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
Array and battery sim are hard
Leaderboard progress continues
Week Plan
We try our hand at the challenges placed before us
Upcoming Deadlines
- RF Receiver Schematic
- IMU/RPM board proposal
🔋 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 (hardpoints changing caused this, that problem is solved now)
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 → needs to be refined?
Week Plan
Frame
start simulating frame → get initial data for first iteration
create initial design ideas for frame jig
Ergo
continue working on steering wheel designs
finish up daybreak pedal box changes (test pedal jig, finish design)
start work on next gen seat
Upcoming Deadlines
- Nov 16, 2024 - Roll cage position/dimensions set
- Nov 16, 2024 - Driver Model finalized
🔩 Dynamics:
Updates
Unsprung: Unsprung ran sims on axle diameters, tried out SKF Sim Quick Pro for bearing and trailing arm geometry began development
Suspension: Suspension researched adams kinematics software, Kayla worked on refining her sketch to find non-hdpts defined values, trailing arm geometry began development
Steering: Steering worked on bump steer research + created a 3D sketch for Ackermann because I had anti for some reason + found the C factor of the old steering rack on the car + found issues with steering placement relative to the bounding box that we have + found a steering geometry that should work for new gen
Week Plan
Unsprung: 2 upright designs, 2 hub designs for Sami, Sumi, and Sohan. Jonathan works on rear swingarm which shows methods of motor and caliper mounting
Steering: Research bump steer optimization and have it implemented in CAD by workday
Suspension: Carter secures adams/dynatune, La’akea sims pushrods, Oliver sims control arms, Manas works with Jonathan on refining trailing arm hdpts
Upcoming Deadlines
- - Location of steering rack (code is broken, talking to Jacob about it. Will try to get a value that is worst case though.) - Steering
