Most Android apps used to be programmed in Java with the Eclipse IDE, then Google introduced Android Studio in 2013 which has now replaced the latter, and with the release of Android Studio 3.0 Canary 1 preview, the company is now offering developers to program apps using Kotlin language instead of Java. Kotlin programming language is 100% compatible with Java language, and you can even mix Kotlin and Java in your code. Kotlin can make your code much more simple while declaring classes, and it has a few other improvements over Java. Android Studio also include a Java to Kotlin converter. The language has already been used by Expedia, Flipboard, Pinterest, Square, and others. Android Studio 3.0 also brings many other improvement, such as performance profiling tools for the CPU, memory, and networks showing your app performance in real-time, and faster Gradle builds for large sized app projects. Android Studio […]

Checking Fan Noise and Other Sound Levels with Benetech GM1352 Sound Level Meter
I wrote about UNI-T UT353 Sound Level Meter a few months ago as I thought it could be a neat way to measure fan noise on some TV boxes and mini PCs in an objective way. I finally ended up buying Benetech GM1352 model instead for $13.9 on DX (now available for $12.83 on Aliexpress or around $18 on Amazon), but I did not really use it so far, since I did not get a new device with a fan. I’ve now had the chance to try it since the Voyo VMac Mini mini PC comes with a fan. Let’s just go through some of GM1352’s key features first: Noise Levels & Accuracy – 30 to 130 dB with +/- 1.5 dB accuracy (94dB @ 1 KHz) Frequency Range – 31.5 to 8 KHz Measurement features – MAX/MIN & Data hold Display – 1.7″ LCD display with backlight Buttons – […]
Embedded Linux Conference and OpenIoT Summit Europe 2016 Videos are Now Available Online
The Embedded Linux Conference and OpenIoT Summit Europe 2016 conferences took place on October 11 – 13 in Berlin, Germany, with many interesting talks about Linux, development boards, power management, embedded systems, software optimization, tools, and so on, as well as a few keynotes. The Linux Foundation has recorded most talks and keynotes, and made the videos available on their website. A free registration is required, and will redirect you to the full unlisted playlist on YouTube. Tim Bird keynote can be watch directly without registration.

Amlogic USB Burning Tool Still Sucks in 2016
[Update November 2016: If you don’t like USB Burning Tool or don’t have the necessary USB cable, you can flash Amlogic IMG firmware to a micro SD card instead] In the first few years when Android TV Boxes/mini PCs started to hit the markets, in the 2012-2014 period, online firmware update was inexistent for the vast majority of the boxes, and if you wanted to update your firmware you had to use some windows tools like USB Burning Tool for Amlogic, AndroidTool for Rockchip, or PhoenixUSBPro / PhonixSuite for Allwinner platforms. All those tools have poor design, for example the window is not resizable, so it’s impossible to your an old netbook (1024×600 resolution), and then you have to install drivers which is easy, for after detection of the box may be hit and miss, and you have to follow a procedure with the right power sequence with a USB […]
UNI-T UT353 is a $15 Lightweight Sound Level Meter
Since some of the products I review come with a fan, I checked some sound level meters a couple of years ago, but since they were a little too expensive for my limited use, I skipped for the time being. However, while browsing some promotions or new arrivals on DealExtreme, I’ve come across UNI-T UT355 “Noise Detector Decibel Noise Tester” which sells for $15.56 including shipping. UNI-T UT353 mini sound meter specifications: Noise Levels & Accuracy – 30 to 130 dB with 0.1 dB resolution, +/- 1.5 dB accuracy Sample rate – Fast: 125ms; Slow: 1 second Measurement features – MAX/MIN, Data hold, overload indication (OL) Display – 1.64″ LCD display with backlight Buttons – Power, FAST/SLOW selection, MAX/MIN/normal selection, HOLD/BL for data hold (short press) or turning on/off the backlight (long press) Power Supply – 3x AAA batteries; 5 minutes auto power off Power Consumption – Active: < 40 […]
