Cardboard tube battle

My local library picked up on the festive trend of Cardboard Tube Fighting. The Boston Globe covered the preparations:

The group discovered cardboard tube fighting last summer in time to incorporate a bit of it into a presentation on Greek mythology at a reading program party.

The weapons are cylindrical pieces of thick cardboard about 4 feet long. The appeal, explains young-adult librarian Ellen Snoeyenbos: "It's totally ridiculous.''

As word of mock combat with reliably harmless weaponry spread among the town's youthful warriors, Snoeyenbos and the Bookmarks seized on the fund-raiser as a chance to exploit their discovery of the fighting fad made popular by YouTube.

Saturday's event will feature one-on-one tournaments, guild-on-guild skirmishes (up to 10 fighters per team), "and an all-out battle for possession of the Royal Crown,'' according to the club.

They've gathered hundreds of tubes, and youth of all ages are uparmoring in a pulpy way.

Intern's Corner: Test-firing the HHO rocket

MAKE: Intern's Corner
Every other week, MAKE's awesome interns tell about the projects they're building in the Make: Labs, the trouble they've gotten into, and what they'll make next.

By Steven Lemos, engineering intern

Making the Hydrogen-Oxygen Bottle Rocket (that Adam Savage is posing with on the cover of the new MAKE, Volume 20) was a pretty basic endeavor, with the exception of the circuit. The original schematic diagram had a flaw in it, but only after we breadboarded the circuit -- twice -- did we catch it.

I guess that's the reason we MAKE interns build the projects that run in the magazine, so it's us who bang our heads against the table and not you. I will kindly take that cookie now.

The experience showed me that, sure, when working with electronics it's easy to misplace a component or wire, or completely miss something, which I already knew, but it's just as easy to have a diagram be the culprit. So a word to the wise (a word I'm sure all the experienced hobbyists have already discovered for themselves): if you take care when putting together these tedious circuits it will pay off, for if you can trust in your work, then you'll know the culprit lies in the plans, and you won't spend hours chasing that metaphorical wild goose.

Twice we breadboarded this bad boy before discovering an error in the schematic -- so you won''t have to.

But on to the actual launch. :) We had talked to the local electronics store owner, who at the time was making his own hydrogen using a more sophisticated apparatus, and who was interested in what we were doing with ours. So he came to watch, and brought along his professional pyrotechnician friend, who showed us how to make fuses with 12V and tiny resistors (basically the resistors pass so much current that the wire heats up and can act as a fuse to light stuff -- voilà, cheap fuses).

Our beautiful 2-stage HHO rocket ready for test launching -- before being crippled by a crash.

The first launch was a success, with the two stages going off rather quickly in succession, so we dialed in a little more delay time in the circuit before the stage 2 ignition. This was good and bad. We got more height out of the rocket on our second launch, but on its return it landed electronics side down. This resulted in our circuit behaving oddly.

So, not ready yet to call it a day, we began firing off only one stage at a time, adjusting the proportions of HHO (hydrogen and oxygen gases), water, and air, and testing the makeshift fuses, which worked fine for a single stage, but due to the time they take to ignite (3sec@12V) might not work for 2 stages.

We probably launched 12 times that day, attracting passersby. Good weather, new friends (who like blowing stuff up), and multiple launches. All in all, a good day. Houston, we have liftoff.

Make: Holiday Gift Guide 2009: Toys for grown-ups

I'm old (never you mind the hard number). But I'm still a kid at heart and I love toys. And I'm not talking about motorcycles and cars and speed boats, aka "grown-up toys," I'm talking model rockets, radio-controlled anything, little toy soldiers, and board games. TOYS! The cool thing about being an adult, and being into the toys of youth, is that you've got a lot more money in your piggy bank! In this, our first Make: Gift Guide 2009, we'll look at a few top of the line traditional toys, with an emphasis on toys you build, mod, and hack. Please share with us in the comments what sorts of cool toys you'd like to see under the Christmas tree or Hanukkah bush this year.

