How to Use CHIP Board as a Linux Printer & Scanner Server

We have a Canon Pixma MP250 series multi-function USB printer connected to a Windows 10 laptop at home, and for several years, I had no problems printing from my Ubuntu computer to that printer. However, this setup recently stopped to work, and whatever I would do, printing would never start from my Ubuntu PC, even though the file was (allegedly) successfully transfered to the Windows 10 laptop connected to the printer. So I decided to setup my own printer server, as well as a scanner server since it’s a multi-function printer, using one of the boards from my collection. As I opened my cabinet, I wondered whether I would use an Orange Pi board, Raspberry Pi board, or Nano Pi board, but I needed WiFi since there’s no Ethernet in the office where the printer is located, and I found that Next Thing CHIP board was the ideal candidate as […]

CHUWI LapBook 14.1 Windows 10 Firmware, Drivers, and BIOS

In case you’ve installed another operating system like Ubuntu on CHUWI Lapbook 14.1 laptop, and want to re-install Windows 10, CHUWI has released Windows 10 firmware, drivers, and LapBook 14.1 “BIOS” in their forums. So I’ve re-installed Windows 10 on the laptop using the Windows 10 image. You’ll need to download the 8 files CHUWI LapBook 14.1 Windows.part1.rar to CHUWI LapBook 14.1 Windows.part8.rar, and after extracting them you should get a “CHUWI LapBook 14.1 Windows” directory with all necessary files to reinstall Windows. The files take 8GB, so it may not fit on all 8GB flash drives, and you may need to use a 16GB or greater drive. I just copied the files to an 64GB flash drive formatted with NTFS, insert the drive into the USB 2.0 port of the laptop, and I could start the installation process at boot time. However, it quickly failed as it tried to […]

How to Upgrade to Linux 4.8 in Ubuntu 16.04.2

I had read from several news sources that Ubuntu 16.04.2 would come with Linux 4.8. My system was upgraded from Ubuntu 16.04.1 to Ubuntu 16.04.2 this week-end, but I still had Linux 4.4.

So I wondered why that was, and eventually found my answer on Reddit thanks to EndofLineLF user: If it isn’t a new 16.04.2 installation then you won’t have newer kernel. If your install started as 16.04 or 16.04.1 then with all updates installed “lsb_release” will display 16.04.2 as version because that’s what you have. The switch to HWE (Hardware Enablement Stack) was never automatic. So if you want newer kernel you have to install it manually. https://wiki.ubuntu.com/Kernel/RollingLTSEnablementStack#Packages-1 sudo apt-get install –install-recommends xserver-xorg-hwe-16.04 This will also install the new HWE kernel because it is recommended for that package. Upgrading to the new kernel is completely optional, and Linux 4.4 will still get security updates, but I did […]

Review & Quick Start Guide for Khadas Vim Pro Development Board with Ubuntu 16.04

Khadas Vim is the only Amlogic S905X development board I’m aware of. There are 4 or 5 versions of the board, but currently only two models are sold: Khadas Vim with 8GB flash and single band WiFi + BLE 4.0, and Khadas VIM Pro with 16GB flash, and dual band WiFi + BLE 4.2. SZWesion, the company behind the board, has sent Khadas Vim Pro for evaluation. Today, I’ll take a few pictures of the board and its accessories, and report my experience playing with Ubuntu 16.04.2 on the board. They’ve also released Android, LibreELEC, and dual boot Android/Ubuntu (for Vim Pro only) images, which you can find in the firmware resources page. Khadas Vim Pro Unboxing and Photos My parcel included Khadas package that looks like a book, an HDMI cable, and the same IR remote control sent with GeekBox, the first board made by the company, and powered […]

How to Use IPVanish VPN Service on an Android TV Box to Stream Videos from Anywhere

A few days ago, I completed the review of EBox T8 V Android TV box geared towards the UK market and/or people who want to watch UK content. However this time I did not spent that much time on the IPTV / streaming apps, as I had already checked out in EBox T8 4 TV box review last year, and many apps and/or TV programs required an IP address in the UK to work. For example, BBC iPlayer would throw the following error message each time I tried to play a video. Normally, you can work around this using a DNS or VPN service, but it’s not something I really need so I did not investigate further. However, IPVanish contacted me a few days after EBox T8 V review, and I asked whether I could get a test account for their VPN service to try it in EBox T8 V, […]

LibreELEC (Kodi Linux) on Voyo V1 VMac Mini Apollo Lake Mini PC

I’ve just posted Voyo V1 VMac Mini review with Windows 10 this morning, and at the end I mentioned I quickly tried to run Ubuntu 16.04 without success. Reader Piotr who also happens to be a LibreELEC together with about 65 other team members, noticed it, provided me a link to a development version of LibreELEC 8.0 (mirror link) working with Apollo Lake processors, and explained Ubuntu was not working because Linux needs updated Mesa and Intel drivers. The image is based on Linux 4.10-rc5 with the necessary drivers and Kodi 17. The changes were mostly made by FernetMenta (Rainer Hochecker), and will be merged in Linux 4.10 and Mesa 17.0. He also implemented 10-bit HEVC support that will officially be available in Kodi 18 only and found in daily builds. So let’s try this out. After downloading LibreELEC-Intel.x86_64-8.0-devel-20170130110609-r25167-gd210441.img.gz, I tried to flash it (N.B.: no need to extract it) […]

How to use Sonoff POW with ESPurna Firmware and Domoticz Home Automation System

Sonoff POW is an ESP8266 based wireless switch with a power meter that comes pre-loaded with a closed-source firmware that works with eWelink app for Android or iOS by default. But we’ve also seen Sonoff POW, and other Sonoff wireless switches from the same family, can be flash with open source firmware supporting MQTT (Message Queuing Telemetry Transport) lightweight messaging protocol such as ESPurna, and I initially sent data from Sonoff POW to ThingSpeak via an MQTT broker (mosquitto) to draw some pretty charts. I did that with the switch connected to a lightbulb, but I’ve since installed Sonoff POW in my office to measure the room’s power consumption minus the ceiling light and aircon as shown below. Sonoff cable mechanism is really a pain for hard copper wires, as they are hard to push inside the mechanism, and something come out. I finally managed by it took longer than […]

How to Install Domoticz Home Automation System in NanoPi NEO and Other ARM Linux Boards

I’ve recently started experimenting with IoT projects, and the first hurdle is to select the hardware and software for your projects are there are simply so many options. For the hardware your first have to choose the communication protocols for your sensors and actuators, and if you are going to go with WiFi, ESP8266 is the obvious solution, used together with your favorite low cost Linux development board such as Raspberry Pi or Orange Pi to run some IoT server software locally or leveraging the cloud. But the most difficult & confusing part for me was to select the server software / cloud services as there are just so many options. I prefer having a local server than something running only in the cloud, as my Internet goes a few hours a month, so I started with a solution combining ThingSpeak with MQTT gathering data from Sonoff power switches running […]
