The world needs your light....
Meeting started at 2:00 p.m. at Ngee Ann Polytechnic
More practice was to be placed on the Labview programme. Mr Lee told us that we are not just going to focus on labview, but also to dismantle a projector and take down the dimensions and lastly coming out with a diagram of our prototype if time permits.
Firstly, we practised Labview, starting with the design of a Shift Register circuit, which was highly successful, just on the first try. We also made use of the Elasped time function so that the program does not execute too quickly and is only executed in a set period of time. A pink wire attached to the elasped time symbol refers to a STRING. We also made use of While Loops and the Compare Function; once the output reaches a certain value, it will automatically reset to the original.
Next, we decided on how we should modify the projector to be used as the product of the experiments. Tasks :
1 ) Design blueprint of the prototype
2 ) List down all required appratus needed, with specifications if possible
3 ) Calculations for focal length etc. using the lens equation to ensure proper positioning of the lenses.
Our original design was to put everything in a rectangular box measuring 45 cm X 20 cm X 16 cm. However, we decided that this was far too original and uncreative and was too bulky as well, and soon rejected it. We left the designing stage to the next session.
This is an image produced by that of a conventional image projector :
