MakeShift 19 deadline November 20th

The deadline for submitting your solution to the MakeShift challenge from MAKE Volume 19 is fast approaching. Napping in an ocean kayak is generally never a good idea, but what would you do if you stuck in this predicament? Work your brain, get creative, and win stuff! Here's the MakeShift in its entirety:

The Scenario: You're an experienced and avid open-ocean kayaker, setting off early from your favorite coastal launch point for a restorative and invigorating day on the water. You've checked with the Weather Channel and the National Weather Service, and both have predicted sunny weather, slight clouds, and virtually no wind. So, after donning some sunblock and checking your gear and supplies, you're off.

The launching goes OK, but you take on a little water fighting the breakers. When you finally clear them, you paddle steadily until you're about 1 mile offshore, which you confirm with your GPS. Venturing out a little farther, you paddle parallel to the shore for a few hours. Then, adjusting your life vest and seat cushion to make yourself more comfortable, you stop to relax and enjoy the scenery, but between the warm sunshine, the gentle roll of the ocean, and the hypnotically reflective water, you nod off.

The Challenge: When you wake several hours later, the ocean is choppy and a strong, southerly wind has picked up, which has pushed you at least 3 miles from shore and continues to grow in strength. You dig for your cellphone just in case you need to call for help, only to discover that the saltwater you took on earlier has rendered it useless. You paddle hard for shore, but even after a relentless hour, the winds and currents seem to erase all your progress and the tall beachfront hotels are becoming mere dots on the horizon. You realize more paddling might be fruitless and only exhaust you completely. So what do you do now?

What You've Got: Two gallons of fresh drinking water and a basic survival kit with a compass, a lightweight 6×7-foot survival blanket (silvered on one side and dark on the other, in a pouch), heavy-duty nylon tape, and a coil of thin but strong nylon rope. You've also got a Swiss Army knife (or similar tool), some marine binoculars, a GPS unit, your waterlogged cellphone, some basic medical supplies in their own self-contained marine emergency medical kit, and an extra paddle. You also have a lightweight, waterproof windbreaker and some foul-weather gear stashed in the small but useful front storage compartment.

To Enter: Send a detailed description of your MakeShift solution with sketches and/or photos to makeshift@makezine.com by Nov. 20, 2009. If duplicate solutions are submitted, the winner will be determined by the quality of the explanation and presentation. The most plausible and most creative solutions will each win a MAKE T-shirt and a MAKE Pocket Ref. Think positive and include your shirt size and contact information with your solution. Good luck!

How to build a catapult part 3 - Hollywood inspirations

Bill Gurstelle is your MAKEcation counselor for the make-a-trebuchet Family Challenge. Build a trebuchet and post pictures tagged "MAKEcation" in the MAKE Flickr pool to enter to win a $100 Maker Shed gift certificate!

Has anyone else noticed a lot of movies with trebuchets and other catapults in them? I sure have. For instance, they were the special-effects stars in the Lord of the Rings trilogy, particularly, the Return of the King. They've been on TV as well: Fox Sports, the Simpsons, Northern Exposure, PBS Nova, Warner Brother's cartoons and probably many others.

I built a fairly large and historically accurate trebuchet a couple of years ago. I named it Ludgar, the Warwolf, after the huge trebuchet built by Edward I of England in 1304. Ludgar was really big, accounts say that Edward cut down an entire forest to obtain enough wood.

Here's my list, admittedly incomplete. If you've got more, send 'em to me.

Chronicles of Narnia
Night at the Museum
Kingdom of Heaven
Alexander
King Arthur
LOTR Return of the King
Gladiator
Monty Python and the Holy Grail (I especially like the part of this movie where John Cleese says "Fetchez la vaca" in a cheesy French accent.)
Robin Hood Prince of Thieves
Robin and Marian
Robin Hood Men in Tights
The Scorpion King
Flesh and Blood (the Rose)
Jabberwocky
Army of Darkness
Timeline
Young Einstein
Willow
Star Wars #6
Richie Rich
The Messenger
Excalibur
Joan of Arc
Troy
El Cid

Timeline was a so so movie but the trebuchet is wonderful. Kingdom of Heaven and Gladiator have excellent battle sequences with catapults. The LOTR movies have well done CGI trebuchets.

How to build a catapult part 2: triggers and releases

More in my series of posts on How to Build a Catapult. In this post, I discuss Catapults, Ballistas, Trebuchets and the Triggers, Releases, and Latches that operate them.

