Dan Shiffman and I are working on a Processing library for Digi’s XBee Series 1 radios. The library currently facilitates receiving single sample I/O packets in API mode, and returns an object that contains the analog values, digital values, sender’s 16-bit address and RSSI value. The next tasks will be to receive regular RX frames, […]

On the Arduino microcontroller, the millis() function counts the number of milliseconds since the program started running. Unfortunately, this count resets to zero after approximately 9 hours and 32 minutes. I have written a millisRollover() function that detects these rollovers, so that programs can respond properly to the overflow event. This can solve problems with

This week I was asked to help out with final mesh network creation and configuration for the Living City project, going on exhibit starting December 11th at the Van Alen Institute’s public gallery. The project is the brainchild of The Living’s two architects, David Benjamin and Soo-in Yang who are currently resident fellows at the

Nearly a year ago, I created the ITP BlogBlender. This site compiles all the blogs written by current members of the NYU Interactive Telecommunications Program community into a single digest. This fall has seen a flurry of server changes, software upgrades, protective adjustments and layout improvements–all in preparation for the next big rollout: This month

The Lantronix Matchport is an embedded WiFi module used to gateway serial information to the Internet via 802.11.b/g wireless. Normally it must be configured to work with a specific WiFi network, which means that can’t roam from place to place without being manually reconfigured. While this is fine for a device that will be installed

Normally, I let my sister’s talents speak for themselves. However her new book The Terror Dream received such a flattering review in the New York Times Sunday Book Review today, I’m compelled to post a link and bask a moment in reflected glory. As her brother, I’ve always been a fan. This latest opus features

Radio is tough to understand intuitively. There’s plenty of physics to describe its behavior, but it can’t be seen, smelt, felt or heard without special equipment. Radio waves travel without a medium, so the common terminology of “airwaves” is quite misleading. There’s no need for air. Defining it as “wireless” is not helpful. That doesn’t

These coffee cups always make me laugh. Monolithic corporations love each other. (Next week is my last here at Microsoft Research. sniff)

National Public Radio’s Morning Edition show did a little piece on Botanicalls today. They made a genuine effort to be charming so give Steve Inskeep’s piece a nice listen. Thanks again to Josh for lending his voice to the Fiddle Leaf Fig.

Spent the weekend with friends in San Francisco who are building an art car out of an Chevrolet El Camino. I helped design circuits for nighttime running lights and spent several laborious hours tweezing tiny beads onto the adhesive-slathered hood. The front of the car will be such varied designs of tiny colorful glass beads
