🍍 Updates this week!

Announcements/General updates

• Resume review session on Saturday, Feb 10th at 5:00PM

• LED board bring-up work session on Sunday, Feb 11th at 11:00AM

• WARG will sponsor Remotely Piloted Aircraft System (RPAS) exams, both Basic exam, Advanced exam and Ground school. Please see Internal Licensing & WARG's Flightline Progression Program (FPP) or ping Anthony Luo in discord if you are interested.

• New Projects

• Normal meeting next week

Active PCB Projects

High Current Power Module (Taim)

• Taim Al-Dabbagh

Ran PDN, messed around with it.

Generated current density diagram

Next step would be to verify 150A can flow through the board without burning up PCB

12S ESC (Mena)

• Mena Azab

• No progress. Busy week at work 😞

• need to work on

  • Field oriented control firmware setup to know MCU pinout

  • microcontroller schematic

  • gate driver schematic

6S ESC (Rayyan, Mostafa)

• Rayyan Mahmood Mostafa Hussein

• Rayyan: Power FET selection completed with power loss calculations provided

  • Jerry Tian will review

  • going through MCU, gate driver datasheets

• Mostafa: Completed block diagram, and finished initial draft for buck converter schematic.

  • Jerry Tian follow up inductor saturation current

LED Controller (Neel, Parker)

• Neel Patel Parker Lawrence-Valeriani

• Board arrived, work session this Sunday at 11:00AM

• Headers doesn’t fit too well, selecting new headers because header collide with the mount

  • right angle-ed headers to avoid collision for 1st rev

• silkscreen touchup

• no meme 💀

PDB (Tom)

• Tom Chiu

• working through redoing the block diagram to reflect recent desired architecture changes

• looking for high current output (8-12A), 55V+ max input voltage, and good thermal behaviour buck converter part

Tracking Antenna (Nolan, Hardy, Michael)

• Nolan Haines Hardy Yu Michael Botros

• going forward, routing → review → order

• done reshape-ing board

• wrapping up 2nd round routing

• ordering around 2 weeks

ZP3 Rework (Anthony, Ryan)

• Anthony Zhelnakov Ryan Scomazzon

• swapped connectors and addressed all Daniel Puratich 's routing comments

• no progress on the IMU

IMU + magnetometer is nice to have

Capacitor Analysis for Drone (Anthony)

• Anthony Zhelnakov

need to find a way to calculate inductance

CAN Interface Board (Hardy)

• Hardy Yu

Hardy will finish MCU selection before next week’s EE meeting.

Drone Harness (Neel)

• Neel Patel

Connectors don’t fit ☹️ , using a perf board for this weekends flight test

no longer powering VTX through OSD (on screen display) because wire is too thin to carry current

power solution:

get power from battery splitter → 12V buck → perf board → VTX/OSD

EngSoc Funding

Diversity Gemini ELRS , RF project Nolan Haines

needs assessment: better telemetry TX from the drone

4 antennas + 2 frequencies

• I am taking on this project

• Still in very early stages of project definition + research

Flight Test

• 2024-02-10 Pegasus + Houston Flight Test

• Jerry Tian is going, check/debug harness or we can chill and talk about your projects during the flight test.
