Cubieboard4 Benchmarks in Android

Last time I tried running benchmarks in an Allwinner A80 board (A80 OptimusBoard), it either rebooted during the benchmark, or had fairly disappointing results for example for USB storage. I documented my findings in a post entitled “Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board” which was written in October 2014. But a few months have passed, and since Cubieboard4 is another hardware platform, so I was interested in running benchmarks including storage and networking performance testing on the new board to see if any progress was made. Cubieboard4 Android Benchmarks – Antutu, Vellamo, and 3DMarks Manufacturers can add the key ro.sys.hiritsu to build.prop in order to artificially inflate their Antutu scores with Allwinner A80 processor. So before running Antutu, I checked /system/build.prop in the firmware, and found out no trace of this variable, which can only be good for CubieTech reputation. CC-A80 board, the other name […]

Zsun Wifi Card Reader Adds up to 64GB to Your Smartphone

I’ve previously covered Zsun SD11x USB flash drives with 8 to 128 GB internal flash, a battery, and Wi-Fi connectivity in order to easily add storage to devices without micro SD slots. The company has now launched a new Wi-Fi card reader to do the same, but with your own micro SD card instead allowing up to 64GB extra storage, and easy replacement. Zsun card reader specifications: SoC – Qualcomm Atheros AR9331 WiSoC System Memory – 256 Mbit RAM (32 MB) Storage – Internal flash for firmware (capacity TBD), micro SD slot up to 64GB Connectivity – 802.11 b/g/n Wi-Fi @ 150 Mbps USB – 1x USB 2.0 port for power and use as standard USB card reader Dimensions – 33 x 30 x 13 mm There’s no battery, so you’d have to connect the dongle to a power bank, PC, car charger etc.. to power it. If you connect […]

Zsun SD111 Is Now “Officially” an Hackable Wireless Flash Drive

Zsun SD11x are Wi-Fi flash drives for 8 to 128 GB eMMC, alternative to Sandisk or Kingston. Yesterday, I soldered the UART pins to Zsun SD111 (8GB) flash drive to access the serial console, but I did not manage to enter the terminal as it was password-protected. I posted my results anyway, as I was convinced I would get some clever ideas from my readers, some of which appeared to be a little time consuming, but Zoobab offered a simple solution that consisted in changing the boot parameters, by replacing /sbin/init by /bin/sh. The first step is to interrupt the boot by pressing space or another key, in order to access U-boot. Now we can check the U-boot environment ar7240> printenv bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 rw init=/sbin/init mtdparts=ar7240-nor0:64k(u-boot),64k(u-boot-env),6720k(rootfs),1216k(uImage),64k(NVRAM),64k(ART) bootcmd=bootm 0x9f6B0000 bootdelay=4 baudrate=115200 ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee ipaddr=10.168.168.1 serverip=10.168.168.10 stdin=serial stdout=serial stderr=serial ethact=eth0 Environment size: 361/65532 bytes Let’s keep everything the same, except the init, […]

Zsun SD111 Wireless USB Flash Drive Review

Zsun SD111, SD112 and SD113 are Wi-Fi / USB flash drives with respectively 8GB, 16 GB and 32GB storage. GearBest sent me the 8GB version (SD111) for review, as it could be an interesting platform to hack. I’ve take picture of the device, take it apart to check the board, review quickly the standard features with Android and Ubuntu, and try to access the board from the network. Zsun SD111 Unboxing I received the device in the following package. The flash drive comes with a micro USB to USB cable for charging and accessing the device from a computer, and a user’s manual in Chinese. You’ll probably prefer using a soft copy user manual in English… Zsun SD111 Board and Battery To open the stick, insert a sharp and thin object in the hole for the neck strap, and push upwards to lift the top cover a little, and finish […]

ZSun Wireless USB Flash Drives Add up to 32GB to Your Mobile Device

Yesterday, I wrote about the Egg personal cloud storage device which allows you to easily store and share your files without having to rely on cloud services, and also includes a touchscreen display. But it might be possible to achieve the main selling point of that product, that is keeping your data private, while accessing it from anywhere, at a fraction of the cost, by using a Wireless USB flash drive instead. Some well known companies such as Kingston (rather expensive), and Sandisk (much more affordable) already offer such products, but I’ve been informed Zsun, a Chinese company, was also manufacturing such devices with up to 32 GB capacity. The company calls its wireless flash drive “Apple Disks” showing how much money you could save with their device, by showing the ridiculous price different between apple devices with difference storage capacity, but they can also work with Android devices, as […]

USB Type-C Reversible Connectors Specifications Published

We now have all sorts of USB receptacles and connectors, but this is supposed to eventually change thanks to type-C connectors, which are small and robust enough to be used in laptop, computer, smartphones, and other type of devices, and will replace the USB type A, micro and mini USB ports. Type-C connectors will also be reversible, so there won’t be a way to insert the cable upside down. The USB 3.0 Promoter Group has just announced the completion of the USB Type-C specification, and transferred it to the USB Implementers Forum (USB-IF) for ongoing management and the establishment of a compliance and certification program. Key features of Type C specifications include: Entirely new design Tailored for emerging product designs Robust enough for laptops and tablets; slim enough for mobile phones Similar to size of USB 2.0 Micro-B Usability enhancements – Reversible plug orientation and cable direction Supports scalable power charging […]

iFans EL-PB-17 is a 3-in-1 USB Wall Charger with a Battery and an SD Card Slot

I’ve noticed TYLT ENERGY 2K a USB wall charger with an internal 2,300 mAh battery, is currently on Kickstarter for $20, and received some press coverage. The main advantages of this system is that it saves space ,and you don’t need to remember charging your phone and your USB power bank separately, it will just charge both within 3 to 4 hours. However, since I’ve recently purchased a USB solar power bank with a 30,000 mAh battery (actual 8,000 to 10,000 mAh) for about $25, I thought there must be better options with a larger batter and similar price, or cheaper price with a similar battery size. It turns out there aren’t so many options, but I did find NewTrent Travelpak Plus with a 7,000 mAH battery that sells for about $40 on Amazon and even $19 on Ebay. But I’ve found a product even more original and versatile with […]

USB 3.0 Connectors and Receptacles Explained

The other day, I opened one of the products I received for review, and I found a blue connector on the board with no description. USB 3.0 connectors are blue this connection seemed “funny” with two internal connectors, and I though it must have been something else, and asked on Google+. It turned out this is a USB 3.0 Standard-B receptacle. As my knowledge about USB 3.0 connectors was obviously lacking, I’ve decided to investigate and have a look at the different existing and upcoming USB 3.0 connectors that we should find in different types of devices and computers now or very soon. Standard-A USB 3.0 connectors and receptacles This is the easy one, it looks very similar to the USB 2.0 connectors, except it’s blue and adds 5 pins for USB 3.0 connectivity. It’s backward compatible with USB 2.0, and the receptacle is used for hosts. Most people must have […]
