General Updates
Last flight test
Outcomes
got a lot of geolocation and flight logs
got a lot of images from the drone
not great quality
Next Flight Test - Nov 23rd
Goals
Test tracking antenna pitch & yaw with houston
Test autonomy systems
cluster estimation
image collection
Pilot training for peggy 2
Pilot training moved to 30th flight test
Final Flight Test of the term - Dec 14th
water controller
we need this assembled and validated by then!
PULL UP!!
NEW PCB SPONSOR ?????
PCBX
Covering PCB & PCBA
Ryan looking into logistics
reached out to warg for free PCBs and PCBAs (WARG is big time)
Tryna see what they are willing to cover
Midterm board order
Please follow post ordering backup processAltium Folder Structure & EE Project Backups | Post Ordering
Please prepare a Digikey list with all components needed still and put in Midterm PCB order channel Discord - Group Chat That’s All Fun & Games
boards that still need them
Sensor Cluster
LED controller rev 4
Please follow this guide to complete your orderDigikey Orders
Make thread in #ops-purchase-request so there is a thread to chat about it
If you need stuff from Digikey, now is the time to speak up so we can throw it on this order
EE Work session
