    • This MUST be considered if you want to go to competition

    • We can only bring 10 people so we definitely can’t bring everyonel/n7AK5

  • Start of term board order

    • Waiting on ELRS redundant diversity RX

    • cutoff date this friday

  • Pick&Place machine

    • discussed at leads & sdc meeting Ryan Scomazzon to fill in details from SDC meetingDiscussed at SDC meeting, not really any new info

    • If we want it we can use it.

    • Other leads are fine with us having it in the bay

    • If we still want to set it up yeah but not really useful so just if interested

Flight Test

Reminders

Pegasus/Competition Updates

  • Brief overview of competition tasks

  • Last term the plan was to land on the barrel

  • At the end of term flight test, we realized the tuning is not reliable enough for this and if the drone clips the barrel, its ggs

  • Now we will be doing a winch that lowers the pump

  • A new pump is needed, servo will likely be controlled by Pixhawk. Worst case we do an single servo driver

  • 1-2 servos needed

  • If someone wants to help with this you are welcomeWas testing a new pump, looks a lot better than the old one

  • We will need 12V on the drone.

    • Must check if PDB has enough current for 12V

    • If not we need a 48-12V buck

      • We have one that we made but it blew up.

        • Anyone wanna look into cap filtering?

      • Alternatively we can buy one off the shelf

  • Still need to do an analysis on if the pix can support another 1-2 Servos

    • Anyone interested?

Eclipse Updates

  • Jerry demoed TinyCAD for harness diagrams, we are on board

    •  Kenny Na to begin work on diagram this weekend hopefully

    • Going off of new system diagram Jerry made

    • Using the XT60 2+4 connectors

  • Need to order XT60 2+4 connectors so they get here early Feb ideally

  • 12V -> 5V @ 4A Buck Converter + ELRS Receiver board 1 & 3 not working, board 2 link drops

    • Need to order extra SX1281 RF IC & U.FL connectors to diagnose if it was an assembly issue

      • booting up without an antenna connected may have killed LNA due to high-Z power reflection

        • there was no firmware when I did this on accident, but it’s still possible…

    • Otherwise out of ideas on this one… try different antennas? 😞

    • This is just for foam plane right?

  • Redundant buck - pretty sure finished? Worth checking

Project Updates

In order of priority. These are the active design projects.

...

12S Pre-Charge Controller ModuleRobert Tang Kevin Li

  • Needs review

3S ESC Kenny Na

  • Schematic almost finished - need to tidy STM32 design

  • Would appreciate schematic review from anyone

    • MOSFET selection & RG value

  • Layout beginning soon!

  • Estimated completion EOT W25

...

  • Peggy harnessing?

  • Pegasus current limit checking

Action Items

  • Look into Pix current limits

  • Look into new projects: BMS, PDB etc…

  • Follow up un redundant rx

  • Make thread for board order and discuss chinese new yearReplacing DMM fuze/batteries?
