  • Another Reason to Beware Bargain Basement Bluetooth

    Another Reason to Beware Bargain Basement Bluetooth

    I was debugging a Bluetooth-related problem on a Windows 7 machine recently, and I found another great example of why sometimes you get what you pay for, even when buying something as nominally standardized and homogeneous as a Bluetooth adapter. It so happens that this machine was using one of these $5 adapters with the…

  • Failed Antenna Design 101

    Failed Antenna Design 101

    I just got some more Bluetooth dongles in from DealExtreme. This one advertises extended range and EDR support, for $5. The package looks convincing enough, nevermind the engrish: So I cracked it open, naturally. (Hey, I was planning on using it for that crazy project.) And I was shocked to find this:

  • New MacBook Pro + Fyre

    New MacBook Pro + Fyre

    Back when I bought my last Mac: USB and the Playstation 2 were new, Altivec and shiny plastic were in, and fans were almost starting to line up for the first Harry Potter movie. Oh, and warrantless wiretapping was still illegal. So, Apple, I guess it’s time to put all those hardware failures behind us…

  • Turbulence

    Turbulence

    For anyone who hasn’t already seen it, Linus Akesson (of Craft fame) just released his first demo for the Parallax Propeller: Turbulence. You can watch the high resolution video on capped.tv, with an introduction by Linus himself. Or, if you have a Propeller board, he’s provided binaries and source code. The demo is quite impressive,…

    Spark Fun in Fortune magazine

    Spark Fun Electronics is awesome. If you’re an electronics hobbyist who hasn’t heard of them, you’re missing out. While us hobbyists have long been able to get a huge variety of “reasonably” priced staple components from Digi-key, and crazy-cheap surplus components from places like All Electronics Corp. and B.G. Micro, I couldn’t help feeling like…

  • Moral dilemma…

    Lately I’ve been interested in e-textiles and fabric sensor technology. For an example of something I find infinitely fascinating, take a look at this DIY fabric bend sensor. (Via talk2myshirt, the best named blog evar.) In that project, many of the conductive textile materials were originally designed (or at least marketed) for electrostatic/electromagnetic shielding applications.…

  • The future of computer education

    I just stumbled upon a web site which still sells the Elenco Micro-Master MM-8000 Computer Training Kit, a state-of-the-art piece of educational hardware which includes an 8085 processor, 256 bytes of RAM, and a convenient set of keyswitches and LEDs for entering programs and inspecting memory. I remember seeing these in magazines like Electronics Now…

  • New oscilloscope!

    New oscilloscope!

    For a while now, I’ve been looking for a replacement for my ancient 50 MHz Hitachi analog scope. This scope has served me well for the 10+ years I’ve owned it, but it’s kind of a junker. Slow, out of calibration, flaky triggers… I’d could probably get a similar scope for about $15 on eBay.…

  • Propane pixels

    Propane pixels

    When I was little, I was afraid of fire. I had nightmares about being trapped in burning buildings. Pulse terrified me, even more so than It. I wasn’t scared of being burned- I had my share of encounters with a hot soldering iron or an overheated BJT. I was scared of fire’s power to consume…

  • If you thought USB sushi was odd…

    Okay, I just have to bloggy-blog about this work of genius that Christian found. My favorite has got to be the USB belt- the perfect gift for that lovable USB dork in your life.

  • Gimp 2.3.7

    I finally got around to installing the latest development release of Gimp, 2.3.7. It’s definitely worth a try. The menus have been rearranged a bit- a little disconcerting for a long-time Gimp user, but the new layout makes a lot of sense. It’s always nice to see the new splashscreens.. but I’m still a little…

  • Google Local on T-Mobile

    I was using Google Maps on my phone before it was cool. My little prototype Python application, Pyhole, still gets some use despite the fact that shortly after I got it working Google released their own Google Local Mobile. Why? Google’s client doesn’t work with T-Mobile. At all. Not to mention the cheap “t-zones” plan…

  • Random Update

    Random Update

    Well, it’s been a while since I’ve updated. Nothing on its own recently has inspired me much to write, but I have some smallish things to mention. I have a new laptop on the way! My 700 MHz Pentium III with 192MB of RAM was just getting too clunky for day-to-day use. I recently ordered…

  • January 2006 Update

    Fyre It’s easy for me to see Fyre as a ‘dead’ project these days- the existing codebase was declared ‘done’, and we moved on to a new architecture dubbed Fyre 2.0. In some ways this rewrite has suffered from second system effect, and the code hasn’t been touched in a while. But, I think we…

  • Metadata as personal information

    Hopefully all of you have seen this spiffy little tagging library that Christian and David are working on. One of the comments we hear about it is that tags should be system-wide, rather than per-user. Some people view tags as a global attribute of a file: much like a MIME type or its permissions. We…
