发表于 经过vip亚博 -10 Commentson Review of Allo Vana Player Linux HiFi Audio System with Max2Play, SqueezeBox and Kodi

使用Max2play，Squeezebox和Kodi的Allo Vana Player Linux Hifi音频系统的评论

Last month I showcased what I called “Allo Sparky Audio Kit” with a DAC board (Piano), an amplifier board (Volt), and usually hard to find reclocker and capacitance multiplier boards (Kali & CM), all connected to Allo Sparky ARM Linux development board powered by Actions Semi S500 quad core Cortex A9 processor, and running Ubuntu 12.04. In the first post, I just described the boards, and showed how to assemble the kit, but now that I have received the user’s manual, it turns out the kit is actually called “Vana Player” and the provided Ubuntu firmware image runs Max2Play Browser based system that’s also available for Raspberry Pi and ODROID boards. Before starting the kit, you’ll need to connect speakers to Piano DAC board and/or Kali board, as well as a 19.5V power source such as a laptop power supply to connect to the CM board. I connected some USB […]

$ 16及以上RGB LED蓝牙4.0灯泡包括扬声器

I’ve just stumbled upon “H1007 Smart E27 Bulb Bluetooth 4.0 Speaker” on GeekBuying. It’s a smart Bluetooth 4.0 RGB LED E27 light bulb that also include a speaker, and sells for $22.59 shipped. I find it’s a good idea, and after looking for other models, I’ve found the $99 Twist light, as well as a much cheaper “OY-QP-BM13” model on eBay going for $15.99. I’ll look at (HZ-)H1007 specifications first: Light Bulb 5W; adjustable RGBW; 330 Lumens; Color temp: 6500K Screw Type – E27/E26 Connectivity – Bluetooth 4.0 LE up to 20 meters range Audio – 3W amplifier; 3D surround audio Voltage – 100 to 240V 50/60Hz Dimensions – 72 mm diameter x 136 mm length Weight – 146 grams The body of the light bulb is available in white, red, golden, and blue, and it ships with a user’s manual in English and Chinese. I could not find the […]

Kodi 17 Amlogic S912电视盒中的设置和音频/视频支持（截至2016年9月）

截至今天，大多数安装Kodi的人都将选择Kodi 16.1，因为它是最新的稳定版本。但是我目前正在审查基于Amlogic S912八核处理器的Qintaix Q912电视盒，其Android 6.0固件包括Kodi 17 Alpha 3，因此，由于这是我第一次运行Kodi 17“ kingpton”。我决定通过测试一些4K视频和音频文件来报告有关界面的经验以及有关音频和视频亚博体育官下载支持的当前状态。我将最新的可用固件用于测试。可以在主发射器上找到Kodi 17，对于第一次发射，我们将看到默认的皮肤已从汇合处替换为新的河口皮肤。第一个令人困惑。我们可以通过进入左下方的图标，在电源按钮的右侧，然后选择[…]，然后选择“设置”菜单。

Widora-Neo OpenWRT WiFi IoT＆Audio Board基于Mediatek MT7688 SOC，WM8960音频DAC

A couple of weeks ago, I reviewed ReSpeaker board combining MediaTek MT7688 WiFi SoC with WM8960 audio DAC, running OpenWrt, and allowing you to perform tasks using text-to-speech and speech-to-text thanks to the built-in microphone (or optional microphone array), and a 3.5mm audio jack to connect speakers, as well as several I/O pins. It turns out there’s been board with similar features, minus the built-in microphone, available in China for a while. Meet Widora-NEO. Widora-NEO board specifications: SoC – Mediatek MT7688AN MIPS SoC @ 580 MHz with built-in WiFi System Memory – 128 MB RAM Storage – 16MB SPI flash, micro SD card Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi 1T1R up to 150 Mbps with PCB antenna, or IPEX connector Audio – 3.5mm jack for stereo headphone and mono microphone, WM8960G audio codec USB – 1x micro USB port for programming via CP2104 chip, 1x micro USB host (or […]

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 […]

Allo Sparky Audio套件将ARM Linux板与放大器，音频DAC，Reclocker和电容乘数板相结合

Last year I wrote about Allo Sparky SBC Linux and Android development powered by Actions Semi S500 quad core Cortex A9 processor, which mostly differentiates itself from the competition by the many add-on boards for audio, VoIP, and IoT (WiFi+Bluetooth+Zigbee ). While most of development boards are manufactured in China, Allo company is based in India, and all boards are manufactured there, which could be a benefit to Indian readers who want to avoid potential custom issues with other boards. The company has shipped me their complete audio development kit, and I’ll first check out the hardware, before taking time to experiment with the kit in a few weeks or months… I could find 6 different boards in the kit, which I detailed below, as well as a 5V/3A power supply with AU and EU adapter, a micro USB adapter, a micro SD card apparently pre-loaded with Ubuntu 12.04, a […]
