Announcements/General updates
Resume review session on Saturday, Feb 10th at 5:00PM
LED board bring-up work session on Sunday, Feb 11th at 11:00AM
WARG will sponsor Remotely Piloted Aircraft System (RPAS) exams, both Basic exam, Advanced exam and Ground school. Please see Internal Licensing & WARG's Flightline Progression Program (FPP) or ping @Anthony Luo in discord if you are interested.
New Projects
Normal meeting next week
Active PCB Projects
High Current Power Module (Taim)
@Taim Al-Dabbagh
Ran PDN, messed around with it.
Generated current density diagram
Next step would be to verify 150A can flow through the board without burning up PCB
12S ESC (Mena)
@Mena Azab
No progress. Busy week at work
need to work on
Field oriented control firmware setup to know MCU pinout
microcontroller schematic
gate driver schematic
6S ESC (Rayyan, Mostafa)
@Rayyan Mahmood @Mostafa Hussein
Rayyan: Power FET selection completed with power loss calculations provided
@Jerry Tian will review
going through MCU, gate driver datasheets
Mostafa: Completed block diagram, and finished initial draft for buck converter schematic.
@Jerry Tian follow up inductor saturation current
LED Controller (Neel, Parker)
@Neel Patel @Parker Lawrence-Valeriani
Board arrived, work session this Sunday at 11:00AM
Headers doesn’t fit too well, selecting new headers because header collide with the mount
right angle-ed headers to avoid collision for 1st rev
silkscreen touchup
no meme
PDB (Tom)
@Tom Chiu
working through redoing the block diagram to reflect recent desired architecture changes
looking for high current output (8-12A), 55V+ max input voltage, and good thermal behaviour buck converter part
Tracking Antenna (Nolan, Hardy, Michael)
@Nolan Haines @Hardy Yu @Michael Botros
going forward, routing → review → order
done reshape-ing board
wrapping up 2nd round routing
ordering around 2 weeks
ZP3 Rework (Anthony, Ryan)
@Anthony Zhelnakov @Ryan Scomazzon
swapped connectors and addressed all @Daniel Puratich 's routing comments
no progress on the IMU
IMU + magnetometer is nice to have
Capacitor Analysis for Drone (Anthony)
@Anthony Zhelnakov
need to find a way to calculate inductance
CAN Interface Board (Hardy)
@Hardy Yu
Hardy will finish MCU selection before next week’s EE meeting.
Drone Harness (Neel)
@Neel Patel
Connectors don’t fit , using a perf board for this weekends flight test
no longer powering VTX through OSD (on screen display) because wire is too thin to carry current
power solution:
get power from battery splitter → 12V buck → perf board → VTX/OSD
EngSoc Funding
Diversity Gemini ELRS , RF project @Nolan Haines
needs assessment: better telemetry TX from the drone
4 antennas + 2 frequencies
I am taking on this project
Still in very early stages of project definition + research
Flight Test
@Jerry Tian is going, check/debug harness or we can chill and talk about your projects during the flight test.
