The team designed the cooling system using peltier. The cooling system is utilising tubes to carry out water or air. The photo showcases the designs. It may need to be reworked due to the bending around the tubes which worsens the flow of the fluids.
The team consulted with the lecturer and decided to move the sensors to the shoulder straps.

The team did some tidying up with the arrangements for the wiring and placements of the strip boards and drives.
Discussions for the peltier design were ultimately simplified to just blowing cooled air into the brace as it is not under the requirements of the project.
Further stitching will be done to ensure that the product works without any tape or other adhesives that can be removed.

The team found out an issue with the sensors and the code. The top sensor is still loose and so there is a need to shift the position to a more rigid location that is at the top.
The code has to be rewritten due to an increase in the number of sensors used. In addition, the accuracy and application is not ready as of yet. Thus more testing is required.
The team also worked on the slide presentation that is coming on 4th Jan 2019. This slide presentation is to showcase the technical aspects of the project, from the design thinking to the prototyping.

The team worked on the code and redoing the sensor. There is an issue with the bottom sensor being too flexible, moving it with the top. Other than a need to restrain the motors, there is a need to restrain the bottom sensor holder.
Code has been improved for more accuracy in readings.
Testing of elastic straps for the semi-rigidity and elasticity required for the brace has been done and it requires 3 layers of elastic straps. Why this material was chosen was due to the ability to stretch and act as a solid while not being unpleasant to touch.

The team went to rectify the issue of the bottom sensor being able to move too much by attaching a belt to the system. This helps in adding a secondary layer of securing to the body tightly and improves the performance of the device.

The team has worked on the product with the final assembly done. The electronic testing with the code will be more efficient without the need to have the wires hanging loosely.
Coding is still undergoing testing phases

27/12/2018
The team tested the code with the product and got the code to be finished. The team also worked on the presentation slides for the upcoming presentation.
Report will be updated to reflect on the progress made over the past month.
There will not be an update for the 28th Dec 2018 due to members being overseas and attending other events.

The team found an error with the electronics as it is only calibrated well for one member of the team, and not for other usages. This, along with the motor testing, proved to be difficult to implement.
There was an issue identified from the sensor when held vertically causes a glitch in the reading. Calibration had to be done to improve the reading and prevent the glitch from occurring. One of the sensors had loose wires, thus for security the wires were all re-soldered on that sensor.
The code will be reworked to be prepared for the mid-term presentation. In terms of the presentation, the team has refined and practised presenting the content to others and updated the slides based on their feedback. More practice will be done

The team went to test the works of the product and the material had experienced too much stress and breaks. There will be a need to reprint and increase the thickness of the outer layer.
The slides and report have been reworked to cover as much details as possible from the past months. The team will improve the timing to fit to 10 minutes.

The team troubleshooted the product and found out some issues with the device. The current draw from the device is high and with the usage of only one battery pack will be insufficient for accuracy. There is a greater need for a separate battery pack designed for the product.
The team are practising for the mid-review presentation that is occuring tomorrow. The presentation is within 10 minutes and satisfies all components of the requirements.
