13. Applications and implication¶
What will it do?¶
Concept:
My idea is to build an alarm and vibrate system for correct the posture . when the pack is pending while setting on the chair or somewhere the system will start making alarm and vibration to warning the user
If the hump is more than 25 degrees
instant vibration reminder, automatic vertical muscle implantation.
What will you design?¶
In this project I am going to build a system can interact with the user who suffering from back and neck pain to alert them when bending to relieve and avoid that pain.
I am going to design the following stuffs :
-
PCB board Input/output (Input: Flex sensor, Switch / output: Vibration motor, speaker, Led) >> [PCB DESIGN]
-
PLA 3D printing box covering the Electronics parts.>> [3D-Printing]
-
IN addition If I have a free time I will fabricate the shoulder corrector using CNC0 and swing machine.[material]

What parts and systems will be made?
I am going to design the following stuffs :
-PCB board Input/output (Input: Flex sensor, Switch / output: Vibration motor, speaker, Led) >> [PCB DESIGN]
-PLA 3D printing box covering the Electronics parts.>> [3D-Printing]
-IN addition If I have a free time I will fabricate the shoulder corrector using CNC0 and swing machine.[material]
What processes will be used?
-
For PLA 3D printing box for the Electronics parts, I will use 3D modeling and 3D printing.
-
For the board I will use PCB design and PCB milling.
-
For Shoulder corrector I will use CNC laser cutting and swing machine
What questions need to be answered?
On the coming weeks I need to find out how to check the best degrees of bending to calibrate the system on it and if there’s any noise signal effected by the distance between the electronics parts on the arm and the flex sensor on the pack.
How will it be evaluated?
Evaluation through project development: I will test subsystems before connecting them together. For example, I will test the degrees that coming from the flex signal to Microcontroller and check if it the best values it’s required.
Evaluation after project development: I will use the system in different CO levels environments and check the response.
