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:
And here’s Dylan helping a kid through his first build: Drill, Ream, Insert Stem, Trim Cork, Load Bottle, Pump ‘er Up, Blast Off, *Joy!*
TUNE IN FOR MORE PICS TOMORROW!
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!
What’s Dave-o Doing at Maker Faire Detroit?
Maker Faire Detroit is this weekend! I’m going to be there with an outdoor booth all Saturday and Sunday, and also giving a talk indoors (apparently in a replica of a drive-in movie theater[?!?]) on Sunday at 11:30am.
What will I be *doing* all weekend?
I’ll be helping folks rock out on cheap-as-hell musical instruments like these:
I’ll also be building and launching free water rockets with kids of all ages (while supplies last):
And that talk at the faux drive-in theater? I’ll walk you through how to build a musical synthesizer for about ~$10 and play it with your mouth.
I’ll also have scads of swag from my publisher, No Starch Press. If you’re at Maker Faire and want to connect, the best way to contact me is via Twitter, where I am @SquiDaveo–or just find my booth and say “Hey!”
See you this weekend!
FREE SAMPLE: Build Quick-n-Easy Water Rockets
Project 20 from my book SNIP, BURN, SOLDER, SHRED is available for free over at the Art of Manliness:
Although store-bought water rockets were once an almost universal part of childhood (at least in suburban middle America, where I grew up), DIY water rockets are almost unheard of in the United States, despite being common in the United Kingdom. The key to the DIY water rocket is the ubiquitous plastic soda bottle. (Often called PET bottles in the UK, these are basically made of polyester, just like your favorite pantsuit.) A soda bottle can easily withstand 150 pounds of pressure per square inch—significantly more than a car or bike tire, and more than enough to launch it into flight.
The following design dispenses with many of the concerns regarding valves, firing mechanisms, pressurization, and so on, because the unit is impossible to over-pressurize, thus eliminating the risk of a rocket explosion. It’s quick and easy (no more than 5 minutes to construct), practically free, fun to make and launch with your kids (while teaching them some basic principles of physics), and, depending on the quality of your bike pump, can arc a bottle 30 feet at speeds safe enough to shoot at your pals, or send a rocket soaring a hundred feet skyward.…

Here’s what it all looks in time-lapse:
The Worst Speech I Ever Gave (@makerfaire)
The Worst Speech I ever gave was at the 2011 Maker Faire Detroit. I had an outdoor booth at the Faire, where I was making free upcycled water rockets with kids, showing off some of the projects from my book, and generally spreading the gospel of Making Something Rad Out of Rag and Bone. I’d subsequently been invited to give a talk about toys and the sorts of things that were in my book.
It was a 90/90 day in a week of 90/90 days, and because of a misunderstanding during registration, my booth had no shade apart from some stunted ornamental cherry trees. My primary assistant has basically the exact some species of social anxiety as I do–one that makes you a garrulous raconteur when you have an audience, but a total wreck in the solitary run-up to getting in *front* of that audience. Neither of us had any stomach for food, and subsequently had only brought a couple liters of warm water and a jar of cashews as rations. It was like we were on some misguided vision quest. I was slated to talk at 2pm, and by the time I made it onto the savagely refrigerated mini-stage in the Henry Ford museum, I had been standing in the blazing sun for seven unbroken hours and eaten about 200 calories.
My talk was set to run 30 minutes. I had a PowerPoint presentation that consisted of maybe six slides, one of which was an antique photography of a man riding a wall-of-death with a lion in his sidecar. I haven’t the foggiest what that image was intended to convey. The year before, in 2010, I’d given a small-scale presentation, but that was before the book was finished, and I’d ended up speaking in excruciating detail about the project I’d been working on at that time: electromagnetic pick-up design for cheap, easy, home-brew electric guitars (I mean “cheap”–under $10 in supplies–and I mean “easy”: It’s a 2 hour project at most, plus letting some glue dry overnight). This had actually gone over fairly well.
I was supposed to be talking about “toys” in 2011, but my conversations with the folks at MAKE had been sort of foggy in the run-up, and I’d decided I wanted to talk more generally about toys and toy making and why it’s a Good Idea to make toys out of junk with your kids. Meanwhile, a program was printed listing me as the author of such-and-such book, there to talk about toys. I did not see this program until I left the stage.
But, so, when I took the stage I was in front of about 40 people, many of them children. I was reeling from the sudden shock of AC; all I could think of was Shackelton abandoning his whiskey at the Pole. I had six slides, maybe, and although I’d written a book about making toys, and was spending two days making toys out in the fantastically beautiful Michigan summer, I wanted to talk about something abstract and neurosciencey and meta-analytic that occupied, literally, six sentences in the 340 page book that was my ticket on to that stage.
