This week Korene and I troubleshooted our resonance issues from last week and found that the signal generators in the 220 Lab increased in voltage as the frequency increased, leading to being unable to spot the peak amplitude on the oscilloscope (the math->division menu item was also quite noisy). However, we moved to using the ADALM’s spectrum analyzer and found the resonance with no problem after setting that up.
After that, we also constructed the rectifier/receiver and transmitter circuits on breadboards and got it to output ~6V, which is the lowest charging voltage the Seeed Xiao microcontroller’s battery management system can take, but at too low of a current.
These are skills we learned in 18-220 and 18-100.
Here are some pictures and diagrams of our constructed circuits:
I also worked on the design PowerPoint slides with everyone else.
My progress is on schedule, and next week, I plan to try to increase the current delivered and try attaching the battery to microcontroller to a breadboarded circuit and get the microcontroller charging.
