Shopping list

1 leg
-about 15 m of PVC PIPE.
ROUNDWOOD fitting in pvc pipe (40 cm)
-rope.
-glue (wood-plastic)


(10 pivots)
-40 screws
-40 cm round wood.
-40 Screw in-hooks
-10 Long bolt fitting the hooks, 50 nuts to close



I'll start with one leg and a frame, if that works, I'll make the other 5


To make the frame:
2 boards of +/- 205x50


Some beams spanning 40 cm (x8?) more screws..





The gears and axes:


Something that can to this and is about 50 cm long


Rather thick (5/10 cm) wooden plates to make the gears, I'll have to work out the respective sizes.

wintery intermezzo


We had a lot of snow (by Dutch standards) this past two weeks. I had shoveled all the snow in the backyard into one big heap and it kind of looked like a dragon.
So when I had the time, I took one of the kitchen knives and started carving.
I was very happy with the result. (Painted it's Eye light blue). Now after two days of thawing it has been reduced to a shapeless lump. Alas my dragons are not built to last.
It did give me a clear idea of how big Yoris will be, as Yoris would be about twice the size of this rather large dragon. My son Tim (5) without any knowledge of English gave the best possible description of this dragon: "Cool!"

construction draft.


This would be the construction, but I'll have to think of something for the neck gear..
Else the beams connecting to it, will have to go through the axis..

Lengths of the legs and positions on the frame..

This might be a bit technical, and boring, but I need these values to be preserved and this is the easiest way. With these lengths the animaris draconis will be two meters high at it's highest point in the cycle:

Thinking further on the gears

I revisited the mechanism and started calculating..
Also I left out four smaller gears for two larger ones, this will decrease the amount of drag from the gears.
Since three red gears have to move as one and there positioning is crucial, I had to calculate the sizes and positions of the connecting gears exactly. Also I found it esthetically pleasing to have the neck-bob at about half the standard gear speed.
The ratios had to be determined, so that the number of 'teeth' on each gear would be an integer, else the gears cannot connect.
After two hours or so I came up with 4 standard gears of 40 teeth all having the same speed (the red ones and the yellow one). 
A gear (purple) scaled 240% giving 96 teeth, with a speed of 41.667% of the standard for the neck.
A gear (cyan) scaled 325% giving 130 teeth (and a speed of about 30%), connecting the standard gear with the neck gear.
A gear (fuchsia) scaled 275% with 110 teeth (and a speed of 36.4%) connecting the two aft standard gears.

This is math at it's finest. You can actually create something in advance, and know it will work perfectly. Just to be sure, I simulated the gears in flash and found something out.
I'll have to revise my scetch of the body shape (background, grey) a little bit, because some of the gears were sticking out.


in this detail of the standard gear stuck between the two oversized ones, you can see how needly everything fitted and why I felt like da Vinci for working it out in advance.. (Or maybe Hannibal from the A-team, saying: "I love it when a plan comes together!")

The mechanism



A move with character

Friday, November 6, 2009

The movement complete


I completed the movement of Yoris (yes I changed the name) and am very happy with it.
Also I sketched a skin and muscle tone and decided on a scale. It turns out, that the head should be about twice as big as I made it now..

the horns and teeth



The latex paint was a spectaculair failure, it doesn't smooth out the structure, it seems to amplify it. But I finally produced a result for teeth and horns that I like.
I used a base of PUR, in which I cut out a shape with an ordinary kitchen-knife. Then I used red paint and a layer of yellow, black and (white) smooth-area filler. This gave a dark gray brownish surface, but with organic color-nuances.
After this dried, I could sand it and it covered almost all cracks.
Then, I put another layer of filler on, applied some yellow and white paint to the still wet surface. This I smoothed out with my fingers. After this dried, I put on some email-off-white (not quite ivory, but egg-white) paint. I took it off again with some toilet paper. Then I fingerpainted with yellow and black on the tip, because I remembered cows-horns are darker at the tip. I also took that of with toilet paper.
All in all, its smooth and has a defenite hard, rock like look. When I varnish and polish it, I excpect it will look like a horn.

