Basically nobody has filled out the Daybreak Gantt chart. It was due a week ago
How do you expect to be able to stay on track to get this car finished by
As far as I can tell there has been literally zero progress mechanically speaking
Some of the plan for daybreak alterations are reaching beyond the scope of what we originally agreed upon
I want to have a karaoke party on to celebrate the completion of SRR. Thoughts?
Are we taking the car to F1????
Upcoming Deadlines

Dynamics
Can i please get next gen estimated weight and CG (from ground or axle or belly pan doesnt matter just let me know) of frame, aeroshell, battery? If any other system has this information on their components pls forward to me as well (idk maybe like the rest of the electronics/enclosures or smth). And if there is an estimate of CG from front or rear axle or relative to the entire car body from any of these systems it would be appreciated for this info as well. I have estimated values for all of these using things I have asked systems combined w their DB values but it would be bit more accurate from the systems to give to me. If possible can I get that tonight or like by tomorrow, even a rough guess is helpful - I can find our max lateral acceleration before tipping if I can get this information - then change track width or wheelbase to stabilize (some of the approximations of longitudinal CGs of all the mech systems are in a separate confluence article if anyone wants to see what I got) - also working on a reference sketch that will be more helpful once ^ inputs can guide the control arm lengths, sorry for the amt of time its taking - Kayla
Members are goated they listen to me and value their learning from Parra’s lectures
Communication is still a little iffy between me and the other people but giving specific pings is helping with that
Body
Good progress on brake calculations for daybreak pedalbox and revised pedal ratio for car
Test brake pedal design in progress (for daybreak and next gen)
Driver bounding box design pretty much completed
Aeroshell
New members got pretty involved, feel like everyone vibed well
Assigned research tasks to composites members
Electromechanical
Pack size/footprint finalized, might have to add a mounting extensions to modules
Panel thicknesses + ply counts finalized
Battery box skeleton model complete with new pack size
v1 of enclosure quick release mount made to fit with universal enclosure
All cooling fans selected and constraints (almost), bb intake/exhaust project set up for new members, power loss (through heat) for motor controller determined

Body
Start preliminary designs for steering wheel
Start design for ergo jig
Finalize driver bounding box/driver model

Aeroshell
Aerodynamics:
Keep building up solidworks knowledge, at least half the day spent teaching them how to do 3D parts, refining splines and relations(give them different parts to make on their own)
Give them timeline for making the shell, design constraints and everything, find something they can do that helps forward the shell design w/o solidworks, maybe aerodynamics research?
Composites:
continue research
If frame is off then start refinishing aeroshell
kevlar battery box layup
Dependent on if emech is ready for layup

IMU + RPM board Refresh - Aayush
Dynamics
General
CAD practice which gets harder and harder week by week
Readings which include them taking notes so we can create a large culmination of knowladge (working on this by also making them take notes during lectures if they can. Encouraging them to do it by increasing their knowladge along with the future knowladge.)
Suspension
changing new member projects - Daybreak centric
Daybreak Bearing Inserts - research on radial loads and bearing selection - select our new bearings
Daybreak Control Arms - CAD new ones to account for bearing inserts and groove machining (work in conjunction w ^ previous member)
Pushrod Manufacturing - they can lowkkk research some of the loads on pushrods, manufacture and helicoil new pushrod, maybe look into why we use those rod ends if they get bored
Maybe one will help steering on tie rod re-manufacturing and helicoiling
Steering
Correlate ackerman angles with physical steering geometry (4 bar probably, maybe 6 bar). Onboarding project that will be used to lead into new members designing steering geometry
Validation for components like driver visibility, seat position, pedal box location, etc.
Daybreak Steering wheel - 1 month with design reviews, prototyping and manufacturing
New gen pedal box (1 semester)
Driver model - 2 weeks design with configuration
Aeroshell
Composites:
Push rods and control arms: Aniq, Javi, and Akhilesh Composite Frame: Medha, Sai and Jaden Mold Prep: Ninette, Noya and Gaya Resin infusion: Medha and Sai
This one is is low effort so shouldn’t be an issue. also this is joint w/ conrad and one of his subleads
Aerodynamics:
nose(3 members, 1 sim, 1 research, 1 CAD, or all go)
tail(same)
canopy(same)s
Electromechanical
Cooling
Daybreak BB intake - whole semester but multiple design reviews and redesigns - Tejas
Daybreak BB Exhaust - whole semester but multiple design reviews and redesign - Annie
Battery module thermal model - Tejas
WH
Once EPLAN Software licenses come in
1. Old Battery Wiring as a starter project
3 weeks/workdays
2. Start wiring parts of the car virtually
Should be rest of the semester
Will need to update as things change
Enclosures
ABS Acetone Bath
2 Workdays
Modify current enclosures
Redo electronic placement with new boards (eg power board)
Remanufacture acrylic enclosure panels
Implementing cold plate/cooling onto universal enclosure as a starting point
Operations
✅ Action items
Mechanical Leads + subleads come up with key deadlines. Hammer out during mech leads Saturday
Leads get clickup filled out until November for daybreak with a good amount of detail
⤴ Decisions
Notes:
We need to start filling out task management tools
New software?
Gantt integration into main task management software
still use clickup
Michael and Philip make everyone's timelines?
Probably not too many things for them to do
avoid deadline snowballing
Splitting up work for daybreak between new and old members
subleads come up with detailed plans and see what can be given to new members
pair people if old member has to complete a specific task to continue learning
Check in with members 1on1
how they are doing
their timelines/progress
How to verify members know and like what they are doing
Onboarding project - introduce tools and workflows
Starter project - real project, not necessarily smth on the car but that's helps make it works too
ex can be talked abt in an interview a real project that they have worked on
