Maker Faire Detroit 2012: The Autokineticons!

One of the best things about presenting at Maker Faire Detroit is that you basically get the run of the Henry Ford for three days, and get to poke around before the gates open and after they close. The conservator/mechanics at the Henry Ford are incredibly open and welcoming and enthusiastic about the machines they've restored and maintain--basically, they have the same attitude as the makers who've come to show off their projects.

So, for example, before the gates opened on Day 2--and thus before the crowds had poured in--I was wandering around looking for a pleasant bathroom when I came across the Henry Ford's all-original, fully functional 1922 Detroit Electric, which had just been moved outside to be displayed with some other groundbreaking early automobiles.

This picture doesn't really do the DE justice. It shows off the idiosyncratic back deck and the wonderful lines of the hood and fender, but can't capture how wonderfully the body and paint have been restored; it's smooth and so glossy it's almost luminous, like puddles of black and blue ink on a white marble counter. And that glass? That curved glass? That's *original*!

For those not in the know, I've included the official signage about this all-electric vehicle here. The Detroit Electric was often marketed as a "woman's car" because it eschewed the grease and oil and petrol and could be started at the push of the button, rather than risking a broken wrist trying to crankstart a gasoline engine. This I'd all heard before; what I didn't realize until the conservator pointed it out was that this "woman's car" notion had influenced the interior design, as well. Check this out:

Those two bars next to the driver's side door are the tiller steering (the longer bar folds down so that it's horizontal in front of the driver) and the throttle (the shorter bar--if you look at the sign above you'll see that there was actually a pretty interesting electromechanical system for varying speed and torque, because the car didn't have a conventional variable transmission as we think of it). None of that was so special. What I love is the *seating*: The Detroit Electric "opera coupe" was driven from the left rear seat, and the front right passenger seat swiveled so that all of the passengers could sit facing each other and chat. You know, for the ladies.

Here's another review of that swivel front passenger seat, which also gives a view of the left front passenger "jump seat."

Finally, two more shots of the exterior, for good measure:


During load-out on the final day I got to take an impromptu joyride in an 1885 Benz Motorwagen--totally on the basis of my yelling at the passing motorist "Hey! Gimme a ride in that!" (I didn't think he'd stop, because I didn't think he'd even hear me over the racket of that damn thing's crazy single-cylinder banger.)

The Benz was the first proper commercial automobile--in that it was actually built, top to bottom, to be a motorcar, and not just some crazy retrofit or barn-built one-off project. That said, it is still an absolutely *insane* vehicle to ride in. Because it was built to share the road with carriages and streetcars, you are really high up; it feels like you're racing down the lane perched on top of a step-ladder nailed to a wagon. Once again we see a crank-style tiller steering system, which makes sense historically, but feels totally nuts when you're riding shotgun and the driver has the hammer down and is weaving around a bunch of folks trying to load up their gear and get home as soon as possible. And check out the "engine compartment"--which is entirely open and includes hot things, exploding things, thrumming belts, and a roaring weighted flywheel. On the one hand, it's behind you, so it's not like you'll be pitched into that churning mass of combustion and gear-ratios on a hard stop. On the other hand, if you're a big goofus with a habit of draping his long arms behind the seat while riding in a car, you can loose a finger in a flash. Speaking of which, here's me looking like a total goofus on this lil slice of modern human history (all fingers intact):

Maker Faire Detroit: Boomerangs, Conference Bikes, Soldering, and Over-Priced Treats! (@chrissalzman @dgoings @nostarch @makerfaire)

Up to now I've focused mostly on the work end of Maker Faire Detroit, which sorta elides the fact that the point of doing the work is in order to get a chance to run around and check out the fruits of everyone *else's* labors. When we weren't wigging out with cigar boxes and guitar strings or spreading the water rocket love, we got to gawk and blather and climb a big huge geodesic dome and eat some pretty darn deliciously overpriced faire-food (Big props to whoever tossed $20 of food tickets into one of our boxes. I don't know if that was an unlikely wind-blown boon, or if someone surreptitiously helped him/herself to a copy of my book and elected to pay in meal tickets, but finding these in the middle of the first afternoon was a God send of ice-cream sandwiches, lemonades, and bottled waters.) Also, I finally got to ride the conference bike (*this exact conference bike,* although clearly none of those kids is me):

