     From the work period of December 11, 2023 to February 3, 2024, Seal Team 6 has completed milestone 4 task 4b. In task 4b, multiple revisions of the bills of materials (BOM) and drawings were sent and revised with the client Schlumberger (SLB). The team is currently working on BOM revision #3 and document drawings revision #3. During the winter break, the team received 90% of the materials for the project (such as the aluminum extrusions, heating band, PID controller, etc.). Some of the members met at Jamar's Murry, the UH machinist, workshop to create tap holes in the aluminum extrusions to assemble the frame structure. Currently, the team is working on task 4c with an expected deadline of 2/18/24. In task 4c, the inner components of the compression mechanism need to be sent to the SLB machinist to be machined and attached to the aluminum frame polymer spring testing device (PSTD). 

        For the work period of February 4 – February 17, the team plans to continue work on the assembly of the frame and other parts of the device for which parts have been recently obtained. The main line of work to be completed is to get machined parts fabricated so that validation to begin in mid-February.

       Over the next two weeks, the team anticipates challenges related to the timely delivery of machined components and other necessary parts for testing. In the figures 1 to 9 below are the drawings of the machined components that would need to be manufactured. An additional potential issue involves the implementation of a laser sensor that will measure the displacement of the compressed polymer spring. Approval for this implementation and subsequent purchase will be sought from company representatives SLB. In figure 10, is a display of the current assembled frame that was completed during the winter break. 

    While the team waits on the SLB machinist quote, the team can only expect a lead time of 2.5 weeks to finish the remaining fabrications. Seal Team 6 plans to maintain in constant communication through email and host meetings if it's necessary to expedite or explain further details of the project. Additionally, securing an official location with the necessary equipment for prototype testing poses a challenge. In the absence of an official location, the team has identified backup options, including using a member's house, sharing a laboratory space with the AIAA DBF team in the architecture building, or using the laboratory space within Engineering Building 2.

      University of Houston Capstone Team 6 - Blog 8 During the work period of 3/23/24 to 4/13/24, Seal Team 6 made significant progress on the PSTD project. The team focused on troubleshooting the PSTD, addressing issues with the load cell, transmitter, heating band, and PID controller capabilities. Specifically:  - Adjusted the voltage on the load cell and transmitter to optimize performance. - Replace the  type K  thermocouple to resolve the inaccurate readings from the heating band temperatures.  - Re-routed wires for the PID controller and relay to stabilize the system, preventing the relay from intermittently turning on and off when the power source was to one outlet, which caused erratic output readings.  Additionally, the team enhanced the system's appearance and functionality by adding electrical wiring to connect the whole device to one main power source, creating a more integrated and cohesive system. The initial power source from the wall outlet, of 120VAC, is converted

  University of Houston Capstone Team 6 - Blog 6 From the work period of 2/4/24 to 2/17/24, Seal Team 6 is still working on completing task 4c. In task 4c, the compression parts were sent to a third party machines (Inland Machine) to be completed. The machined components will be completed on 2/21/24, pushing the schedule back by a couple of days. Besides waiting to receive the remaining machine components team 6 is unable to do much in the physical aspect of the project at this period. There has been some updates on the Gantt chart schedule with new deadlines, but it won't effect the overall project since the team gave enough buffer time in the testing phase. Team 6 is complying a list of four samples on how and why they should test the spring samples at that specific rate. The list is sent to SLB for approval. During this time team 6 will need to approximate the duration of the testing samples to coordinate and schedule a workshop location either at a member's home, SLB facili