The beauty of this process is: it fits right in where it should on the dragon's head. (on which, as you can see, I have been experimenting with the texture.I took most of it from the sketch I made earlier.

The model leaves spots for four horns on the dragon. (originally it was six, but I cut down on horns in favour of an ear)..
So all I have to do is make 5 more. But I'll wait with that until I have the final model, which I probably cannot make, until I know the exact scale.
To get the scale I really need to start work on the legs again. But this was just so much fun. And the legs are technicall..

making the head look better

I was very pleased with the PURRED result. It is light and sturdy.
The paper triangles filled out, so they bulge out. Normally a paper model would start bulging in because you apply pressure from the inside. This causes lighting to accentuate your triangles.
One seem did split a bit, so if I had a fully textured head, I'd have to touch up a few parts, but no problem.
So PUR seemsto work great as long as you give the stuff an escape -route (in this case the eye and nose) when it is expanding.

But now I couldn't resist making teeth out of leftover bits of Pur, by carving them with a knive and painting them. When you carve PUR, you get a surface with many holes, so the teeth aren't that good.
Also you cannot paint this PUR with regular paint, I guess latex will do it, but I haven't got any right now.
This was a bit disappointing.

So I started work on the lower jaw, wich I textured in Lightwave. Not an easy thing to do and I still don't feel I have all the control I want. The texured sheets, I got out of Pepakura, I printed and laminated with BOEKLON, it is basically a plastic sheet you stick onto the paper you want to preserve. It's relatively expensive, but it is completely waterproof. I even tried to carve the scales into the lower jaw, by tracing the lines with a pair of scissors. This way, the light seems to hit the scales. Also I like the way, the thing shines..

This was great, but I feel like when you have lots of scales, which I'm planning to create, this will be too much work, even for a perfectionist, such as myself. The effect is too subtle.
Also I didn't quite like this texture, which as you can see has been stretched because of my lack of knowledge of texturing in lightwave. This seems to accentuate the triangles again. I found I needed more contrast, more dark and a denser pattern in the texture. Also the tromp l'oeil of the lighting of the scales (you now see it upside down) can be stronger. And finally I don't like the texture. The bits don't overlap and its too much of a fish or crocodile skin now.


I did like this however: I prepped the seams with glue, so that it would be watertight and after the glue dried, I put it under a running tap. No amount of rain can match this abuse, but the water-proofing held. As you can see, a small amount of water got through on two seems, that I didn't get, but it hardly interupts the texture.
Also there is almost no discoloring. So it seems, we can build a water-proof or at least rain-proof dragon. That is a load of my mind.





 I also tried different methods. The head, I painted black (just the nose, to give it a try) and I created scales by fingerpainting. You put a litte bit of blue on the tip of your finger and put white and darkblue at the edges. Than you put a fingerprint/stamp on the dragon. It's really easy to do and would be great if I wanted a simple look. The textured version is much more sophisticated and can be much subtler in colour. Also you can see the problem with the teeth, which are made of carved PUR. So although this was fun to do, I decided against it for now. I did learn however, that by making the dragon's skin dark, the triangles dissapeared altogether. I just need to put black on the overlap of the bits I glue together, or I'll have little white stripes everywhere.
Also I learned that a great way to get some defenition out of pepakura even with low grade textures, is to print a textured version of the model to PDF and then open it at high resolution in photoshop. There you can fix the resolution, by repainting and touching up the texture. After that you can print it from photoshop.



I also experimented with a little thing called Enzo . It's a plug-in for photoshop that allows you to open 3D objects (lightwave and many others) and paint directly onto the 3D surface, using everything photoshop has to offer.
You can then go to a flat view, where you have a layer with the UV's.
Here you can paint your texture and apply it back to 3D, touch it up and so on. It is a great tool, although 299,- is to much for me.
After all, you can do about the same thing in lightwave and almost every 3D package. It just takes three times longer, because you have to switch programs every few minutes.
I started experimenting with this, because I have a colleague, who feels right at home in photoshop, but is not that happy in any 3D program.. This might be a good solution for that problem. But it's not worth 299,- in my opinion. I did use it to create the texture that I like the most, up to now.

