Custom

devices

Custom devices often need to be:

• developed quickly by a small team

• fully functional and usable

• self-contained

• usable in the wild

• able to be produced in quantity


The

SenseCam

project

• Wearable digital camera that takes photographs passively

• Camera with wide-angle lens, light-intensity and light-colour sensors, a passive infrared (body heat) detector, a temperature sensor, and a multiple-axis accelerometer

• Certain changes in sensor readings trigger photograph to be taken

The .NET Gadgeteer Platform

At the heart of every Gadgeteer project is a mainboard.

A mainboard is made up of a programmable processor (ARM7 / ARM9 /

Cortex M4), memory, and a number of sockets into which Gadgeteer

modules can be connected.

Modular hardware: mainboards

Sketching Ideas

The consumption of tea and coffee

featured heavily in our research so

many of these ideas looked at how

we might use ceramics to

encourage new conversations.

Design

Physical Inspiration

Gilding already present on the

surface of much ceramics.

We decided to experiment with its

use.
