Mini Review of HD23 Android Mini PC with Skype and Google Hangouts

HD23 is an Android TV box based on Allwinner H3 quad core processor that includes a 2.0MP camera and a microphone that should allow you to make and receive video calls. I’ve already taken some pictures of the device, and opened it to have a look at the hardware including the camera and microphone in HD23 unboxing and teardown post, so today I’ll specifically test the device’s camera and mic with Skype and Google Hangouts. HD23 Installation The device is made to connect to the top of your TV, so you’ll probably want to limit the weight on the back of the device, and I only connected the HDMI cable, the RF dongle for MINIX NEO A2 Lite air mouse, and the power supply cable. For the purpose of the review, I also connected a USB keyboard via the USB OTG adapter in order to take screenshots. If you wonder […]

Ugoos AM1 4K Android TV Box Unboxing and Teardown

Together with Ugoos UT4 octa-core Android mini PC, Ugoos sent me Ugoos AM1 TV box based on Amlogic S905 quad core Cortex A53 processor. There are basically two category of products with S905: entry level with 1GB RAM, and 8GB flash, which represents the majority of devices on the market, and mid range with 2GB RAM, 16 GB eMMC flash, 802.11ac WiFi and Gigabit Ethernet with devices such as MINIX NEO U1 or Tronsmart Vega S95 Telos. Ugoos AM1 is part of the second category so it will be interesting to compare its performance to the other two. But in the meantime, I’ve taken some pictures of the media player and its board to find out more about the hardware design. Ugoos AM1 Unboxing Pictures and Video All new Ugoos devices look alike, and even the retail package follows the same theme across their new devices. I got a blue […]

Unboxing and Teardown of Ugoos UT4 Android TV Box with a Cooling Fan

Most Android TV box ship with simple heatsink, which may lead to performance degradation due to throttling if you push your device a little too hard, and Ugoos UT3s was one of the few Android TV boxes to feature a fan. The company now have a new model model with Ugoos UT4 powered by Rockchip RK3368 octa-core processor, and they’ve sent me an early sample for review. Today, I’ll start by taking pictures of the device, and taking it apart to check the hardware and how cooling is implemented, before reviewed the unit in a few weeks. Ugoos UT4 specifications Before this, since I’ve only shortly mention Ugoos UT4 in Rockchip RK3368 TV boxes list, I’ll go through the specifications: SoC – Rockchip RK3368 octa core Cortex A53 processor with PowerVR G6110 GPU up to 700 MHz System Memory – 2GB DDR3 Storage – 16GB eMMC + micro SD slot […]

Review of Light Biz OS Operating System for Desktop Use (Writing a Blog Post)

This is take 2 of using an Android mini PC as a desktop PC, as I’m currently writing this post from GeekBox TV box with Rockchip’s Light Biz OS, an operating systems based on Android 5.1 with some optimizations for desktop use. I’ve already installed various productivity apps such as Gimp and Microsoft Excel, and at first this was a problem sinc Light Biz OS “internal storage” partition was too small to install some programs, so I had to resize the “userdata” partition to 6GB to make it usable. I normally blog with Firefox in Ubuntu 14.04, so right now, I’m writing with Firefox for Android, and not WordPress Android app, which would have been another option. One of the first challenge was to create links, and I could copy links with a long click providing access to copy tools in Firefox, and copy the links with Ctrl+V in Firefox. […]

Makibes F68 is a $35 IP67 Rated Sports Smartwatch with HRM & 7-Days Battery Life

So far my quest for a smartwatch as not been successful, with massive disappointments with both No.1 D3 smartwatch and SMA-Q color e-Paper smartwatch, with the latter completely failing after a week. The next potential candidate is Makibes F68 with similar features as SMA-Q, but instead with a grayscale display, IP67 ingress protection rating which should make it suitable for swimming (apparently not, see comments), as well as a promised 7-day battery life during “normal usage”. Makibes F68 specifications: MCU/Memory/Storage – Not disclosed but it’s supposed to run Nucleus RTOS. Display – 1″ round capacity touchscreen display, 128×128 resolution, always on Connectivity – Bluetooth 4.0 Sensors – 3-axis accelerometer and gyroscope Battery – 180 mAh charged via magnetic connector Dimensions – 38 x38 x 10 mm (aluminum alloy material) Weight – 31 grams IP Rating – IP67 meaning it’s been tested for 30 minutes under one meter of water.

GeekBox TV Box Unboxing and Development Kit Assembly Guide

GeekBox is both an Android TV box based on Rockchip RK3368 octa-core processor, and a Linux development kit thanks to the CPU module inside the device, a baseboard and various accessories. The company has sent me a review sample, as well as the accessories currently available. So today, I’ll have a look at the box, and show how to connect everything together. GeekBox TV Box Unboxing I’ve received two carton boxes via DHL, one with GeekBox itself, and the other with some accessories. You could use GeeBox has a TV box, and forget about its development attributes, as the device comes with the usual accessories include a case, an HDMI cable, an infrared remote control, and a 5V/2A power supply. I was really surprised by how small it was compared to other 64-bit ARM TV boxes recently launched on the market, and looks very much like a small router with […]

SimpleLink Battery-less Power Switch Leverages RF & Energy Harvesting Technologies

SimpleLink may be the name used by Texas Instruments for their wireless MCU family, but there’s also a Chinese company called SimpleLink Technology that develops wireless smart home solutions including battery-less power switches that communicate over sub GHz band to receivers using energy harvested from pressing the button(s) on the switch. They have different models with 1 to 4 buttons, and round and square shapes. Let’s have a look at SIM1010-K1 specifications: Switch Type – Push-Button; operating force: 7N; typical total travel: 4mm Number of Keys – 1 gang Power Mode: Self-Powered Control Distance – Up to 30 meters indoor (works though walls), 100+ meters outdoor Frequency Bands – 433/315/868/915MHz Lifetime – >200,000 times Connectivity – SimpleLink (most probably entirely unrelated to TI SimpleLink);  +10dBm Tx power Operating Temperature: -25~70℃ Operating Humidity: 0~95%RH Dimensions – Ф 70 x 15.5 mm Weight – 44g That self-powered wireless switch will prevent the […]

TI SimpleLink CC1310 Wireless MCU Promises 20 Km Range, 20-Year Battery Life on a Coin Cell

Some LPWAN standards such as SigFox, LoRa, or nWave allows for transmission of data at low bitrate over several kilometers, and I’ve very recently featured Microchip’s LoRa modules and motes in this blog. So when Texas Instruments sent their December 2015 newsletter entitled Wireless MCU spans 20 km on a coin cell, I decided to have a look, and the company’s CC1310 wireless Cortex-M3+M0 MCU based on a proprietary sub GHz technology also claims to last 20-year on a coin cell for applications such as grid communication infrastructure and heat and water meters. SimpleLink CC1310 key features: Microcontroller – ARM Cortex-M3 @ up to 48 MHz with up to 128KB programmable flash, 8KB DRAM for cache/general purpose, 20KB Ultralow Leakage SRAM Sensor Controller – Ultralow power and autonomous; 16-Bit Architecture; 2KB of Ultralow Leakage SRAM for code and data RF core Cortex M0 core with 4KB RAM, and ROM Data […]
