Mechanical fire-breathing dragon automaton

Here's a great short film documenting the design and creation of a mechanical dragon. The hand-cranked automaton actually shoots fire!

Made by Rachel Grimmer, this was her first automaton project which she made for her medieval re-enactment group. The project included researching the history of mechanisms and automata, learning how to make an automaton, and then designing and making the dragon. In this short video, she describes the entire process.

When the crank is turned, the dragon flaps its wings, swings its tail, and blows a powder from its mouth. When blown over a nearby flame, the powder creates a dramatic fire effect. The piece incorporates a number of great mechanisms including a crank-shaft, pulleys, a skew cam, a bellows, ratchet, and a snail cam.

String-operated Japanese karakuri figure

Here is an interesting form of karakuri doll posted to YouTube by artist Osamu Kanda and attributed to GOTO. This figure differs from the spring-driven variety of karakuri in that it is powered by the viewer. A system of strings allows the user to manipulate the doll something like a stationary marionette.

Here is the web page with pictures and additional information (some English, mostly Japanese) about this string-operated karakuri figure.

Furniture maker Sam Maloof collected automata

Furniture maker Sam Maloof collected automata

Our good friend, automaton-maker and woodworking expert, Charles Mak, spotted something remarkable in the pages of Metropolis Magazine. The late Sam Maloof, renowned furniture maker, also had an appreciation for automata. The article focuses on Maloof and his homes, which one can tour. The picture shown here is part of a slide show associated with the article. There they are, right above the Native American kachina dolls: three wood automata. In another picture, one can see two whirligigs.

Here is the full article on Sam Maloof from Metropolis Magazine.

Action Toys: Plans for Toys with Mechanical Movements

Action Toys: Plans for Toys with Mechanical Movements

A reprint of a book first published in 1936, this work contains plans for constructing a variety of toys with mechanical movements. Only 36 pages long, one wonders how much detail is in this volume. Still, the description is undeniably intriguing!

From the book description:

This unusual early work presents a collection of toys with a variety of typical mechanical movements and worth-while construction problems. Instructions are extensively illustrated with diagrams. Contents Include: Tools and Supplies; Transferring Drawings; Sawing; Fastening Parts Together; Joints, Coloring and Finishing; Standing, Rocking, and Wheeling Animals; Jacks and Acrobats - Performers on Strings; Combat and Competition Toys; Walkers and Dancers on an Inclined Plane; and Carts and Chariots. Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Audio story about 400 year old monk automaton

Here is an audio program from NPR's fascinating program, Radiolab. This 20 minute episode tells the tale of a 400 year old monk automaton. The figure is made of wood and iron, stands 15 inches in high, and is powered by a wound spring. When activated, the monk walks, hits his chest with his right arm, moves the wooden cross in his left hand, nods his head, rolls his eyes, and moves his mouth as if in prayer.

The first remarkable thing about this monk automaton is that it is still in working order at the Smithsonian Institution. The second remarkable thing is the sequence of events that led to its creation. To learn more about this, you can listen to the audio clip embedded above, or follow the link below for a lengthy paper on the subject. Both are excellent.

Here is a link to an article on the automaton by Elizabeth King titled Clockwork Prayer: A Sixteenth-Century Mechanical Monk

Somewhat mysterious singing bird music box

mysterious singing bird music box

OK...so maybe not everyone has the $5.8 million dollars required to by something like the pair of singing bird pistols attributed to Frères Rochat. That doesn't mean you can't dream of a miniature mechanized singing bird of your own. Here's a beautiful example that can be yours for a fraction of the price. What that is...well...it's probably changed by now, so I'll let you see for yourself.

The ebay description is a little mysterious, but based on the current number of bids and the amount, I would say that there are people out there who know exactly what this is and that is worth something.

Quality automaton Music Box possibly from France or Germany. Gilded finish bronze box, bombe sides, fleur de lis decoration. A slide switch releases an hinged oval panel on the top. Bird stands for the duration of the tune. Found in the original cloth lined storage box along with the key (for winding) that is fitted in the hinged cover. Black exterior. Unsigned.
Music Box is 4"W x 1-1/4"H x 2-1/2"D.

