Style Animations shown on wall

Below are two video clips, one of the silhouette animation (left) and other is the line-drawn animation (right). The animations are shown on an image of the previous wallpaper cutout experiment. I have created these two small animations to see which style technique will work best for the animation when being projected onto the walls.

From both video clips, I think that the silhouette animation works better with the wallpaper cutout. Therefore so far I think I will stick to the silhouette idea for the animations. I will try a few more short animations and see if they work well too.

Style idea for the short animations

Over the last few days, I have been working on one of the small animations that will be projected onto the wall. The animation I have been working on a simple animation of a bird flying from one side of the wall to the other.

When thinking of which style to do the animation in, I had to make sure that the style would work on the wallpaper cutouts that would be pasted onto the walls.

I first tried to do a simple line drawing animation.

Here are the frames I designed to create the animation. I chose to create the short animation in only 9 frames.

This is the animated version of the above frames.

I am unsure about this style technique and therefore thinking about the wallpaper cut outs on the walls, I thought about creating a silhouette animation and see if it works better than the line-drawn animation.

Here are the individual frames for the silhouette animation:

This image below shows the motion of all the frames and how it would form into a smooth animation.

Here is a video clip of the silhouette animation:

As you can see that this animation does work well. I will need to test this on the wallpaper cutout and see if that works well too.

Solving issue: PROGRESS

We have tested the platform to see if it works before attaching the ball-bearings and it works successfully.

Here is a video footage of the working turntable:

However, the platform is slightly unbalanced and does rattle too. Therefore, I just placed ball-bearings in freely to see if it would make any difference.

Here is the video footage showing the ball-bearings:

Once I have placed the wooden rings in place as previously mentioned this self-made turntable should work successfully. The final touch of this production is to make sure that it will be able to handle the weight of the projector. Therefore as a tester, we placed a laptop on the platform to see if it can handle the weight.

Here is the video footage of the laptop tester:

As you can see from the above video that the turntable is working successfully. As my next step, I will attach the ball-bearings and wooden rings. Once this is complete, we will test it again.

Building Platform

Over the last week, I have been building a platform that would allow the projector to sit onto it and rotate when required to. Here are a few images of what I have come up with so far.

The image below shows the bottom of the platform where the stepping motor is. The stepping motor is attached to the bottom board with 4 machine screws and nuts.

The 4 machine screws are also attached to the bottom metal plate. The metal plates in the centre has bearing balls allowing the plates to rotate. I purchased this from B&Q, it is used to rotate a TV once it is attached to the TV stand. However, because it has a weigh capacity of 150kg I only need it to hold approximately 3.5kg. Therefore, I thought it would work for my purpose.

This is how the top of the platform looks. I have attached another board to the top, this is where the projector will sit on. When using your hand to spin the top board, it has enough friction to spin without using any strength which is very good as the stepping motor I am using is only 12volts.

Because I have the steel plates in the centre of this, the top board is slightly unbalanced. Therefore to overcome this issue, I will be making two inner wooden rings placed around the steel plates in which I will place bearing balls allowing the board to spin with balance.

My idea of the two inner wooden rings are similar to the traditional way of handing making embroidery. I will be creating something similar to the wooden frames and attach them to the bottom board, leaving enough gap between the rings to place the bearing balls. However after speaking to some people, I have been told that this way would cause more friction and whether the 12volt motor will be able to rotate the top platform.

I will be speaking to my tutor about this today, and also test the platform without having the bearing balls attached to the board.

Solving issue: Rotating Projector PROGRESS

This is the next step as previously mentioned.

The image below, shows the setup of Arduino and a slightly more powerful stepping motor.

This is a video footage of the stepping motor working successful. As the stepping motor only has a pin, I have attached a piece of white paper to show that it is spinning.

The next step is to build a platform which will sit on the stepping motor and allow the top platform to rotate.

Solving issue: Rotating Projector

Over the past couple of weeks, I have been trying to solve the issue about how to rotate the projector. These are the results so far for the 4 ways previously mentioned.

1> Using a turntable motor:

I spent a good few days looking for the complete turntable motor or something similar, however I had no luck. I did come across record-players and deck turntables, however these were from £200 - £400. It would be cheaper if I just built one therefore this way is discontinued.

2> Using a stepping motor and build the platform:

With help from my tutor, I have managed to get hold of a stepping motor. The next challenge for this is to build a platforms that would rotate via the stepping motor. This way is still in progress.

3> Using a windwiper motor and build the platforms:

I went to a few places in search for a windwiper motor. However, I was unable to get hold of one therefore the way is discontinued.

4> Build the whole thing myself, using a drill as a motor:

This way is still in use at the moment. If the stepping motor does not allow the platform to rotate, I will use the idea of using a drill as a motor in order to solve this issue.

From the above list, ways 2 & 4 are still in process and therefore I have a good chance in order to solve this issue.
