Why the word "drone" is scaring neighbors, creating bad legislation, and blocking an economic boom.

Sensationalist coverage and fabricated illustrations have cemented the word "drone" as a weapon in the public psyche. But it may not be too late to change public opinion about the technology behind the word.

A few years ago, a colleague and her husband, an ex-helicopter pilot, realized a tectonic shift was disrupting industries in which they had devoted entire careers.

This disruption had a passing resemblance to what happened to other American industries. The hard work once done by skilled, human hands was now being automated by the calculating actuators of a machine.

Automation had long since dominated the appliance, automotive, and electronics industries. But this was a brand new territory – aviation.

The reduced price and size, and the increased reliability and capability of processors, sensors and batteries meant unmanned aviation had been unleashed. A nouveau DIY revolution meant that basements and garages were once again incubating nascent technology, just as they did in the 1970s when the personal computer was being developed.

The silver lining is that the cost of search and rescue, disaster relief, monitoring wildlife, guarding endangered animals from being poached, and even medication delivery to underserved populations all could be slashed.

Like many other small startups in the unmanned aviation industry, my friend and her husband saw an opportunity. And despite criticism of slow progress on regulations, the Federal Aviation Administration also sees it. The FAA estimates that the market for commercial unmanned aerial systems will eventually reach $90 billion.

The Association for Unmanned Vehicles and Systems International (AUVSI) believes there will be an economic impact of $13.6 billion within 3 years that unmanned aircraft are integrated into the national airspace.

Where to start? What better way to get acquainted to the industry than attend one of the premier industry conference in the nation, hosted by AUVSI?

She learned about new applications for unmanned aircraft. She listened to a UAV operator who used his homemade robotic aircraft to assess flood damage in Thailand. The information gathered from the aerial vehicle allowed the government to make decisions that mitigated flooding in the country’s capital.

This was great. But when it came to talk shop, things became awkward when she used a five-letter word that began with the letter “d.”

“The conversation would just stop,” she said. “Just completely stop dead.”

Finding a definition and purpose for sensor journalism at the Tow Center

Before I left for the Tow Center's sensor journalism workshop at Columbia University last weekend, my wife and I hosted some friends for a spinach lasagna dinner. On the stack of books my wife was researching for her dissertation on toxins in science fiction, sat my latest obsession, the DustDuino sensor node.

While we ate, the node's tiny LED lights blinked away as it took particulate matter readings every 30 seconds. A friend pointed out the interesting juxtaposition of the pollution monitor siting on a copy of Rachel Carson's Silent Spring. Our friend's husband, an entomologist, asked what it was all about.

"Part of the idea is to have people make these all over the country, especially places with bad air," I said.

"Interesting," he said. "You know... that doesn't sound much like journalism," he said. "It sounds like research."

I thought about it for a moment, and took a sip of the lemon-and-bourbon cocktail my wife prepared. I didn't have a good answer.

"Journalists are kind of unemployed at the moment, so we're looking for other things to do," I replied.

For me at least, the Tow Center's workshop helped find an answer to that question, and provide a deffinition and goal for sensor journalism. About 50 folks with backgrounds in journalism, science, architecture, community informatics, and computer technology came to the Tow Center's first sensor journalism workshop on June 1-2.

I owe a big debt to the organizers of this event: Emily Bell, the Tow Center director; Fergus Pitt, Tow research fellow; Taylor Owen, Tow research director; along with Laura Kurgan, director of the spatial design lab at Columbia; and Chris Van Der Walt and Sara Jayne Farmer of Change Assembly, Inc.

Step-by-step guide to programming the RN-XV WiFi module for Arduino

The Arduino prototyping standard has been around for about 6 years now, and has proven to be immensely useful for sensing devices. It's the heart of the DustDuino and many other sensor nodes.

But for all the flexibility that the Arduino provides for collecting data about the environment, there still isn't a reasonably-priced, reliable shield to send data via WiFi.

The official Arduino WiFi shield, while well-supported, costs around $85. That's a pretty high price to connect a $4.50 chip to a network. Cheaper options such as the WiFly shield do exist, but some of the libraries supporting these devices are difficult to decipher or unstable, if they exist at all.

I spent a long time myself looking for a cheap, effective WiFi solution for the Arduino platform, and I've been very pleased with the $35 RN-XV module.
