  • Was extremely successful

  • We were able to test a lot of things on 3 different airframes

  • harnessing on Peggy 2 worky

  • tracking antenna ee-side worky

    • not able to test with dallas, but not an ee issue

  • big dubs

  • Auto data was kinda messed up and efs couldnt get tracking antenna working

• Team photo

  • now up on the website!

• Midterm board order

  • Now Nov 7th 11th (Original date was Nov 4th) Nolan Haines

  • Current boards (speak up if we are missing you)

  • reviewed

    • Unified VTX

    • Water Controller

    • Buck w/ELRS

    • Programming Conn Adapter

• Friday Worksesh

  • RPi mounting on peggy 2 possibly Jerry Tian

• Sunday Worksesh

  • TBD

  • no more bringup tasks really

  • could do an altium sesh - let us know

• EE Knowledge Session - MOSFET Selection

  • Hosted by Farris Matar

  • November 7th @6pm (tmrw)

  • come!

• EE Social

  • escape room

  • baking

  • game night

  • tentatively set for nov 15th

• Comp/Eclipse sync

  • Eclipse sync tonight @ 8pm

  • Comp sync tmrw night @ 8pm

• Consider using JLC parts in the future?

  • Look at preferred parts

  • Basic & Preferred Electronic Components | JLCPCB Assembly Parts Library

  • Can use LCSC but costs more so try to avoid

  • Nolan Haines Kenny Na to fill this in

  • this convo explains more https://discord.com/channels/776618956638388305/1294169338508611646/1303409790789091439

  • can select to place or DNP a component

  • would need the designer to replace components with JLC compatible ones

  • will take time.

  • making a WARG account for JLC

• WEEF presentation done - went well

...

• RPi Interface Rev C - Electrical - WARG (atlassian.net)

  • Daniel Puratich Project Manager, Principle Hardware Engineer

• 12S ESC - Electrical - WARG (atlassian.net)

  • Ethan Abraham Individual Contributor

  • Knowledge transfer done with Andrew Chai

  • Placement in progress, will have done by Friday

  • 2-3 weeks from completion (estimate)

• ELRS Redundant Diversity RX - Electrical - WARG (atlassian.net)

  • Nolan Haines Individual Contributor

• Sensor Cluster - Electrical - WARG (atlassian.net)

  • Michael Botros

  • Placement finished. Stackup mostly definined. Most of signal routed. Just need to make power planes/polygons.

  • Considering impedance controlling SPI lines for >10MHz data speeds. Maybe just tune source resistor when board comes back instead of controlling line impedance → decided to just tune the resistor

  • Need to check if length matching is necessary → time difference between currently routed SPI is < 30ps, not applicable for a few 10s of MHz
