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)

  • https://discord.com/channels/776618956638388305/1346668846714716193

  • 2025-3-7 Pegasus 2 Task 1 Sim, KML messages over MAVLink, and foam plane pilot training - Flight Tests - WARG

  • 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: https://forms.office.com/r/ka0MJHJQ9D

• 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

• Cell Monitor - Electrical - WARG

• 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 ModuleRobert 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 OsmanNolan 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

  • Interested

    • Megan Lee

    • Ian Van Den Steen

    • Andrew Chai

    • Kenny Na

    • Ishman Mann
