The Potential of Cloud plus IoT

I've heard some dubious claims contrasting the cloud and IoT. I've also seen the connection between the two overhyped and generally misunderstood. As the lead cloud engineer at an IoT company, I feel obligated both to provide context and advocate for a proper understanding of the potential of IoT plus cloud.

The Internet of Things Protocol Wars

Transformational technologies are inevitably the battleground for competing implementations and protocols, and the Internet of Things (IoT) is no exception. However, the evolutionary trajectory of two different markets makes this battle an interesting and unpredictable one.

Oracle IoT Kids Workshop

So I just finished prepping 50 Raspberry Pi kits and 25 Lego sets for a kids programming workshop tomorrow, and put the finishing touches on the 99 page slide deck. Given the workshop doesn’t start for another 6 hours, I think that is pretty timely.

Hacking the Teensy V3.1 for SWD Debugging

The Freedom boards are small, inexpensive and can be easily extended with Arduino shields which makes them a great platform for prototyping. But sometimes I just need an ARM microcontroller with some headers, and then the 85mm x 55mm size of the Freedom board is not ideal.

Wearable Innovation to Detect Heart Attacks

I’ve covered devices in the past year or so that have aimed to monitor and detect various elements pertaining to our health. Indeed the Tricorder X Prize competition is designed specifically to un-earth just such devices, with the challenge being to produce a mobile device that can detect several health signals.

Raspberry Pi B+: Connect to your Pi with no display monitor, keyboard or mouse

The moment I had this credit card sized thing on my palm, I was so excited to get started with it. But then, wait! Do you need a HDMI TV or display monitor, USB keyboard and a USB mouse to connect to it? Oh really!? I was not interested to invest any further. Here is what I did.

Raspberry Pi GPIO using OSGi Services

I've created an API that abstracts individual GPIO Pins as OSGi services, and made it available via the ECF github repository. This allows applications to easily use the Raspberry Pi's GPIO to send output to or receive input from peripherals.

Zumo Robot with WiFi and GPS

Removing the need for the Freescale FRDM board on the robot as in the previous design now makes it possible to stack normal Arduino boards on the robot. The pictures show the robot using the Adafruit GPS Shield and the Adafruit WiFi shield, making the robot really easily extensible with off-the-shelf shields.

Adding the Wi-Pi WiFi Dongle to the RIoT Android Board

The wired Ethernet connectivity works out of the box with the Freescale RIoT board. But to make it more ‘IoT’ capable, a WiFi connection would be a big plus. The element14 site did not tell which WiFi dongles are supported, and a thread in the element14 forum on that topic has not really provided much information.

Getting Started with Home Automation (Part I)

But first, lets start with a good old rant. Why is the world of home automation so badly organized? Let me come again; why? If you enter this world, set aside all open source principles. Do not hope that you are going to find centralized/useful documentation on how to do things.
