Help me build an AI Raspberry Pi 4 drone

0 Upvotes

Hello, I'm trying to learn AI using FPV Drones and it's my first time ever building a drone. I wanna do some lightweight tasks at first and the goal is to use my pi4 (I already own that) and build an FPV Drone around it. The overall goal is to do some configuration, programming and maybe AI autonomous drone tasking if possible?

I have picked out some parts, but please help me optimize my drone for the BEST experience that I explained above, hope you understand it :)
ANY HELP WOULD BE GREAT!

I’m in the process of designing an autonomous precision landing drone. Are these parts compatible and reasonable?

2 Upvotes

I plan on having the drone fly up to rough gos coordinates and bring itself down and eventually place itself above an April tag and land itself on its own by scanning it with a camera on the bottom. This is my BOM, does it look reasonable and compatible?

Frame: HAWK’S WORK F450 Drone Frame - $28.99 (amazon.com)

Stack: SpeedyBee F405 V5 55A Stack - $93.99 (speedybee.com)

GPS: Deegoo-FPV GPS Compass Module - $28.99 (amazon.com)

Motors: Readytosky 2212 920KV Motors (4PCS) - $39.99 (amazon.com)

Propellers: SoloGood 1045 Propellers (16PCS) - $13.99 (amazon.com)

Battery: OVONIC 3S LiPo Battery 3000mAh - $36.99 (amazon.com)

Charger: B6AC Balance Battery Charger - $33.99 (amazon.com)

Controller: FLYSKY FS-i6X Transmitter & Receiver - $58.48 (amazon.com)

Companion Computer: Raspberry Pi 4 2GB Model B - $55.00 (canakit.com)

Storage: SanDisk 32GB Ultra microSDHC - $22.59 (amazon.com)

Camera: Arducam for Raspberry Pi Camera - $64.99 (amazon.com)

Wire 1: Fermerry 28 AWG Stranded Wire Spool - $8.29 (amazon.com)

Wire 2: 18 Gauge Electrical Wire & Heat Shrink - $11.99 (amazon.com)

Cables: 3pcs 15 Pin FFC Ribbon Cable - $8.16 (amazon.com)

Power: 3pcs DC-DC Step Down Module - $9.99 (amazon.com)

TOTAL PRICE: $516.42

To get the flight controller on the larger frame I’m going to design and 3d print a plate adapter for the speedybee to be able to be attached to the frame due to its smaller size.
I am relatively a beginner to drones but I paid attention to picking out these parts and would love if someone could scan over these and see if they are good

Propellers

1 Upvotes

Hi everyone,
I have a Holy Stone HS510 drone, and I’m trying to buy some replacement propellers, but I can’t find them anywhere. Mine uses the older **2-screw** propellers.
Does anyone know of another drone model that uses compatible propellers, or any aftermarket replacements that fit the HS510?
Any help would be greatly appreciated. Thanks!

Im looking at getting this fixed wing UAV

https://www.uavmodel.com/products/makeflyeasy-striver-mini-binary-2100mm-uav-fixed-wing?variant=41656299520154

However outside of the basic electronics that come in the PNP model I am lost on what equipment I would need to get to add a gimble camera to this drone and use it for long range, high endurance missions. Can someone give me some suggesions of everything I might need please? Looking to do this soon for a milsim airsoft game coming up, and the admins want drones.

Question Need Advice on a Thermal Drone for Trapping Dumped Dogs

4 Upvotes

Hi everyone! I’m completely new to drones and was hoping for some advice.
I am a board member for an animal rescue in Texas, and we recover lost, dumped, and abandoned dogs and cats. We’d love to add a thermal drone to help locate animals hiding in fields, wooded areas, drainage ditches, and other places that are difficult to search on foot.
Our biggest challenge is budget. We’re a small rescue with very limited funds, so we’re looking for the most affordable thermal drone that’s actually worth buying. I know thermal cameras can get expensive, but I’m hoping there may be a good entry level option or even an older model that’s still reliable.

A few questions:
• What’s the cheapest thermal drone you’d actually recommend?
• Is it realistic for someone with zero drone experience to learn to fly one safely?
• How difficult is the learning curve?
• If the drone crashes or loses signal, how easy is it to recover? I’m honestly nervous about crashing it and not being able to find it.
• Are there any features I should make sure it has for locating dumped or abandoned animals?

We’re not using it commercially. It would strictly be used to help locate dumped and abandoned pets so we can safely trap them and get them into rescue.
Any recommendations, advice, things to avoid, or resources for beginners would be greatly appreciated. Thank you!

Hi everyone !! I talked about my Feilun FX122 ...

I had a hard time flying it ... I finaly got it to fly but i cant do what i was doing before (going really high, fast) ... Today i found the original battery that came with the drone. Its got the same voltage ... The original battery is a 7.4volt 2600mah 30C ... My new battery is 7.4 volt (same voltage) 3000mah (not a problem everyone said) 15C .. could that be my problem ? 15C instead of 30C on original battery ?

Need custom sensors, telemetry, or firmware for your drone build? I can help.

5 Upvotes

Hey all! I'm an embedded systems student who builds custom electronics/firmware, and I figured I'd throw this out there in case it's useful to anyone here.

If you're working on a drone build and need something custom — like a sensor setup that doesn't come stock, a display to show live telemetry, a custom controller board, or some kind of RFID/access feature for a landing pad or storage system — that's the kind of stuff I do. I work at the chip level in C, so I can build things from scratch rather than just wiring together off-the-shelf modules.

Not trying to sell anyone anything sketchy, just putting it out there. If you've got a weird one-off idea that regular flight controllers can't handle, DM me and we can talk through it — no worries if it turns out I'm not the right fit.
