The Switch

Timer=variable resistor=potentiometer or 'pot'

Information found on

• Thinkquest
• Wikipedia

Construction of a wire-wound circular potentiometer. The resistive element (1) of the shown device is trapezoidal, giving a non-linear relationship between resistance and turn angle. The wiper (3) rotates with the axis (4), providing the changeable resistance between the wiper contact (6) and the fixed contacts (5) and (9). The vertical position of the axis is fixed in the body (2) with the ring (7) (below) and the bolt (8) (above).

Disassembly Structure

I'm working on a mindmap including all parts, connections, material specifications etc..

Of the HEMA toaster I'm working with.

This is what I have so far!

What's on the market?

Anno 2010, a lot of innovative toasters exist.
However, it is mostly, considering a few exceptions, the 'packaging' that changes

while the techniques that are used as well as the materials remain pretty much the same.

This is a pwp with a thirty random examples.

Deconstructed video

I found this interesting video on the DECONSTRUCTED website

on the working of a toaster

Go check it out!

note: you need to sit out 30seconds of advertising before the video starts

Where to start..

my first step is checking out the website 'How Stuff Works'

Let's see how they can be of use to me.

I have made a mindmap of their information with some links to pictures of theirs, unfortunately

on this blog I am not able to share these links, but I've put them here plus they're all pictures from the 'How Stuff Works' website so you can find them there if you'd scroll a little!

Assignment

Hi!

My name is Judith Lievens and I'm an Industrial Design student attending at the College University of Flanders in Kortrijk.

welcome to my blog, which will treat of the technology of a toaster.

On this blog, I will post every bit of information I can find ending with a presentation dealing with all the problems, choices and interesting details explaining the technology of a toaster.

I will tend to explain everything in such a way that 'dummies', meaning those who aren't particularly familiar with technology will understand everything as well as pro's.

Enjoy and learn!
