Are there any projects y’all would like my help on
Areas of Interest
Array x Aeroshell layout discussion progress?
\uD83D\uDDE3 System Updates
🚨 Controls:
Updates
Motor Controller STILL isn’t working (no more CAN Issues tho)
Parthiv can say more abt this
Don’t think this is from Controls side, need to verify.
Three more members know how to use profinity/set up + debug
Maddie and Krish - Layout in progress
Lucy - Lighting schematic draft reviewed
Oscar - Leader Dash, SendTriitum
Mika - Addressing Parthiv’s ideas on dashboard, addressing pedals board accel sensor
Week Plan
meeting with Eliana Thursday to look at brakeline for board
I intend to stay on campus throughout break to catch up on whatever work is behind (after 5 PM everyday): pedals board, MC fix if possible, ordering, finalizing with dash etc.
Upcoming Deadlines
Pedal needs to have first draft completed EOW.
🔥 BPS:
Updates
Week Plan
Upcoming Deadlines
⚡ Power Generation:
Updates
MPPT ADC breakout board review
Starting MPPT fw makefiles
Array layout w/ Jason
Temp and Irradiance sense board schematic start
constant current driver re make schematic
PV capture database implementation complete; continuing database manager
training loop for model works :DD
Week Plan
finish up array layout w/ jason & send it to d2
Upcoming Deadlines
📻 Data Acquisition:
Updates
Weather + Array + Battery + Terrain all integrated. Working on simulating dynamics.
RF Receiver schematic complete. Working on layout
IMU/RPM board schematic complete. Working on layout.
Week Plan
Give thanks to the people that have given us so much
Upcoming Deadlines
- RF Board Layout
- IMU/RPM Board Layout
🔋 Power Systems:
Updates
Power board layout complete. Waiting on review. Reviews will be addresed prior to thanksgiving break and ordered by the same deadline.
Contactor driver and dataacq env board ordered.
eFuse testboard ready for review. Will be ordered alongside power board
Good progress on env board software (reading humidity and temp values on terminal).
Active precharge board undergoing a slight change (changing power delivery from LDO to buck). Finished and awaiting review.
Power monitoring board sch reviewed. Layout will start soon.
Encountered some issues when trying to spotweld on sigmaclad. Reached out to Kevin Yu (electric) with observations and questions. Havent recieved a response just yet.
Week Plan
Continue battery manufacturing (spotwelding) testing
review active precharge and eFuse testboard.
We also try out hand at the challenges placed before us. But we do it better. 😎
Upcoming Deadlines
- - Power Board Layout
- - Order Power Board
- - Order eFuse testboard
- - ESP32 Batt Char board sch
- - Power Mon board layout
- - Active Precharge layout
🔌 Electromechanical:
Updates
critical hardware back in car and harnessed
mock cooling intake done to send to regs
ready to manufacture mock modules
start characterization of a few cells with ps
Week Plan
have all battery box panel cutouts finished and dxfs created for waterjet
only layups will be a blocker then
Upcoming Deadlines
- EOD Sat - BB waterjet files
🧑🏭 Body:
Updates
Frame 1st iteration had to be redone
Jig Design plan and Welding order started
Pedal Jig used, pedal ratio was tested and confirmed for daybreak pedal box redesign
Steering Wheel layup setup tested, CFC viable for steering wheel construction, needs some refinement
Week Plan
Go over welding theory to help with jigging/welding plan
Re-finish 1st frame iteration, start ansys sims
Decide pedal box placement/bounding box
Continue work on Daybreak pedal box redesign
Upcoming Deadlines
- Nov 16, 2024 - Roll cage position/dimensions set
- Nov 16, 2024 - Driver Model finalized
🔩 Dynamics:
Updates
General:
Manufactured inserts for composites testing
Unsprung:
Decided brakes
CAD for rear a-arm structure
Suspension:
Talked with fergo to better understand bounding boxes and HDPTS need to be changed
All members got Ansys installed
Carter is doing finding the loads related to bell cranks
Oliver and La’akea began learning manufacturing with me and Gerard
Steering:
Found lower steering rack geometry
Week Plan
Unsprung:
More mockup designs for both front and rear
Break button dimensions and forces on the rotor when we lock up
Suspension:
First iteration rear reference sketch
Load conditions for suspension focusing on bell cranks
