DD Current Sense / Comms

✅🚹

Any update on the DD Current Sense part selection? Any update on Comms?

  • Still working on getting comms set up

  • Getting VLAN set up

  • Please update DD current sense and comms project ticket with progress updates

  • Finish VLAN setup and test

@Farris Matar

PDB/OTS BMS

✅🚹

  • Met with PDB crew to discuss Rev 4.1 changes, suggested parts for alternative load switches

    • primary and secondary switches

    • struggling on 17V

  • Could do current limiting with the STM

  • Planning to assemble SPI LVDS peripheral boards this week, will try to test them as well if possible

  • On standby for PDB reviews in future

  • Look into current limiting with the STM

  • 17V load SW

@Logan Hartford

Lead

✅

  • Met with Peter to discuss our subteams goals for the term and somethings we’d like to work on

  • Reviewed Austin’s SAR timeline and execution plan and created actionables from that

  • Assign all priority 1 tasks for the term

  • Reach out to the people on pause and see what their future commitment to the team is

  • Update project tickets

Get the bare minimum electrical systems working for the drive train to be able to move

  • What is the bare minimum electrical system?

  • What are all the all the ways we can achieve this?

  • Encoders need 5V, mostly a current ref

    • 20mA per encoder

    • 48-5V buck

  • 48V to each motor

Rayaan

Validate the OTS BMS

  • How can this be done?

  • How easy of a project is this?

  • 3/5 tough

  • Use resistors divider board to validate basic functions

    • For checking over-voltage?

  • Hook up the cells to the BMS and test basic functions

  • Someone has definitely done battery emulation before

    • google it

@Farris Matar (starting next week)

Create a SOP document for how to charge the LiPo battery pack

  • With vs without the BMS

  • What is the safest way?

  • What is the most convenient way?

  • Any concerns?

  • Should always charge it using a battery charger

  • Have the BMS hooked up as well

  • Connector solution

  • Put safety warnings, storage instructions etc

@Yuchen Lin

Complete Rev 4.1 of PDB

  • Do we have time for a work session this weekend?

  • Yes

Rishith

Validate the electrical functionality of the LED matrix

  • What exactly does this consist of?

  • What needs to be done to verify?

  • Send a digital signal to the neopixels, bitshifts

  • Just need to hit it with PWM to set the colour of the whole thing

    • arduino town

@David Choi / Rishith

/ @Farris Matar

Set up 900 Mhz and 2.4 Ghz bands

@Farris Matar / Rayaan

Dec 19, 2022

  • Performance testing complete

  • Some small schematic and footprint issues across the board

  • 17V performed well except on start up

  • 5V is very noisey

HIGH

BMS

@Joshua Harper / @Ari Wasch / Olivia

Apr 19, 2023

  • One BMS has been assembled

  • Basic non-performacne and non-firmware tests have been done

  • An off the shelf replacement is being sourced

Science

 

Apr 19, 2023

  • Need one or two people to own the assembly and testing of the science boards and work with @Ivan Lim and @Wolfgang Windholtz (Deactivated) to ensure the board is ready for competition.

  • Found two assembled boards but none of the parts if @Ivan Lim / @Wolfgang Windholtz (Deactivated) have any ideas please let me know. Otherwise we’ll just order more parts.

  • @Ivan Lim / @Wolfgang Windholtz (Deactivated) Both of the assembled boards are missing a lot of parts, do the boards have a bunch of population options?

MEDIUM

SPI LVDS

@Farris Matar

Apr 19, 2023

  • SPI LVDS Host boards should have been assembled

  • SPI LVDS Peripheral parts and boards should be in the bay now, pending assembly

  • Harnesses need to be ordered in order to wire them up together and do testing

MEDIUM

RS422

David Choi / @Farris Matar

Apr 19, 2023

  • @Farris Matar verified the design and was able to send data using the boards

  • 3 Boards have been assembled and tested
