    • WE ACTUALLY KILLED IT THIS TERM NICE JOB EVERYONE

    • Ryan Scomazzon To talk a bit looking back on how epic we did

  • Last flight test

  • Next Flight Test - Nov30th

  • Final Flight Test of the term - Dec 14th

    • Testing both solutions for task 2 - pump (water controller) and scoop (single servo driver

    • water controller is pending on EE - we need this assembled and validated by then!

    • PULL UP!!

  • Winter 2025 EE Co-op

    • An EE coop would be really epic but we need a mentor to have one!

    • If you wanna be a coop mentor, please reach out to EE leads. It would be really really epic and cool and awesome sauce.

    • EE co-ops have been actually popping off (nice job guys)

    • DEADLINE IS TOMORROW so please reach out now if interested!!!!!!!

      • We would still have to make the job description and get it reviewed so must let us know TN

  • PMs next term

    • We are looking for PMs for next term

    • Going to release a form after finals, please keep an eye out if interested

    • No questions on the form, just submit if interested

    • We will talk individually to everyone who fills it out to see PM role would work and go over expectations.

    • Can be on OR off site.

    • Please fill out even if already PM so we can see if you wanna be PM next term

  • Midterm board order

  • EE Work session

    • No more work sessions this term

    • Today’s

      • successful bringup of water controller!

        • 3 Boards Assembled

      • validated + powered up, should be good to test w/ mech system pre-comp sync

      • Pre-charge system working

    • Friday’s

      • potentially bringup more boards

      • check availability of members (finals)

      • if no one avail, cancel this sesh

      • likely no sunday sesh either unless people would be interested in more board bringup

        • Likely not

  • AEAC Town Hall #1 happened

  • PCBX Sponsorship Ryan Scomazzon

    • Good news and bad news

    • Good news: Turns out they didn't ghost us, it just got sent to junk

    • Bad news: They are ops of deception and basically used this as a marketing campaign. Their offer for free services was only for the first order and everyone gets this as a new account promotion. They conveniently didn't mention this in their first email.

    • They mentioned something about offering a discount to us for long term cooperation? I sent an email to push for what we can get out of them but I think this is probably a dud

    • Back to looking for a JLC sponsorship, I can use some help with that.

  • Comp/Eclipse sync

    • No eclipse sync

    • Comp sync tmrw night (Thursday) @ 8pm in E5-2103

      • LAST COMP SYNC OF THE TERM

  • Beginning of term order

    • Who wants to be on it?

    • Reasonable timeline?

  • TOASTER OVEN ACQUIRED 🔥🔥🔥🔥🔥💪 💪 💪 💪 💪

    • Plz dont store things on top of it or touch the top - it gets hot

    • Dont put food in there because we will be using leaded solder in there which will make your food not something you wanna eat (unless you want cancer)

12V to 24V Boost Groundside Converter - Electrical - WARG

  • Tim Gu

  • Asked about some requirements/constraints for this board, hoping to start doing some of the math once I

  • Looking into options for buying one premade

  • Read over some guidelines from Texas Instruments on working with boost convertorsDid some research on designing/working with boost convertors

  • Getting started on calculations

    • Input current may be around 90-100A (very rough estimate)

    • How much current is too much (to the point where we can’t make this ourselves)?

  • Looking into COTS options for buying one

    • There are some 12-24V 50A DC/DC convertors that seem promising at first glance, will dig deeper and document updates

  • some ideas:

    • If we don’t charge 4 batteries at once the input current will probably be a lot lower

    • maybe use multiple boost convertors (like a multiphase buck)?

Water System Controller rev 2 - Electrical - WARG

...

Shawn Yang add link for new doc and any progress

...

  • Working on schem still

  • After this weekend will be on hold till after finals

  • Target for start of term board order

Action Items

  • Make source of truth for board priority and add more single servos to it

  • Check up on elrs status

GOOD LUCK ON EXAMS 🙏🙏🙏