My booth at the Faire was directly adjacent to a table staffed by some students from the Henry Ford Academy, a small high school operated on the Henry Ford Museum campus (which is a pretty rad place to have a school; the older kids are out in some converted box cars in Greenfield Village and the first-year kids are tucked in behind the Dymaxion House in the museum itself). I spent a few days working with the kids last month, and they spent Maker Faire teaching folks to play Go, Tafl, Hex, and how to build cardboard boomerangs (a few pics below, once again courtesy of charming Chris Salzman):

Maker Faire Detroit 2012: Rocking Out on the Cheap! (@chrissalzman @dgoings @nostarch @makerfaire)

Aside from making scads of free water rockets with impressionable midwestern youths, our other big goal at Maker Faire Detroit this year was spreading the Gospel of Rocking Cheap Homebrew Electronic Instruments.

(Again, all photos here are courtesy of the gracious and talented Chris Salzman, who took *lots* more over the course of Maker Faire weekend; check 'em out!)

The $10 Electric Guitar and its Fuzztone effect (which, honest to God, can both be built for under $15 total) are consistent pleasers, and a persuasive argument on the side of "you don't need to drop much coin to rock the party"

We also had the fully-amplified Thunderdrum--which makes a crazy vocal reverb if you shout into the can. This little guy ran up out of nowhere, grabbed the can away from a guy who was playing it more conventionally, and *screamed* into it, which was just about the most hardcore thing I'd ever seen. He *rules!*

It was really, really a joy to share my enthusiasm for these instruments--which I really do love--and feel it reflected back and magnified by folks who, for the first time, were realizing "Hold up; I could make these things! I could make these things *better!*"

Expect a few more pics later this week!

Maker Faire Detroit 2012: Water Rockets! (@chrissalzman @dgoings @nostarch @makerfaire)

I was fortunate enough to have two excellent co-conspirators at Maker Faire Detroit this past weekend: Dylan Goings (who you'll see in many of the pictures I'll be posting over the next few days) and Chris Salzman (who you won't see, since he took the pictures--although you can see him here rocking the No Starch Press temporary tattoo). A chap could not ask for two better blokes with whom to make Maker Faire.

This week I'll post pics and anecdotes about our weekend, but in short: It was really goddamn rad! We made over 100 water rockets with kids, we spread the Gospel of Cheap Homebrew Instruments, we climbed up a big geodesic dome, we ate over-priced hotdogs, we rode crazy vehicles, we stayed hydrated, and no one got sunburned, lacerated, concussed, or contused on our watch. It was basically the 100% perfect weekend.

But, for right now, let's talk water rockets. (All these pics are courtesy of Chris. He rules!)

Our water rockets are as simple as possible: cork, tire stem, bike pump, bottle, water, *zooooom!* (learn to build one FOR FREE!)

Here's a little animation of a launch (that's Dylan helping with the trajectory):


Here's another go at it:

A Few Quick Pics from Maker Faire Detroit Today

We had an excellent day at Maker Faire Detroit! We even got a tent this year! And remembered to take food and water breaks!

Chris Salzman, Dylan Goings, and I made nearly 100 water rockets with kids (Chris and Dylan did the yeomen's share--they are like a two-man water-rocket education assembly line!), and we talked ourselves hoarse about simple synths, easy amps, $10 electric guitars, DIY games, and more--despite the terrible roar of this monstrous air-horn organ just a few dozen feet away.

