Work sessions

Gonna have to start splitting harnessing and PCB bring up
More people would be hype as we start doing more
Adding an additional work session in the week for harnessing?
Leadership can split who runs them if it is too much for one person?
@Kenny Na maybe can do a lettucemeet
Early term board order
@Kenny Na
Sarah has been away from office

@Sam Zhang ?
Discuss here Discord - Group Chat That’s All Fun & Games
EE Social Planning?
Game night sounds pretty epic
Snowball fight?
Flight Tests
Last flight test
February 8th
Plan: Cluster estimation
Comp roster people should be at these now
cancelled due to insufficient ground testing, moved to next flight test
Next flight test
Feb 15th
Plan:
test autonomy system
detect target for IR beacons
run autotune for tuning airframe
Solid chance it gets cancelled due to snow
Reminders
Use LCSC components on new boards (Ideally from the JLC library)

Pegasus/Competition Updates
EFS tested LED boards. All but one work. We need to fix that and making spares would be nice.
Reflowing did not fix. Worth replacing the STM
The transceiver seems to work. RX looks good on the scope, TX doesn't.
Talk to @Derek Tang or @Ryan Scomazzon for details
Eclipse Updates
Found an SSD (it works)
We need another, we have some that aren't validated.
Spares are nice too
6S servo updates
@Tim Gu hopefully on track to getting harnessing done by Feb 15th
Still on track
Needs to figure out wire gauges
Doesn't know how much current ssd and 6s servo uses
6S servo 4A max
1A SSD
Eclipse Power & Can Splitter Harness
Going for a top-down approach for a harness schematic, high-level block diagram is done
TinyCad drawing is in progress @Tim Gu
