General Updates
NO MEETINGS for reading week and midterms
This is our LAST meeting before reading week
Next one TBD with date below
New faculty advisor: Brandon DeHart
All roads lead to Teerstra
No more faculty advisors
Brandon DeHart Manager of the RoboHub
Last flight test
Did not go well
Changed some configurations which did not work when we got there
Could have been avoided by testing in advance
We are working on/discussing how to prevent this from happening
Encouraged to read debrief: 2024-10-05 Pegasus 2 & Houston - Flight Tests - WARG (atlassian.net)
Next flight test
Retrying last week
Testing geolocation
Maybe Rpi killswitch?

Hotplate here! - in our possession!
CSA approval only for AC devices
works good, used for reworking boards in tdy’s sesh
Heat gun fixed!
Midterm board order coming up @Nolan Haines .
I (Nolan) will being going around and asking people with ongoing boards what their status is and for a timeline for when they’ll be ready to order the board
Please ping @Nolan Haines in your channel if you have a board that you think should be on this order
We are currently aiming for Nov 1 but this is tentative - this might changed based on the feedback you guys give me about your timelines
Confirmation this week
Might be worth pushing it a week? - no more than that
@Jerry Tian is gonna do a presentation on validation on oct 28
topics:
theory behind tests, e.g. load/line regulation, load transient, buck vout ripple
instrumentation, e.g. eload internal circuit, eload v.s. source measurement unit (SMU)
Missing GPS
Airplane cleaning using Dallas
Dallas new name instead of Houston.

Planning on onboarding his replacement early
Please fill out this form if interested:
Form will be open until October 28 @ 11:59PM
Board bring up Status
Please update test plans/board documentation!
Discovered issue with buck on multiple board
Vin tied too high
Vdd needs external ldo supply
Tried to rework tracking antenna - didn't work today
Looking for other mistakes causing issues
Plan Going forward:
Looking into better board review process
should implement formal review process - be more thorough and meticulous in review process
checklist - we have one but have not been using it lately
have multiple people reviewing and splitting up work for different components
have other ppl review design, not just main engineer
Be careful about taking designs from other boards that have not been brought up and validated yet
Board Name | status | blockers | plan going forward |
---|---|---|---|
Tracking antenna |
|
| continue debugging and document process |
LED Lighting REV3 |
| Board A has issues, to be resolved in worksesh not tested with EFS yet  all functional but one from efs testing |  |
6S Servo Module |
| Â | Â |
GPS Breakout |
| can’t find GPS board that needs to be soldered on, ask autonomy? | |
Single Servo Driver |
| Finished other side today during work session. Did not get to validate or fix up neopixels. Will likely be done post-midterm |
Peggy 2/Comp Updates
@Jerry Tian For Peggy 2
no tasks on peggy 2 this week
analog system unvalidated
lighting boards coming up
harness schematic in the backlog
tracking antenna not working
Documenting battery harness can be done still - lower priority
LEDS boards should be installed as soon as validated
Eclipse Updates - Fixed Wing 2025 - SysInt - WARG (atlassian.net)
New program name!
The below boards should be included
6S servo module
making new rev to be ordered with midterm board order
Single Servo Driver
should be good, needs: rework and validation
6S power module
highest risk
lowest necessity (RIP lol - Andrew) :(
Come to meeting tonight
Bootcamp Updates
Continue to pop off and ask questions in your bootcamp thread