papercraft weekend


I finally got round to a full papercraft upperjaw. (I colored it artificially just for fun, it's white.)
The horns are missing from the cheeks, but it gives an idea of the size of the head (57 cm)
Iand the material needed. I used 10 sheets of A4 paper to fold it. All in all it's not that much.
Can't wait how it turns out, because this morning I flipped it over and poured PUR foam in there.
It will probably bulge out of the eyes and nose, but I'll just cut the holes back in then..
Also probably the best way to make those big horns on the back I could do by pouring a little PUR in, let it harden, get the next stage, pour PUR in etc. Although I'm not a very patient guy.
If it turns out nice, I'll make the cheek-horns, ear flap and lowerjaw for a good idea.
Some details on the model need a little work and then it's texturing time.
But before that, I'll concentrate on the legs. I think it is very inspiring to have a complete head lying around, though. Also I saw a change in how people now talk about my plans.

The eye

Today we'll be making a dragon's eye. Ingredients: plastic sheets, margerine or butter, permanent markers, hobby glue, candles and matches, some yellow chalk..

I started by building half a globe out of a plastic sheet, using a dot, which radiates sphere parts.
I folded it to what -according to my children- resembles a custard cup.


I put a lot of margerine in the custard cup, to smooth out any folds and creases with my fingers. Also it'll make it easy to get the glue off, once it hardens.
On the layer of margerine, I poured glue and let it harden for a while. Then I made an Iris and a pupil on the same transparant plastic and dropped it in. (NOTE: next time, I'll not use a loose pupil, because it shifts when the glue hardens) On top of tap I sprinkled some yellowish crayon to give the eye some texture both unlit and lit. Then on top of that, a layer of wax from a couple of small candles (waxines).
I topped the wax with anoher layer of glue, because it crumbles at the edges and I wanted the glue to keep it together.

This is the result, after hardening a day (I'm not very patient). The glue was still a bit runny and my pupil shifted a lot before it could set. But I could already test it's translucency with a (weak) flashlight behind it.
The glue forms bubbles, as it sets, but I don't think it's bad. It just gives a little texture to the eye, so I don't really mind. It looks like the dragon has been in a few fights. The wax and glue are translucent and the wax and crayon-dust produce a very warm glow. Next time I'll make my iris a litte darker, because it hardly shows here. Finally, this globe-shape is only to allow the eye to rotate. In the model I want it to look something like this:


There you have it, a dragon's eye in a weekend. Oh, yeah, for credits, I ripped the skin for this last picture from flicker and changed it's color. Just type in dragon eye in google and it's the first one. I'll probably shape it a little differently, but I like the horned eyelids. Also the amber glow and the blue go well together.

back to work

Ok, so enough with Barcelona, back to work.
I was trying to create a model, I made with peppakura. I turned it inside out, so I have been stupid.

Now that I get pepakura better, I tried again, while texturing the model with a dragon skin. I like the result a lot.

It weighs only 2 grams for a length of about 20 cm.
But it is flimsy and will not keep it's shape. Also it will dent or rip at the slightest pressure.
So I build this model a few times and started to experiment with ways to reinforce it.
My plan is to first stick plastic onto the printed sheets, to make them water-proof.

I tried glue on the inside. This works. It grows a lot heavier, but it will no longer rip and became quite rigid. Although it will still flex a little. Excellent for the paws. It takes a lot of glue, and a lot of time to dry. The weight increase to 8 grams.

Next I tried PUR (polyurethane foam), the cheap kind. Bert warned me about this, so I came prepared.
I applied generously, once and the way it says on the package. (1/3 full)

The first went over the edge, pushing the paper out of shape, while it expanded. The second (the one that was 1/3 full) never made it to the edge, leaving holes I couldn't fill anymore.

Finally I took one, which I had filled to the brim, while it hardened and cut the extra foam of with a knive.
Then I peeled of the paper, because I thought I could shape it more organically with a knife. Now if you ever did this, you know the inner texture of PUR is that of swiss cheese. So I forgot that and went back to the paper+ PUR.

