W20 MARK 1 PRESENTATION

This week I presented the previous two prototype on Mark 1 presentation. I had my third tutorial with Polly. I did an experiment to test what elements fact the sound. I discussed with technicians Shawn and Malcolm in the workshop.

I aim to build a neck of a string instrument that can combine with any size and shapes of tins or cans. To reach this goal, I'm trying to find a way attach the neck with a tin firmly regardless of the size and shape. I've tried two kinds of method to do that. One is from the outside the other is from the inside.

• Mark 1 presentation and the feedbacks

1. How to preserve the tone when I expand the length of the neck?

2. Is the connecting area effect the sound? 3. Don't trap into this problem try to find an easier way or change the requirement to acceptable difficulty. Mind the time.

I did a sound experiment to find the answer to question 2. The experience of learning classic guitar gave me knowledge about the structure and how each part of a guitar will affect the sound.

But I decided to keep trying to find a perfect way to make it applicable for all sizes and shapes.

• Sound experiment

I made a quick model with one string to test how these elements below will affect the sound:

1. string length 2.the area of the connecting point 3.is the surface been blocked or not 4.tins

The results are the material of tins affects the sound the most. The more ductility the tins are, the better. The surfaces been blocked sounds much worse than those not. The connecting area hardly has effects on the sound.

• Tutorial

We discussed:

1. The improvements I made compare to prototype one. 2. The problems of my prototype two. 3. The experience.

Her recommends:

1. Start to think about aesthetic and the form of it. 2. Discuss with technicians for help.

We agreed:

1. Keep solving the problems and explore other methods. 2. Start to think about aesthetic and the form of it. 3. Make another prototype.

• The talk with technician

I've been working on my own. Probably another education different from my home university to here. In Beijing, we are encouraged to develop our scheme to a particular stage then we are expected to talk with our tutors. Usually, they will point out the not that promising ideas quite straightforward. And ask us to give up it all and make something better from the very start. I get confused as I got no critical comments here. So I've been working alone trying to develop some ideas first. It seems design process here is not like that. Shawn and Malcolm showed me some tools to refer their mechanical theory.
