Texas Instruments Sensortag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application, which I recently tried in Linux. Until now, only it was only officially supported in iOS and Windows, but a few days after the release of Android 4.3 which adds Bluetooth Low Energy support, Texas Instruments quickly worked to release an Android App for their BLE devkit. The annoying part is that the Android app is only available as a Windows executable (SensorTagAndroidApp-0_9_0-windows-installer_2.exe), so you’ll have not choice but to use Windows to uncompress the files. Yet the installation goes as follows: Copy the SensorTag.apk file (SensorTag_0_9_0.apk) to your Android 4.3 device Enable installation of apps from unknown sources (Settings -> Security -> Device Administration -> Unknown Sources) Open file manager and launch, locate the .apk file and install the app by clicking the […]
Tizen Developer Conference 2013 Presentation Slides, Audio Recording and Videos Are Now Available
The Tizen Developer Conference took place in San Fransisco, on May 22-24, 2013. We’e already seen a few Tizen demos from the conference, but slides and media files (mostly audio, but also some videos) are now available for keynotes and technical presentations. As this was just the second Tizen conference, there were still many sessions dealing with overall structure of the operating system, and explaining how to get started either with native or web development, such as: An Overview of the Tizen Native Application Framework Introduction of Tizen SDK minimal web development tools Tizen Design Guidelines and User Experience Tizen Overview and Architecture Tizen.org Web Infrastructure Tizen enters a mobile world dominated by Android and iOS, so several sessions targeted app developers used to work with either operating systems in order to show them how to port their existing apps to Tizen: Bringing Android Apps to Tizen From iOS to […]
Scanadu Scout Medical Tricorder for Android and iOS
Low cost personal medical tricorders have the potential to dramatically bring down the cost of health care, and avoid unnecessarily wasted time in hospitals, which is probably the XPRIZE Foundation has launched a competition for medical tricorders, where the winners will get 10 millions US dollars in funding. Scanadu Scout is one of the entry, and they currently have an indiegogo campaign, already oversubscribed, for their medical grade tricorder which gather data by placing it on your forehead for 10 seconds, and display medical data transferred via Bluetopoth Low Energy (Bluetooth SMART) on your iOS and smartphone. The company did not disclose full specifications, but they still revealed the device runs 32-bit Micrium RTOS, which is already FDA approved (pre-market 510K notification and PMA approval), it supports Bluetooth 4.0 SMART, and a micro USB port is included to recharge the battery. I fired up few Google image searches to look […]
$25 Texas Instruments SensorTag is a Bluetooth LE Devkit with 6 Sensors
Yesterday, I wrote about Wimoto Motes, tiny Bluetooth LE devices with several sensors that can be controlled and monitored via an iOS app, and soon by an Android app, as well as Linux devices. Each mote costs $39 plus shipping, and one commenter mentioned the price may be a bit too high. A Google search for “bluetooth sensor” immediately brings TI SensorTag, which looks somewhat similar, except it is a Bluetooth LE development kit, includes 6 sensors (but no light sensor), and only costs $25 including shipping. SensorTag Specifications: Bluetooth 4.0 low energy (CC2541) SoC 6 sensors connected via I2C: IR Temperature sensor (TI TMP006) Humidity sensor (Sensirion SHT21) Pressure sensor (Epcos T5400) Accelerometer (Kionix KXTJ9) Gyroscope (InvenSense IMU-3000) Magnetometer (Freescale MAG3110) Power – Single cell coin cell battery (CR2032), quiescent current consumption of 8uA, allowing years of battery life. FCC, IC and ETSI certified solution Dimension – 71.2x36x15.5 mm, […]
Wimoto Motes are Tiny Bluetooth Sensors for iOS, Android, and Linux Devices
Wimoto Motes are small (30x30x8mm) wireless sensors that communicate temperature, humidity, soil moisture… values to your iPhone, iPad, Android, and Linux (yes, including the Raspberry Pi) devices via Bluetooth. They are said to last for about a year on a single CR2032 battery and don’t require an Internet connection to work, but you can still upload your data to Wimoto cloud service via the app, or use an optional mote.cloud bridge to do it for you in realtime via Wifi. There are currently 4 Motes: Climote – Measures light (0 to 60,000 lux), temperature (-25 to 85 C) and humidity. Used to monitor a room environment (bedroom, cellar, greenhouse,…), and tell you if you need to make adjustment Growmote – Measures sunlight (0 to 60,000 lux), soil moisture (5 levels) and temperature (-25 to 85 C), to make sure your lawn or flowers are not thirsty. Thermote – Measures an object temperature […]
Watch and Record Live TV on Android or iOS Mobile Devices with Geniatech WiTV
If you’ve ever wanted to watch live digital TV on your tablet or smartphone, there’s now a solution. Geniatech WiTV is a tiny battery powered DVB receiver also acting as Wi-Fi access point in order to stream live TV to your mobile devices. You can use this device within your house or on the go, but it has to be within 5 to 7 meters from your tablet or smartphone to work properly. The specifications released are limited, but we still know the following: Frequency range – 177.5 – 226.5MHz (VHF); 474 – 858MHz (UHF) Digital TV standards – DVB-T Mpeg 2, Mpeg 4 and H.264; ISDBT oneseg 802.11 b/g/n WiFi Standard Support Micro USB for recharging Up to 3 hours of TV viewing (TBC) iOS devices must run IOS 5.0 or IOS5.1, and Android 3.0 or greater is supported. You’ll need to install SianoTV for Android or iOS, scan […]
$55 AX-14 DLNA, WiDi & Miracast Dongle Works with Android / iOS Devices, and Windows 7/8 PC
Miracast is a new standard allowing you to play videos or mirror your Android device display on a TV via Wi-Fi direct. All you need is a Wi-Fi device that can be connected to the HDMI and USB (for power) ports of your TV, and decode common video codecs. There are not many devices available on the market, but I’ve just found out about AX-14, a Wi-Di and Miracast HDMI adapter that lets you connect your Windows 7 or 8 to your TV via Wi-Di, or your Android / iOS via Miracast. The device also supports DLNA. The hardware specs are said to be as follows: Processor – MIPS24Kc processor (RTD1185PA) @ 500MHz System Memory – 256 MB DDR3 SDRAM Storage – 128 MB NAND Flash Video and Audio engine with HW acceleration Video Codecs & Formats – MPEG-1,MPEG-2,MPEG-4 SP/ASP( Xvid), MPEG-4 AVC(H.264), AVS, VP6, Motion JPEG, H.263 , H.264, […]
Headless Connected Oscilloscope based on Cubieboard or Beaglebone
Warsaw ELHEP (Electronics for High Eenergy Physics Experiments) Group is currently working on MMS (Mobile Measurement System) Project. This project features what I would call a “headless connected oscilloscope”, which can be detected on the network via SSDP, send the data via Websocket, and display it on iOS, Android, or Windows Phone devices. This oscilloscope does not feature any screen, and receives/transmits data via Ethernet, Wi-Fi, or Bluetooth. The original hardware is based on three main boards: CTI-VMAX – ARM9 with Wi-Fi, Bluetooth, and Ethernet connectivity. ARM SCOPE v1.0.1 with 8 channel ADC. ARM SCOPE v1.0.2 with 4 high speed ADC (100MSPS). The ELHEP researchers have been looking at replacing CTI-VMAX with low cost boards, and after considering several options, they chose to design two versions of their oscilloscope: one based on Cubieboard, and the other on the Beaglebone. So they designed expansions boards for the Cubieboard and Beaglebone in […]
