DIY-Constructions about animation
Hi! I'm Vaggelis Karadimas from vktoons!
Either you like cinstructions in general
or you're interested in animation and you look for equipment or relevant constructions
I'm your man!
So, today we'll learn how to make a thaumatrope.
It's a simple making.
But in this episode we'll focus mainly to a variation of the thaumatrope,
and on a problem for which we found a practical solution.
Thaumatrope was patented back in 1824.
It's a very simple making.
On a cycle disk, we draw on both sides two different but complementing drawings.
Then, with velocity we turn the disk and the two drawings appear as one.
The most known example is that of a bird appearing to be in a cage.
Though it's a simple construction, it presents the basic principles on which even today
is based animation and cinematography in general.
It is about the "persistence of vision"
and that is related to a property of the brain to restrain the picture for a certain period of time.
This is the element that allows us to watch movement and not static pictures
no matter if we talk about animation, live action movies or tv etc.
Worh "thaumatrope" has a Greek root and it is a compound one. It compounds from the words
"thauma" (pronounced "thavma" and means "miracle") and the word "tropos", from the verb "trepo"
which means "to turn", "to spin".
So, we can say that word "thaumatrope" means "the miracle caused by spinning".
So, we'll make three variables of the thaumatrope.
The two of them are easy. One of them requires more work.
First, we'll see what materials we'll need.
Scissors.
Cardboard.
White A4 sized paper, ideally of 60 gr weight.
Glue.
Punch.
Pencil and an eraser.
A marker.
Coloured pencils or crayons.
Rubbers.
Compasses.
A protractor and a ruller or a set square.
And skotch tape or paper tape.
First, the simple makings.
With the compasses we make four equal circles,
one on the cardboard and three more on the A4 paper.
Then, we cut the circles with the scissors.
With the set square or the ruller - what we have in any case -
we draw the diameter of the circles.
We'll draw the diameter in both sides of the cardboard.
In one of the circles we'll draw the drawing full, as we want to appear in the thaumatrope.
So, that circle we'll use it as an example for the other two variables we'll make.
So, that will stay here.
The example we'll use in all three variables is a flying rocket.
What next? We'll take our rocket drawing and we'll put the other disk over it,
we'll make sure their diameters to coincide
and we'll copy the body of the rocket.
We can do this better if we place the two papers on a pane with enough light
so to watch better the trace.
We follow the exact same procedure to copy the flames of the gas on the other paper.
We draw with the marker upon the pencil trace on both drawings
and then we erase the pencil trace.
Now we'll add colour on our rocket.
Then, we put our drawings on the cardboard and we make sure the diameters
to coincide with the diameter of the cardboard.
Also, we are careful, because we could make this mistake;
to put the back drawing right in the back of the front drawing, so the picture will be wriong,
that is that the rocket and the flames will fall upon each other.
So, we make sure the two sides to be in the right place.
Then, we glue them on the cardboard.
With the punch, we open two holes on the two sides of the diameters.
We pass the rubbers through the holes and we make a loop.
In the second variable of the thaumatrope we follow almost the same steps as in the first.
But when we reach to the point of drawing the back drwings, the gas that is,
when we are to glue on the cardboard our two drawings,
cause of the movement of that kind of thaumatrope will be not on the horizontal axis
but on the vertical,we must make sure that the two drawings will be one right behind the other.
The movement will be done like that and it will appear right.
After we glue our papers on the cardboard, we take a pencil or a pen,
skotch tape of paper tape and we stick with tape the pencil on the cardboard
- well, I cheated here; I took a component of a compasses -
and then with our hands we turn forwards- backwards and watch our thaumatrope.
The third variable is more complex. We'll try to show the movement of the rocket in an angle.
If we take the first variable and we say that in order to show the rocket in an angle
we'll just put the rubbers in another place, so to have an angle,
we'll find out that the two drawings are not in their right place.
So, we must see how can we solve that issue regarding the angles.
I'll show you then what I practically though to help us in that case.
First, in a bigger cardboard we'll make a guide
with the help of the protractor and of a set square or a ruler.
I have marked points every 45 degrees,
that is 45, 90, 135, 180, 225 270 and 315 degrees,
and then I joined them in the center.
But you can choose different degrees. So, you can make wider or smaller angles.
Then I create a circle of bigge diameter of the one of the thaumatrope.
What follows is the known; we make circle on cardboard and on A4 paper,
we draw, and we mark the diameters.
So, I prepared my drawings, according to the first variable.
I named the diameters of the two drawings as I wanted. I.e. 1a-1b and 2a-2b.
Next step; I take one by one my drawings and I place them on my guide.
I make sure that the diameter of th disk coincides with the 0-180 degrees line.
So, the first drawing show the rocket.
I turn it by 45 degrees
and I make sure the center of the circle to coincide with the center of my guide.
and then I'll mark a new diameter.
WIth a light hand.
The second drawing - which I stabilize it with the compasses on it's place
so to be more stabil - I turn it also by 45 degrees or
- if we focus in the flames - I turn it so that to fall to 225 degrees.
Here, I'll once again mark the new diameter with a light hand.
I name the new diameters differently than the first ones.
I.e. A-B in both sides.
I take the cardboard, on which I've marked the diameter as well,
and I put on the first drawing, making sure that the new diameter coincides with the cardboard's.
I also make sure that the point "B" of the one side coincides with the point "B" of the other.
We coloured, we glued and there is just one step more. We've done that before.
We open holes with the punch on the new axis now, the A-B one.
Nice! We pass the rubbers and we loop them.
And our thaumatrope is ready to spin!
So, all three variables are ready!
WE hope that you liked our cunstructions and that you found it usefull and funny!
In the comments field we expect you to write about your thaumatrope!
We expect your "like" to the episode and to share it so more will watch it!
