PRODUCTION SUMMARY

Learning Outcomes

• Create your own integrated design.
• Demonstrate 2D & 3D modelling capabilities applied to your own designs.
• Select and apply appropriate additive and subtractive techniques.
• Demonstrate competence in design, fabrication and programming of your own fabbed microcontroller PCB, including an input & output device.

• What is it? And what will it do?

  This is the first complete, fully integrated prototype version of this project. As a proof of concept, this bracelet includes 1 sensor (3 axis accelerometer) and 2 outputs (RGB LED and a haptic vibration motor), which activate based on erratic movements of the individual wearing the bracelet. Future spiral developments will include more sensors measuring other physiological parameters and different methods of feedback for the users.

  Simply put, the motor and RGB LED will react to extreme or erratic movements. This is a physiological symptom of a deep emotional state. The primary driver for this project was to help those individuals with emotional dysregulation. A condition that causes the sufferer to retreat into a ‘Fight/Flight or Freeze’ state of mind at the slightest stress trigger. Unable to perform executive functioning or rational thought at that time, the bracelet will (hopefully) give enough stimuli for the wearer to realise the state of mind they are in and help bring them back to higher brain functioning. Therefore allowing them to deal with the current situation and or any other associated conditions correctly.

This is not representative of the unit cost per device. The cost of making the moulds would be spread across it’s lifetime of use and the amount of individual silicone bracelets cast from them.

As the purpose of my project is for the benefit of others I will share everything (design files, code etc) for others to easily benefit from. I will at least expect an attribution for recognition of the work I did from which they are building upon, as defined under the Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) license.

CONCLUSION

From the start of FabAcademy to this point, I think I have demonstrated how far and how much i have learnt in this time, by creating this complete, integrated and working project. The combination of processes and skills needed to create this project testify to the breadth of knowledge and experience i have gained whilst studying at FabAcademy.

I consider this to be a ‘ground zero’ point from which my learning to make (almost) anything (and fully integrate them) will continue. Something I was unable to do at the start of the study.