Here's the full listing with many nice photographs of this somewhat mysterious singing bird box.

$6 million dollar singing bird pistol automata

This pair of singing bird automaton pistols made the rounds all over the internet a few weeks ago. I didn't post about them at the time because they seem to be so well covered. Even so, I would be remiss in my duties if I never shared them here on The Automata / Automaton Blog. Perhaps a few of you missed these astounding works of mechanical art? Prepare to be dazzled.

Created by Frères Rochat of Geneva, Switzerland around 1820, this is the only known pair of of singing bird pistol of their kind. The matched set is made of materials that include precious metals, diamonds and pearls. After winding and pulling the trigger, a tiny bird -- complete with real feathers -- pops out of the barrel, flaps its wings and tail, spins about, and opens its beak while singing a realistic birdsong. All of this in an incredibly small scale. What's more, the set is in unbelievably good condition. Do watch the video included here. Amazing.

So what is a rare treasure like this worth? Christie's auctioned the set off last month for $5.8 million USD in what was described as an epic bidding war between two prominent collectors.

Here is a link on the Christie's web site about the Singing Bird Pistols by Frères Rochat

Help make two giant serpent sculptures a reality

Here is an awesome project by Jon Sarriugarte and Kyrsten Mate. These are the folks who created the awesome Golden Mean snail car. Back in 2009, I had the pleasure of sitting in the snail car and shooting fire from the antennae. It's an experience I will not soon forget. Their latest project involves a pair of giant serpents! Though the project is initially for Burning Man, like the Golden Mean snail, the serpents will live on past that event and continue to delight and amaze people for years to come.

They are in need of some funding to make these kinetic sculptures a reality. They are well on their way, and have started a Kickstarter page so that people who love wild kinetic art can support their efforts. Please consider donating.

How to fix a cam, gear or handle to a wood shaft

Cams, gears & handles attached to wood shafts

My latest installment of Dug's Automata Tips, Techniques and Tricks is now available at on the Cabaret Mechanical Theatre web site.

There seems to be fairly widespread agreement that there are a handful of particularly useful techniques for attaching cams and other parts to round wooden shafts. There doesn't seem to be much advice on why you might choose one method over another. I've tried to address this topic in my latest column. I've given an overview of the methods and some of the factors that make one technique more suitable than another in certain situations. I've tried to provide a few helpful tips along the way.

Here is where you can read the full article Attaching Cams, Pulleys, Cranks, Gears, and Handles to Wooden Shafts by Dug North.

Book about Ancient Greek Gadgets and Machines

Cover photograph of the book Ancient Greek Gadgets and Machines

This 152 page book, printed in 1966 (paperback) and again in 1975 (hardcover), covers the inventions attributed to the ancient Greeks. It includes both drawings and photographs of the subject. Of particular interest is the section dedicated to the design for the first steam engine created by Heron of Alexandria.

From one Amazon Reviewer:

Basically, the book keeps what the title promises: it is a brilliant account of ancient Greek gadgets and machines, focusing both on the explanation of the most important inventions and on the famous inventors they are attributed to. Further, Robert S. Brumbaugh gives concise and enlightening descriptions of different Greek philosophers' attitudes towards machines. This, combined with Brumbaugh's absorbing writing style, makes Ancient Greek Gadgets and Machines a most rewarding read.

The author, Robert Sherrick Brumbaugh, wrote extensively on the subject of ancient Greece.

Here is where you can pick among used editions of the book Ancient Greek Gadgets and Machines.

Meccano Birds wind-up automaton by Aaron Ristau

This elegant little kinetic sculpture by Aaron Ristau depicts birds in flight. The birds are powered by a small wind-up motor that will run for about a minute.

Much of the mechanics of this piece are made from Meccano -- a model construction system consisting of metal plates, wheels, axles and gears, with nuts and bolts to connect the pieces. Americans will know the modern version of this system as Erector sets

Shoes were made for walking - automaton

A pair of children's shoe lasts, an old pipe rack/humidor, and a lot of ingenuity come together to make for a wonderfully dynamic hand-cranked kinetic sculpture. This piece is by artist Aaron Kramer. I love how the feet not only walk, but the piece itself is trying to walk off the workbench!

