List of Chinese Online Stores and Shopping Guide

Most of the time I feature products that are sold on Chinese online stores, because it’s either the only way, or the cheaper way to purchase the products. However, it’s not always easy to decide which Chinese e-retailer to select, and to avoid potential pitfalls with the sellers, and/or at home when you receive the products and get charged all sort of taxes. In this post, I’ll go through a list of Chinese online stores, the ones I personally use, and others, and then provide a guide with a series of tips and recommendations to hopefully help you shop with minimal worries. I’ll only cover retail stores, and skip wholesale sites such as Alibaba. Two types of stores Before I get the list of stores, it’s important to consider there are two types of stores: E-retailers (B2C) –  In this case, you buy directly from the retailer which collects payment, […]

Dimple NFC Sticker Adds Four Hardware Buttons to Your Android Device (Crowdfunding)

If you’d like to add one button to your Android smartphone, you could use pressy. But what if you wanted or needed more. Dimple may provide a solution if your Android smartphone or tablet supports NFC. It is a thin NFC sticker, about 0.5mm thick, that you can attach to the back of your device to add 4 hardware buttons. The sticker is compatible with devices running Android 4.0 and above, not made out of metal, and with NFC support. This means HTC One M7 and M8 smartphone are not compatible due to their metallic bodies. Using the NFC sticker appears to be extra simple. Once you’ve sticked your Dimple to the back of your device (or your case), simply install Dimple.io app to configure the buttons to do what you want to: launch your favorite apps, take a picture, turn on & off the flash light, call your mum, […]

AMD Unveils Low Power Mobile “Mullins” APUs for Tablets and Hybrid Laptops

AMD has announced its 3rd-generation Mainstream and Low Power Mobile Accelerated Processing Units (APUs), codenamed codenamed “Beema” and “Mullins,” respectively, featuring four x86 Puma+ CPU, AMD Radeon graphics, and a platform security processor (PSP) with an ARM Cortex-A5 core for ARM TrustZone  security. Beema APUs have a TDP between 9W and 15W, whereas Mullins APUs all have less than 5W TDP (2.8W SDP). So I’ll only cover cover Mullins processors in this post, as they may offer an alternative to Intel Bay Trail-T processors. There are now 3 more APUs part of AMD’s tablets and 2-in-1 solutions: A10 Micro-6700T, A4 Micro-6400T, and E1 Micro-6200T. They are highlighted in green in  the table below, and compared to previous generations: Model​​ Radeon Brand CPU Clock Speed (Max/Base) CPU Cores on Die TDP Total L2 Cache GPU Clock Speed (Max/Base) DDR SDRMA Max Memory Speed ​A10 Micro–​​6700T ​Radeon R6 ​2.2 GHz ​4 ​4.5W ​2MB […]

Kankun KK-SP3 is a $20 Wi-Fi Smart Socket for Android and iOS

I’ve already featured Broadlink SP1 and SP2 smart socket on this blog.  The former is a simple Wi-Fi smart socket for Android and iOS, and the later adds support for motion sensing and energy monitoring.  They cost respectively about $30 and $45 including shipping. I’ve discovered another cheaper option with Kankun KK-SP3 via DealExtreme ($23.75), but it can also be found on Aliexpress for as low as $19.99 including shipping. If you live in China, It’s available on Taobao for 99 RMB ($15.82). Here are the specs of this smart socket: Power Plug – Three flat-pin plug (Australia type) Wi-Fi – 802.11 b/g/n, 15 dbm. Texas Instruments Wi-Fi module (CC3000?) Input Voltage – 90~265V @ 50-60 Hz Output Current – 10A Maximum Power – 2200W Dimensions – 5.3 cm x 5.3 cm x 2.8 cm Temperature Range – -10 to 55°C Unless you live in Australia, China, Argentina, New Zealand, […]

HOWCHIP 5420-DVK is a Mobile Development Kit with Samsung Exynos 5420 SoC, an OLED Display

With Arndale Octa already shipping, and the upcoming ODROID-XU2, we already have two low cost boards with Samsung Exynos 5420 big.LITTLE processor for less than $200. But if you want a more complete kit, HOWCHIP 5420-DVK with a 4.65″ OLED display and capacitive touchscreen, 2GB RAM, 4GB eMMC, and various connectors, could be an option. There’s also a Lite version without the OLED display. The board is composed of a CPU module, a baseboard, and a phone like display. Here are the specifications: SoC – Samsung Exynos 5420 Octa with 4x ARM Cortex A15, and 4x ARM Cortex A7 in big.LITTLE configuration, with Mali-T628 GPU.

Samsung Galaxy K Zoom Camera Phone Powered by Exynos 5 Hexa SoC

After Samsung Galaxy S4 Zoom, Samsung has just introduced a new camera-specialized phone called the Galaxy K Zoom with a faster processor, an hexa core processor, which has not been named, but can only be Exynos 5260 hexa core big.LITTLE SoC, a larger 4.8″ display, and a better camera with a 20.7 Megapixel CMOS Sensor and a 10x Optical Zoom. Let’s go straight through the specifications: SoC – Samsung Exynos 5260 Hexa core processor with four Cortex A7 cores @ 1.3GHz,  two Cortex A15 cores @ 1.7GHz, and ARM Mali-T624 GPU System Memory – 2GB RAM Storage – 8GB Flash + micro SD slot up to 64GB Display –  4.8″ HD Super AMOLED Display (1280×720) Cellular Network LTE – Cat4, HSPA+ 42Mbps, LTE 800/850/900/1800/2100/2600, HSPA+ 850/900/1900/2100, EDGE/GPRS 850/900/1800/1900 3G – 5-band HSPA+ 42Mbps, HSPA+ 850/900/1900/2100,EDGE/GPRS 850/900/1800/1900 Connectivity – Wi-Fi: 802.11 a/b/g/n 2.4+5GHz, Bluetooth 4.0 BLE, NFC, A-GPS + GLONASS  Camera […]

$15 AsiaRF AWM002 & AWM003 Wi-Fi Modules Run OpenWRT, Expose GPIOs

This week-end I explained how to build a web server that could be used for automation and other Internet of things applications for less than $15 by combining an Arduino Leonardo with ECN18J60 Ethernet module. The hardware itself is cheap, but it may not always be convenient, or cost effective, to wire your house or office with Ethernet cables. One solution is to use Wi-Fi modules such as TI CC3000 evaluation module, an Electric Imp module, or Ariettea G25 + Wi-Fi board, but these usually cost between $30 to $50 in single quantity. AsiaRF AWM002 and AWM003 are low cost 802.11n Wi-Fi modules with access to GPIOs that could be an interesting alternative as they cost $15 + shipping, and even below $10 in quantities. The only difference between the two is that AWM003 supports more RAM (64MB vs 32MB). Here are the specifications for these modules: SoC – Mediatek/Ralink […]
