Updating Star Cloud PCG02U to Ubuntu 16.04 with WiFi and HDMI Audio Support

I completed my review of PCG02U Ubuntu TV stick a few days ago, and I was quite satisfied with the device, but since Ubuntu 16.04 was released last month, I thought it might be fun to upgrade to the latest version of Ubuntu. I’m go through the complete steps including building a new kernel for HDMI audio, and the drivers for WiFi, but you should be able to install Ubuntu 16.04 for Bay Trail and Cherry Trail processor with the image made by Linuxium and a USB stick. Star Cloud PCG02U OS Support and Warranty Before I go through the instructions, you may want to read the conditions on MeLE’s Aliexpress PCG02U page. They meant Ubuntu 14.04 instead of 14.0.4, but the important part is that if something goes wrong trying alternative OS, you may lose your warranty. Upgrade Ubuntu 14.04 to Ubuntu 16.04 Upgrading from one LTS version to […]

Getting Started with Wio Link Starter Kit, Visual Programming Android App, and IFTTT

Wio Link is a board based on ESP8266 WiSoC that is supposed to be easy to set up thanks to Grove modules – no breadboard and mesh or wires – and, as I first understood it, to program thanks to a drag-and-drop mobile app that does not require any actual programming. More advanced users can also use a RESTful API in Python, JavaScript, Node.js, PHP, Objective-C or Java. I’ve been sent a $49 Wio Link Starter Kit including the board, a USB cable, and six Grove modules to evaluate the kit. I’ll start by having a look a the kit, before experimenting with the Wio Link Android app. Wio Link Starter Kit Unboxing The kit is sent in a red plastic case. Wio Link board is lodged in the top cover, and other accessories are placed in bags in the main part of the case. Let’s check the board first. […]

How to Run Ubuntu 16.04 Aarch64 (64-bit ARM) Cloud Images on Your Intel/AMD Linux Computer with QEMU

With the recent launch of several low cost Cortex A53 development boards, 64-bit ARM hardware is now pretty common and inexpensive, but if you want to run 64-bit ARM code on your x86 Linux computer, Riku Voipio, a software engineer working for Linaro, wrote some instructions to run Ubuntu 16.04 Aarch64 Cloud image in QEMU. Ubuntu cloud images are “the official Ubuntu images and are pre-installed disk images that have been customized by Ubuntu engineering to run on public clouds that provide Ubuntu Certified Images, Openstack, LXD, and more. ” So the instructions are also useful if you want to easily try such packages on 64-bit ARM platform. I’ve tried those instructions myself on my Ubuntu 14.04 machine with and AMD FX8350 processor, and they worked pretty well, and the only things I had to find out by myself was to install a recent version of qemu. First, we’ll need […]

Debian on DragonBoard 410c Development Board

I purchased Qualcomm DragonBoard 410c development board last year, and first tested it and run some benchmark on the 96Boards compliant hardware with Android. I found that it was still work-in-progress, and decided to wait before trying Debian on the board. I’ve now done so, and will report by experience installing Debian Linux, playing with the board, and running Phoronix benchmarks to compare it to other ARM Linux boards. Installing Debian on DragonBoard 410c The first challenge is to navigate through the documentation that is not always clear or up-to-date. I eventually ended up on DragonBoard 410c Wiki on Github. You then have to decided which image you want. While there are two official operating systems with Android and Debian, you can three “entities” releasiong their own images. For Debian specifically, you have the Linaro image, and Reference Platform Build (RPB) image. I could not find any changelog or known […]

How to Change Language to English and Install Apps Remotely on Xiaomi Mi Box 3 Enhanced

Just like other Xiaomi TV boxes the latest Xiaomi Mi Box 3 Enhanced (aka MiBox 3 Pro) comes with a Chinese only user interface, but a similar method as used for Xiaomi Mi Box Mini to change English and remotely install apps. I’ve gone through this and taken pictures and screenshots to show how to change the language. I had connected the HDMI cable, a USB hard drive, as well as a USB keyboard and RF dongle for my airmouse and gamepad to the device, and after powering up the device, you are know some text in Chinese, you can press OK, and you’ll soon be presented with a list of WiFi access points. Select one, and you’ll be asked to input the password for the network. However, in my case I had no connect button, and pressing OK on the remote did not work at all. It turns out […]

Atmel MCU Madness is an informal competition on Twitter where people vote for their favorite development boards. We are now at the quarter finals, and beside the usual suspects such as Raspberry Pi and ESP8266 boards, I also noticed one board that I had never heard of: AXEL Elettronica’s SmartEverything based on Atmel SAM D21 Cortex M0+ and featuring SigFox, BLE, NFC, and GPS connectivity, as well as various sensors such as humidity and temperature, 9-axis motion sensor, and so on.

Stream Live TV to Your Computer or Smartphone with U4 Quad Hybrid Android TV Box, Kodi and TVheadend

TVheadend is a streaming server and recorder for Linux, FreeBSD and Android supporting DVB-S, DVB-S2, DVB-C, DVB-T, ATSC, ISDB-T, IPTV, SAT>IP and HDHomeRun as input sources, and while in theory it should be possible to configure any recent Android TV set-top box with digital TV tuners, configuration is complex, and there’s no guarantee the tuner will be recognized. However, the manufacturer of U4 Quad Hybrid has already configured their box to support HTSP clients, so I’ve installed the latest firmware, and given it a try with my Android smartphone running Kodi 15.2 with TVheadend HTSP client, and I could successfully stream live TV (DVB-T2 free-to-air channels) to my smartphone. Once you’ve scanned the channels using DVB-T2 and/or DVB-S2, there’s no other configuration in U4 Quad Hybrid TV box, but you’ll still need to find out your IP address by going to Setup->Network, and WiFi, Ethernet or 3G depending on your […]

Getting Started with Wemos D1 mini ESP8266 Board, DHT & Relay Shields

Wemos D1 mini is an ESP8266 board that’s interesting thanks to its size, its low price ($4), micro USB power, its shields, and a documentation that looks fairly good. The board can be programmed with Arduino or Lua, and supports both serial and OTA programming. I’ve decided to give it a try and bought the board together with two temperature shields, a relay shield, and micro SD shield. I got all for $ 14.00 from Wemos Aliexpress shop, and it took about one month for delivery. I can also see they’ve recently released a new OLED shield selling for about $5. All shields were shipped inside their own anti-static bags. The pins are clearly marked on both side of the board and the shields. One side of the board features ESP8266 module. and the other side has CH340 serial to USB chip, and the reset button. The provided headers make […]