This proved VERY strong. I can even stand on it, without it breaking. Yet it weighs only 12 grams. It has the benefit of being textured. It has the disadvantage of blowing up the paper shape.
It does make it less geometric and more organic in the process. So I don't know if that is such a drawback.
Also I used 120 grams paper, I could go up to 200 grams.
I guess I can make the body, the head, neck and tail out of these

Also shaping PUR with the knive I finally know how to make the teeth (you don't want to fold in that kind of detail) or the horns (they should be subtly curved to get the right look). You can just cut them from a block of PUR (If you leave a hand-sized blob to harden for more than a day, it is dry on the inside as well.
This way I made the fake sharktooth, you see in the picture and at the back I made a Yoshi Egg just for fun.
It's strange material to work with, but it's something I can get used to.

So now I know how to make:
  • The firebreathing (fireball shooter still in working order after many fireballs, I demonstrate it to people, because I'm a pyromaniac and because they seem to like it.)
  • The smoke (our brilliant smoke machine (also I hear about a smoke-cookie))
  • The 'flesh' and skin (paper shells and PUR, glued together
  • bits of skin that need to be able to flex (paper, plastic and glue)
  • Teeth and horns (PUR, cut)
  • The kinematic-bones (wood and joints, rope and some PVC pipes)
All I have to figure out now, is how to make the eyes (I'm thinking of an electro motor in the head turning two amber marbles and at the same time opening the mouth) and the transmission (I want to break the body up in three parts, so it can take corners, but the wheels still have to be connected, I thought something up, but I'm not sure it will work in practice)

So progress at last...

dragon's everywhere

So, after a long dry spell, I have some free time (and energy) to blog again.
Barcelona proved great I was inspired by Casa Batllo (batljo) by Gaudi, also Barcelona is the city of dragons and the fantastic. I never saw so many dragons, maybe this is because of Gaudi's dragon at park Güell. I took the usual picture, but I hated it.. It's not a dragon at all. It's more like a squatting frog.
Casa batllo, however was great. It turns out to have a great big dinosaur inspired structure on the roof. The colors of casa batllo were very inspiring as was the tiling..

After this it was dragons everywhere from a statue of St Joris made out of chocolate!!! (We saw this in the museum of chocolate)

To the gargoyles on the main fountain in Park de la Ciutadella (small city)

I saw a beautifull plastic dragon in a toyshop (Imaginarium) and bought it, but I left it under my bed in the hotel.

Also we saw a dragon reputedly also by Gaudi, but a lot more like a dragon, than the one in parc Güell. We hopped of the hop-on-hop-off bus (Don't ever take this, it's hot, you don't see anything and it cost 21,- euro's a person, while the metro will get you anywhere for 1,25)
We jumped off, because we saw something like parc Guell en figured we ought to be in the neighbourhood. It was made out of bolts and screws and stuff and looked ok.
Walking back to the bus I saw another one on a gate.


The finally going back to the airport (over de C-31, avinguda de la gran via) we passed a huge dragon,climbing a billboard.
 
Now I did NOT look for dragons, this just happened. I guess it's like seeing pregnant women. (You don't unless you know someone close, who is pregnant)
Ok, so finally, the obligated picture. Just for fun I took the exact picture every Japanese tourist who ever went to Barcelona has.. (Not true of course, I talked to at least one, at the magic fountain, who I bet would bite of her own fingers rather than raise them in this misunderstood victory-sign. Thanks to her I now know it's kilei na mizu instead of kilei no mizu..)

Obligatory Gaudi dragon picture with Japanese handsign for zashin-no-heiwa.

