Overview of Status of Analysis, Design, Fabrication, Tests, etc.
We will receive all 8 pieces of microwave absorbers no later than this coming Tuesday. After that, we will start to build the basic frame of the testing chamber.
Accomplishments from Previous Week
Finalized the design of the test chamber, including t-slots and door mechanism. (Han)
Managed to control the stepper motor within an acceptable temperature range. (Yue)
Preliminary tested the CPU cooler. (Yingqiao)
Determined the type of timing belt-pulley assembly (Jiahao)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Start assembling the basic frame of the testing chamber.
Yingqiao: keep looking for a way to use Arduino to control the liquid cooler
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
We have reported the contact result from 3M. They suggested that double-sided tape would be sufficient from our purpose.
We also mentioned that stainless steel foil could be another option to put on the back of the absorber. But the sponsor believed that aluminum foil would be a better choice because we would not need soldering and Al foil would bond to other things easily.
He mentioned that we could also try to find some spray adhesive.
For the CPU cooler, we could use an external laptop to control it.
For the final circuit, use perf-board, or soldering protoboard to ensure the connection of the wires.
For the issue of motor getting really hot, he suggested that one of the things we could check is that whether the motor would get hot when it is plugged in but not moving.
Aluminum honeycomb would have a performance so high that we may not need.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
(Motor turns hot after operating for a period of time) Use 10V power source instead of 12V; add a voltage regulator.
(The whole chamber is too heavy if we use aluminum plate) See whether aluminum-backed mylar or aluminum honeycomb satisfy the requirements.
Manufacture some parts to test the transmission design. Could use hand to turn the pulleys for testing.