Mechanical Living Picture Of The Great Houdini

I posted the other day about a hand-cranked wheel cutting engine made by Kevin Wright. If that piece demonstrated his technical side, this one demonstrates his creative side. This mechanical picture depicts the magician Houdini in the classic manner --- that is, with a devilish imp whispering the arcane secrets of magic into his ear. All the great magicians (nearly) had their portraits done in this manner. This one is uniquely expressive. Houdin's eyes and head move, making it appear as if he is considering what his is hearing and perhaps making sure that nobody else overhears.

Scratch-built hand-cranked gear cutting machine

Scratch-built hand-cranked gear cutting machine

This is a working wheel cutting engine based on historical designs. "Wheel" is the term that clock-makers use for larger gears, while "pinion" is the term used for smaller ones. This gorgeous machine was built by the talented Kevin Wright. Wright designed the engine to cut the gears for a mechanism he wanted to build. Basically, he built a machine to build another machine!

A metal blank, brass in this case, is mounted to the top of the spindle in the center of the engine. The large circular disc below is an indexing plate. A spring-actuated lever drops into notches in the wheel allowing wheels with different numbers of teeth to be cut. The cutter is mounted to a hinged assembly above the blank. When you turn the crank, the cutter spins. The spinning cutter is then lowered into the blank to cut a notch in the gear's edge. The index wheel is used to rotate the blank a specified amount, then the process is repeated. By this method, a complete gear may be cut.

Scratch-built hand-cranked gear cutting machine

While Wright has modern tools to cut gears and pinions, he wanted to experience what the clock-makers of old went through. They built wonderful precision mechanisms with tools very similar to the one he made. He says it is very satisfying cut gears without the use of electricity. I imagine so!

Art & technique of Scandinavian style woodcarving

Art & Technique of Scandinavian Style Woodcarving

Here's a book by the talented woodcarver, Harley Refsal. He is a master of that lovely Scandinavian style of figure carving that uses a single carving knife and leaves distinctive large flat facets on the carvings. I have DVD in which he is featured and can attest to his skill as a carver.

From the book description:

Directions, front and sideview patterns, and step-by-step photographs reveal how to make a few simple cuts and leave large flat planes intact. The lively personalities of such typical Scandinavian figures as Oskar and a traditional Swedish folk art horse are charmingly rendered in the samples and projects included.

Keeping the tradition of Japanese Karakuri alive

Here is a wonderful short film about Hideki Higashino -- one of a few artisans still working on Japanese Karakuri. He learned the tradition from his father. The film was shot by Matthew Allard.

From the video description:

Japan has always been on the forefront of cutting edge robotics. Its roots can be traced back 200-300 years during the Edo period when skilled craftsmen created automata (self-operating machines). Using nothing more than pulleys and weights they were able to make the Karakuri (Japanese automata) perform amazing tasks. Japan's modern day robots can be traced back to the Karakuri. Today, Hideki Higashino is one of the few remaining craftsmen who is determined to keep the history and tradition of Japanese Karakuri alive.

Here is a link to more Karakuri posts here on The Automata / Automaton Blog.

The LEGO Technic Idea Book: Simple Machines

The LEGO Technic Idea Book: Simple Machines

Back in March, I mentioned a series of books about LEGO machines. I took a closer look at one of them, The LEGO Technic Idea Book: Simple Machines. This the first in a three-book series on using the LEGO Technic building sets to learn about and create mechanisms and machines.

