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 […]

IkaScope WiFi Oscilloscope Probe Works with Windows, Linux, Mac OS X, Android and iOS

Last year, I wrote about Aeroscope, a portable Bluetooth oscilloscope that looks somewhat like a Stabilo Boss highlighter pen, and sends measurements over the air directly to your Android and iOS tablet or smartphone. It was introduced through a crowdfunding campaign which eventually failed, but Aeroscope can now be purchased for $199 on Amazon US or their own website. If you’d prefer WiFi over Bluetooth, and would like something that also works on Windows, Linux, and/or Mac OS X, IKALOGIC has just launched IkaScope WiFi oscilloscope probe compatible with all popular mobile and desktop operating systems. IkaScope WS200 specifications: Analog Bandwidth  – 30 MHz @ -3dB Sample Rate – 200 MSps Connectivity – 802.11 b/g/n/e/i WiFi @ 2.4 GHz configurable as access point or station Input Range – +/-40 V range CAT1 Offset Range – +/- 20V to +/- 40V offset Input Impedance – 10MΩ || 14pF Input Contact – […]

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 […]

GOLE1 Plus Windows 10 mini PC & Tablet Combo Coming Soon for Around $200

GOLE1 was product launched last year than combined a tablet and mini PCs functionalities into one product with a 5″ touchscreen, a battery, and all the ports you’d expect from a mini PC with USB, HDMI, etc… I reviewed an early GOLE1 sample running both Windows 10 and Android 5.1, and beside a battery charging problem due to its being one of the first sample, I found it was a product fun to play with, however, I could not really find a practical use case for it. The 5″ display is just to small to run Windows 10 comfortably, and it’s a bit heavy to use like a normal tablet. Maybe if you have an application that require a small display panel to  control a large screen connected via HDMI, it’s different. I’ve been informed the company is about to launch a new version, called GOLE1 Plus, with a new […]

Linux 4.8 Release – Main Changes, ARM & MIPS Architectures

Linus Torvalds has officially released Linux 4.8 last Sunday: So the last week was really quiet, which maybe means that I could probably just have skipped rc8 after all. Oh well, no real harm done. This obviously means that the merge window for 4.9 is open, and I appreciate the people who already sent in some pull requests early due to upcoming travel or other reasons. I’ll start pulling things tomorrow, and have even the most eager developers and testers hopefully test the final 4.8 release before the next development kernels start coming 😉 Anyway, there’s a few stragging fixes since rc8 listed below: it’s a mixture of arch fixes (arm, mips, sparc, x86), drivers (networking, nvdimm, gpu) and generic code (some core networking, with a few filesystem, cgroup and and vm things). All of it pretty small, and there really aren’t that many of them. Go forth and test, […]

GOLE1 mini PC Tablet Review – Part 2: Android 5.1 and Windows 10

GOLE1, also called GOLE1 F1, is an interesting device because it’s quite difficult, it’s like the offspring of a mini PC and a tablet with a smallish  phone-like 5″ capacitive touch screen. It also dual boot Windows 10 and Android 5.1. I’ve already discussed about the hardware, and taken picture of the device, accessories, and motherboard, in the first part of the review, so today I’ll report my experiences with Windows 10 and Android 5.1, as well as the potential use cases. Since I’ve already reviewed Intel Atom x5-Z8300 mini PCs, as well as a dual boot Windows and Android Intel mini PC, I’ll focus on what makes GOLE1 different in this review. GOLE1 Dual Boot and Use Cases I normally check my emails on my smartphone while having breakfast in the morning, but one day the charging micro USB cable was not connected properly to my phone, so I […]

Embedded Linux Conference & IoT Summit Europe 2016 Schedule

Embedded Linux Conference & IoT summit 2016 first took place in the US in April, but the events are now also scheduled in Europe on October 11 – 13 in Berlin, Germany, and the schedule has now been published. Even if you are no going to attend, it’s always interesting to find out more about the topic covered in that type of events, so I had a look, and created my own virtual schedule with some of the sessions. Tuesday, October 11 10:40 – 11:30 – JerryScript: An Ultra-lightweight JavaScript Engine for the Internet of Things – Tilmann Scheller, Samsung Electronics JerryScript is a lightweight JavaScript engine designed to bring the success of JavaScript to small IoT devices like lamps, thermometers, switches and sensors. This class of devices tends to use resource-constrained microcontrollers which are too small to fit a large JavaScript engine like V8 or JavaScriptCore. JerryScript is heavily […]

Linux 4.7 Release – Main Changes, ARM and MIPS Architectures

Linux 4.7 is out: So, after a slight delay due to my travels, I’m back, and 4.7 is out. Despite it being two weeks since rc7, the final patch wasn’t all that big, and much of it is trivial one- and few-liners. There’s a couple of network drivers that got a bit more loving. Appended is the shortlog since rc7 for people who care: it’s fairly spread out, with networking and some intel Kabylake GPU fixes being the most noticeable ones. But there’s random small noise spread all over. And obviously, this means that the merge window for 4.8 is open.Judging by the linux-next contents, that’s going to be a bigger release than the current one (4.7 really was fairly calm, I blame at least partly summer in the northern hemisphere). Linus Linux 4.6 brought USB 3.1 superspeed, OrangeFS distributed file system, 802.1AE MAC-level encryption (MACsec), and BATMAN V protocol support, improved […]
