$14 Marstek MPR-N9 WiFi/3G Router with 2,400 mAh Battery

One of my readers (Onebir) brought Poray M3 mini Router to my attention a few days ago, as it just cost $17 at the time (now over $20) and OpenWRT developer Squonk seems very interested about it since it features microSD and SD card slots missing in TL-WR703N. However, the device only has 16 MB memory which makes it somewhat difficult to run OpenWRT, or at least some of its features. But today, I’m not going to talk about this. Mentions of Poray M3 router came in HAME MPR-A1 OpenWRT forum thread, and I discovered a new (to me) type of low cost, small form factor device: portable Wi-Fi/3G routers. Those devices are about the size of android mini-PC and contain the chips to handle Wi-Fi, USB host (for external 3G dongle), and comes with a built-in battery so that you can use them anywhere (beach, mountain, car…), as long […]

Digi Launches XBee Modules Examples Website To Get Started with IoT Development

Digi International has launches an example section on their website to showcase what can be done with their XBee 805.15.4, ZigBee and WiFi Modules, as well as their IoT gateway. They provide examples to use different type of sensors, control lights, motors, and more. They show demos on the website and explain how each components can be linked together, hooked to computers and connected to the internet. They currently just have a few tutorials only, but plan to add more overtime: Basic XBee 802.15.4 & Zigbee Chat 802.15.4 PWM and Digital Output with an LED 802.15.4 Digital Input with a Button 802.15.4 Analog Input with a Potentiometer Light Switch XBee – A wireless wall switch that can control lamps, fans, motors or your homemade robot The first four examples look good to get started, but the Light Switch XBee is the most interesting, and they describe 8 steps to show […]

Android Transporter Enables WiFi Display Mirroring (similar to Miracast) of Android Devices

E.S.R.Labs is a German embedded software company mainly working for the automotive industry. But this time, they’ve started to work for the consumer market with Android Transformer, a software solution that can mirror an Android display to another Android device display via Wi-Fi in a similar fashion to what WiFi Miracast will do. Eventually, the company plan to make Android Transporter compatible with Wi-Fi Miracast, but in the meantime they rolled out their own solution by taking advantage of H.264 hardware encoders and decoders on Galaxy Nexus S and the Raspberry Pi. If they use standard APIs, I assume any hardware running Android that with H.264 hardware encode/decode should support their platform. I hope it will be work on (or be ported to) CX-01 mini PC which can be bought as low as $40 inc. shipping. It would make an even cheaper hardware than the Raspberry Pi (Up to 33% […]

Texas Instruments Unveils Wi-Fi CERTIFIED Miracast Video Streaming Solution Based on OMAP 4

In my previous post, I wrote about Marvell announcement of its new 802.11ac chipset (Avastar 88W8897) that will be Wi-Fi CERTIFIED Miracast. But it’s not the only company for such solution, as Texas Instruments has also announced the availability of a complete solution for mobile devices designed to support Wi-Fi CERTIFIED Miracast, based on the Wi-Fi Alliance Wi-Fi Display Specification that enables users to reliably display high definition content from a mobile device onto a larger screen over a secure, low-latency, wireless network connection. The Miracast certification program defines a standards-based solution for streaming video and audio content over a peer-to-peer Wi-Fi Direct wireless network. TI solutions will leverage OMAP processors and its WiLink connectivity solutions to provide a Miracast platform. This new solution will be available later this year to power mobile phones, tablets, HDTVs, projectors and audio receivers. Texas Instruments solution will provide the hardware and software resources […]

Marvell Avastar 88W8897: Wifi 802.11ac, NFC and Bluetooth 4.0 Chip

Marvell has announced the Avastar 88W8897, a low-power radio chip supporting 802.11ac, near field communication (NFC) and Bluetooth 4.0, aimed at mobile and HD multimedia devices such as ultrabooks, tablets, gaming consoles and smart TVs. Marvell claims the 88W8897 SoC enables a rest of bill of materials (RBOM) footprint reduction of 40-to-50 percent and cost reduction of 75 percent compared to previous wireless solutions. Key features of Marvell Avastar 88W8897 chip include: Wi-Fi 802.11ac – This standard increases bandwidth available over the Wi-Fi link (theoretically up to 1 Gb/s) with throughput up to 867 Mbps for the 88W8897. This kind of throughput allows reliable high-definition (HD) video streaming, tunneled direct link setup (TDLS) and high-speed wireless backup and sync for mobile devices. NFC – NFC allows consumers to pay for items with the tap of a phone via mobile commerce and point-of-sale (e-wallet) applications. It can also enable one-tap pairing […]

25 USD Hacker Friendly Electric Imp “WiFi-ises” Your Coffee Machine

Electric Imp is a device in an SD card form factor that aims at providing Wi-Fi connectivity to household appliances at low cost and bringing the Internet of Things (IoT) closer to reality. The Imp will also connect to a Cloud service handled by the company (which is also called Electric Imp). The device Wi-Fi connection can easily be configured using an iOS or Android smartphone thanks to BlinkUp, a patent-pending scheme supporting WEP, WPA and WPA2 encryption schemes as well as WPS setup. Electric Imp developers expect this device to save resources (e.g. electricity) by taking into account environmental conditions (e.g. occupancy, temperature..), improve security & safety and overall provide better monitoring and control of devices. For example, this could enable support services to remotely diagnose a device, and provide timely customer support. Here are the Electric Imp hardware specifications: ST Micro STM32 Cortex M3 MCU 802.11b/g/n WiFi 6 […]