Initiator Rocketry Starter Kit (Aerotech, MSRP: $299/$172 at Tower Hobbies)
Most every grown up geek remembers being a young geekling and building and flying Estes Rockets. If you haven't been paying attention, you may not know that hobby rockets have been growing, in power and size, ever since. And growing, and growing, and growing. Motors are designated in nearly every letter of the alphabet now (and each lettered motor is twice as powerful as the previous-lettered motor) and some rockets require teams to build them (and heft them to the launch tower -- and it's a tower, not a rod). AeroTech is one of the leading manufacturers of hobby rocket motors. Their Initiator Rocketry Starter Kit will launch you into this very grown-up hobby (where your credit card bills may get equally astronomical). The kit includes a launch system and a 3' 9" rocket that can handle motors E thru G. This starter kit usually costs $230 (w/ one motor), but Tower Hobbies has it for $172 (w/ no motors). Motors will cost you about under $20 each.

Novus CP Nano Sized 2.4GHz RTF Helicopter (Heli-Max, $220)
R/C cars, planes, and helicopters keep getting more sophisticated and more "real" by the year. Just as hobby rockets keep getting bigger, more powerful, and are closing in on the smaller, cheaper, faster bottom-end of commercial and governmental rocketry, hobby R/C is starting to look not that different from man-portable recon systems used in the military. In fact, that line has already been largely erased. New technologies and economies of scale are also allowing extremely sophisticated R/C vehicles to be offered at really affordable prices, such as with the Novus line of "nano-sized" helicopters.This Novus CP model shown here is actually the top of that line and capable of some pretty amazing aerobatics. Several cheaper models are also available, for as low as $125.

FPV Flying Systems
Long Range Ready to Fly FPV System (ReadyMadeRC, $4,500)
One of the more amazing things to come out of the R/C flying (and driving) world is FPV (First Person View) systems which use tiny cameras in the cockpits of model planes and wireless transmitters and receivers to send point-of-view video to a video monitor, or even a virtual reality-type head-mounted display, on the ground. This allows you to fly the plane like you're in the cockpit. Some FPV hobbyists have gone so far as to put instrument panels in the cockpits, displaying real-time flight information, so that you feel as if you're really flying the plane. With the VR rigs, when you move your head, the camera's POV moves with you. As you can imagine, this is not a cheap hobby to get into. You're adding wireless color video and virtual reality equipment on top of radio-controlled flying gear. The above $4,500 system, from ReadyMadeRC, includes the plane, the R/C gear, the FPV set-up, and everything else -- it comes ready to fly. FPVPilot is a great place to start exploring the FPV hobby.

Compound Oil Immersion Microscope 163 (Maker Shed, $820)
While most of the items in our guide are toys, not tools, we couldn't resist drooling over the new microscopes in the Maker Shed. I had two scopes as a kid, and had the greatest time exploring unseen worlds by peering through their eyepieces. This top-of-the-line microscope is trinocular. It has a third eyepiece so that you can attach a still or video camera to capture what you're seeing through the binocular eyepiece. This is a laboratory-grade microscope, with surprising features and high mechanical and optical qualities, at a hobbyist's price. Note that the other reason we have it in this gift guide is that you need to order the microscopes by December 3 to guarantee Christmas delivery. If you'd like some advice on what scope to choose, check out our "Choosing a Microscope" article in the Make: Science Room.

Gakken Kits
When I was a kid, model kits from Japan had an intense allure. They seemed (okay, they generally were) of much higher quality than American kits, and the instructions just looked so dang cool! Age has not diminished this impression and the popularity of the Gakken kits we carry in the Maker Shed prove that lots of people feel the same. These are unique and gorgeous kits that any tech enthusiast and kit-builder on your list will be thrilled to get. Above are the Sterling Engine Kit ($120) and the Vacuum Tube Radio Kit ($100, currently on sale for $86). The Gakken range is wide, from mechanical centipedes to tea-serving robots to retro 4-bit computers. See all the kits here.

