Zero Devices Z5C Thinko 4K H.265 TV Stick Review

Zero Devices Z5C Think is one of the rare HDMI TV sitck powered by Rockchip RK3288 quad core Cortex A12/A17 processor available on the market. I’ve already take a few pictures of the device and internals, so today I’ll focus on testing the firmware, and performance of this thin and nice looking TV stick. First Boot, Settings and First Impressions There was a time when HDMI stick were powered by much slower, but power efficient processor based on Cortex A5 cores. One of these was CX-01 mini PC, and they could be powered by the USB port of the TV without problems. Now the processor are much more powerful, so normally you can’t power the device directly from the TV, but since I’ve seen people claim it was possible to drive RK3288 stick directly from the USB port of some TVs, I gave it a try, connected the stick to […]

AllWinner A80 Octa Core big.LITTLE Processor CPU Usage Under Various Loads in Android 4.4 (Video)

Allwinner A80 is one of the few octa core processors featuring ARM’s big.LITTLE technology currently available on the market. The processor comes with four ARM Cortex A15 (big) cores, and four ARM Cortex A7 (LITTLE) core, and tasks will be scheduled to different processor depending on the load to optimize power consumption on mobile devices. However, earlier big.LITTLE processors like Samsung Exynos 5410 has some serious limitations, as they only supported “cluster migration” meaning you could only use the Cortex A7 cluster or Cortex A15 cluster at any given time, so Exynos 5410 could only make use of four cores at most due to hardware limitations. They also used to be two software implementations: In-kernel Switching (IKS) and Global Task Scheduling (GTS). The former could only handle one type of core at the same, and the latter, which I believe is now used in all new devices, can handle any […]

MINIX NEO X6 Media Hub Review

Last week-end, I took a few pictures of MINIX NEO X6 media hub, and had a look at the company’s firmware and forum support which indeed seems to be good. Today, I’ve completed the full review of MINIX NEO X6, and I will compare it to two of its lower priced competitors: MXQ S85 and EM6Q-MXQ. First Boot, Settings and First Impressions The IR remote control works fine, including continuous up ad down pressing, but I switched to using Mele F10 Deluxe air mouse for convenience. I’ve connected an Ethernet cable, an HDMI cable, a micro SD card, a USB hard drive, and a USB hub with two RF dongles for my air mouse and gamepad, a USB flash drive, and a UVC webcam. I’ve connected the power, pressed the power button on the side of the box, but nothing happened at first… You have to press the button one […]

Tronsmart Draco AW80 Octa core Android TV Box Review

Tronsmart Draco AW80 (click for full specs) is the first octa core Android TV box / mini PC thanks to Allwinner A80 processor. Draco AW80 Meta model comes with 2GB RAM / 16GB eMMC, and the upcoming Draco AW80 Telos will feature 4GB RAM and a 32GB eMMC. Geekbuying sent me the Meta version for review, and since I’ve already posted pictures of the device and board, today I’ll post my findings after testing the unit. First Boot, Settings and First Impressions I’ve inserted two AAA batteries in the provided remote control, and it works as expect, but as usual, I’ve used Mele F10 Deluxe air mouse to control the device during my testing, since it’s impossible to use most apps with an IR remote control, XBMC/Kodi being one exception. I’ve connected an HDMI cable, a USB 3.0 hard drive to the USB 3.0 OTG port of the TV box, […]

$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]

Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this […]