I receive quite a few inquiries about making catapults and trebuchets. And among the most frequent questions is: how do I build the trigger? It's an important question.

Catapults are fun and educational to build and operate. When building a catapult, trebuchet, ballista, mangonel, or any of the hundred names by which such hurling machines are known, you'll find out that the mechanism that releases the throwing arm is often the most complicated part of the machine.

You may build your own release, which is tricky because you need to design the latch so that it will release reliably under full load. Actually, you can get pretty creative about triggers.

But considering how cheap and easy it is to buy one, it might make more sense to use one of the commercial solutions below, and spend your time working on the other aspects of the machine.I've spent time researching the best triggers and releases for small catapults. There are three good, off-the-shelf solutions: The archer's arrow release, the sailor's pelican hook, and the horse trainer's panic snap.

Archer's Arrow Release:

This is the premier solution. Works dependably, quickly and very smoothly. It costs a bit more, but of all the catapult releases I've tried, I like this one the best. Find it at a sporting goods store with an archery department, or find it online.

Sailor's Pelican Hook:

This is another excellent hurling machine trigger. Its normal use is in sailing, where it is used to securely hold and release lines and ropes. Basically a pelican hook is a hinged hook that can be quickly secured or released by a sliding ring. It is quite a bit less expensive than an arrow release, but it holds securely under load. The downside is that they can be awkward to release sometimes. Find it at a boating store or online.

Horse Trainer's Panic Snap:

A panic snap is a mechanism often used between a lead and a horse's harness. They are decent catapult triggers because they can be disconnected under load. A panic snap is specially built so that the latching mechanism is separate from the load bearing structure. Just pull back on the latch and the load releases. Very inexpensive, but not as smooth or dependable as the arrow release. Find it at a tack shop or online.

How to build a catapult part 1

Catapults are wonderful, exciting examples of technology. (I use the catapult to mean any projectile hurling device of ancient descent. Such devices may use springs, counterweights, or human energy.) They are simple yet complex; delicate yet brutal. Unlike looking at say your computer or an airliner, you can pretty much look at a trebuchet or ballista and kind of understand what's going on. On the other hand, the physics and kinematics are complex and intricate.

Tips for building a catapults:

Purity of concept aside, it pays to use modern materials. While it might be cool to build a coiled rope torsion spring like the ancient Greeks, you'll probably find it difficult to get enough spring power without torquing down the ropes so much that you'll crush the frame., Experiment with the use of bungee cords if you build a torsion or tension spring powered model.
I find hardwoods and metal frames work better than softwoods. Practically speaking though, dimensional lumber is what most people wind up using. Overbuild if you can, doubling up the wooden frame pieces. You'll be glad you did.
If you're making a gravity powered trebuchet, consider forgoing the pouch on the sling and simply attach a cord to the object you're hurling:. That way, when the projectile flies, then so does the cord. I call that "a sacrificial sling." It's way, way easier.
Consider your release mechanism carefully. For bigger catapults, consider a pelican hook (it's a peice of hardware that sailors use, and you get them at stores that cater to boating) or possible an archer's arrow release. You get those at sporting goods stores. Their fairly cheap and they work well with smaller machines. Much more info on catapult triggers in a forthcoming post.

There's a lot of historical information and plans for many sorts of catapults in my book, The Art of the Catapult which is on sale at the Maker Shed.

MakeShift 17 deadline this Friday

Mountain Bike Rescue

This Friday, May 22nd, is the deadline for the MakeShift challenge that appeared in MAKE, Volume 17. To enter, send a detailed description of your MakeShift solution with sketches and/or photos to makeshift@makezine.com.
Here's the challenge:

The Scenario: You and your best friend, both experienced mountain bikers, take off on a daylong jaunt to explore a little-known and rocky canyon trail. The ride is challenging but spectacular until, as you finally decide to turn around and head back, your friend's bike hits a loose rock, skids out from under him, and they both topple off the edge of the trail down into the canyon. Smashing his knee in the fall, your friend manages to land on a thin, unstable ledge about 15 feet straight down from the trail, only able to keep himself from falling farther by grabbing onto a small but secure tree branch jutting out from the rock, while his bike cartwheels out of sight to the bottom of the canyon.

