SFX – Research material: Freddie Wong

We had just started the Special Effects module and we are looking at video composting and I came across this awesome guy called Freddie Wong who does special effects in videos and seems to be quite and expert in composting and tracking. Below is one of the videos that I really liked.

I find him very inspiring and he has given me loads of ideas and it is really interesting to see how he puts the videos together.

Experiment: 2-Axis Gimble

To create 2 of my projects (Painting and Eye Box) I will need to move an eye (or 2) using servos. I done some research on 2 different methods to achieve this, the 2-Axis Gimble and a Universal Joint. I decided to try using the Gimble method. The reason for this is because it seemed the easier of the two for me to create as the universal joint requires more materials for me to obtain whereas the gimble I can make using the polymorph plastic.


Professial practise – alot of people

ok after my post of facebook asking if anyone wanted a website i had 4 replys

1 someone i know wants to set up them selfs as a younge activey trailer and wants a website

another a gaming forum comuity and one guy wants me to design his portfolio

the last was a friend of a friend whos mum is is a singer and wants to promoto her self

that last one sounds promising im going to get her number and see if i can call her

Making the eye

For 2 of my projects I will need to use an eye that I can attach to servos and move. To start off I used a dolls eye as it was already made and looked realistic. Then I just needed to make a backing for the eye so that it can be attached to the servo and I wont need to damage or make holes in the eye itself. For this I used something called Polymorph plastic which is tiny little plastic beads that when you place them in hot water then soften to a putty like state and can be molded into any shape or form and when cooled down becomes solid again. This is extremely useful for building projects like mine.

I created a backing on the eye that is almost a rounded cone shape and has a hole going down the middle vertically so that it can be attached to the gimble using a metal rod.

Here are some development images.






Research: Moving eyes

For 2 of my projects I want to use moving eyes however in order to find the best way to do this I had to do some research. I searched around and looked at various methods and suggestions from other Arduino users and professional animatronic creatures. This is what I found.

Axis gimble

This can be done either as a 1-Axis or 2-Axis gimble. This is basically a frame built around the eye that holds another circular frame secured loosely by a pin on each side allowing the inner frame free movement to spin. The eye is then connected to the inner frame using a pin going through the top and bottom of the eye. This allows the eye to rotate on a vertical axis to move left and right, coupled with the inner frames abillity to move up and down you get full freedom of movement. The eye is attached to 2 servo’s, one to the top / bottom of the eye the other to either side. As it pulls and pushes it moves the eye. This seems like the easiest method and perhaps more stable as its all held into place.

Animatronic Eyes Test (Gimble)

Universal Joint

This is done using a universal joint which allows freedom of movement to what ever it connects to. To use this you need to connect one end to a stationary frame holder and the other end connects to the back of the eye. The servo’s then connect to the top/bottom and either side of the eye and push and pull in the same way as the gimble. It looks simpler but requires extra items such as a suitable rod and the universal joint itself. This looks a little bit more natural and perhaps easier to hide behind a box as it doesn’t take up so much space.

Experiment: Servo position test

While working on the servo’s to control the eyes I cam across a really useful sketch / code that allows me to set the position of the servo and hold it there so I can line the servo up how I want it and know where each number I enter will move the servo. For this sketch I used the Sweep code that came with Arduino and got rid of the part that makes the servo move left and right continuously and kept the part that just writes the position to the servo. This meant whatever number I assign to the variable “pos” it would assign that position to the servo.

// Sweep
// by BARRAGAN <http://barraganstudio.com>
// This example code is in the public domain.
#include <Servo.h>

Servo myservo; // create servo object to control a servo
// a maximum of eight servo objects can be created

int pos; // variable to store the servo position

void setup()
myservo.attach(10); // attaches the servo on pin 9 to the servo object

void loop()
// Sets the servo to the stated position. Helps track positions.
pos = 120;

Prossial practise – found some people

today i went around my local town and called up some bussiness that had adds in the windows of shops one was crafty cards a women running her own small bussiness she seemed very intrested

another was trek cafe for younge people who seemed equaly intrested both asked me to call back

also iv posted up on facebook if anyone who promoting them selfs as a bussiness or freelace wants a website

Professional practice – find a bussiness

wev been given the task of finding someone to design a website for who has a bussiness iv been looking at local bussiness like Gavantiques based on epsom the bussiness that sellers antiques

also and mingo fish and chip shop maybe try designing a website for them

also contacting my old school notschool.net see if they want a website

im going to talk to them tomrrow
