AAduino Arduino Compatible Board Fits Neatly into an AA Battery Holder

Johan Kanflo has been using Arduino compatible boards based on Tiny328 MCU with an ISM radio module (wireless Arduino clone), but he found that finding a case was not easy, and was quite not ready to to design its own and print it with a 3D printer. So instead he shrank the board to fit into an AA battery case bought on Ebay with two AA batteries taking the remaining slots. That’s the result. AAduino board specifications: MCU – Atmel ATMega328p clocked at 8 MHz to save power Radio – RFM69C ISM transceiver module Sensors – Two DS18B20 temperature sensors Misc – Indicator LED Keystone battery terminals rotated 180° to act as positive and negative terminals. Power – 2x AA batteries The project is also open source hardware, with all hardware files released under the MIT license on Github, where you’ll also find a demo sketch for the board. Via […]

Mini Review of NextDrive Plug for Private Cloud Storage and Home Security

NextDrive Plug is an ARM based plug computer that’s used to store your photos or music, and/or as a security system using a webcam combined with Pixi motion sensor. They had a successful crowdfunding campaign, and now that they’ve sent rewards to backers, I’ve also received NextDrive Plug and Pixi for evaluation. The courier was not particularly gentle with the packages, but the devices themselves were not damaged. NextDrive Plus package included the box, a US plug, and a user’s manual in English. Pixi comes with two 3M stickers, and a user’s manual. There’s also a plastic film to avoid depleting the battery, that you’ll need to remove before using the sensor. The interfaces on the plug are minimal with a USB port for a USB mass storage device (HDD, flash drive…) and/or a UVC webcam, and the socket for the power plug adapter on the back.You can then plug […]

HDMI Audio in Linux is Now Working on Cherry Trail mini PCs, OpenELEC 7.0 Image Released

Since Intel has decided not to officially support Bay Trail and Cherry Trail processors in Linux, and focus on other priorities, people who have tried to use HDMI audio in Linux with mini PCs or TV sticks based on the processors have always had issues. There’s a workaround for Bay Trail mini PCs with Linux 3.16 kernel, but so far I’ve never seen a Cherry Trail system working with HDMI audio in Linux. Luckily, Pierre-Louis Bossart has been working on support, and Piotr kasprzak has tried HDMI audio support with OpenELEC 7.0 and a patched Linux Kernel 4.5.1, and confirmed it to be working on Tronsmart Ara X5 Plus and Wintel 10 Pro mini PC powered by Intel Atom x5-Z8300 processor. This can also be verified in the kernel log with dmesg:

If you want to try it yourself, you can download the OpenELEC image with the modifications. If […]

PiPO KB2 is a Foldable Keyboard PC Running Windows 10

We’ve already seen a few Windows 10 keyboard PCs, that look similar to the good old Commodore 64, are now being sold, such as K3 Wintel, but PiPO, a manufacturer that likes to try new ideas, has now designed a foldable keyboard PC powered by a Cherry Trail processor, and featuring a battery and support for WiDi for a cable-free experience. PiPO KB2 foldable computer specifications: SoC – Intel Atom x5-Z8300 processor @ 1.44 GHz / 1.84 GHz with Intel Gen8 Graphics System Memory – 2 or 4 GB RAM Storage – 32 or 64 GB eMMC flash + micro SD slot Video Output – HDMI Audio Output – HDMI and 3.5 mm audio jack Connectivity – Wi-Fi 802.11ac & Bluetooth 4.0, WiDi support USB – 1x micro USB port, 1x USB 2.0, 1x USB 3.0 Foldable QWERTY keyboard Battery – 2500 mAh The mini PC, or however you want […]

Doogee Smart Cube P1 Android Projector Unboxing and Quick Try

Doogee Smart Cube P1 is an Android 4.4 projector that looks somewhat like a Rubik’s cube, powered by Amlogic S805 processor and featuring Texas Instruments DLP solution. GearBest sent me a sample for review, and today, I’ll start by checking the device itself, before writing a review in a few days. The mini projector only ships with a 5V/2A power supply / charger, and its USB cable. So your smartphone will have to be the remote control, unless you connect an RF dongle for your air mouse or wireless keyboard. There’s also no user’s manual either. Not that I normally read them, but a description of the features would have still been nice. Anyway, it’s easy enough to find out. The projector is on one side, the blue and yellow side features with a USB port and reset pinhole, and the red and white side, the micro USB port for […]

MiQi Rockchip RK3288 Development Board using Raspberry Pi Form Factor to Sell for $35 and Up

Rockchip RK3288 processor may have launched in 2014, but it’s still one of the most powerful processor found in TV boxes for example, and in the past we’ve seen higher end board based on the processor such as Firefly-RK3288 or Radxa Rock 2 Square selling for well above $100. But MQMaker, the company that previously made WiTi router board, is bringing a smaller and cheaper RK3288 development board with MiQi, which definitely looks similar to the Raspberry Pi. MiQi board specifications: SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 1 or 2G DDR3 depending on model Storage – 8 or 32 GB eMMC flash depending on model + micro SD slot Video & Audio output – HDMI 2.0 up to 3840×2160@60p Connectivity – Gigabit Ethernet USB – 4x USB 2.0 host ports, 1x micro USB port Debugging […]

Xiaomi Mi Box 3 Enhanced Review

We’ve already taken Xiaomi Mi Box 3 Enhanced TV box apart in the unboxing and teardown post, and after changing the language to English, seen the performance is excellent thanks Mediatek MT8693 hexa-core processor, so I’ve done further experiments and tests with the device, and will report my findings in this review. Settings and Power Handling and Consumption Mibox 3 Enhanced boots reasonably fast I can get to the user interface within 30 seconds. We’ve already the main GITV user interface in previous posts, but I had not gone through the settings yet. There are eight main sections: Display Resolution settings – 3840×2160 @ 60/50/SMPTE24/30/24 Hz, 1080p @ 60/50 Hz, 720p @ 60/50 Hz, Scale and position – For overscan adjustment Sound Button sounds – On/Off Sony/Philips Digital Interface Format – PCM/Raw data (actually used for HDMI audio pass-through) System_update – MIUI TV firmware OTA update Device & Bluetooth – […]