The Challenge: Your friend is clearly in a lot of pain and there's no telling how long the ledge he's on will hold, so riding the many miles out to the trailhead to call for outside help is not an option. And, as is always the case in these situations, your cellphone gets no signal out here. Bottom line, you need to figure out a way to get your friend, who weighs a good 30 pounds more than you, up off that ledge and back down the trail to your car before nightfall -- which is maybe four or so hours off.

What You Have: In addition to your bike, you've got your daypack, which contains a canteen of water, some protein bars, a basic bicycle repair tool kit, an extra inner tube, your Swiss Army knife or Leatherman tool, a strong, flexible, 3-foot wire saw with split-ring finger-handles on both ends, some waterproof matches, and roughly 30 feet of strong nylon cord you use to tie your bikes onto the car. Since you know from experience that you can't predict the weather, you also have some waterproof nylon rain gear and a warm jacket.

There are some small trees on the upper side of the trail but none immediately adjacent to the ledge where your friend fell. Though he's conscious, it's best to assume he can do very little to assist you in getting him off the ledge below, and he certainly won't be able to walk if and when you do. However, he does have enough strength in his arms to hang onto the tree branch, at least for now. So what are you going to do?

If duplicate solutions are submitted, the winner will be determined by the quality of the explanation and presentation. The most plausible and most creative solutions will each win a MAKE T-shirt and a MAKE Pocket Ref. Think positive and include your shirt size and contact information with your solution. Good luck!

MakeShift 16 Deadline

Today's the deadline for the latest MakeShift challenge, which graced the pages of MAKE, Volume 16. But since I forgot to remind you readers about the deadline, we're extending the deadline by 1 day, to Saturday, March 7 (tomorrow!).

Here's what you're up against:

Tick, Tick, Tick ...
The Scenario: You've worked late into the night as a computer engineer in the high-rise headquarters of an international bank, and you're finally heading with your briefcase to your car in the subterranean parking garage. Your car is the only one left on this dimly lit level, parked along a cement wall right near the elevator. But, as you pull out your keys and are about to hit the unlock button, you hear a loud beep behind you.
Startled, you turn to see an object against the wall just a few feet away with a pulsing red light on it -- and in the poor light, you can immediately make out an illuminated timer which is now ticking off the seconds from a 3-minute window!
There is a jumble of multicolored wires, and an array of three motion detectors set to cover a 180º field off the wall, all of which are wired into a small black box sitting on a large brick-shaped object that's slightly smaller than a shoebox. Also atop the brick and on its ends, you see three horizontal glass tubes that appear to contain mercury with wires at both ends, as well as a metallic-looking cylinder with several long wires jammed into the side of the brick-like mass. There's little doubt left in your mind now that this is a bomb! -- and your arrival here must've set off the timer.
The Challenge: Though you know how mercury switches work, you're uncertain of the purpose of the motion detectors, or of the black box -- could it contain a hidden transponder? If you try to move out of range or call for help with your cellphone, might your attempt to flee or the cellphone signal set the device off? Hell, even pushing the unlock button on your key ring now could send the wrong kind of signal, no? But panic is not an option, as it seems you have less than three minutes to decide your best course of action. So what are you going to do?!
What You Have: Your briefcase and pockets contain what a computer engineer might normally have, within reason -- if that includes a Swiss Army knife or Leatherman tool, so be it. Beyond that, your brain is the best tool you've got. So think fast, and ... good luck.

Send a detailed description of your MakeShift solution with sketches and/or photos to makeshift@makezine.com by March 7, 2009. If duplicate solutions are submitted, the winner will be determined by the quality of the explanation and presentation. The most plausible and most creative solutions will each win a MAKE T-shirt and a MAKE Pocket Ref. Think positive and include your shirt size and contact information with your solution. Good luck!

Make 858
The creator of MacGyver challenges you to retrieve your keys from the bottom of a 15-foot crevice in the desert.
The Scenario:
Thinking you could use a new hobby to get you off the couch, your significant other gifts you with a metal detector for Christmas. After digging up loose change in your backyard and at the beach for a few weekends, you decide it's time for a real prospecting adventure. So, after loading up your SUV with the metal detector, a pick, a shovel, pry bar, and enough snacks and water for the day, you both drive 80 miles out into the desert to poke around some abandoned gold mines you've heard about.