Pepakura

I spoke to Bert Simons today, who pointed me to Pepakura. These guys seem to have a free download of the program I was going to make. They even have a little dragon as a logo.
It has it's drawbacks with large files, but for now, it will be fine for my first tries. As Bert told me, start building and then learn how to do it.
Also he didn't use purely Blender, so I'll have to figure it out myself as well. I like to mix in every program I can get my hands on aswell :)
We talked about different techniques and materials. I had an idea of using Pur-foam, as it is inexpensive. This will probably not work. Also I'm considering now that I might need more than just paper.
Cardboard might do it, otherwise I can make some kind of ribs..
I like the idea that you can print on paper and that it's light and cheap, but I does dent when touched.
I'll know more, when I make my first model. But first it's off to Barcelona tomorrow to gaze at Gaudi's work.
I even found a Gaudi Dragon on Google Earth.

no time to blog

Oh, no! The beginning of the end..
No worries. I got my robotic horse in the mail this week, so I'm building..
No time to blog..
Also I'm perfecting the animaris draconis' legs. I'm not happy with the hind leg yet, so I won't show you now. SOon.
I'll be going to Barcelona on thursday and next weekend is my wifes' birthday.
So I don't know when soon is..
I'll be speaking to Bert Simons, who is the guy who did those great papercrafts on wednesday evening. Then I'll know more about how heavy, how sturdy and other stuff that might be usefull in the design process.
Also my unfolder is coming along nicely in Flash, I'll be publishing it as a webtool when finised as it is simple to use and gives a lot of control..

Why do I do this?

It just seems you have to have a goal, to have a wonderfull journey..
Allready I found such awesome stuff, that I wouldn't have found out about, if I wasn't heading somewhere.
If this all doesn't work out and I never build a dragon, then I've had these cool things already:
  • I've seen dinosaurs come to life..
  • I've recreated the steps Theo Jansen took to evolve his Animaris Vulgaris and created my own variant of the species.
  • I will own a robotic horse soon..
  • I've been to a REAL magic shop.
  • I've built and operated a fireball shooter (which is a big deal for a ex-pyromaniac)
  • I've found a way to make 3D-models real by folding them in paper.
When I set myself a problem, I start thinking in creative solutions and it's wonderfull to see others having the same mindset. Also it helps to look for it. I was determined to learn exciting things in this project and it's happening.

I'm reminded of a trip to Japan, where I took a gift for every day. Everyday I was determined to give a gift to the person/persons who would help us the most. I've never seen so many helpfull people in such a short time. This may be due to the structure of japanese society and the fact that they are very willing to make your problem their problem. But I will never forget the incredible coincidence, that lead me to speak at length with one of the great Zen-masters of this time Soen Ozeki. I would have never met him, if I wasn't determined to have the best journey ever.
I feel similar things are about to happen.

Now I hope I will reming myself to read this when the moment of despair comes, that must come on any great journey.

More than one way to skin a dragon?

I made a program in flash, which can turn a 3D-program into a papercraft (bouwplaat)..
It's still a bit crude, but I see great potential, as you can actually print scales on the dragon this way.
While looking for the english term for 'bouwplaat' I stumbled upon this site and WOW:
http://www.bertsimons.nl/zenphoto/paperworks/harry/
This really seems to be what I want and it's a Dutch guy doing it. So, I'll email him and see if I can learn anything. He seems to have the same idea but uses textured models scanned from real life as a startingpoint. Also I saw some retextured humans..
I want to start from a model, which only exists in the computer, but the idea is the same.
His results are in one word spectaculair.
The artifacts (folds) that you get from making polygons out of paper are just like I imagined: They look like scales, perfect for dragons!

Modeltime

My father came by and brought the raw material for a knee joint. I had made a cardboard model. We talked about the models and the difference between the animaris leg and the draconis leg..
The animaris vulgaris is what Theo Janssen calls his "strandbeest" in latin. He uses a leg, which can be built in one plane (none of his connections intersect). My version of the leg, however, needs two connected planes to operate, because parts intersect. Now I think my leg is more aesthetic, but I cannot deny, after making the first model, that it is less solid and wobbles a lot.

So we talked about it and experimented a bit with the animaris' legs ratios. If we could make it more slender, it would be better for our dragon. We discovered we could do it, without changing the ideal foot-curve by much.
So now I'm torn. I would like to make something original and not copy TJ's work or even make a version of it. But I'm starting to understand how brilliant his invention is. To have the whole machine operate in one plane, makes it sturdy and easier to build.
I want it to work more, that I want to be original.. I think the whole thing is original enough if I get it to work, but is this the moment to start making concessions... hmmm.

