IEEE Spectrum has a short blurb about a very creative application of quadcopters. The videos are worth a look.

Arduino Interrupt presentation has been posted
I posted slides and code for the examples from the Arduino Interrupt presentation I did on Monday, September 8, 2014. There was discussion after the presentation on how to sleep for an hour or a day or … I added another example to show one way to simulate a long sleep with multiple 8 second WDT interrupts.

SPARKcon coming real soon now!
SPARKcon is an interdisciplinary creativity, art & design festival produced by the non-profit creativity incubator, Visual Art Exchange, in Raleigh NC. SPARKcon 2014 will be the 9th annual event and happens Sept. 11-14 in downtown Raleigh.
geekSPARK is a showcase for the creative use of new and interactive media and technology in the local community. Whether in the form of a large video game studio, or a solitary multidisciplinary genius, The Triangle is filled with people blending art with technology, creative ideas with technical know-how. Our goal is to bring more of these people together, and to provide a venue to promote their emerging work. There will also be 3D printers and other fun stuff.
Latest Amp Hour: SDR meets RADAR
This week on The Amp Hour Chris Gammel’s guests are Michael Ossman, the guy behind a (cheaper, simpler than previous, highly capable) software defined radio system and Greg Charvat, the guy behind a coffee can-based synthetic aperture radar system that uses your PC’s “sound card”. One of the most easy on the ears, friendly and interesting sharing between techies I’ve listened to in a good while. For those interested in learning about SDR Michael has started a tutorial series.
T-962 Reflow Oven Vent Setup and Editorial
This house used to have a wood stove in the basement and for years I’ve been using the vent to get coax to the roof-mounted TV antennas, but now it’s got a serious 240v fan jammed in it for a fully kludgephonic reflow oven vent.
Now I just need to find or make a fume hood that can properly handle the huge exhaust flow out the bottom of the oven when it’s in “cooling” mode. Whatever I end up with will be fully enclosed (maybe a plastic “flap” or door on the front) except for an inlet air arrangement that I haven’t thought through yet. Maybe holes in the table top below the oven and yet another vent hose that comes from “someplace” where I can get air so there’s little chance of fumes coming out that hose?
Please don’t leave a comment about masking tape inside the oven. It isn’t “tape fumes” I’m arranging to avoid.