Finally reaching the end of the road in the middle of nowhere, you ask your partner to unload the car while you head for the rocks to survey the landscape. But as you climb through some old barbed-wire fencing to look for a trail, your keys - attached to your Swiss Army knife - fall out of your pocket and skitter off across the rocks before they disappear into a deep, six-inch-wide crevice between two boulders. (Don't you just hate when that happens?) Needess to say, neither your cellphone nor your OnStar system gets reception out here, and the fancy anti-theft option you went for makes hot-wiring your SUV all but impossible.

The Challenge:
Without transportation, you're stranded. To avoid the daunting prospect of walking back out to the main road - as well as "never hearing the end of this" from your mate - you're going to need to recover those keys.

The boulders are too massive to be moved in any way and you don't have a direct sight line to your keys. But you are able to ascertain that the depth of the narow crevice can't be more than 15 feet. It's about noon now, so you've got at least 6-7 hours of daylight to work with before it gets dark. Surely someone with your skills and ingenuity can get those suckers out of there in time to get you home safely, if not still salvage the outing, no? As the wheels start turning, your mate appears and asks, "Is something wrong, honey?"

Here's what you've got:
In addition to everything mentioned, there's a basic tool kit in the car: hammer, screwdriver, adjustable wrench, snippers, pliers, etc., as well as 100 feet of nylon rope. Because this is an old mining area, there may also be some small pieces of wood and metal lying around.

Send a detailed description of your MakeShift solution with sketches and/or photos to makeshift@makezine.com by Aug. 17, 2007. If duplicate designs are submitted, the winner will be determined by the quality of the explanation and presentation. The most plausible and creative solutions will each win a MAKE sweatshirt.

MakeShift: Castaway

Make 367
Tomorrow is the last day to turn in solutions to the MakeShift challenge from volume 08!

The creator of MacGyver challenges you to survive on a deserted island.
There are few fears more primal than being cast away on a deserted island in the middle of who-knows-where. Maybe it's a throwback to our eviction from the Garden of Eden, or the nagging realization that Earth itself is just such an island in the endless ocean of space. Whatever the reason, it has been and remains a mainstay of the collective imagination.

The Scenario:
You are on a small sailboat in the South Pacific when a freak wave of Biblical proportions swallows your craft. You awake to find yourself on the rocky, sandy beach of--what else?--a tiny deserted tropical island. As the fierce equatorial sun beats down on you, you realize that the boat is gone, but a large section of the white, waterproof nylon sail has washed up on thet beach.

Relieved that you are alive and have sustained no major injuries, you quickly scout out the island. There is a cave for shelter, an abundance of vines and vegetation, but no trees to speak of. You see enough sea birds and marine life to provide a subsistence diet, but there is no source of fresh water! And the rainy season is still months away.

The Challenge:
Come up with a reliable way to produce potable water until you are rescued--or the meaning of life is revealed to you, and being rescued no longer matters.

Your items:
You have only the nylon sailcloth and what you were wearing when you washed ashore: a dark, waterproof windbreaker; a T-shirt; and shorts, in which you find your Swiss Army knife (or Leatherman tool) and a pack of waterproof matches. If it provides additional motivation, feel free to be cast away with the fantasy celebrity of your choice--but this person is still counting on you to provide drinkable water. And if you're looking for extra points here, forget the pack of matches.

Good luck, and rest assured that we're all out there looking for you.

MakeShift 05: Analysis, commentary, and winners

In 1960, Woody Norris read a contest announcement in a magazine that changed his life and set him on the path of being a world-class inventor. The announcement challenged readers to submit a plausible but fictional account of a supposed new invention to be published as an April Fool's joke. Woody took up the challenge. Here is the interesting part: during the process of trying to come up with a product that was both plausible but a bit "out there," he came up with what would ultimately be his first successful invention. The rest is history.

Coming full circle, Woody is now the one throwing down the gauntlet, challenging you to prove your makeshift mettle by staying alive for 48 hours in a bank vault with limited oxygen. Over 100 of you answered the call, and Woody and I had to break open the engineering and chemistry texts to evaluate a good number of the submissions. In the end, Woody selected two winners and two honorable mentions; to say that selecting two winners from the pool of entries was difficult would be to understate matters. It was flat-out hard.

It is interesting to note Woody's unique method of evaluation. Before he would evaluate any of the responses, he felt like he had to submit himself to the challenge and solve his own problem. He even set up an electrolysis apparatus in his lab so he could get empirical versus theoretical measures of power consumption and 0/H production. Then, he used his solution and data as reference points to evaluate the entries. Woody's Solution is included here for your review.

Thanks to the MAKE readers who took up Woody's challenge - check out all the winners here! - Link.

