Yaw only looking good.
Will look @ 3sGoing to add some angle on yaw onlyon pitch version, going to add default is level and ability to pitch up and down.
Building the antenna starting this week.Using the tripod.No counterbalance for the yagis (fine for yaw only).HS 785 HQ, 8 rotation servogearbox is 1:7angled backplate for patch antenna (25 degrees)
Built over the weekend.
Only need to finish the backplate for backplate and laser cut lexan rotating platform to house electronics.
waterjet not working the past few days. Will be up and running sometime today or tomm.
ETA EOW
Added 3d printed parts to angle YAGI antennas (25 degrees)

component selection undergoing
Integration almost complete. BMX tested, NEOM8 not tested.
Started working on drawing the schematic of the tracking antenna pcb
Yuchen Lin Found out the prototype board he soldered wasn’t really working
We are currently making a new one with better planning, more careful soldering, and easier to use

integration code finishedhave a blocker: not finding neo m8 but solved todaywill warp up the integration testcontinue on pid motor codeWILL WRITE UNIT TESTSEvery driver finishedSensor Fusion for BMX160.
Need ground testing for decoding MAVLink GPS.

Slightly behind schedule
Electrical schematic in its last stages
missing some connector clarificationsPlanning to ask in ELRS discord
Research new component to replace PCB antennasWill require a schematic reviewPotentially other EE members or leadsAlso planning to review in ELRS discord
PCB design phase hoping to start this week
Will ideally be able to give some dimensions and sync with mechanical soon for JR module mechanical design
Antennas for ESP are mostly meant to flash firmware over wifi / OTA updatesGoing to do RS422 now, looking for Wireless in the future.if doing wireless - it can be UART.Gemini communication needs BOOT0 connection (to update over wifi).may need to use push-button // jumper
Normal communication just uses UART.
Just started PCB phase
Board will likely not be ordered before the end of the term
Will need to be tested early next term
Boot jumper, UART connection for data.

CRSF from TX16 ↔︎ TX is the same as CRSF from RX ↔︎ FC
Will use ELRS as “hop” to Gemini board.
Airport 🛫

< updates here >
Hardy looking to create wireless function for RS422, will contact Farris to get more infoHave figured out how to run their unit test today
Looking at implementing the telemetry burst in the airport first
If this work, the bandwidth of the airport can potentially double
The telemetry burst already existed in the code base but was unused because they think it need more testing and might be unstable
potentially range tests….etc.

Data Telemetry working & tested.
Mission Planner
Full flight test in simulator on Autonomy Desktop
IMACS
working on testing stuff through TCP.Once serial port working, and GUI done, need to test on drone // ardupilot.Minipix possible?
QR Code detection
Focus rn
MAVLink commands
Focus rnWorking out details on data telemetry.Working on clean architecture && making FIGMA GUI.
Have plan on what needs to be displayed.

All tasks given out, architecture created and finalized.all independent tasks completed by saturday.week after is integrationflight test on saturday post next (22nd).
GeoLocation
Needs to be refactored.Merge-odometry-and-detections module
Dronekit on Jetson
trying to keep in common repository (ground and airside). Reduces boilerplateDronekit on jetson PR just reviewed.Working on finalizing dronekit python integration into autonomy cv system.
Working on getting geolocation module support
assigned out QOL tasks to make working on the Jetson easier (during flight tests).
