Review of Measy U2C Rockchip RK3066 Mini PC With Built-in Camera

I’ve received 2 new devices to play with this week, as Geekbuying sent me Tronsmart Promotheus set-top box and Measy U2C, a mini PC with a webcam, so that I can test and review them. Today, I’ll leave the “Spaceship” set-top box parked in another galaxy, and I will review Measy U2C mini PC. This HDMI dongle is powered by Rockchip RK3066, runs Android 4.1.1, and comes with 1 GB RAM, 8GB Flash, Wi-Fi & Bluetooth connectivity, and a built-in 2MP Webcam. For complete specs, you can check my post about B12 mini PC since this device uses the same board internally. Geekbuying sells this all-in-one mini PC for $74.99 including shipping. As usual, I’ll post some unboxing pictures, and then review the device, this time, with a section dedicated to the webcam, since this is the key selling point of this mini PC.

Quake 3 Arena Demo Using Lima Driver is (Slightly) Faster than Mali-400 Binary Driver

As mentioned previously, Luc Verhaegen was to give a talk about the status of Lima driver (reverse-engineered Mali-200/400 GPU driver), as well as other GPU open source implementation, at FOSDEM 2013. This is now done, and part of the talk included a demo of Quake 3 Arena (q3a timedemo) running on tablet featuring AllWinner A10 SoC (Cortex A8 @ 1Ghz, Mali-400MP1 GPU @ 320 Mhz, and DDR3 memory @ 360MHz), and a 1024×600 LCD. The fact it works is already a great achievement in itself, but this demo runs at 47.2fps with Lima driver (limare), whereas it can be rendered at 46.2fps using the binary driver. In his blog, Luc also explains that apart from being 2% faster, it also uses 3% less cpu than the binary driver! Take that binary blobs! There’s still more work to do however, as this Quake 3 Arena port is not playable yet for 2 […]

U-boot, Linux Kernel, and Android Patches for Freescale i.MX6 HDMI TV Dongles

We can now get some quad core Android mini PCs (e.g. Hi802, GK802) featuring Freescale i.MX6Q processor, Freescale has released full documentation and source code its development platforms, Hi802 / GK802 HDMI TV dongles are easily hackable, and there’s even an Ubuntu image for the devices. So it looks pretty good ,right? Well almost.. there are some patches and config for GK802 that have not been released by Richtechie, so we can’t modify the  bootloader and Linux kernel. But this may change, as ARMTvTech forum user hste noticed some Freescale i.MX6 HDMI dongle patches om IMX Community website. Even though I’m not sure those are fully compatible with Hi802 / GK802, this could be a starting point. Today, I’ll provide the instructions to build u-boot, the linux kernel and Android ICS with those patches in a machine running Linux 12.04 64-bit. Patch Sets Descriptions There are two set of patches that […]

Atmel Introduces SAMA5D3 Cortex A5 Embedded MPUs and Evaluation Kits

Atmel has recently announced the Atmel SAMA5D3 series, a family of high performance, low-power microprocessor units (MPUs) based on ARM Cortex-A5 core. The SAMA5D3 series is designed for embedded applications in the industrial space, including factory and building automation, smart grid, medical and handheld terminals, as well as consumer applications such as smart watches, outdoor GPS, and DECT phones. SAMA5D3 family has the following characteristics: ARM Cortex-A5 core up to 536MHz (850DMIPS). Floating point unit (FPU) with up to 3 times the performance of Cortex A8 FPU. 166MHz bus speed delivering up to 1328MB/s bandwidth. Power consumption: <200mW in active mode at 536MHz with all peripherals activated 0.5mW in low-power mode with SRAM, registers retention and <0.5ms wake-up time ~1.2µA in backup mode with RTC running Connectivity: Dual Ethernet and dual CAN ports (Only one model has both) Gigabit Ethernet MAC with IEEE1588 and 10/100 MAC Two CAN controllers 3x […]

Raspberry Pi Model A is Now Available (But Only in Europe)

The Raspberry Pi has just announced that RS Components and Premier Farnell/element14 have now Raspberry Pi Model A boards in stock. Raspberry Pi Model A is a cost down version of Model B using the exact same PCB but with less RAM (256 MB vs 512 MB), no Ethernet, and only one USB port. This model seems more suitable for embedded projects, and you can get connectivity via Ethernet, Wi-Fi, 3G… USB dongles. It consumes about a third of the power of the Model B, which will certain help with projects powered by solar panels or batteries. It could also be suitable as an even cheaper XBMC player, but if you need to add a USB Hub to connect extra peripherals, it may not really be worth it. Model A is only be available in Europe for now, but will eventually be available worldwide. It will cost UK customers 26.02 […]

How To Root Droid Stick A2 mini PC

Droid Stick A2 mini PC does not come rooted, so here’s a simple rooting guide for the device. First, make sure you’ve installed the latest firmware, then follow the instructions below (Source: ARMTvTech): Copy update_Superuser.zip to the root of a micro SD card. Insert the microSD card to Droid Stick A2, and power the device Go the Apps menu in Android, and launch “Upgrade” app. Select Local Upgrade Select update_Superuser.zip Select Reboot And Install Package Let the update go through, and let it boot to Android. You should now have root access. This method deleted old version of su and Superuser.apk, copies su to /system/bin & Superuser.apk to /system/app, and changes permissions on those files. It may also work on other AMLogic AML8726-M1 / M3 / MX based devices. If you are interested in knowing exactly what it does, unzip update_Superuser.zip, and open /META-INF/com/google/android/updater-script. For some reasons, the first time I […]

Crazyflie Nano Quadcopter Open Source Development Kit

If you can’t wait until 2014 to get the MeCam, Seeedstudio has something for you: The Crazyflie Nano Quadcopter, which looks similar to the MeCam, but does not feature a camera, its control board is powered by STM32F103CB MCU @ 72 MHz with 128kb flash and 20kb RAM (so, no it won’t run Linux), and at $173 the price is significantly higher. Here are Crazyflie key features: Small and lightweight, around 19g and about 90mm motor to motor Flight time up to 7 minutes with standard 170mAh Li-Po battery Standard micro-USB connector for charging which takes ~20min for the stock 170mAh Li-Po battery On-board low-energy radio@1mW based on the nRF24L01+ chip. Up to 80m range (environment dependent) when using the Crazyradio 2.4 GHz USB dongle Radio bootloader which enabled wireless update of the firmware 32 bit Cortex M3 MCU: STM32F103CB @ 72 MHz (128kb flash, 20kb RAM) 3-axis high-performance MEMs […]
