BBC Dr Who HiFive Inventor Coding Kit review – Tynker visual programing and MicroPython

HiFive Inventor review

The BBC Doctor Who HiFive Inventor Coding Kit was announced at the end of November 2020 with the goal of teaching IoT to young kids. But one day,  I noticed the postman left a package on the ground right next to my house’s gate for some reason. I had no idea what it could be until I read it was from SiFive on the package. So here I am about to review BBC Doctor Who HiFive Inventor Coding Kit! The package actually included two small packages with one being an “expansion board”… HiFive Inventor Coding Kit Unboxing We’ve already written about the specs in the announcement post, but here they are again for those who forgot it’s based on SiFive FE310 RISC-V microcontroller and ESP32 for WiFi and Bluetooth. Let’s open the thinner “expansion board” package first. It’s actually the HiFive Inventor board – aka the mainboard – that comes […]

OneGx1 Pro 7-inch 5G mini laptop features Intel Core i7-1160G7 processor

OneGx1 Pro

Last summer, One Netbook unveiled OneGx1 mini laptop powered by an Intel Core i5-10210Y Amber Lake processor with support for WiFi 6, 4G LTE, and/or 5G connectivity. The company has now come up with an update with a similar design, except OneGx1 Pro mini laptop features a more powerful Intel Core i7-1160G7 Tiger Lake UP 4 processor with four cores clocked at up to 4.4 GHz, and a 96EU Intel Iris Xe Graphics. OneGx1 Pro mini laptop specifications: SoC – Intel Core i7-1160G7Y Tiger lake UP4 quad-core/octa-thread processor @ 1.2 GHz (base) / 4.4 GHz (turbo one core) / 3.6 GHz (turbo all cores) with 96 EU Intel Iris Xe Graphics @ 1.1 GHz; 12MB cache; 7-15W TDP System Memory – 16GB LPDDR4/4X-4266 Storage – 512GB M.2 NVMe SSD, M.2 socket for an additional M.2 2242 SSD up to 2TB, MicroSD card slot Display – 7-inch 1920 x 1200 multi-touch […]

Yeelight Smart LED Bulb M2 (Multicolor) Supports Google Home Seamless Setup

Yeelight Google Home Seamless Setup

At the beginning of the year, I reviewed Yeelight Smart LED Bulb 1S with both the Yeelink Android app and Google Home app. The light bulb was one of the first to implement support for Google Home Local SDK which makes controlling the light bulb much faster but requires a Google Home compatible hardware platform such as Google Home Mini smart speaker. Using the light with Google Home app still required a Xiaomi account and go through some hoops, and that’s why Yeelight has now launched the Smart LED Bulb M2 (Multicolor) with support Google Home Seamless Setup. The Yeelight app is not needed anymore, and setup is easier with Google Home. All you need is a Google Assistant-enabled device like a Google Nest Mini or Google Nest Hub. Yeelight Smart LED Bulb M2 specifications: Bulb Interface – E26/E27 bulb Wattage – 8W Brightness – Up to 1000 lumens (equivalent […]

Linux 5.10 LTS release – Main changes, Arm, MIPS and RISC-V architectures

Linux 5.10 release

Linus Torvalds has just released Linux 5.10: Ok, here it is – 5.10 is tagged and pushed out. I pretty much always wish that the last week was even calmer than it was, and that’s true here too. There’s a fair amount of fixes in here, including a few last-minute reverts for things that didn’t get fixed, but nothing makes me go “we need another week”. Things look fairly normal. It’s mostly drivers – as it should be – with a smattering of fixes all over: networking, architectures, filesystems, tooling.. The shortlog is appended, and scanning it gives a good idea of what kind of things are there. Nothing that looks scary: most of the patches are very small, and the biggest one is fixing pin mapping definitions for a pincontrol driver. This also obviously means that the merge window for 5.11 will start tomorrow. I already have a couple […]

Bootterm – a developer-friendly serial terminal program

There are plenty of terminal programs to access the serial console from minicom or screen to Putty. But Willy Tarreau was not quite happy with those tools, so he decided to write his own: Bootterm. I was terribly fed up with the current state of serial terminals, which either don’t cope well with errors, or take ages to start, making you lose the first characters, or don’t support non-standard speeds etc. I finally wrote mine to address all that at once, plus support for automatic port detection (the last registered one is the good one by default), waiting for the port to be ready, and also support fixed or timed captures. And a few environment variables make it possible not to type any argument at all yet have the expected behavior. If that’s something of interest to you, you can check it there: https://github.com/wtarreau/bootterm It’s still young (no support for […]

Banana Pi BPI-M5 SBC with 4GB RAM, 16GB flash launched for $53

Banana Pi BPI-M5

Last September, we wrote Banana Pi team was working on an Amlogic S905X3 SBC called BPI-M5 and very similar to Hardkernel ODROID-C4 board launched in April 2020. At the time, we noted the Banana Pi BPI-M5 did add a 16GB eMMC flash on-board by default, while ODROID-C4 requires booting from a MicroSD card or a separate eMMC flash module. We also pointed out software and community support is usually much better for the ODROID board, and it was brought to our attention that BPI-M5 board uses 5V voltage only via USB-C, while the Hardkernel board support a wider 5.5V to 17V via a power barrel jack, and this could lead to potential power issue for customer connecting drives to USB 3.0 ports. The good news is that you can now buy Banana Pi BPI-M5 SBC on Aliexpress for $53 plus shipping. Banana Pi BPI-M5 specifications haven’t changed, and we can […]

OpenTitan and Microsoft Pluton – The security chips of the future

OpenTitan Security Model

Security is becoming more and more important with critical data exposes to the Internet. Traditionally some PCs, laptops, motherboards, or single board computers would be equipped with a TPM (Trusted Platform Module) designed to secure hardware through integrated cryptographic keys.  More recently, we’ve started to read more and more about secure elements providing hardware-based security for lower-end platforms. Those are external chips, but companies have also started to providing hardware-security within the processor with solutions such as Arm Trustzone or Intel SGX (Software Guard Extensions). But more recently, Google and Microsoft have made announcements about hardware-security IP with respectively OpenTitan open source project and Microsoft Pluton security chip both meant to be embedded into processors. OpenTitan OpenTitan is described as being “the first open-source project building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips”. It is backed by Google, Seagate, Nuvoton, Western Digital, […]

NanoPi R4S SBC preview with OpenWrt and Ubuntu Core

NanoPi R4S review

Rockchip RK3399 powered NanoPi R4S router SBC launched at the beginning of the month, and FriendlyELEC kindly sent a review sample to CNX Software. I intended to test thermally performance, Ethernet, and USB like I did for NanoPi R2S and NanoPi NEO3,  but Armbian is not available right now, so I could not use some of the tools I normally used right now. So instead, I tested the board/gateway with the image from FriendlyELEC. First FriendlyCore based on Ubuntu Core 20.04, but there some issues which we’ll detail in this preview, so I then switch to FriendlyWrt built upon OpenWrt 19.07 which works better, but I still encountered some problems. That’s just to say it might be better to wait a little longer until Armbian images are released, or until FriendlyELEC fixes some of the shortcomings. NanoPi R4S gateway unboxing Before testing the software, let’s see what I’ve received. NanoPi […]
