The assignments for wk17 were as below;
This week, we have to propose a final project that integrates the range of units covered, answering the questions below;
1) what will it do?
Lost property prevention attachment can let us know by beeping if we leave the property without taking as below. I want the attachment to connect the application of smartphone via bluetooth or iBeacon. The application operate on the background of the smartphone, and beeping if the smartphone gets apart from the attachment to a certain distane (eg. 5m, 10, or so).
Main functions are:
2) who's done what beforehand?
I got inspiration from several kickstarter's project as below:
Though there are several examples like above, I decicded to make the device for the purpose of improvement for my digital fabrication skill and understand its limit.
3) what materials and components will be required?
With help of Emma, our local instructor, I broke down the project into small tasks/component
Structure of the device
4) where will they come from?
Most materials I used came from the Fablab Amsterdam inventory.
I only bought 9V small battery outside the Fablab.
5) how much will it cost?
Below is the BOM (bill of material) of my final project. It cost 56.5USD totally.
Bill of Material(BOM)
6) what parts and systems will be made?
7) what processes will be used?
8) what tasks need to be completed?
Mainly same as Question 7) what processes will be used?
9) what questions need to be answered?
10) what is the schedule?
I have remaining two and a half weeks until final presentation and already made Fabkit board.
So first, I tried to finish the electriacal part; input and output module, and power supply issue. It will take 1-1.5 weeks. After that I will make machanical part; 3D modelling because it is vital part for final presentation, whose process will take 0.5 weeks. Finally, I will tackle networking issue, which will take 1 week or so, however, this is optional for my final presentation.
11) how will it be evaluated?
The system should be able to respond to the motion from others when someone tries to steal the item which the device inside and sound if item holder apart from the device over 30 meter or so.
