Fever scout

Since 70% of Coronavirus cases have a fever. Mounting a thermal camera on a drone would increase efficacy.

Things used in this project

Hardware components

Pimoroni MLX90640 Thermal Camera Breakout

placeholder ir camera

NXP LPC55S69-EVK

development board. I chose this part for the cortex-m33 that is in it. I intend on using machine learning so I am concerned for processor speed. No conventional flight controler.

SoloGood FPV Brushless Motor T-Motor Air Gear 450 4PCS 2216 AIR2216 KV880 Motor 2Pair T1045 1045 Props Propeller

4 motors and propellers

GPS-PIE

IMU the development broad does have an accelerometer. But I wanted a barometer. That was a bit hard to find with all the other senors.

electronic speed controler

I was not expecting a 3 phase motor initially well so be it.

banana connector kit

The motors didn't come with connections to the ESC.

drone frame

This frame the mounting is a bit small for the development board. I am concerned I might have to drill it in one way or another.

Raspberry Pi Camera Module

place holder need a standard camera in visual

radio controller and receiver

This one is not definitive yet. I still need to check compatibility.

battery 4S

This is a place holder. I am going to check lift first with a lab power supply and current draw before selecting this. The amp hours on this one are lesser than the one in the kit so I may seek that.

SparkFun Alchitry Au FPGA Development Board

I may use an FPGA for flight mode parallel motor control. Unknown if they can output analog. If anything I will use it for camera input changing. With a multiplexer.

NXP KIT-HGDRONEK66

would be ideal less guessing and checking. It has more net cores than the development board.

NXP hgd-telem915

Telemetry Radio for HoverGames Drone

Software apps and online services

NXP MCUXpresso ide

I don't know about the px4 Libary being compatible. So I intend on making all the functions if necessary.

PX4 MAVSDK

ideally, we can use this

Hand tools and fabrication machines

Velcro

for wire management temporarily. In case of errors

22 guage wire

in case I need more wire.

Hex Driver Bit, Interchangeable

Well, this isn't what I used but the frame has hex screws that are slightly different. so get a set of hex drivers small ones.

Story

Since SARS-COV2 has a 70% chance of causing fever, a thermal camera can scout out many cases. The Drone vehicle would increase the efficiency of the taking images. When combined with computer vision.

There isn't time for the submission of code and proper testing. I don't like turning in work that isn't done yet. So for the moment, this is a parts list.