Also to prevent wobblyness we decided to go for narrow beams of wood for now in stead of pvc pipes.
I bought some sewing-machine-box-hinges (triple word value!!)  and other stuff to make a very small model in wood. If that works, it would prove my concept, but maybe I shouldn't try it at all and first re-work the model..

I've decided to sleep on it.

I demonstrated the fireball-thrower.. It's a cool effect and works every time now, we defenitely want it in there.

Sponsor (2)

I just heard, that we do have a sponsor. Ludatic is going to sponsor Joris the Dragon.
So now I have a modest budget..
The latest calculations showed a knee joint to cost about 9 euros at 6 legs at 6 joints each and another 6 in the nek, the joints alone will cost 360,- euro.. That's leaving out the body, the skin, paint and the smokemachine and fireballs, but I hope they will set us back about the same amount.

model of the head

I find that now that I'm building the dragon in 3D, I go back to the classic Dragon look. So the mammal like quality of the drawn sketch has disappeared somewhat. This is a classic European dragon and I think it's kind of fitting, because of the name. The only thing I left out in this 3D sketch is his ears, by the way. Ears are always hard to create in 3D.
Here is the simplified model so I can fold a hollow version in paper or make it from straws. It has no horns yet as I don't know if they will be part of the whole model yet.

New experiments with fireballs.

I MUST HAVE A FIREBALL! I couldn't resist trying a new approach. A slightly wider tube (this time I made it out of cardboard, which seems silly, but works fine).
Also I made new ammo. A VERY small piece of flashcotton, wrapped in a little piece of flashpaper (like a thimble) with a little piece of unattached flashpaper wrapped up in a ball..
So here are a few of my fireballs, the biggest one flew about 1,5 meters. The smallest never left the shooter. The beauty is that if you mount a single fireballshooter in the dragons mouth and prepare the pellets, you could fire it multiple times. I could even pretend to feed the dragon while replacing the pellet. The ignition I would like to feed through the chain, with which I want to pull the dragon. But it needs to be perfectly safe, because there'll be a lot of folks wearing inflammable outfits..

The Name (Yoris)

My collegue came up with a great name: Yoris.
It sounds familiar doesn't it.. The English equivalent is George. So it's Yoris the dragon..

Wanna know Why:

Yoris is the anglicized version of the Dutch name for St George (Joris), who reputedly defeated a dragon
Joris was a pet rabbit of my wife.

---NERD ALERT----
If you are not an extreme sci-fi or fantasy fan, don't read on and stick with the explanation just given. If for whatever reason you want more of the truth, read on..
---NERD ALERT----

The best science fiction and fantasy names in my opinion are Dutch words pronounced in English or otherwise anglicized.
The proof:
  1. Darth VADER. "I am your father" translates to dutch as: "Ik ben je vader.."
  2. Firefoot (one of the horses of Rohan, lord of the rings) is actually Viervoet(er) which means quadruped.
  3. Balin (the hobbit), is "balen" anglified, which means "to be really bummed out".
  4. Kalin Trose ("Star Trek: The Next Generation) "Kalen"= "the process of going bald".
  5. Rok, the giant bird, means skirt in Dutch..
  6. Kili, a name from Silver Surfer and also from the Hobbit, is what Dutch people will say repeatedly to a child when tickling it.
  7.  Zeist is the planet the immortals came from in Highlander II, this surpised me, because it is a town near Utrecht. (I always thought those people were kind of funny looking)
I have many more examples, but I'll risk looking even nerdier than I am..
Now to drive the point home:

Dutch just seems a science fiction natural.
It is just strange enough to be interesting and it's just a bit familiar as Dutch has ties with many european languages. Dutch also is a relatively unknown language as only 22 million people speak it and they all live close together. Also Dutch people make a point of learning YOUR language.
I suspect this is something we picked up in the past, doing business in foreign countries. It is very handy to have a secret language during negotiations to be able to talk to your colleagues about what you think this yoyo is willing to pay.. And you can say, you are being polite at the same time, because you learned their language..
But Dutch local history gives us away. To hide converstations with colleagues in negotiations the fishers-language Krang was invented in The Netherlands itself.
Krang consists of the sounds of Dutch words reversed. So the sentence "Waar is mijn bril" becomes "Raaw si nijm lirb", which is unintelligible to a non-krang speaker, but easy to learn or reproduce, once you know the secret.
The english equivalent would read: "Where are my glasses?" becomes "Rehw rah I'm sessalg?")
My wifes grandmother was one of the last living Krang speakers, which is where I learned about the art.. She could instantly translate large sentences containing modern words like 'computer' without losing a beat.

