Unaltered Footage of the Wave-forms in a Jazzer’s Bass String

Very cool footage if you are interested in how string instruments work. This is straight video, unaltered and not CGI: The interaction of the digital video camera light-sensor’s scanning speed, the frequency of the string, and the frame-rate of the video make the standing s-wave in the bass string visible. (This is called a “rolling shutter” effect, and there are lots of cool examples floating around the internet. Wicked-awesome!)

Supercool LEGO Technic projects

LEGO Technic Idea Book Complete Set | No Starch Press

This is rom Yoshihito Isogawa’s book Wheeled Wonders.

I have a copy of his Fantastic Contraptions that my publisher sent me, and I *love* it: Really beautiful book (it’s all color photos of the projects, rotated and exploded so you can see how they piece together and function), lots of whimsical projects that are complex without being complicated. (His other videos are pretty sweet, too.)

  • Make Puppets with Jim Henson

    Making Puppets With Jim Henson @Craftzine.com blog

    This is a good intro to puppet-making, and a really solid lesson in pedagogy.
    I love how chill Henson is; he doesn’t dumb down what he’s saying, and he also doesn’t amp it up (*HEY KIDS!*)–he presumes that his audience, regardless of age, is composed of interested human beings of average intelligence. It’s fun and it’s dignified (not in the sense of “stuffy,” but in that it respects the dignity of both the teacher and the student); in my experience, this is the best recipe for running a class where folks have fun and learn/make something they’ll value (again, regardless of age: 4-year-olds and 40-year-olds can all be spoken to basically the same way, you just have to squat on your haunches when addressing the former, and stand up straight when talking to the latter).
    I also love that the puppeteers are clearly messing with Henson. That cracks me up.

    FREE SAMPLE: Build, tune, and throw cardboard boomerangs

    Learn to make, tune, throw, and catch two different cardboard boomerangs in this FREE SAMPLE from Snip, Burn, Solder, Shred:

     

    PROJECT 18: Cardboard Boomerangs

    Generations of American children wrongly grow to believe that building and throwing boomerangs is very difficult. This flies in the face of reason: Using less-than-ideal materials, human beings have been building, throwing, and catching returning boomerangs for more than 11,600 years. . . . They are, in fact, among humanity’s longest-standing ways of showing off. . . .

    Boomerangs are absurdly easy to make; the real trick is in tuning and throwing them (all of which I cover in detail in this free sample). With the aid of the Print-n-Snip Templates (link below; includes two new tri-blade designs!) this is a great all-ages project: I’ve had a blast running boomerang workshops with teens and adults at sci-fi conventions, middle-aged family guys drinking beer, and dozens of elementary schoolers on the verge of Snow Day Insanity.

    My Favorite Sock Cthulhu Yet!


    ink spot: Sock Cthulhu
    Dear friend Corey Johnson made several improvements when building her Sock Cthulhu, all of which I heartily endorse. I *love* these wings! Check the link for details on her mods.

    If you make a sock monster–or anything else–feel free to drop me links, and I’ll add ’em to the gallery.
    *Thanks Corey!*

    What’d I do this weekend?

    Busy weekend! On Friday I gave an hour-long webcast, walking folks through building their own $10 Electric Guitars (Project 13 in Snip, Burn, Solder, Shred) and on Saturday morning I was interviewed during the second half of GeekSpeak on KUSP radio (central-coast CA).
    The folks at O’Reilly Publishing, who hosted the
    Webcast: A Stick, Some Wire, A Can, and Some Wax: The $10 Electric Guitar, have made video of the whole hour available on YouTube (embedded below). Combine that with this PDF of the PowerPoint presentation (including nice sharp versions of all the charts and diagrams), and you’re ready to build your one-string axe. Get to it! If you need some 42-gauge winding wire, I can help you out.

    As for the GeekSpeak appearance, you can check out the details here: Show for February 12, 2011 – GeekSpeak–or download the full hour of audio directly (I come in around the half-way mark; you’ll get to hear me blather, make weird yummy-noises-of-agreement, quote a +20-year-old Eddie Murphy routine, cough loudly into the mic, and wail on the $10 electric guitar through the Two-Transistor Fuzztone).
    REMINDER: In about a week (Feb 22) I’ll be doing a two-hour all-ages cardboard boomerang workshop at the Ann Arbor District Library Downtown Branch! See you there OR ELSE!

    FREE ONLINE EVENT: “A Stick, Some Wire, A Can, and Some Wax: The $10 Electric Guitar”

    The good folks at O’Reilly Media are hosting an hour-long webcast where I’ll walk folks through building their very own $10 Electric Guitars (Project 13 in my book Snip, Burn, Solder, Shred: Seriously Geeky Stuff to Make with Your Kids)

  • WHEN: Friday, February 11, 2011 @ 10am Pacific Time, San Francisco (or, for me 1pm, Eastern Time, in Michigan–for you, who knows?)
  • DETAILS or to SIGN UP: Webcast: A Stick, Some Wire, A Can, and Some Wax: The $10 Electric Guitar
  • COST: FREE!!!
    BONUS MICHIGAN EVENT: I’ll be running another cardboard boomerang workshop at the Main Branch of the Ann Arbor District Library on February 22 from 1pm to 3pm. Learn to build, tune, and throw cardboard boomerangs. Middle-school-age and younger kids are welcome with their folks. This one is also FREE!

  • Custom Steel Bikes: It’s All In the Jigs

    FROM STEEL: The Making of a Soulcraft on Vimeo

    FROM STEEL: The Making of a Soulcraft from michael evans on Vimeo.

    Mike Kessler (carpenter and founder of the Workantile Exchange–which is where I sit and type most days) points out:

    Making the frame looks like the easy part: setting up the shop and building all of the specialized jigs before the frame is built, that is the hard part. The quality of a craftsman is in the ingenuity of his jigs– that is what determines the quality and consistency of the final product; this guy is impressive.
