Active PCB Projects
High Current Power Module (Taim, Steven)
...
Got PCB layout reviewed, will address shortly before starting routing
12S ESC (Ethan, Chris)
Ethan in India
6S ESC (Rayyan, Mostafa)
Mostafa: Attended buck control session by Farris, and decided on using electrolytic capacitor for output cap, started reading into current sense.
Rayyan: Have Power MOSFETs selection down to a couple MOSFETs. Will have selection finalized by next meeting along with majority of everything else related to gate driver circuit.
I also attended Farris' Control Loop Learning Session and learned a lot and feel big brain now.
Both of have our Asana goals updated.
Rayyan: Component selection for gate driver circuit done by Nov 30th. MCU circuit by winter break. By end of winter break to have schematics.
Mostafa: Buck and current sense component selection done by Nov 30ths. Schematics done by end of winter break.
LED Controller (Neel, Parker)
Setup another meeting to go over component selection.
Meet before next Sync (Saturday)
Neel will be gone start of Decemeber December. Plan to have at least component selection and parts ordered. Leaving assembly and testing.
ELRS Gemini (Michael, Farris)
Boards cleaned up & ready for use now
Project is now in EFS hands, Farris still on campus for rest of semester & can provide support
Good work Farris and Michael!
Jerry Tian will take a look after the flight test.
Drone Battery PCB (Farris)
Still need to take some measurements & draft a rough outline to determine price & power capabilities, will probably be some delay on this though as I’m bogged down by schoolwork
PDB (Tom)
Continuing with trying to figure out a method to maximize the use of ADC resolution with variable voltage input.
Last midterm finished yesterday, will have more time to get back on top of it.
Would like to finish before end of term.
Finish schematic design in next two weeks.
Troubling thinking through values for components in voltage divider/zener diode/hp filter before signals enter ADC for current and votlage sensing.
Look to finish working through this issue before Monday next week
Figured out which components are required, now need to determine component values.
Tracking Antenna (Nolan, Hardy, Michael)
25-5V buck schematic done
Schematic still throws some errors but I think they're easy to fix
After review onto layout I suppose?
Michael will continue to work on power analysis.
Will redo some of the connecters and portsNolan Haines Hardy Yu Michael Botros Please update.
Schematic is close to being finished for voltage sensing. Measuring the differential voltage between all 6 cells. Low battery indicator and automatic shutoff.
Overcurrent protection, SD Card, Shield connectors remaining.
SD Card and shield connectors Hardy Yu
Overcurrent protection unassigned. Nolan Haines
Goal to have board done before exam season.
12S Servo Module (Jerry)
Jerry: pushed deadline by 1 week to Nov 23rd since I'm not confident with PCB trace routing.
Will talk to Daniel.
ZP3 Rework (Anthony)
