I was inspired by first moving image devices. The phenakistiscope was the first widespread animation device that created a fluid illusion of motion.

Zoetrope

. The praxinoscope improved on the zoetrope by replacing its narrow viewing slits with an inner circle of mirrors, placed so that the reflections of the pictures appeared more or less stationary in position as the wheel turned. Someone looking in the mirrors would therefore see a rapid succession of images producing the illusion of motion, with a brighter and less distorted picture than the zoetrope offered.

I am making a reverse praxinoscope, which creates moving image on the walls. The animarion and model was made using Blender.

My systems diagram includes two gears wich are connected together with a pulley. For the motor I chose Adafruit 4416 which runs with 7.5 V and the speed is 400 RPM.

I designed a rotating device in Rhino. The top plate includes screens on which images will be placed.

I got my motor to work, forgot to take nice photos and videos. Decided to make a circuit board later (big mistake).

The base I decided to cut from 1/8 chipboard and then spray paint it. But it was unstable. Plus I forgot that I need the dpsce for pulley below the top part and some of my legs couldn't fit in. Also I realised that I had to screw all the parts to creat the tension.

This was my updated 3D model. I 3D printed the base too. It had to be made in a parts so it could fit in 3D printer.

Old and new.

As I didn't understand how to calculate the tension and the distanse between gears (I also didn't know the size of pulley I had), I screwed everything on eye/.

This was my updated 3D model. I 3D printed the base too. It had to be made in a parts so it could fit in 3D printer.

Works! Very loud because of the rollers that help the plate to rotate.

My screens, made from acrylic, started falling apart as I increased the speed from 200 RPM to 400 RPM. Before, I tested a lot of options on how to fix screens on plates, it seemed to work on drafts, bt at the end the connection was not strong enough.

Still works! Very loud because of the rollers that help the plate to rotate.

I wish I could spend moe time om designing the animation itself. Another problem was that tha case that was holding motor vertically was tilting towards the plate and sometimes I had to hold it or fix it.

I was even thinking to make a 3D printed animataion. I found a loop animation of a girl walking. In Blender I baked each frame and had 24 models of a girl. But I forgot that the scale of the model will be very small, so when I tried to print one figure, all the details were lost (hands, fingers, etc). And one figure took me 1 hour to print.
