This week our main focus was building the platform. On Tuesday we met with Navid and discussed about the most recent design of our base platform and the progress of the PCB board.

We redesigned our platform a couple times from Monday to Wednesday and our wood arrived on Tuesday. We then talked to the Mark from machine shop about the building of our platform. We submitted a ticket and with a couple back and forth with Mark the platform is now underway to get made.

Currently we are waiting on the platform and to calibrate the load cell, and cutting some edges on the platform to make better fit for the load cell and circuits. PCB design is also moving forward with changing the design for the wires to not overlap.

On Tuesday, we met with Navid and were given some help with the PCB design and circuitry:

– We will be using extensions for the LCD Screen and other components to have better placement in the circuitry box

– Possible new programs and ways to design the circuit on the PCB board

We also got to meet with a professional mechanical engineer who looked over our design and gave us many ideas.

We took the Machine Shop tutorial on Wednesday and got some more feedback regarding our design. We have decided to make the base out of wood and have a sheet of steel on top of it.

We completed the platform design on Solidwork and will be obtaining the materials this weekend and possibly finish building it by the end of next week.

The addendum is finalized and has been sent.

The tasks for this weekend have been assigned:

Maria will be buying the wood and get it cut to size for the platform

Oscar will be finalizing the base design

Michael will be drawing the enclosures for the circuits

Mustafa and Weng Fei will be making the draft schematics in Altium

On Tuesday January 6th, our group met before the meeting with Navid and started planning out the second prototype. Some designs of the platform were introduced and discussed. During the meeting with Navid we went through our thought processes with him and were given some ideas on how to approach our problems.

On Thursday January 8th, a change of scope for the project was discussed and came to a conclusion that we will mainly be focusing on the base of the platform and the electrical components for the second prototype, and more can be implemented in the final prototype if the time allows. We ran through the idea with Cristian and Navid, they agreed with the idea and an updated proposal and a two pages documentation will be written.

We divided up the work after the meeting where Oscar and Michael will be working on the platform, while Mustafa, Maria and Weng Fei will be working on the PCB and electrical components.