STEM resources for teachers

This weekend I had an opportunity to attend a renewable energy workshop organized by the Southeastern Massachusetts Achievement and Retention in Technology group at Bristol Community College. The morning was packed with teachers sharing their lesson and unit ideas on ideas based around the STEM subjects of green technologies and energy.

The college offers a Lending Lab for tools and lab equipment that most schools are unlikely to stock. Through using these equipment resources, teachers can get their students' hands onto enough materials to for a series of lessons on windmill design, hydrogen cars, air purity testing, and more. Teachers shared their experiences in bringing this equipment into their classes and how it affected student learning.

The NEED Project was a new one to me, focusing on bringing the ideas of energy systems to the classroom. Their site has an extensive collection of materials organized by grade level that are ready to implement in the classroom, from background information to student handouts. Chuck Lawrence of Upper Cape Regional Technical High School shared his experiences of having his students evaluate the energy use of educational spaces in the school, and has encouraged his students to help their families understand their use of energy from environmental and financial perspectives.

Be a counselor at Space Camp

In high school and college, I was a camp counselor almost every summer, and I highly recommend it! It's such a rewarding experience and you make so many lifelong friends. So when I found out (from CRAFT's Rachel Hobson) that they're looking for counselors for Space Camp, I had to share. So many makers would make fantastic counselors!

The Space Camp mission is to use the excitement of the U.S. space program to stimulate young people's interests in the study of math, science, technology, and aviation. These immersive programs place students in a real world context allowing them to view math and science as something more than just an academic exercise- allowing them to recognize these subjects as tools to develop future careers as scientists, engineers, teachers, astronauts, and pilots. By combining cutting edge technology with hands on learning our counselors inspire young men and women to dream big and to work hard to make those dreams a reality.

"Letters, we get letters..."

Mark Frauenfelder and Dan Woods got sent this letter about the latest issue of MAKE, Volume 20. We got the sender's permission to post it here:

Mark and Dan,

This is Jim Kelly, the freelance tech writer in Atlanta. Hope you guys are doing well.

Just wanted to write and tell you how impressed and inspired I am with issue 20 of MAKE magazine. The interview (and foreword) with Adam Savage was extremely fun to read. As a father of a 2.5 year old, I too am anxious to encourage my son to explore, take apart, design, and enjoy the creative process.

Issue 20 was directed at kids, and I think you hit the bullseye, with force behind it. I hope this issue is one of your bestselling ones, and I for one am encouraging parents I know to pick up a copy. I'm also purchasing a few extra copies for some teachers I know.

My son just got done watching me configure my new CNC machine to mill out some fun designs on wood; his eyes could not have opened any wider. I wish all kids could have access to this level of technology and machinery, but unfortunately, our school systems seem to be cutting shop class and art projects and focusing time and money on standardized test-taking skills... how unfortunate.

To bring this all home, I guess what I'm trying to say is that there is such a demand for material/content that encourages our youth that a void has been created and cannot be filled fast enough. MAKE is in a unique spot to develop something that goes a little beyond the Maker Shed and the quarterly magazine. Maybe it's a subscription-based activity website, with monthly special projects broken down into categories such as "Do It Yourself" (no parents required), "Dad and Me" (or "Mom and Me" - projects with the parents), and more. Maybe it's a special magazine (like your Halloween special issue) that focuses on even more kid-friendly content. Or maybe a mixture of projects and inspirational interviews (Dean Kamen comes to mind) in a book format.

I'll wrap this up by saying that I, Jim Kelly, hate the three month wait between issues of MAKE... I read every issue over and over again. I'm starved for this type of content. And I'm an adult - imagine what those kids who have this creative streak inside them must feel? They're in need of something... not sure what... and maybe you guys can figure out what to offer them. Issue 20 could easily be just the tip of the iceberg.