Can LEDs in refrigerators enhance the nutritional value of vegetables?

Creesto has a Make challenge - "OK guys, in my house we LOVE fresh fruit & vegetables, but cannot spend the time going to the store every other day to ensure that they are as fresh as possible. I remembered reading about a high-end fridge that had LEDs inside to keep the fruits and vegetables happier/healthier for almost twice as long as normal. I found this, the Mitsubishi Electric - Refrigerator - Folio Series:

"Increase Vitamins, Preserve Freshness In order to enhance vegetables nutritional value, Mitsubishi Electric has installed a photosynthesis LED in the crisper, creating the world's first refrigerator that utilizes photosynthesis to enhance the nutritional value of your vegetables. For the first time in the industry, we are introducing an amazing function that increase vitamins in vegetables. Vegetables are alive even after harvesting. LED lights is irradiated during preservation, and photosynthesis is encouraged, so nutritions such as vitamin C are increased and foods are preserved with vitamin C that are 1.5 times as good as before. Starting from the concept of controlling nutrition loss, we have been able to achieve increasing nutritional values in a totally new-concept refrigerator. Research showed that the light's color was important: The orange light creates chlorophll in vegetables without inducing them to grow. A small bank of LEDs in the roof of the vegetable drawer produces lights at a wavelength of 590 nanometers (orange). Mitsubishi Electric found that after three days, the vitamin C level in broccoli sprouts stored in their new refrigerator was 50% higher than in a conventional refrigerator."

Here's my question and subsequent challenge:

Can this possibly have value as claimed? I'm a bit dubious, as photosynthesis (as I understand it) cannot continue once the plant and fruit have been seperated (no leaves). But there may still be benefits, even if just to assist in efficacy.

So, if there is SOME benefit, this doesn't sound too difficult to make at home, as long as you know what you are doing: how to wire into an existing fridge, what LEDs to use, etc.

What do you think, is this a worthy challenge?

Makers, are Mitsubishi's claims possible? Post up if you think orange LEDs will actually make your veggies better, ideas on how to do this and test it.

Make a meat reddening carbon monoxide fridge?

Meat224
Trehugger has a Make challenge that I think we'll pass on...you see, the Food and Drug Administration in the USA allows supermarkets to pack red meat in carbon monoxide gas so it appears red for longer, and then more people will buy it - so...the huggers threw down the loin chop challenge - "Here is a project for Make- connect tailpipe to refrigerator and have better looking food.".

Making a $100 laptop for $75!

Remember the $100 laptop post/challenge we had on MAKE? We used an Apple eMate and hand crank (all less than $100) to see what was possible to put together with eBay, Freecycle and Craig's list. MAKE pal Mark Hoekstra of bicycle iPod charger fame picked up where we left off and built his own - here's how he did it - Link.

Hack this CMOS tiny camera module and win...

Sparkfun electronics has a pretty good Maker-style challenge - "This is a 640x480 pixel resolution CMOS camera used in the Samsung E700 cellular phone. While 0.3 mega pixels may not sound like a lot, this module is one of the smallest, lowest cost CMOS imaging modules currently available to the embedded market...We would like to announce a $200 prize to the first user capable of capturing an image on the new CMOS digital camera. This 640x480 camera is extremely small, low cost ($19.95), and based on proven cellular technology. Unfortunately we don't have much technical info to go with it. Up for a challenge?" Link.

DC Power Station for a lot of Cell Phones?

SpiderWrench has a Maker challenge! "Ok, I really need help with this. I have several prototypes without power, (or rather, I have been forced to use an AC power strip with 30 individual, ugly chargers and a mess of wire everywhere) here is the situation: I need to be able to charge 30 new cell phones on a single power supply. Through some risky experimenting on my part, I have been able to charge 3 cell phones off of a single wall transformer, and I know I need more power to get 30 up and charging. I have thought of using a modified laptop/PC power supply, and I think it will work, but I do not want to risk blowing up 30+ $300 cell phones which are not mine to blow up." Post up ideas in the forum! Link.

Ideas for crazy messy wire-wrangling

Great discussion in the MAKE forums! Leenwebb writes - "Like many of us, my house is filled with wires. And until we get the Broadcast Energy Transmitter from the GI Joe movie working, I need the wires. But here's the thing: they're ugly. And, often, in the way. So I am putting a call out to all Makers: What do you use for wire-wrangling?..." Link.
