Android 4.1 vs Android 5.0 Performance Comparison

Most of the time people compare the performance of different hardware platforms, but since Wandboard released an Android 5.0 image in the last few days, I wondered what difference two years of software development may make by comparing benchmark results. So I ran both Antutu 5.6.1 and Vellamo 3.1 on Android 4.1.2 Jelly Bean (android-4.1.2-wand-dual-20130411.zip) and the latest Android 5.0 Lollipop firmware for Wandboard Dual (Freescale i.MX6 Dual) development board. Android 4.1.2 Benchmark Results Antutu 5.6.1 Vellamo 3.1 You’ll notice the yellow triangle on the top right corner of the multicore and browser results due to some warning related to missing CPU frequency information, and a DOM timeout. Android 5.0 Benchmark Results Antutu 5.6.1 The 2D graphics looked weird at some point as it zoomed out on1/4 of the display. The screenshot did not show the total score, so I added it manually to the picture above. Vellamo 3.1 Vellamo […]

Freetronics Introduces an Arduino Shield for ESP8266 ESP-01 Wi-Fi Module

ESP8622 has drastically brought down the price of adding Wi-Fi to MCU boards such as Arduino UNO,  but you need to add some cables, and take care of 3.3V to 5V conversion for the UART pins either with a divider made of 2 resistors, or a FET level shifter, and you may not be able to access all I/O of ESP8622 on the popular ESP-01 version of the module. For a neater solution, Freetronics had designed ESP-01 WiFi Module Shield that takes care of all these small issues. Key features of the shield: 3.3V regulator dedicated to the module Logic level shifters on TX/RX lines: compatible with both 3.3V and 5V Arduino models Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 – D7 for software serial CH_PD pin on ESP-01 module pre-biased for correct operation mode Extra ESP-01 pins broken out for your own connections Prototyping area with […]

Voltera V-One is a Low Cost PCB Printer and Solder Paste Dispenser (Crowdfunding)

The traditional hardware development cycle involve sending PCB Gerber files to a manufacturer, wait a few days (or weeks), get the boards back, find and fix bugs, send a new revision of the gerber files to the manufacturer and so on. This wastes a lot of time, so PCB printers capable of handline single and dual layer PCBs have started to see the light of the day, for example with BotFactory Squink. The latter can also do pick and place, but costs over $3,500. Luckily if you’d like something cheaper, Voltera V-One will do many of the same tasks, for but for only $1,500. Voltera V-One specifications: Minimum Trace Width – 8mil (~0.2mm) Minimum Passive Size – 0603 (0402 for solder paste) Minimum Pin-to-Pin Pitch – 0.8mm (0.5mm for solder paste) Resistance – >12 mOhm/sq @ 70um height Max Heated Bed Temperature – 250C Heated Bed Ramp Rate – ~2C/s […]

Power Consumption of Amlogic S812 and Rockchip RK3288 TV Boxes

The recent post comparing the power consumption of ODROID-C1 vs Raspberry Pi boards, as made me want to give another try at power consumption measurements. Regular reader already know I made a power measurement board and cables capable of hading different connectors (micro USB, mini USB, power barrels,  etc..), but eventually it failed to deliver enough current to the boards for any meaning testing. But since I now have a better power supply, and multi-meter, it was worth another try, especially since I could draw some pretty charts. I decided to test the three most popular Chinese SoCs for mini PCs namely Amlogic S812 (4x Cortex A9), Rockchip RK3288 (4x Cortex A17), and Allwinner A80 (4x Cortex A15 + 4x Cortex A7) using respectively Eny M8S, Open Hour Chameleon, and A80 OptimusBoard. If you are paying attention, you must have noticed Allwinner A80 is not part of the title, that […]

Egreat A9 Quad Core Android Media Player Comes with HDMI Input, a 3.5″ SATA Bay

Egreat A9 was first shown in spring last year with a Realtek RTD1195 processor, but it’s only now that I could see it for sale. But just like Zidoo X9, the device is now powered by Mstar MSO9810 quad core processor, and features an HDMI input port with PVR capabilities, but adds an internal 3.5″ SATA bay, double the internal storage (16GB eMMC), as well as a Gigabit Ethernet port. Egreat A9 specifications: SoC – Mstar MSO9180-DB2 quad core Cortex A9 processor up to 1.5GHz with an ARM Mali-450MP GPU System Memory – 2GB DDR3 Storage – 16 GB eMMC flash + 3.5″ internal SATA bay Video Output / Input –  HDMI 1.4b output up to 4K30, HDMI input (1080p) with PVR support Audio I/O – HDMI Out and In, and optical S/PDIF Video Containers & Codecs DAT, MPEG, MPE, MPG, TS, TP, VOB, ISO, AVI, MP4, MOV, 3GP, FLV, […]

Review of Zidoo X9 Android Media Player and Video Recorder

Zidoo X9 is quite a unique product on the market, as it’s the only low cost Android platform that I know of that features an HDMI input port with recording capabilities. The hardware is actually based on Kaiboer F5, with some modifications, but the latter focuses on the Chinese market, while Zidoo X9 targets oversea markets with an English firmware by default. I took pictures of Zidoo X9 and its board about a month ago, but a busy schedule and some initial issues with Google Play Store delayed the review. Finally, I’ve completed testing of the device, and ready to share my findings about performance, stability, and features in this review. OTA Firmware Update I’ve had to go through two firmware updates before carrying on with the review, and this part is working great, and they even include a detailed changelog with each release, which they also publish on their […]

Linux 3.19 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 3.19 yesterday: So nothing all that exciting happened, and while I was tempted a couple of times to do an rc8, there really wasn’t any reason for it. Just as an example, Sasha Levin used KASan and found an interesting bug in paravirtualized spinlocks, but realistically it’s been around forever, and it’s not even clear that it can really ever trigger in practice. We’ll get it fixed, and mark it for stable, and tempting as it was, it wasn’t really a reason to delay 3.19. And the actual fixes that went in (see appended shortlog) were all fairly small, with the exception of some medium-sized infiniband changes that were all reverting code that just wasn’t ready. So it’s out there – go and get it. And as a result, the merge window for 3.20 is obviously also now open. Linus Linux 3.18 improved performance of […]

Raspberry Pi Model B+ Can Now Be Purchased for About $30 Shipped

The Raspberry Pi maybe promoted as a $35 ARM Linux board, but in reality once you had taxes and shipping the price can be quite higher. For example on Element14 Thailand, I would have to spend 1,300 Baht ($40) + shipping,  or even 1750 Baht ($54) to get the board. But since Raspberry Pi 2 launch, sales numbers for R-Pi model B+ have most likely dwindled, and some sellers are trying to get rid off stock. Some deals I have found or been tipped off: $30.29 on Amazon US. Free shipping in the US on orders over $35. $31 including shipping on Aliexpress $33.99 including shipping on Bangood $37.81 including shipping on DealExtreme $37.88 including shipping on Ebay If you know of other better or similar deal for the Raspberry Pi Model B/B+, feel free to leave a link in comments. Thanks to Onebir for the tip.
