Embedded Linux Conference & Open Source Summit Europe 2017 Schedule

The Embedded Linux Conference & IoT summit 2017 took place in the US earlier this year in February, but there will soon be a similar event with the Embedded Linux Conference *& Open Source Summit Europe 2017 to take up in Europe on October 23 – 25 in Prague, Czech Republic, and the Linux Foundation has just published the schedule. It’s always useful to find out what is being discussed during such events, even if you are not going to attend, so I went through the different sessions, and compose my own virtual schedule with some of the ones I find the most interesting. Monday, October 23 11:15 – 11:55 – An Introduction to SPI-NOR Subsystem – Vignesh Raghavendra, Texas Instruments India Modern day embedded systems have dedicated SPI controllers to support NOR flashes. They have many hardware level features to increase the ease and efficiency of accessing SPI NOR […]

Beelink AP34 Ultimate Fanless mini PC Review with Windows 10 and Ubuntu

The AP34 Ultimate combines the passive cooling of an Apollo Lake N3450 SoC with 8GB of RAM and 64GB of storage in a small box form-factor mini PC. Together with the device comes a pair of HDMI cables, a power adapter, VESA mount with screws, and a couple of leaflets covering basic information. Not only does this device have three USB 3.0 ports, full size SD card, Gigabit Ethernet, headphone jack and HDMI port, it also has a (vacant) M.2 slot allowing additional storage with the full specification being: although there was no included remote control. The device comes pre-loaded with activated Windows 10 Home 64-bit and plenty of available free space at (initially before updates) just over 43GB. The Windows performance is unremarkable and the reason for this is obvious looking at the basic benchmarks. The reason being that the eMMC is slow which is disappointing for an ‘ultimate’ […]

Installing Let’s Encrypt Free SSL/TLS Certificate in 2 Minutes with Certbot, Spending Hours Making it Work with Cloudflare

I’ve been using an SSL certificate to the download subdomain of this blog running ownCloud for about 2 years, but recently my free StartSSL certificate expired, and I had troubles to renew it, and I also received an email from Google telling me that “Starting October 2017, Chrome (version 62) will show a “NOT SECURE” warning when users enter text in a form on an HTTP page, and for all HTTP pages in Incognito mode”. So I decide to use free LetsEncrypt SSL/TLS certificates to replace the one in the download subdomain, as well as this main blog. Such SSL/TLS certificates are also very useful for the IoT gateways many of use have started using, and I found it’s even simpler than install a self-signed certificate, so there’s no reason to use those anymore. The easiest way to install Let’s Encrypt certificate is by using Certbot with instructions for various […]

NComputing RX300 Thin Client Review – Part 1: Unboxing and Teardown

NComputing RX300 is a thin client based on Raspberry Pi 3 board that will allow to remotely run Windows and Linux operating systems from a much more powerful server, and Raspberry Pi 3 mostly handling the display, and connection to hardware like USB keyboard and mouse. The company has me sent a review sample for evaluation, and I’ll start by checking out what I received, and the hardware design of the device. NComputing RX300 Thin Client Unboxing I was asked whether I could test dual display, and then I had to choose between a VGA adapter or a DVI adapter. I selected the former, and I received both RX300 thin client, and a USB to VGA secondary adapter with its USB cable. We’ll find the thin client, a 5.1V/2.5A power adapter with a US plug adapter, and a multi-language quick installation guide in the package. The enclosure is really cute, and […]

Checking out Hologram’s Developer SIM Card for Worldwide IoT Projects

Hologram is a service that offers 2G/3G/4G cellular connectivity for the Internet of Things via a SIM card that works in over 170 countries, and with pricing starting at $0.40 per month. In order to promote their services, the company offers a free developer SIM card which I ordered when I first wrote about the service last month. I was pleased and surprised they would sent it to Asia for free, and I got the card in a bubble envelop. The back of the card includes a 18 to 22 digit SIM card number and bar code, that we’ll need to use for activation, and a link that redirects to https://hologram.io/docs/. I planned to try the card with Wio GPS tracker board which requires a nano SIM card, and there are convenient cutouts to convert the SIM card to micro SIM or nano SIM card formats. Before using the card […]

Videostrong VS-RD-RK3399 Development Board Review – Part 1: Unboxing, Kit Assembly, SDK and Documentation

Videostrong VS-RD-RK3399 development board is a full-featured development based on Rockchip RK3399 hexa-core processor with up to 4GB RAM, and 32GB eMMC flash, and plenty of I/Os. The company has sent me a sample, and after getting some trouble going through customs with questions like “what is a development board?” and “is it a board for TV boxes or computers?”, I finally got hold of the parcel. Today, I’ll check out the board and its accessories, show how to assemble it, and since the company shared more info about documentation and software, quickly go over what’s available. Videostrong VS-RD-RK3399 Development Kit Unboxing The board was in a bland carton box, which is fine since it’s not a consumer product, with a stick showing I got the 4GB LPDDR3 / 32GB eMMC flash version. There’s also a board using 2GB/16GB configuration. The package includes the board, bottom and top acrylic plates […]

Bqeel MVR9 (NT-N9) TV Box Review – Part 2: Android Nougat Firmware, RKMC, YouTube 4K, and More

Bqeel MVR9 is another TV box powered by Rockchip RK3328, but that model comes with Gigabit Ethernet and 2GB RAM contrary to the cheaper A95X R2 TV box I previously reviewed. If you want to check thsee some pictures read “Bqeel MVR9 TV Box Review – Part 1: Specifications, Unboxing and Teardown“, as in this second part I’ll focus on the firmware, and we’ll see if the claims of better 4K video playback thanks to DDR4, optimized RKMC with HD audio pass-through, YouTube 4K, and DRM support are true. First Boot, Setup, and First Impressions One good thing about Bqeel MVR9 is that it comes four 4 USB port, so I did not need to use a USB hub to connect my two RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, a Seagate USB 3.0 hard drive, and a USB keyboard I normally use […]

ECDREAM A9 Apollo Lake HDMI “TV Stick” Review with Windows 10 and Ubuntu 17.04

The ECDREAM A9 is arguably the first Intel Apollo Lake ‘PC stick’ available for purchase. However, in reality it is surprisingly large, and when compared to earlier Intel Atom ‘sticks’ and mini PC ‘boxes’ it lies somewhere in between. Measuring 2.3 inches (58 mm) wide and 0.6 inches (16 mm) thick it feels almost double in size of the original Intel Compute Stick (1.5 in/38 mm by 0.5 in/12 mm) and like nearly half of a mini PC (Beelink’s AP34 is 4.7 in/119 mm by 0.8 / 20 mm). Given that you only get two USB ports, an micro SD card slot and the obligatory HDMI and power port, the large size would be better justified if an Ethernet port had also been included given other smaller ‘sticks’ have shown this is possible. However the reason for its size is due to the oversized fan and heatsink… and that […]
