Checking Fan Noise and Other Sound Levels with Benetech GM1352 Sound Level Meter

I wrote about UNI-T UT353 Sound Level Meter a few month 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, but I did not really use so far, since I did not get a new device with fan. I’ve now had the chance to try it as Voyo VMac Mini 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 – Power/Backlight, MAX/MIN/Normal selection, HOLD Power Supply – 3x AAA batteries (included) Dimensions – 15.7 cm x […]

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 […]

Magic Device Tool Helps You Switch Between Android and Ubuntu on Supported Phones

There have only been a few phones released with or supporting Ubuntu so far, and those phones will normally be able to run Android too since Ubuntu Touch relies on Android drivers, and you may decide that Ubuntu is not for you and switch back to Android, or the contrary, if you’ve purchased an Android phone, you may want to install Ubuntu instead. In order to simplify the task of installing operating systems, Marius Quabeck has developed “Magic Device Tool“. As you can see from the screenshot above, 13 phones and tablets are currently supported. You’ll need a computer with Ubuntu 15.04 or greater to install the tool, and I’ve done so on Ubuntu 16.04:

The script will also install phablet-tools if it is not already installed,  so if you are not root, you’ll need your account to be member of sudoers. Once the initial setup is done, you’ll […]

DVB Channel Editor Tools for K1 Plus T2 S2 Android TV Box

K1 Plus T2/S2 is one of the most popular Android TV boxes with digital tuners, including both DVB-T2/T/C and DVB-S2/S tuners, and I get frequent comments and questions on K1 Plus T2 S2 review. One of the often asked request is a channel editor to use on a computer, in order to change the names, the order of channels, and set favorites. You can export the DVB data from the DTV app in Android with all data stored in dtv_user_data directory, and in theory, one web based editor is supposed to let you do just that, but it did not work for me. Another option shared with us by gabywap is K1_Plus_Editor.exe (Mirror) developed by Sm0ke, who appears to mostly frequent Russian forums. So I downloaded it, and launched it with Wine in Ubuntu 16.04, but the channel data I had could not load, and the program showed some error […]