The speech was a disaster. I opened my mouth, got about halfway through my first name, and then a steam-engine power plant exhibit started up, a banshee wail that made it impossible for me to hear my own amplified voice, which was fine, because it also drove every thought from my brain.
Things went off the rails from there: I said the word “toys” at some point near the start, but then found myself in a fugue, talking about Henry Ford and Edison and the “Great Man” theory of history and cellphones. Audience members smiled faintly, in the manner of people slowly stepping away from a knife-wielding chimp. Five children in an Indian family in the third row fell asleep as their parents stared at me blankly, at least enjoying relief from the heat and the crowds. At one point–and bear in mind that I was here because I make super-kid-friendly water rockets out of old bottles and tire stems–I found myself talking about the Arab Spring. A bald white man with a droopy walrus mustache rose from his front-row seat and walked out. Crickets sang during the Q&A, I left the stage to polite not-booing, then almost passed out in a *very* ornate men’s room.
A few weeks ago I was retelling this anecdote to a group of friends who, clearly, I’d regaled with this tale enough times already. My dear friend Fritz Swanson interrupted me at the mustachioed-man-walkout to say “Yeah, yeah, we know, you activated a future domestic terrorist while giving a speech about toys. That guy’s gonna park a van in front of a federal building in a few years, and we’ll all know why. Good work.”
Anyway, if you want to see something akin to the things I was trying to say that day, check out my next column for the Ann Arbor Chronicle (UPDATE: Here’s the direct link to my latest column on education, Great Men, cell phones, picking fights, swapping innovations, and so on. ).
See you at Maker Faire Detroit this year! We’ll be making water rockets, rocking out on electric diddley bows, and learning to make synthesizers you shove in your mouth (maybe)!
Attention All Steampunks & Booknerds: All 111 Volumes(!!!) of Queen Victoria’s Diary Are Online NOW!
Free for your perusal until the end of July.
Queen Victoria’s Journals – Home Page
The interface is whack, but start browsing–almost at random–and you’ll find some startling and wonderful passages. To wit, this lil bit from page one of volume one, recounting one moment from Victoria’s 1832 journey to Wales via carriage:
This is the world that even the *richest little girl in all of the British Empire* saw and found remarkable, but by no means shocking or foreign. If you’re writing steampunk and this isn’t in there, then you’re doing it wrong.
See You at MAKER FAIRE DETROIT: JULY 28 & 29!
I’ll be at Maker Faire Detroit again this year, braving the searing rays of our terrible and merciless sun and shooting off water rockets like a mad man. I’ll have a “Cheap Thrills” booth outside, where I’ll be showing off under-$10-projects from SNIP, BURN, SOLDER, SHRED (as well as a couple of the new projects from my upcoming book of unconventional musical instruments), signing books, and making free water rockets with all comers (while supplies last). I’ll also be giving a half-hour, air-conditioned presentation on Sunday: “Your First Synthesizer: A Weird Little Noise-Toy You Can Build Tonight.”
My long-time co-conspirator Fritz Swanson will also be at Maker Faire (his first ever!) demoing “Letter-press Printing: Data Distribution the 19th Century Way,” as will my pal Amy Stevenson, teaching at-home artisanal paper making. See you there!
Reduced rate early-bird tickets are still available, or so I’m told (click through the Maker Faire Detroit link for details).
Make a Log into a Stove
This won’t come up often, but it’s one to keep in your vest pocket, just in case:
Stuff in some newspaper into the cracks as deep as you can get it, leaving a wick at the bottom, and light it up.
That’s all there is to it—the log burns from the inside out, and you have a simple, handmade stove….TA DA

My God, These Are Lovely Motorized Bicycles
The Derringer Bespoke Collection. — derringer
I don’t usually go in for the motor-assisted bicycle thing, but if I were to find a few grand lying in the street, I’d drop it on one of these in a heartbeat. (Well, first I’d pay my summer property taxes, so if I found a buncha grand lying in the street . . . well, you get it, you get it. Just saying’: Damn, these are *lovely!*)
Print-n-Snip Boomerang Template
This PDF includes templates for three boomerangs: a scaled down version of the quad-blade fast-catch boomerang in Snip, Burn, Solder, Shred, plus two new tri-bladers). Each fits on a single sheet of standard 8.5-by-11 paper (and, as a bonus, each of these designs scales pretty well; if you have access to a printer that can handle bigger paper, then you can scale these up and make bigger boomerangs).
To use the Print-n-Snip Boomerang Template:
- Print out the boomerang that catches your eye (slightly heavier paper—like resume stock—makes for a slightly easier to trace template)
- Trace the design onto light-weight cardboard (such as poster board, a cereal box, a Krispy Kreme donut box, etc.)
- Carefully cut it out
- Crimp the quarter-line on each blade (as described in step 7 of Project 18 in the book)
- Tune and throw!
If you come up with a boomerang design you like and want to add it to the template, drop me a line! (My email is in the “About the Author” box.)