Anyway, here are a fistful of pics from today (incidentally, I only shot the last one myself; that's Chris rocking the No Starch Press temporary tattoo. Check out those guns!) See you makers tomorrow; I'm talking in the Drive-in Theater at 11:30am, and at my booth right outside the Automotive Hall of Fame all day. Come by and launch a rocket with us!

Liz Arum's 2011 Workshops

I've meant to post this for ages, and it somehow kept slipping through the cracks. About a year ago Liz Arum (of Makerbot fame, at least for me) did a summertime DIY/making workshop with a bunch of kids and built a few projects from SnipBurn (as well as others). She posted a bunch of pics that warm the cockles of my heart:

(the rest are here)

As it turns out, Liz used 30-gauge winding wire for the pickups in those $10 Electric Guitars--significantly beefier than the 42-gauge I cal for in the book, and also significantly easier to find at RadioShack. This, obviously, takes many more windings than the 42-gauge design, but she reports that the sound is good. I've since talked to other SnipBurn makers who've likewise used these much thicker gauge wires and had good results, so I'm going to start experimenting with this cheaper/easier wire as I work on projects for my next book (which is all musical instruments). Stay tuned for more details on my findings.

FYI, if you've built something cool based on one of the projects in SnipBurn, then totally hit me with some links to pics, audio, or video; I'm happy to add it to the gallery and share your links.

The Flyest Single-String Electric Guitar I've Ever Seen

This is the diddley bow that Chris Lynas built last weekend, riffing off the "$10 Electric Guitar" in Snip, Burn, Solder, Shred (Project #13)--plus a sweet lil Dirt Cheap Amp (Project #12) to go with it:

And here it is in action:

I *love* this! Such a great fit for these lil hands!

Incidentally, Chris is one of several builders who have used a thicker gauge of wire to wind their pickups and still had good results. Quoth Chris:

I used 40 gauge wire because it was what I could find. Works ok and was easy to handle with 5yo assisting. In combination with the beefy magnet it's quite a hot pickup. Neck is ash (from past project), body from old pine shelf. Machine head and string cost about £4 total from local guitar shop. All other hardware from the bottom of the toolbox.

I.e., Chris stayed within the $10 budget, despite the strong pound sterling! Supercool!

Some folks may already be familiar with Chris Lynas from this project, where he 3D-printed new discs for an old-school Fisher-Price "record player" (which was actually technologically more of a music box):

(Worth checking out the link, as the code/CAD-based solution is pretty fascinating.)

*thx Chris!*

A Valentine's Day Sock Cthulhu

I received this email two days ago, but decided to sit on it so as not to inadvertently spoil any Valentine's surprises. Cirsten writes

Hi David: I found your sock Cthuhlu on ManMade and had to make it for my bf for Valentine's Day. Now I am a very crafty girl, but have never sewed anything in my entire life (27 years) but had to do it...so I am sending you the results. This vday sock monster was created in 4 hours (had to figure out how to sew it all together and find wire for the wings, used underwire from a bra lol)

Well hope you like and I made you proud.

Yes indeed! The underwire wing reinforcement is *genius*! And I *love* this fella's saucy little pose on the sofa:

Check out a couple other pics here (man, I *love* those wings!)

*thanks Cirsten!*

Boomerang Success Story!

Make A Simple Cardboard Boomerang | Apartment Therapy

I remember when my brother got a foam-rubber boomerang at the circus one year. We spent hours throwing it at each other in the backyard, desperately trying to get it to come back to us with little success. I figured I just didn't have the knack. As it turns out, it was the boomerang's fault (I knew it!), and I can make one in a few minutes that is guaranteed to work. Sign me up!

FACT: Hearing about folks' success with one of my projects is just *insanely* gratifying--and all the more so when it's a boomerang success story. My introduction to boomerangs as a kid was *also* a circus souvenir, and I had *exactly* the same experience as Richard; soured me on the damn things for ~15 years.

Do you have a boomerang success story? Send it my way; we need to push back against all the terrible boomerang karma drifting around out there.

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!*
