We will talk with every person who self nominates + anyone else who we see fit from nominations
Weef wishlist last call
WARG Jackets are here!
Pickup times (Emma Chan):
March 6, 1-6pm
March 10, 5-8pm
Workseshes
last worksesh:
Wiring for Pegasus 2 pumps
Plz come
Eclipse push soon
Pop up sessions with @Jerry Tian ?
More seshes?
Early term board order
FINALLY OUT (kinda)
Pick&Place machine
ITS HERE
@Santosh Erathasari to start looking into it?
EE Social Planning?
Game night sounds pretty epic
Snowball fight?
When?
MEGA worksesh next week
all subteams
time tbd, keep an eye out
most likely wednesday
Giving Tuesday (alumni donations towards SDC & teams)
expense claim changes
claim before march 15
security issues
theft in SDC
make sure to close & lock doors
Flight Tests
Some will be on Fridays for Evans schedule
Last flight test(s)
Feb 23: https://uwarg-docs.atlassian.net/wiki/x/AQA4t
Good progress for IR detection system
false detections
camera settings are pretty good
configs are being adjusted
Flew with Houston and successfully identified IR beacon at multiple altitudes
can be tested on the ground for a lot of this
couple hundred from last FT
some false detections are from snow reflection
vibe on Pegasus is a concern
specific mounting to help minimize
making a new mount takes time
Mar 2nd https://uwarg-docs.atlassian.net/wiki/x/AYC5sw
Peggy validation flight for W25 was successful. Flew well and same as last term
Goal was to test KML sending over MavLink on Peggy → not complete
Issues with Pi and temperature/weather that caused this test to not be successful
Tuning airframe had two flights that will allow logs to be analyzed for more adjustments
Next flight test
Mar 7th (Tomorrow)
Plan:
Task 1 Sim, KML messages over MAVLink, and foam plane pilot training
IR Beacon arrival is blocking for competition simulation, order is placed
will need EE modifications when they arrive
Reminders
Use LCSC components on new boards (Ideally from the JLC library) for PnP
TURN OFF DMMs WHEN DONE please!
Don’t forget to fill out the team roster: Microsoft Forms
Make sure to clean up after yourself
Get the electronsite role if on site - reach out to @Ryan Scomazzon if you have issues
Competition syncs Mondays at 9pm
Eclipse sync Tuesdays at 8pm
Tracking antenna meetings
Sunday 2pm
Reach out if you need help on a project or bootcamp
Recruit your friends!
More fun with friends
If you like the team, then we can do even more with more people!
BEWARE OF SCAMS ⚠️⚠️⚠️⚠️⚠️
Pegasus/Competition Updates
2025-03-03 Competition Architecture Sync - Meetings - WARG
We are happy to announce that WARG has placed second in the AEAC Phase 1 Design Paper!
Extended roster announced
form to fill
Task 1 test tom
remind what that is
tuning going well
new pump payload soon
will need ee harnessing
EFS tested LED boards. All but one work. We need to fix that and making spares would be nice.
Reflowing did not fix. Worth replacing the STM
The transceiver seems to work. RX looks good on the scope, TX doesn't.
Talk to @Derek Tang or @Ryan Scomazzon for details
Upcoming Milestone: Proof of flight video
Backup airframe task 1
Eclipse Updates
2025-03-04 Eclipse Arch Sync - Meetings - WARG
Efs tested 2nd ssd - no work
osc issue - next worksesh
still need 6s servo
@Jerry Tian updates
@Tim Gu harness updates
Project Updates
PDB @Andrew Chai @Kenny Na @Megan Lee @Santosh Erathasari
Power Distribution Board (PDB) - Unarchived - Electrical - WARG
Last meeting was the weekend before reading week started
Good knowledge transfer session + fleshing out the system
Block diagram + high level architecture finalized
Power systems design in progress
Schematic to be done in 1-2 weeks hopefully
@Megan Lee + @Santosh Erathasari working through buck converter design right now
@Kenny Na working on sensing circuitry + board level signal processing
Probably schedule meeting this week (today after meeting?? - might be too late in EST) but would be good to go over what needs to be done + check up on progress
Andrew not available Saturday + part of Sunday → will discuss in meeting
BMS @Andrew Chai @Sam Zhang @Chenxuan Yuan @Arsalan Nasrifar
Met ~2 weeks ago to discuss ideas for project + what would be good for WARG’s comp drone
Divided tasks up:
@Sam Zhang + @Arsalan Nasrifar doing custom battery pack research
@Chenxuan Yuan looking into BMS IC + board level early-stage design
Seems like a ton of really good progress made on board level IC selection, read through the confluence and it seems like should be ready to go forward with schematic design quite soon
Timeline on this?? TBD as of now
Does BMS require anything from the battery pack side of things to continue progressing?
Andrew to be less hands on in this project moving forward, should be pretty self-directed with tasks + R&D scope decently well-defined and in progress
12S Pre-Charge Controller Module@Robert Tang @Kevin Li
Higher priority things to work on
3S ESC @Kenny Na @Santosh Erathasari @Megan Lee @Magnus Scott
Board is unblocked now after midterms pog
Figured out how to do BEMF sensing
Planning to jam pack the STSPIN with optional sensing since it has many op amps built in
Can do FOC with shunt resistors, but too expensive for this ESC thoughts?
Should give it a shot if the added complexity doesn’t push design to 6 layers
Tracking Antenna Controller + ELRS Gemini Tx @Ahmed Osman@Nolan Haines
we need to solder the tx modules that game recently on the gemini tx board and test asap
once done we can get started on the architecture
@Ishman Mann can get involved
ELRS Gemini Xrossband TX @Ishman Mann
architecture defined. Schematic in progress
2 different frequencies (hence “Xrossband”)
lower frequency for better range
higher frequency for better throughput
ground-side transmitter
@Jeremy Poulin interested in schematic & component selection
12V Input to 65W USB-PD Source - Electrical - WARG @Ian Van Den Steen
Need to figure out current sense.
@Andrew Chai to help review low-side shunt configuration
Other than that need to change a couple things in schematic (change GPIO), do filter sim, then will go onto layout
12V to 24V Boost Groundside Converter - Electrical - WARG @Tim Gu
no updates, worked mostly on harness diagrams before the last meeting
Will start doing a bit more research
Sensor Cluster - Electrical - WARG @Michael Botros
Stalled until someone is able to drive it (@Megan Lee interested after getting more experience)
Open Tasks
zp4
Context: Zeropilot 4.0 Hardware (ZP4HW)
other boards
zp + interface + sensors + power = good
arch meeting
for foam plane wing
shield or board
