Kaiboer F4 / Ugoos UT1 Quad Core Media Player Is Now Available for as Low as $116

K-R42-1 (aka CS918 aka MK888 aka …) has been one of the first Rockchip RK3188 Android TV Boxes available on the market, and can be purchased for less than $90 US. Kaiboer F4, discovered at the end of June, has similar specs, but comes with 2 Wi-Fi antennas, potentially improving Wi-Fi reception. The only problem. until now, was that it was not available for sale, but this has now changed, and you can purchase it for $116 including on GeekBuying, renamed as Ugoos UT1. It’s also available on Aliexpress at higher prices at the time of writing. [Update: Dealsprime sells it for $109.99] Kaiboer F4 / Ugoos UT1 Specifications: SoC – Rockchip RK3188 up to 1. 8 GHz with Mali-400 MP4 GPU System Memory – 2GB DDR3 Storage – 8 GB Flash + 1x SD card Video Output – HDMI, and AV Audio Output – HDMI,  AV, and optical S/PDIF […]

Borderless Electronics Sells $9 Arduino Compatible Starter Kit

The Raspberry Pi fundation, a nonprofit organization, has brought a low cost ARM Linux platform to the masses, and Arduino already did that with electronics, but Harold Timmis, an engineer, found out it was still not cheap enough as he worked as a volunteer teaching electronics at his library. So he (and others) decided to clone Arduino Leonardo, setup a website called Borderless Electronics, and sell it without profit via Indiegogo for just $9 ($12 including shipping). The board is indeed the same as Arduino Leonardo with different color, logo, and name: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 […]

The Little Black Box XBMC STB Gets Users’ Feedback, Becomes Available on Amazon

The Little Black Black Box (TLBB) is an set-top box running XBMC powered by AMLogic AML8726-M3 with 1GB RAM, 4GB Flash that comes with a dual sided RF remote control. The device became available for pre-order in April, and the first customers have started to receive the media player, one of them (flipfoelyfe) has uploaded a video, and posted some pictures. After initial issues setting up Wi-Fi (A bug seems to prevent the use of long passwords), his tweets about the device are rather positive, and he uploaded a short video demo showing Sports-a-Holic plugin playing a live NBA match, and a ESPN Boxing program. Whereas you had to pre-order and be patient for the first batch, LTBB is now available on Amazon for $129.99. Considering it also includes a dual sided RF remote control with a QWERTY keyboard, this single core set-top box is about the same price, or […]

Texas Instruments SensorTag Unboxing, Getting Started with Bluetooth Low Energy in Linux (with a Raspberry Pi)

Texas Instruments CC2541 SensorTag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application developers for iOS, and soon, Android 4.3. I’m interested in BLE, as I expect most new phones with come with BT 4.0 BLE (aka Bluetooth SMART), and this technology may help bring the Internet of things to life, allowing us to interact with sensors, smart appliance (e.g. light switch)… Since it just costs $25 (including international shipping), I decided to buy it, and give it a try. Today, I’ll show some unboxing pictures, and how to communicate with the kit using the Linux command line. TI SensorTag Unboxing I ordered it at the end of May, and receive it by Fedex on the 18th of July, about 7 weeks later, in the package below. Inside we’ve got a Quick Start Guide for iOS […]

WigWag Simplifies Home Automation, Provides Raspberry Pi and Arduino Shields

WigWag is an home automation kit aiming at simplifying home automation, yet allowing developers to roll their own system via Arduino and Raspberry Pi Shields. Wigwag is currently composed of three devices: WigWag Sensor Block – Universal sensor device with 8 environmental sensors (light, detect motion, sound, temperature, humidity, movement…), 4 control features (relay, IR blaster…), and 2 expansion ports. It can be powered by 4x AA batteries (possibly for up to 1 year), or a USB power adapter. This device runs Contiki OS on Freescale MC1322 MCU (with built-in 6LoWPAN radio). WigWag Relay – Connects WigWag and third party devices to their cloud service, allowing interaction with Internet services, such as email, Dropbox and Twitter. It acts a bit like a central server managing all your WigWag Sensor Blocks or other connected devices such as Phillips Hue light bulbs or Belkin WeMo outlets in your house. IP networks (Wi-Fi & Ethernet) […]

Risun D05 is an Android TV Stick Powered by Rockchip RK3068 SoC

I’ve just discovered another dual core Rockchip SoC called RK3068, but it may not be new, as I can find some references as far back as September 2012. Amazingly, I can’t seem to find any announcement, and details are scarce. Very few products feature this chipset, but Risun D05, an Android mini PC, is one of them, so let’s have a closer look. Risun D05 specifications based on Alibaba listing: SoC- Rockchip RK3068 dual core ARM Cortex A9 @ 1.6 GHz with dual core Mali-400 GPU System Memory – 1 GB DDR3 Storage –  4 GB NAND Flash, with option for 8GB or 16GB, + micro SD card slot (Up to 32GB) Video Output – HDMI 1.4 male Video Codecs – MPEG 1, MPEG-2, MPEG 4,H.263, H.264, AVS, VC 1, RV, VP6 VP8, Sorenson Spark, MVC 1920x1080P 60FPS. Video Encoder – H.264,VP8,MVC(1080P) Audio Formats – MP1, MP2, MP3, WMA, WAV, OGG, […]

Lernstift Digital Pen Hits Kickstarter for $150

Lernstift is a digital pen running Linux that aims at helping children learning how to write by vibrating when they’ve made calligraphy or orthography errors. I’ve covered the overall concept in an earlier post, which you can read for details. The company has made some progress, and they have just launched a kickstarter campaign where you can pledge 99 GBP (about $150) to receive the pen later this year or in early 2014. We do know a little more technical details. The first prototype was based on Gumstix Overo (TI OMAP3 or Sitara), but they are now working to design a custom board based on the platform for the final design. The pen comes with 128 MB RAM and runs embedded Linux. In order to gather handwriting data, Lernstift leverages a motion sensor that combines gyroscope with accelerometer, and adds a magnetometer. They’ve got a drawing with Freescale MMA9950L, but […]

Hacking MK908 mini PC for Serial Console Access

Thanks to Omegamoon (and this brother) we already have instructions to connect the UART pins on MK808 in order to access the serial console. He’s done it again with MK908 mini PC featuring Rockchip RK3188. Tx and Rx pads are located on the RAM chips side, and he has connected the green wire to Tx (Going to Rx on TTL debug board), and a yellow wire to Rx (Tx on debug TTL board). A ground pad is available on the other side of the board. Since I got a sample for review from Geekbuying, I decided to give a try myself. The pad are quite small, so this may require patience, but it’s perfectly feasible. I wanted to keep the device closed, so I passed the wires through the ventilation holes (enlarging them a bit with a precision screwdriver), put back the main heatsink on RK3188, and reassembled the enclosure.