So to conclude my advice to all wannabee science fiction writers (or dragon builders) is: BUY A DUTCH DICTIONARY (or wardenbook)

Fire and Smoke

I was wondering if we could make smoke come out of the dragons mouth and maybe even think of a way to make it breath fire (in a safe way!)
I started out thinking about smoke machines, but they are all huge (5 Kg and more).
Then I looked at this thing. It uses 40 leds to get a realistic fire effect is only 16 x 16 x 12cm for a flame of 22 cm and it weighs 1,1 Kg..
This is still a bit heavy and it runs on AC, so it isn't perfect, but this seemed to be the way to go, with fire..
Then I came across this:


So I went to http://www.magicshop.nl/ in Haarlem and talked to Maurice. I got all the stuff I needed, flashpaper, flashcotton and a glow-plug. And a lot more, including a magic smoke machine that weighs only 200 grams.. And can produce a lot of smoke..
Great shop!

Then I went off to the hardware store for the rest. I created the fireball shooter, but I think I overused the flash cotton, it became a kind of canon, wow. It shot a pledget of flashpaper all the way across the room, without even igniting it. The bang deafened me for some time..
I think also my tube may have been a bit to long.
So, I tried a few other experiments. I'm not there yet..
After watching the instruction movie again, I concluded probably the secret is less cotton..



My fahter has been experimenting with making knee joints out of PVC-pipes, more about that later.

Scetch of the head

This is a scetch I made for the head of the dragon. Child1 came with the idea of making it's mouth dog-like in stead of reptile like. Reptiles don't seem so eager to bite, somehow. Maybe because we don't have any experience with them. So I went from a werewolf, added a little pokemon and then some komodo dragon.
Finally I decided on a cat's mouth and nose, because I have always thought a cat is a fat snake with paws, ears and fur.
Mariska and Tim both decided the dragon should be blue. It's a water dragon. I kind of like the contrast with the orange eye.
Well I did some material expression research, now I need to make this shape in 3D. Think I'll use organica, I'm one of the lucky few, who still has a copy.

We might have our first sponsor!

My colleagues and I were talking. If I get this to work, i'll be on the news...
So why not sponsor this project ourselves. Maybe I can get my material-cost back this way..
More details later.

But this thought just added an armor to the dragon, which might have the name of our sponsor on it.
Also in TV-interviews I would have to name ludatic a lot.

SLIGHTLY SPONSORED MESSAGE:

LUDATIC MAKES THE BEST DAMN INTERNET GAMES MONEY CAN BUY. They are fun and are suitable for the whole family. People will want to play them again and again!

The basic design

Now to see how the legs work together..


I hope you have a good computer, because clicking here will ask a lot of your flash player.

After experimenting with muscle-skins, I decided, this is the way to go.
I made skins for my legs and put 6 of them together, plus an extra one for the neck!
Now I don't know what the tail is going to be, but I want it dangly. swinging.. Something with springs or a system like those wooden snakes you get..
This is fun, I stayed up way too late, tomorrow is another day of hard work.. (YES, making games IS hard work!)

Got the legs working!

I have been considering the movements of the six legs of the dragon:

I did the hind leg. The underside of the curve isn't flat, but I have decided I will try for a little wobble... (click on trace bottoms to show the curve)

A variant to the hind leg for the middle leg. This is a tough decision. I tried out the front-paw movement too. This just looks better.
No real 6 legged mammals exist, so it's guessing all the way.
This one isn't lifted as high. The first back leg I had was kind of like a chicken. It jerked its leg up and then put it down real gently. It looked a little silly. So I used the evolution (randomise button) on it.
This gave me the middle leg. I averaged (by hand) the chickenleg and the middle leg to get the final back leg.


