The team went to stitch the extended fishing wire holders and attached the fishing wires to the motors and tubes. Most of the assembly is complete except for the strap adjustments.
The electronics have a connection problem. Most probably with the multiplex board connection. Troubleshooting will be needed, and the programming.
The slides have been evaluated and there may be a need to change the formatting of the presentation to have a hook and a skit.
The receipts have been evaluated and will be reimbursed back.
Reports have been looked through and will be improved before the final submission date

The team did some touch up on the stitching and preparation for the final assembly such as the velcro on straps and the fasteners.
Under the electronics, there is a redesign of main board and switching the pins around to improve compatibility
Additions of detachable connectors to all boards to improve modularity and ease of testing.
And the created power distribution board
Currently there is a need to test the board and debug if needed
Tools will be brought the next day for final assembly
There was a consultation with the SUTD mentor and she gave good feedback and criticism on the slides and how to improve on it

Day 53
06/12/2018
The team finished with the final assembly of the mechanisms. The soldering and electronics has been finished for the presentation for the next day.
The report has been looked at and revised heavily to include every detail that is constructive from the blog.
Motors have been tested and it was effective in applying the force required to straighten the back without giving too much discomfort.
Presentation was practised for the Design Odyssey pitch for the next day and the team worked with the updated slides from yesterday's feedback.

The team went to present for the Design Odyssey pitch and won Best Speaker Award. The judges said that even though they may not want to buy the product (as they felt they are not the targeted audience), they are interested in the product and presentation.
Feedback was provided to improve the products' sales and appeal, but overall the presentation and questions answered are well done.
The team was approached by the head of Engineering Academy for future opportunities. The team will be focusing on testing with the sensors and products for the next week.

The team made a Gantt Chart to track the teams progress and made updates to the report. Discussions were made on the future plans of the project and made sure that the timetable is reasonable for each member.
The team also submitted the report to the lecturer.
The google drive has been updated to be more formatted and improved, with some old documents and images to be uploaded into the google drive
Motor driver board was changed to an l298n board to reduce size.

Day 56
10/12/2018
The team tested the sensors and motors together.
There was a error that occurred where the readings that were reported were incorrect and seemingly random, however the team has not been able to cause it to occur again.
Things to work on:
- Timer to unwind after a period of time has passed after activation
- Find cause of error and fix it
From the video, the brace has a problem with the material being pulled and buckled. There will be a need to improve the design to stop buckling.

Day 57
11/12/2018
The team tested using multiple sensors together.
The sensor reading errors from occurs more frequently when multiple sensors are used
The cause of the error seems to be caused by the connection between the sensor board or the sensors themselves. Further testing was done and it was determined that the actual cause was the length of the wire causing interference.
The wires connecting the sensors were cut and re soldered to be shorter to improve aesthetics as well as ensuring a more reliable connection
The team planned out the wiring path and placements of the electronic board, and also ensuring space for other components to be attached.

The team reworked on the code and found some formula errors. The code has been updated and had gone through troubleshooting. There is still room for improvement but as of this blog update the sensors follow the code:
The CAD is under works as of this blog update

Day 59
13/12/2018
There were some issues with the material being too flexible and causes sensor inaccuracy. Rework will be needed for the design to prevent inaccuracy with sensors and to fix the other issues that are there.
The code is still undergoing troubleshooting testing phase as of this blog post.

The code is still undergoing the testing phase but more progress had been made.
The blog had been updated for easier navigation and lesser loading time. The blog posts are segmented by sets of 10 days.
