LED board

Daniel & Parker reviewing LED board rev 1.1

@Nolan Haines

It’s replaceable with other things (COTS) if necessary

Can bypass issues on the 1.0 version if need be - @Nathan Green

Follow up after meeting for who’s working on LED board. if not done by end of week need to start looking at COTS options

LED board

@Owen Grimm Made it blinking

touch up connections with solder if one LED is not working consistently

• next steps:

  • flashing more boards

  • EE needs to wire them up.

If boot is too large get @Nathan Green 's 200 byte code

Mech

Rangefinder mount

• TBD which side of the drone underbody this can be mounted to

• screws onto existing 30x30 pattern (60mm mounting)

  • go into one of the corners (avoid battery)

•  

Monster Mount

• Smile updating monster mount to make less wobbly → currently bad opflow data from high vibe/jitter

• To be changed just to opflow

  • When opflow need to be operational? → before CS2

  • Printed by friday

Electrical

Rangefinder Harness

• EE can make a harness that supports it at the correct length incl. CAN → UART device.

EFS

Rangefinder Config

• Make sure can->uart configured properly & rangefinder data healthy

Mech

• FPV Camera mounting needs decision?

  • Battery shrouds currently block FPV cameras

• Both (forward + downward) cameras go below the plate, same position.

  • Printed for end of this week

Electrical

VTX Wiring

• FPV feed still noisy - may be bc of groundside patch and/or abused camera

EFS

• OSD being disabled to be updated

by Wednesday!

LTE Communication

LTE good yay

Used 600 MB nice

Mech

Gemini case

exists!

Electrical

ELRS Gemini PCB

XT30 Connector pinout on the pcb is wrong (5V and Gnd pin are swapped), but still fixable with harness

e.g. with XT60 connector:

we need a harness that runs

XT60M +ve ---------- XT30F -ve

XT60M -ve ------------ XT30F +ve

superglue buck boost to correct connector side. make it hard to undo

EFS

ELRS for comp

• Basic link stats working, potentially develop better logging system? Currently using Saleae Logic Analyser

• Still need to clean up loose ends

  • test fans

  • verify transmission power

Autonomy

Pathing

conops - hover at last waypoint (end of task 2). Hover until you attempt landing.

Then wait at loiter until the pilot takes over.

Next flight test maybe test some splining…

• may need to generate waypoints between the corner waypoints for task 1

• not necessary to FT for, can do it in a simulator

Cannot do splines in task 2

Mech

Pegasus 2.0

UPDATES:

• next cabin design next finalized, layups done on Friday

• arm connectors made, need to do minor work to finish them off

• new landing gear prototype parts made, assemble later this week, hand off actual

• 7th april will assemble new cabin.

• 8-11th april will get tubes/etc cut prior to exams, for peggy 2.

• Waterproofing - @Conall Kingshott to test this next week I think

• Black latex ordered ordered for this

REMINDERS:

Before exams, peggy 2 should exist/ nearly exist. → beginning of next term is just testing! (will be handed off to EE to wire)

summer term starts May 6. We have 2-3 weeks of testing.

Improvements

• Sheet metal for Yaw Servo upgrades currently in queue for waterjet

• Once Waterjet is complete, count to machine countersinks and assemble

Electrical

custom PCB

review in progress

Arduino antenna

PCB ordered

EFS

Arduino Tracking Antenna

A lot of stuff are broken due to a circuit short

• buck converter and ldo are dead

• Neo M8Q GPS dead – we have replacement

• BMX160 the IMU dead – no any 9-axis IMU replacement, we need to purchase some

• If we plug the FTDI cable into a laptop, the laptop would passout due to overcurrent protection – but we need it for transmitting Mavlink to the tracking antenna

• I don’t think we have confirmed that arduino survive from it

• what happened in more detail: RCA - Arduino Tracking Antenna

All parts can be replaced with the new board arriving. software needs to be changed a bit

• new board has IMU built in

• LSM6DS3
