Here’s a Freelancer project post focused on the bird-versus-drone problem: **Title: Improve Image-Only Drone Detection to Reduce Bird False Positives on Raspberry Pi + Hailo-10H** I have an existing Raspberry Pi camera pipeline running a single-class (“Drone”) YOLO model on a Hailo-10H. Birds, especially at a distance, may be detected as drones. I need a computer-vision engineer to develop and evaluate an image-only solution that reduces these false positives without losing too many real drone detections. The camera is fixed to the drone body. The current model is available as a compiled HEF; availability of its original training weights and dataset needs to be confirmed. Development must go in a new `DetectionV2` folder. Existing Detection,...

I mainly need someone who can: - review the existing engineering package only as needed for implementation; - complete or correct schematic/PCB work where necessary; - prepare manufacturing files and BOM; - work with STM32 firmware and ADC acquisition; - handle pulsed MOSFET / inductive coil hardware; - assemble and bring up the prototype; - perform oscilloscope and LCR measurements; - debug the ele...

I’m running the latest Raspbian on a Wi-Fi-connected Raspberry Pi and I want to expose a small web project through Ngrok. I’m not even sure whether Ngrok is already on the device, so I need someone to jump in, verify the current state, install or update Ngrok as required, and then configure a secure tunnel that points to my local web server. Please run through the whole flow in the terminal—checking the existing binaries, downloading the correct ARM build if it’s missing, adding my authtoken, and creating a config file that will relaunch automatically on reboot. Once it’s working, give me the generated public URL and a quick note on how to start, stop, or change the tunnel on my own. Deliverables • Working Ngrok installation on Raspbian ...

We are building an AI-powered root-cause investigation workspace designed for industrial maintenance and reliability teams.

I need a clean, maintainable way to throttle overall memory usage directly inside the Linux kernel running on a small embedded board. My goal is to guarantee that critical processes never starve for RAM while background tasks are gently reined in before the OOM-killer steps in. The exact board can still change—at the moment I am evaluating Raspberry Pi, Arduino-style MCU boards with Linux, and BeagleBone—but whichever one we settle on, I want a single patch or loadable module that can be ported with minimal tweaks. Upstream code quality matters more than quick hacks. What I am after: a kernel-space mechanism (cgroup tweaks, custom LRU hooks, or another elegant approach you prefer) that detects when overall usage crosses a threshold I define and then slows furthe...

Scope includes real-time drone detection, object tracking, MAVLink integration, safe autonomous follow/stand-off navigation, telemetry logging, GCS interface, failsafes, SITL testing, and complete source-code handover.

...details design calculations or simulations, and justifies the novelty of the solution. 2. A working prototype or scaled model that physically demonstrates the core concept and produces measurable results I can present during my defense. Please outline your proposed idea, the development tools or simulation platforms you plan to use (e.g., MATLAB/Simulink, Proteus, LabVIEW, Altium, Arduino, Raspberry Pi, PLCs), and a rough timeline showing key milestones from design to testing. I’ll judge success on originality, clarity of documentation, and the prototype’s ability to replicate the claims in the paper....