Take care,

Jim Kelly

Thanks for your thoughts and kind words, Jim. Reaching the educational market, be it home-schooling parents or teachers in grade school and college, is an increasing focus of ours. We see the new Make: Science Room as part of that effort. We also have the Make: Education social network to reach out to educators and and to create a place where they can network with each other. We've also been working on a dynamic new project-based program of making and mentoring designed to raise the next generation of makers. We're developing this with some very innovative, high-profile partners and are very excited about the prospects. Stay tuned -- we'll be making an announcement about this in the next few months and looking for some kids to participate in a pilot program.

We'd also like to point out that there is something to tide maker parents, kids, and educators over between issues of the magazine: this website, Make: Online! Over the past year, we've been adding much more original content, regular columns, weekly projects, guest authors, and special programs. And then there are our regular Weekend Project podcasts, and special videos, like Collin Cunningham's MAKE Presents series, and Marc de Vinck's how-to and kit build videos. There's a lot going on here, so we hope you're getting your daily dose of MAKE from us. If there's anything else you'd like to see us do here to satisfy your MAKE fix, please let us know. We're always looking for ways to expand and improve the site.

Where are they now: Pleo the Dinosaur

He's baaaaacck! Pleo, the long-hyped, short-lived robotic baby dino is back on the market. Robert Oschler, of RobotsRule, has posted a piece, The Inside Story Behind Pleo's Rise, Fall, and Resurrection, that includes an interview with Derek Dotson, one of the founders of Ugobe, and now the CEO of Innvo Labs, the company that acquired the rights to Pleo.

RO: Are there plans for any new accessories or new Pleo models?

DD: I can talk about the 2010 Pleo model. That model will look the same as Pleo does now except it will have a new paint job and eye color to differentiate it from the current Pleos. Over the coming year we intend to give Pleo more depth to his personality and utilize the sensors better. For example, Pleo doesn't do a whole lot with the camera in his nose right now. It's not the hardware since the camera is a good quality camera. However there's a lot of room for improvement in the software. An example of a specific feature people want badly is getting Pleo to come to you. The 2010 model will do that. Also, Pleo uses power more efficiently which will lead to longer play times. To make Pleo more realistic, Pleo will develop certain character biases at birth so that everyone's Pleo will be different. As for the sensors, the reason why they are currently underutilized is due to a bottleneck in the serial bus that connects them to Pleo's processor resources. That's something we can fix without drastically altering Pleo's architecture. Once that happens, we can do more with them when it comes to Pleo's hearing, vision, etc. Beyond 2010 there will certainly be new creatures other than baby robot dinosaurs.

From MAKE magazine:

Fake TV camera trend takes over elementary school

This fascinating piece, from This American Life (animated by Chris Ware), tells the story of an elementary school where a couple of kids made a TV camera out of cardboard and tempera paint. Soon, the cardboard camera craze went viral and it seemed like every kid was either a camera operator, an anchor, or some other faux TV production person. Then things went positively post-modern.

Drill-powered "fort" speakers

MAKE subscriber John Kelbley was doing some expansion/improvements on his kids' "fort" and wanted to deliver music to the (unpowered) space. His solution was to use the rechargeable powerpack from an an old 12 volt Ryobi drill and use the drill body as a stand for two outdoor speakers he found on clearance. Amplification is provided by a Sonic Impact T-Amp he cased inside the gutted drill body. Love the volume control where the drill chuck used to be.

The Best Sounding Drill I've Ever Owned!

Decade of homemade kid costumes

For years I didn't consider myself very creative. Sure, I always decorated the house for holidays, did crafty projects with my kids, refinished furniture, loved to try new recipes, and shunned store-bought costumes for what I think are way better homemade creations, but a crafter? Not really.

These days I'm trying to convince myself that I am indeed a crafter. And when you're surrounded by knitters, crocheters, professional seamstresses, painters, and soft-circuit mavens, you need lots of convincing! I recently went back through photos of the kids in their Halloween costumes that I've made, and gosh darn it, I am a crafter (of sorts). Enjoy the photos after the jump!

PS: Two of the costumes shown were store-bought, or mostly purchased at a store and then embellished with homey touches.See if you can spot them. And one of the boys is a former intern, not one of my kids, exactly.
