Our group, Team Technology Taskforce, focused on researching subjects relating to technology. We made a list with possible research subjects and assigned team members to each subject, resulting in small groups of one or two people doing research on a particular subject. Our results are available as PDF documents at the end of each subject summary. An overview of the subjects we researched can be found below.
One of the research subjects was the use of light sources in our installations. Because most of the installations will have some form of light output, this knowledge would be useful when a light source has to be selected or different light effects are being researched.
The aim of the research was to create a simple overview of some different light-sources that might be a good option for the installations later on in the minor. There are more options than simple LEDs and light bulbs and this overview should give the users more options to choose from. Of course there will always be more options for specific designs that will require more research, but this overview should be a decent starting point.
The sheet gives an overview of several light sources with their own pros and cons, colour properties, power usage, controls, an indication of the price etc. Bases on the needs of an specific design, a type of light source can be selected.
Another part of our research was sensors. Instead of focusing on the sensor itself, the focus is on the possible uses you could have for a sensor and gives a suggestion on which sensor you might want to use for that, complete with description, output, difficulty and price. Because the sensors are most likely being used with an Arduino, all the listed sensors are ‘plug and play’, no soldering required. An example can be seen below.
This part is coming soon.
Another part of the research was soundscapes: what they are and go about to make one. What a soundscape is, is quite simple; it is the sound of a specific location. According to Canadian composer R. Murray Schafer a soundscape consists of three main elements: keynote sounds (sound of nature), sound signals (for example warning devices) and soundmark (sound unique to a location).
To anwser the question of how to make one, is a different one entirely.The search started with Wolfram Tones, a random music generator based on a certain set of rules. The sound coming from this tool was very unpleasant, so it was decided to try and make one in Ableton. I tried to copy the rule based generation of Wolfram Tones, by using randomizers and sidechained noisegates. To keep the whole composition in key a scale tool was used.
We researched fabrication methods in relation to materials. The focus was on production methods that can easily be used within the minor.
Within the TU Delft there are a lot of machines available. At Protofab (CNC miller and laser cutter), BK (3D printers, deep drawing, CNC), IO (3D printers, metal sheet forming, materials) and DEMO (a lot of different machines) we are able to do almost anything. And even if it is not possible we can always look outside of Delft (ie. RDM & FabLab).
When choosing materials the fabrication methods play an important role. Not only take the processing time into account, but also the amount of pieces used and material costs.
