After the flight test summarize the timeline of what happened. With timestamps if timestamps aren't given in checklist?

Tubie Flight Test

• 10:15 got tubie fully setup and attempted to flight Tubie

• @Aidan pilot, @Hardy threw the plane. we failed taking off the plane two times in a row. Both attempts, the plane lost power right after it is been thrown.

Raspberry Pi Powered w/ 12V

What happened:

• The autonomy houston flight test is scheduled on Oct 21st. The autonomy team got the software ready and installed in the Pi, mech ppl help mounting the camera and pi onto the drone, but the power to the Pi wasn’t done before Oct 21st

• 8:30am Oct 21st, Hardy Yu Amy Hu who come to the flight test decided to solider the power for the Raspberry Pi themselves in a rush to meet the flight test timeline. Hardy Yu proposed the plan of splitting out the power from the xt60 output of the Holybro PM02D to power the PDB and Pi at the same time. The splited xt60 connect to a usb c breakout board and then power up the Pi. Daniel Puratich also help on the solidering process and very roughly reviewed the plan. we powered the Pi without it ever been tested with multimeter and power generator. However, later on we found out the xt60 output from PM02D is the battery voltage and that fried the Pi.

What we should do to avoid similiar triggic from happening in the future:

• Any newly created electronics should be tested before used

• If flight tests prerequisite aren’t meet, we should really consider delay or cancel the flight test

• and more …. add to this
