TEST 1

Original Test

To begin we reran the original controls. 

 

REFLECTION

+ Works well

– Boring to use, not very exciting

– Switches are difficult to use as too small and close together.

 

TEST 2

Using Paint to the X axis controller

By creating a straight line and placing the 5V wire at one end and the GND at the other/ the middle wire (A0) is held.

 

REFLECTION

+ Works well

– Still only 1 off the board

– Couldn’t use the whole screen

 

TEST 3

Using paint for the X and Y axis controller.

By replicating the same process as before for the other controller. this created reading for the Y axis s well.

 

RESULT

 

REFLECTION

+ Works well

– Wouldn’t always use the full screen

– Was very jumpy, didn’t draw in straight line as it did before meaning the image would be distorted.
(however, this could be a good as it makes it more arty/ abstract, giving the piece some originality.)

 

TEST 4

Making the paint controllers circular

By simply drawing the paint into circular shapes and applying the wires in the same way.

 

RESULT

REFLECTION

+ Works well

+ Bigger range across screen

+ the shape of the controllers are more representative of that on an original etch-e-sketch

– Still Jumpy

 

TEST 5

Using 2 people to control one axis

Person one; holds middle wire and person 2’s hand

Person two; holds person ones hand and moves their figure across one of the controllers

(test around with having to hold the wire connected to circuit.

RESULT

REFLECTION

+ Works well

+ Bigger range across screen

+ Fun and requires co-operation

– Still Jumpy

 

 

REFLECTION 

The paint has been inputed into the circuit well. The shape makes it more representative of the old style as well as more responsive on the screen.

The controllers are still quite small though.

one other concern is that the middle wire requires it to be held to draw. This may be an inconvenience to the person using it.
