Immedia Blink Battery Powered HD Security Camera Lasts Over One Year on Batteries (Crowdfunding)

There are plenty of security systems with IP cameras selling on the market, but they can be a pain to install because you need to use long power cables or use power extensions. There are battery-free such as NETGEAR VueZone Home Video Monitoring System that cost $259 with 6-month battery life for normal usage, and $50 yearly subscription fee. Immedia Semi is providing an alternative with Blink, a wire-free (wireless + battery) HD Home Monitoring & Alert System that starts at $69 with one camera, and is said to last over one year powered by two CR123 batteries, without monthly fees, and can stream live views and video recordings to your Android or iOS smartphone or tablet, or any web browser. The one-year battery claim seems preposterous. How is that possible? The first reason it’s possible is because of the way typical usage is defined for home security cameras. They […]

DIY Power Measurement Board

When I review media player or development boards, I’m often asked about power consumption figures. One way to measure power consumption is to use a Kill-a-Watt, but for low power devices it’s not always accurate enough, and it also includes the heat dissipation from the power adapter, which may or may not be useful depending on what you want to measure. For USB powered devices or boards, an easy way to measure power consumption is to use CHARGER Doctor, a small $5 USB dongle that displays both voltage and current alternatively. Unfortunately, most products I’ve received lately use barrel type connectors, so this little tool has not been as useful as I hoped. The only solution is then to measure voltage and current with a multimeter. Voltage is measured in parallel, so you just need to point the multimeter’s leads where you want to perform the measurements. However, the current […]

ARM TechCon 2014 Schedule – 64-Bit, IoT, Optimization & Debugging, Security and More

ARM Technology Conference (TechCon) 2014 will take place on October 1 – 3, 2014, in Santa Clara, and as every year, there will be a conference with various sessions for suitable engineers and managers, as well as an exposition where companies showcase their latest ARM based products and solutions. The detailed schedule for the conference has just been made available. Last year, there were 90 sessions organized into 15 tracks, but this year, despite received 300 applications, the organizers decided to scale it down a bit, and there will be 75 session in the following 11 tracks: Chip Implementation Debugging Graphics Heterogeneous Compute New Frontiers Power Efficiency Safety and Security Software Development and Optimization Software Optimization for Infrastructure and Cloud System Design Verification There are also some paid workshops that take all day with topics such as “Android (NDK) and ARM overview”, “ARM and the Internet of Things”, or “ARM […]

Imagination Technologies Unveils Low Power Low Footprint PowerVR GX5300 GPU for Wearables

Up to now most wearables are based on MCU solutions or derived from mobile platforms, which may either not provide the advanced features required by users, or consume too much power and take more space than needed. With Ineda Dhanush and Mediatek Aster, we’ve already seen silicon vendors design wearables SoCs, and now Imagination Technologies has just announced PowerVR GX5300 GPU targeting wearables with support for OpenGL ES 2.0, 480p to 720p resolution, and using 0.55mm2 silicon area based on 28nm process. PowerVR GX5300 GPU will be support Android, Android Wear, and Linux based operation systems, and according to the company has the following key features: Unified shaders – The TBDR graphics architecture offers unified shaders where vertex, pixel and GPU compute resources are scaled simultaneously. Low power and high precision graphics – All PowerVR GPUs offer a mix of low (FP16) and high precision (FP32) rendering and implement the […]

Tronsmart Mars G01 Wireless Gamepad Review on Android

One way to play games in Android TV Box with a gamepad is to use a Sony Playstation 3 Controller with Sixaxis Controller app. It can work, but you need a device that supports Bluetooth, with the right drivers, and most games require you to do the mapping manually which is not that user-friendly. Now, they make Android compatible Bluetooth Gamepad such as G910 which seems really nice, but I’ve been told it’s rather hit or miss, and some people have problem with the Bluetooth connection. GeekBuying instead recommends Tronsmart Mars G01, based on 2.4 GHz technology, that requires an external USB RF dongle, but which alledgly does not have connection problems. It works with Android, Windows, and Playstation 3. The company sent me a sample, so I’ve taken some pictures and tried a few games with Tronsmart Vega S89 Elite TV box. Tronsmart Mars G01 Unboxing I’ve received the […]

Thread is a New IP-based Wireless Protocol Leveraging 6LoWPAN and 802.15.4 Standards

Wi-Fi is a neat way to connect devices to Internet, but it has two main inconveniences: relatively high cost and power consumption. Luckily there are standards that addresses the cost and power consumption issues. Radio chips based on IEEE 802.15.4, a standard which specifies the physical layer and media access control for low-rate wireless personal area networks, are common place and found in many existing devices relying on higher level wireless protocols such as ZigBee, ISA100.11a, WirelessHART, and MiWi. AFAIK, Zigbee is the most popular of the aforementioned protocols, but is hindered by the requirements of the license for commercial products (annual fee), Zigbee membership requirements conflict with many open source license such as GPL, and the standard suffers from lack of interoperability and IPv6 support, and power requirements that are too high for some applications. So a consortium of seven companies namely ARM, Big Ass Fans, Freescale, Nest, Samsung, […]