Now the front leg was a little harder. I had to get the reverse motion from the same wheel. I have been practising this with my arms in the mirror, so I had a pretty good idea of what I wanted. This comes very close.
All done within a day, who would have thought.

Model made out of straws

I tried this model of TJ's leg.
I made it out of straws, which I ran a wire through.
I hade to put three straws together every time to get a kind of "hinge" but now it's working fine.


I have learned a lot from making this model. Especially that I don't think I'll make my final model's legs out of pipes..
The joints are the problem. My father is trying to find a solution. I'm exploring other possibilities.
For the physics models it's easy to test with sticks. But for my next models I get 'skins' on the sticks to mimic the muscle model of prototype #9 (the youtube movie I posted earlier).

My father is in!

Now I just know this is going to work..

Tested The physics of my engine, I just want to make sure. So I put Theo Jansens (our Dutch Leonaro Da Vinci) theories to work, as he did before me. The machine from his scetches comes to life on your computer if you click here:


Seems like my physics engine is working fine..
I did notice the flatnes of the underside of TJ's curve.. Let's see if I can't make my model do something like that. Although I'm apprehensive about making it totally flat. After all we might be getting some rough terrain and a 6 legged dragon cannot tilt that easily..

The realism of walking with dinosaurs

Roy also pointed me to Walking with Dinosaurs the live experience.. WOW!
I like the detail and realism in the skin.
I think it will be to heavy for me to use rubber-cement, so I'm thinking of a patchwork of scales now.
But this is a very inspiring example, thank you ROY!

I like this bit, where they take a baby-rex suit into a mall!
I want this kind of reaction for my dragon:


The promo-video:

Considering the wheel

I also showed the preliminary model to Roy Tanck and he suggested I think of wheels.



The construction would rest upon 4-6 hinges taking my weight and the constructions weight when I 'ride in'.. This seems a bit much. As I currently weigh over 100 kilo's and allowing 25 kilos for the construction made of pvc's That is a lot.

The biggest issue (my weight) is solvable, so I'm dieting again..

The wheel concept was a interesting diversion. It steeled me in what I want. I want paws! Wheels on a dragon are just a bit silly, no matter how good you mask it.

Model to prove the concept

To convince my father (and myself) that what I am suggesting is actually possible. I made a physics model in Flash. This was surprisingly easy. I only used physics for games until now. The physics in games are never the same as in real life, which was the goal now.

You can see my first draft here. If you click on this link:
http://www.snoep.at/buildingdragons/drakenpoot2.swf you can see a moving version.
Sorry, I haven't found an option to embed flash-movies yet, so I'll do it like this.
If you click on the 'no skin' button and press it down you see the physics model.

Building dragons

I had an idea in my vacation period. It was called in my mind: "The dragon project". That blogname was taken, so it has become "building dragons"


I wanted to 'ride in' on a mechanical dragon at the next Elf Fantasy Fair (haarzuilens).






Because I'm not very good at building stuff, construction has to be simple
(I'll try to get my father to help me, he has tools and a shed an is very handy and creative).
I can't wait to get home and do some research (NO INTERNET HERE!!), but the basic Idea is there.
It was inspired by looking at a lot of examples, of people making variations of Theo Jansen's animaris vulgaris (or walking mechanism) in the past. One guy made a model out of plywood that worked. He used plates to suggest muscles. In my head I combined it with a paper-kinetic horse I once saw, it had a carriage, you could stand on, if you were made out of lego.. I just full-scaled that model to begin with. Later I got the idea for a dragon-bicycle, but it will be to hard to build for me..

So my wish is:


  • Ride on a dragon into the next Fantasy Fair at Castle the Haar.
  • If that doesn't work, guide a cool, full-sized dragon into the castle
  • If that doesn't work, maybe a baby-dragon is feasable?

We'll see what I'll be able to create..

Here is my inspiration for the project:

(The giants who's shoulders I'm willing to fall of:)



  1. Paper Kinetic Horse



  2. Theo Jansen




  3. Theo Jansen Leg, prototype #9 (ten sixtynine-rik)
