  1. A 3D printed laser cutter, aerosol solar cells, and reversing neural networks.

    09 January 2015

    3D printers are great for making things, including more of themselves. The first really accessible 3D printer, the RepRap was designed to be buildable from locally sourceable components - metal rods, bolds, screws, and wires, and the rest can be run off on another 3D printer. There is even a variant called the JunkStrap which, as the name implies, involves repurposing electromechanical junk for basic components. There are other useful shop tools which don't necessarily have open source equivalents, though, like laser cutters for precisely cutting, carving, and etching solid materials. Lasers are finicky beasts - they require lots of power, they …

  2. There will be a Mini-Maker Faire in Silver Spring, MD.

    15 September 2013

    I haven't seen this get a whole lot of love recently, so I thought I'd boost the signal in some small way.

    On Sunday, 29 September 2013 between 1200 and 1700 EST5EDT there will be a Mini Maker Faire in Silver Spring, Maryland. If you've never heard of Maker Faire, it's a series of events organized and thrown by Make Magazine that are collectively billed as the Greatest Show-and-Tell on Earth. At a Maker Faire you can see everything from 3d printing demonstrations to singing Tesla coils, combat robots to kite photography, and everything in between. Mini-Maker Faires are, as …

  3. HacDC at the USA Science and Engineering Festival.

    30 April 2012

    A week or two ago it was announced on one of the HacDC mailing lists that we'd been given a pair of tables at the second USA Science and Engineering Festival which was held this past weekend. It was a call to members who wanted to exhibit their work during the festival, and not a few of us threw our headgear into the ring. Rather than hold a Byzantium development sprint this weekend Sitwon, Haxwithaxe, and I met at HacDC to mass-produce demo CDs of Byzantium Linux to give out at our table along with the HacDC stickers, postcards, and …

  4. ContactCon 2011.

    26 October 2011

    As you've no doubt guessed, the reasons for my radio silence have been many and multi-layered, and now things have calmed down a little. I've been scrambling with the rest of the development team to get Project Byzantium in such a state that it was ready to show off at ContactCon. ContactCon, held late last week, was an unconference dedicated to showcasing and networking the developers of next-generation communication technologies that was driven by the attendees presenting their work rather than gathering to listen to people speak on stage. Most of us who attended are working on technologies that are …

  5. Radio silence: a sign of the times.

    16 August 2010

    I wish I could say it's been quiet over here, but it's actually been relentlessly busy for Lyssa and I down here in DC. I think I overextended myself a little the weekend of the prototype Spaceblimp launch, which left me fighting off... something.. that kept me at a high fever and feeling run down most of the time. I did a little detail working on my car to cover up the myriad scratches and scuffs that accumulate whenever you park for long periods of time in an urban area. While the speeding edge of an SUV door doesn't actually …

  6. Electronics projects to make you sit up and take notice.

    04 November 2009

    During my daily morning mainline injection of news on the Net this week, a couple of electronics projects caught my eye that I hadn't seen before. The first is a project from SparkFun Electronics that uses higher voltage than I'm used to working with - a Geiger counter kit with a USB interface. The kit is constructed around the popular ATmega 168 microcontroller, which means that the basic Arduino development kit can be used to write code that pulls samples from the Geiger-Muller tube (powered by a tiny high voltage power supply) and outputs numerical values over USB, where the 'counter …

  7. Life is so much more interesting when you don't get any REM sleep!

    17 September 2009

    It’s a sure sign that you’re trying to accomplish too much when you start forsaking sleep for other things. Lately, work has been running me ragged so to compensate I haven’t posted (or been writing) for a couple of days. To keep from overrunning myself I’ve been reworking a couple of electronics projects in my spare time and discovered in the process that the circuit diagrams I’ve been working from, simply put, won’t work as advertised. Thankfully, the principles they were supposedly based upon are sound so I broke out the data sheets and …
