Vigekwear is a Modularized, Open source, Wearable BLE Development Kit (Crowdfunding)

[Update: Atomwear has been renamed to Vigekwear due to (Intel’s) copyrights infringement]. Giayee is a company mainly manufacturing Android tablets, thin clients, and mini PCs, but their latest product, called Atomwear, is a Bluetooth Low Energy (BLE) development kit based on Nordic nRF51822 chipset that comes with various modules such as battery charger, accelerometer, gyroscope, OLED display, heart rate monitor, etc… which connect together via 24-pin connector on a standard rigid baseboard or a flexible printed circuit (FPC). All modules are connected via the same 24-pin connector with power, I2C, SPI, UART, ADC, and GPIOs signals. The baseboard and FPC both contain 6 such connectors connected in parallel for up to 6 modules, and two baseboard can be connected together via a bridge circuit to accept more modules. The minimum configuration is with a BLE MCU module, and a power module. The different boards and modules are listed as follows: […]

Parallax Propeller 1 P8X32A Open Source Multi-core MCU

Lots of electronics devices are now powered by open source software such as Linux, open source hardware is not as wide-spread, but gaining tracking traction thanks to the like of Arduino, Beagleboard.org, Olimex, and many  projects on crowdfunding websites, and now we even start seeing some open source silicon. Existing open source processors include LEON3 (SparkV8) MCU, OpenRisc, and just very recently, LowRISC, based on 64-bit RISC-V instruction set architecture, has been announced with the backing of some of Raspberry Pi co-founders, Google ATAP, etc… and is currently being developed at the University of Cambridge, UK. Parallax Propeller 1 P8X32A is another MCU which has been open sourced last week.   Propeller 1 P8X32A had however been released in April 2006, and can be sourced as a 40-pin DIP chip for prototyping, and 44-pin QFP and QFN for production, and come with the following key features: Power Requirements: 3.3 VDC […]

Rockchip RK3288 Temperature Testing and Antutu Benchmarks

There are many upcoming Rockchip RK3288 based devices, and in the listing the CPU frequency varies from 1.6 GHz to 2.0 Ghz. so it’s difficult to know exactly what to expect. Ugoos has done some testing with their UT3 board measuring temperature after Antutu benchmark for different CPU clock frequencies and fan/fanless combinations. The board comes with a rather tiny heatsink which may explain some of the results below. They also added a small fan on top in about half the tests to compare the temperature against an heatsink only solution. Without further delays let’s go through the results: Frequency Antutu Score Temperature (heatsink) Temperature (Back of PCB) Heatsink only Heatsink + fan Heatsink only Heatsink + fan 1.608 GHz 38655 67 °C N/A 70 °C N/A 1.704 GHz 39853 72 °C 50 °C 75 °C 60 °C 1.800 GHz 41440 83 °C 52 °C 85 °C 62 °C 1.920 […]

Acer CB5 Chromebook To Feature Nvidia Tegra K1 Processor, 13 Hours of Battery Life

It seems Nvidia Tegra K1 is getting in more hardware than its predessors. It can not only be found in Jetson TK1 development board and Shield tablet developed by the company, but also products such as Xiaomi MiPad, as well as Google Tango Project Tablet devkit. Acer CB5 Chromebook should also launch very soon with Tegra K1 quad core processor, a 13.3″ display, and the company claims it should last 13 hours based on Google’s power_loadtest. Preliminary specs for Acer CB5 Chromebook: SoC- Nvidia Tegra K1 quad core Cortex A15 @ 2.1 GHz with Kepler GPU System Memory – 2 to 4 GB DDR3 Storage – 16 / 32 GB flash Display – 13.3″ display with 1366×768 or 1920×1080 resolution (TBC) depending on model, and optional touchscreen support Video Output – HDMI Audio – 3.5mm audio jack, speakers Connectivity – 802.11 b/g/n/ac Wi-Fi USB – 2x USB 3.0 ports, 1x […]

100KHz-1.7GHz RTL-SDR USB Tuner Receiver DIY Kit Sells for $33

Software-Defined Radios (SDR) are neat little devices that capture radio signals which are then filtered and decoded by software on your PC or embedded system. The currently used radio spectrum is extremely wide from 3 to 30Hz for submarine communication up to 30 to 300+ GHz or more for applications such as amateur radio or radio astronomy. So the price of hardware needed for SDRs varies greatly depending on the frequency range supported, bandwidth, and other technical parameters. Hobbyists can use “low cost” ($300 – $400) FPGA SDR boards such as bladeRF or HackRF, or go ultra-cheap with $20+ RTL-SDR USB TV tuners. I’ve been informed there’s a development kit sold under the name “100KHz-1.7GHz Full Band UV HF RTL-SDR USB Tuner Receiver DIY Kit” based on the latter, but with extra components, on various sites such as Buyincoins, Ebay, Aliexpress, etc.. for just $33 to $45. The problem with […]

Mele F10 Deluxe Air Mouse Review

Mele F10 is an air mouse using 2.4GHz RF technology, that can be used as a remote, a QWERTY keyboard, and a wireless mouse. That’s my favorite input device for Android TV Box, and I use it regularly for my product reviews. The company has now introduced an improved model called Mele F10 Deluxe with trick mode buttons, a gaming mode thanks to a gyroscope, and an IR learning function to use it as a universal remote. Mele sent me a sample for evaluation, so I’ll start with some unboxing pictures, and compare it to the original Mele F10, before testing the remote. Mele F10 Deluxe Unboxing I’ve received the air mouse in the package below that highlights the four main features: Air mouse, Game Controller, Wireless Keyboard, and IR Learning. We’ll find the air mouse, a tiny RF dongle, a USB cable for charging, and a user’s manual describing […]

EasyEDA is a Web-based Schematics Capture, Simulation, and PCB Layout Tool

I recently watched a video showing AllWinner R&D, and I noticed although most (all?) software engineer run Ubuntu in the PC, the hardware engineers all relied on Windows based EDA tools for schematics capture and PCB Layout. There are already Linux-based tools such as Kicad, which appears to be good for new projects, but importing existing projects can be an issue. An alternative to operating system dependent EDA software suites are web-based tools. I’ve already tried Fritzing which allows to draw circuits on breadboard, convert these to schematics and PCB layouts, and order the PCBs. It looks pretty good for its purpose, but it’s limited to mostly simple designs, and AFAIK can’t be used to replace an EDA suite. That’s where EasyEDA comes into play.  It’s a web-based tool where you can draw schematics, perform simulation, and create PCB layouts for your project, either keeping them private, or sharing them […]
