Raspberry Pi () has come up with a computer for $5. Well, even the other Raspberry PIs were not very expensive ($20 ~$30). It also attests to the fact that IoT is catching on. It has become so cheap that some magazine (MagPi) gave it away to its readers bundled with the issue. According to a pcworld.com article (IDG News Service) it uses a 1 GHZ ARM processor from Broadcom (BCM2835). It has 512MB RAM with the OS loaded on the micro-USB card. It has Micro-USB sockets for data and power including a mini-HDMI socket as well. It has a 40-pin GPIO and the circuit-board may require soldering by customers. Image source of of Raspberry Pi Zero with MagPi is here. Here is a PDF document for BCM2835 Processor. Here is the YouTube video: ... (more)

Optomec and IoT | @ThingsExpo #IoT #M2M #ML #InternetOfThings

IoT depends to a large part on the availability of custom hardware of sensors that can be efficiently manufactured with exacting tolerances in its specifications. Smart Parts manufacturing will be one of the key technologies required to address the IoT 3D Sensors and 3D Antennae. Optomec which manfuactures production grade 3D printers can manufacture parts both in plastics and metals. Here is a picture showing some of the smart stuff that can be made using Optomec 3D Printers. The parts made with additive printing uses the Aerosol Jet Process (no different from spraying a liqui...

Azure Data Lake Store in Private Preview | @ThingsExpo @ScottGu #BigData #IoT #InternetOfThings

Azure Data Lake Store in Private Preview Recently announced Azure Data Lake addresses the big data  3V challenges; volume, velocity and variety. It is one more storage feature in addition to blobs and SQL Azure database. Azure Data Lake (should have been Azure Data Ocean IMHO) is really omnipotent. Just look at the key capabilities of Azure Data Lake: Any Data Native format, distributed data store. No need to pre-define schema information. From unstructured to structured data handling. Any Size Kilo bytes to Exa bytes OK. Ready for read/write. At any scale Scale to match your needs; ... (more)
