18. Project development¶
Assignment¶
Complete your final project, tracking your progress:
- what tasks have been completed, and what tasks remain?
- what has worked? what hasn’t?
- what questions need to be resolved?
- what will happen when?
- what have you learned?
What task have been completed, and what tasks remain?¶
completed:
- 3D printed body
- neopixel controlling
- photo transistor
- wireless power supplying system(using existing kit)
- using BLE beacon as a proximity sensor
remained:
- mesh networking (painlessMesh)
- control the color of LED by BLE beacon tag
- make smooth body by wet sanding with epoxy resin
- or making mold for the body and do casting with it (retry)
- decoration for power station
What has worked? What hasn’t?¶
worked:
- 3D printed body was output better than I expected
- Neopixel and photo transistor are working
- wireless power supplying system(using existing kit)
- using BLE beacon as a proximity sensor
not worked:
- each devices should communicate each other by mesh networking (painlessMesh)
- tried to control the color of LED by BLE beacon tag but couldn’t read the data properly
- making mold by 3D printer but the material liquid leaked from the gap between each layers and body and mold made adhesion
What questions need to be resolved?¶
-
can meshNetworking library be used by 1100mAh battery? seemed too much power consumption was the issue not to activate the program.
-
how can I read the information on the Advertise of beacon properly? I got expected data and unexpected data in turn.
What will happen when?¶
- 4th July. the outcome of final project have done
- 7th July. finish presentation slide and video
- 8th July. presentation
After finishing all the weekly session, I set a precise schedule to give my final presentation on 8th July.
In the actual process of the project, though some parts were related to the weekly assignments I already finished, I couldn’t use them directly to my final project. So I needed to modify them especially in programing part. The work was 3 days behind schedule when I had prepared all the parts for assembling. Then, I did my best to finish the rest of the tasks within 3 days and it had done somehow. I learnt that It was really difficult to control long schedule and it needed frequent updates each time the delays had happened.
What have you learned?¶
- how to use digital fabrication machines
- getting used to 2D and 3D design software
- the process to cut something by machine (lots of them have similar system)
- how to make something from planning to manufacturing
- become possible to imagine how I can make almost anything or what I should research
- basics of programing ideas
- electronics design and production
- the way of documentation and how to use git(lab)
