits: Maintains speech intelligibility and speaker recognition at rates as low as 2.0 kbps Resistant to background noise and channel bit errors […]

Synaptics Introduces VideoSmart BG5CT 4K HDR Multimedia Video Processor for Set-Top Boxes

Marvell used to design Media SoCs running Android TV such as ARMADA 1500 Ultra (aka BG4CT). That part of Marvell business has very recently been sold to Synaptics, which has just unveiled VideoSmart BG5CT multimedia SoC with 4K “Advanced” HDR video processing for the set-top-box market. The BG5CT is said to be pin-to-pin compatible with BG4CT Android TV SoC, features a quad core ARM CPU @ 1.6 GHz with 15K DMIPS, an Imagination PowerVR Series8XE GE8310 GPU, and a security engine enabling secure boot, Trusted Rendering Path, full TrustZone, and video watermarking carrier-grade security making it suitable for Pay TV operators and set-top-box manufacturers. Synaptics’ Qdeo video processing technology adds 4K “Advanced HDR” – including HDR10, HLG, Dolby Vision, and Technicolor HDR, among user video processing technology. The company did not provide that many details, but BG5CT appears to mostly add HDR support compared to BG4CT, and replace Vivante GC7000 GPU by […]

MeLE PCG35 Apo Mini PC Review – Part 2: Windows 10 Home

Laptops and mini PCs powered by the new generation of Intel Gemini Lake processors are coming soon, but companies are still launching Apollo Lake based products with various features. MeLE PCG35 Apo mini PC is one of them, and what makes it interesting compared to most of the competition is support for 80mm M.2 SSDs and 2.5″ SATA drives, on top of featuring a Celeron J3455 processor, one of the most powerful of the family. I took photos of the mini PC, accessories, and internal design in the first part of the review, so I’ll report about my experience with Windows 10 Home, explain how to manage the different drives, and test stability under load. MeLE PCG35 Apo Setup, Drives Configuration, Display Settings Last time, I’ve showed how to install an M.2 SSD and 2.5″ SATA hard drive inside MeLE PCG35 Apo, so I just have to connect a few […]