Among the topics covered in detail are:
  • Gears
  • Shafts and connectors
  • Gear combinations
  • Gears in a turntable
  • gears in series
  • Angled gears
  • Worm drives
  • Chains and treads
  • Rack-and-pinion gears
  • Motors and gears
  • Reciprocating motion
  • Changing the direction of motion
  • Chains, belts, and shafts
  • Building techniques
  • Pulley systems

There are hundreds of projects, each carefully photographed from several angles. The projects are meant to give the reader an understanding of mechanisms and to encourage you to experiment on your own. It's a great concept, well-executed. Here's one simple machine you'll get to tinker with:

The one challenge that seems to accompany this and the two companion books is that the author, Yoshihito Isogawa, must have access to a great supply of specialized LEGO parts. To makes things a bit easier, he has published an illustrated list of parts that are used in the books. He has also offered his expert opinion on which LEGO Technic building sets come with the best parts for exploring mechanisms. Here are his top picks:

Great veiws of a classic Paul Spooner automaton

Some great footage of Paul Spooner's classic automaton titled How To Live No. 17 Spaghetti

From the YouTube video description:

The action on the piece is superb, and features a man practising the art of spaghetti eating, (which can be messy as a trainee) in his bath. He leans forward, and takes a bite of the never-ending pasta, chews and then starts again. To add flavour the taps are endlessly producing swirling tomato sauce and Parmesan cheese.

Here is where you can learn more about this and other limited edition automata available from Cabaret Mechanical Theatre.

Monster Head Study No. 2 - beady-eyes & fangs

Back in April, I told you a bit about a creative block that I experienced during the winter months and how making little wooden monster heads saved me. My idea was to get into the workshop, use my tools, maintain my tools as needed, and produce something in during each short session. I promised to show you more of these studies. This post is about the second monster head I made.

I would often start with a small hardwood sphere, commonly found at craft stores. These 1 inch unfinished wood balls come in packages of 12 and are a light, clear-grained wood -- probably birch. These seemed like a good place to start since they are already somewhat head-shaped. What I didn't fully realize is how hard these balls are! Power carving with a Dremel tool worked fairly well, though I had to be careful about burning the wood. Working with a carving knife proved to be very difficult -- not only because the wood was far harder that the basswood (lime) I usually carve, but also because they were difficult to hold. The latter problem was solved by drilling a 1/4 inch hole in the ball and inserting a length of dowel. This provided a handle so I could hold the piece while working on it.

Monster Head Study No. 2Dug North's Monster Head Study No. 2

Once I had nearly finished this guy, I thought it had a somewhat bat-like appearance. So, I found some round red glass beads I had, drilled eye sockets, and glued the beads in place. The pupils are actually the holes used to string the beads. I did a little bit of wood-burning to create those angry eyebrows. Like Monster No. 1, this one has that under-bite of which I am so fond. The two small upturned canines are made of tagua nut -- a hard white material often used as a convincing ivory substitute. The ears (horns?) are made from some scraps of Baltic birch plywood I had sitting in the scrap pile.

As with the first, this monster has no name other than "Monster Head Study No. 2". Taking photos of these monsters is not easy! The wood is so light, they tend to wash out under the lens. They probably need some type of finish to tone them down and give them some depth. I may also need to spend some time learning how to photograph such things.

I liked this one when I made it, but having made many more monster heads since that time, this one has slipped down the list. Still, it served a valuable purpose: I was creating, exploring, and -- most importantly -- getting out of that rut. Hopefully, there are a few useful ideas, tools, techniques, and materials mentioned in this post. There are more monsters to come, so stay tuned.

Magician levitating a woman by Decamps c. 1920

Here is one of several pieces going to auction this Saturday, June 4th, 2011. This piece depicting a magician levitating a woman was manufactured by Decamps around 1920. The figure has painted composition hands and head and multiple movements. To get a sense of scale, the magician figure stands 28 1/2" tall, so it is fairly large. It's estimated worth is between $4,000 - $6,000 USD.

The auction is being held at:
San Rafael Auction Gallery
634 Fifth Avenue, San Rafael
San Rafael, CA 94901

Here is where you can get more details on this and several other French automata going to auction.

French-made magican automaton from the 1880s

Here's an antique automaton depicting a magician performing a cups routine. As music plays in the background the figure raises and lowers the metal cups. The objects under disappear and transform into other objects.

Made in Paris around 1880, the figure is made of papier-mâché with clockwork mechanism and music box inside the base. Most remarkably, this gentleman is wearing his original clothes! While the secret of the magician's trick may not be all that secret, it is unquestionably a fine piece with a rich history.

Contact The House of Automata for more details on this automaton.
