I need the full design of a six-layer Primus X2 flight-controller board reconstructed so I can port its VFX interface to an STM32 platform. My end goal is to feed a live video stream through an ESP32-CAM, so the reverse-engineered design has to include the exact pathways, pin mapping and signal integrity considerations that will let the STM32 pull that stream in real time. I already have the physical board; what I do not have are the original CAD files, annotated schematic or stack-up. Where the footage ultimately lands is not important right now—just make sure the design can sustain continuous live video. Deliverables • Complete schematic capture, showing every net, component annotation and test point • Layer-by-layer PCB Gerber or native files (Altium, KiCad or ...
Hardware Development - Microcontrollers Integration with Software Iot AI ML
I am looking for a skilled electronics technician or hobbyist experienced with component modification to upgrade a "Retro style" style video guest book (pictured). The goal is to improve the recording quality by replacing the existing internal camera and microphone with higher-fidelity components. The Task Includes: • Component Sourcing/Advice: Recommending a high-quality, wide-angle camera module (e.g., 1080p or 4K USB/MIPI module) and a discrete, high-gain microphone that will fit within the existing housing. • Disassembly & Installation: Carefully opening the unit and swapping the original hardware for the new modules. • Integration: Ensuring the new components interface correctly with the internal software/storage system. • Testing: Verifying clear aud...
I need a compact-footprint PCB that runs on a solid 12 V input and plugs straight into Ethernet so it can sit inside my equipment rack and let the rest of my system know everything is still alive. The board’s sole job is to send a small heartbeat packet at set intervals and, if the link ever drops, push an immediate network-status alert that my database can log. Remote-monitoring bells and whistles are not required right now; reliable data transmission and clear link reporting are the priorities. You can choose the silicon you are most comfortable with—an MCU with an integrated MAC/PHY, an external PHY hanging off an ESP32, or another combination—so long as it boots quickly, keeps the BOM lean, and exposes a straightforward way for me to adjust the heartbeat interval lat...
We are building SmartPTI™ Pro — a patent-pending, AI-powered commercial vehicle safety monitoring and predictive maintenance device developed under the TruckerGuard AI™ brand. It is designed for Class 7 and Class 8 commercial trucks operating under FMCSA regulations. SmartPTI™ Pro is not just a pre-trip inspection tool. It is a data-driven AI system that learns each vehicle's patterns over time and predicts mechanical failures, tire degradation, brake wear, and electrical faults before they happen on the road. This transforms it from a one-time checker into a continuous safety intelligence platform for fleets and owner-operators. This is a patent-protected, funded product with direct fleet industry backing from someone working inside commercial vehicle sa...
I need a single 2-layer PCB designed, fabricated, and assembled for a compact ultrasonic microphone jammer demo unit. The device emits a frequency-modulated 24–26 kHz ultrasonic signal that disrupts MEMS microphone recording on nearby phones. This is a privacy/anti-eavesdropping demo unit. The circuit design, schematic, netlist, and firmware are ready — I need PCB layout, fabrication, and assembly. What I Have (Will Be Provided) Complete circuit schematic (PDF, A3) Netlist with all connections and component references Bill of Materials with exact part numbers and footprints Firmware source code (Arduino .ino for ESP32-C3 Super Mini) Reference design from open-source project (mcore1976/antispy-jammer on GitHub) Circuit Summary Signal chain: ESP32-C3 Super Mini → AD9833 DDS ...
Hi I will share the details with the shortlisted candidates. thanks
I’m building FoodEase, an automatic cooking appliance that runs on a dual-core ESP32. The project is already architected around native ESP-IDF and FreeRTOS, so I need someone who can jump straight into low-level work—no Arduino abstractions—while still writing clean, production-ready code. Here’s what the firmware must do today: handle precise motor control and thermal regulation, collect and analyse data from temperature sensors, and maintain rock-solid Wi-Fi/BLE connectivity with a fully recoverable OTA update path. All of this has to coexist smoothly under FreeRTOS, so tight task scheduling, queues, semaphores and event groups are second nature to you. You’ll be driving PWM channels for the motor, talking to temperature probes over I²C, and keeping...

Key Requirements: - Integration with temperature, pressure, and proximity sensors - Robust data handling and processing - User-friendly interface for monitoring and control Ideal Skills: - Expertise in Python and industrial automation - Experience with sensor integration and data management - Strong problem-solving skills and attention to detail Please provide examples of similar work done.
I’ve thought of a product that springs to life at the tap of a phone or web button, and I need a talented maker to turn that idea into a fully functioning prototype. The core is a pop-up mechanism—whether you favor solenoids, springs, or a tiny geared motor, I’m open—as long as it rises smoothly, reliably, and safely. Control will come from a Raspberry Pi or Arduino (again, whichever you feel best suits the task), with clean wiring and firmware that listens for a remote trigger. Alongside the hardware, I’ll need a very lightweight app or web page that exposes a simple trigger; bonus points if you can add basic status feedback without over-engineering. I’m happy to supply sketches and dimensions. To keep the conversation focused, please share: • P...
We are looking for somebody that can help program a raspberry pi for charging solutions for electronic scooters. This project needs to allow 2 to 3 user accounts to control the kiosk and upload ads to the station. Im a solo running business and I dont have a lot of funds for this project so I am looking for a freelancer that can help for a good price. Not cheap, but affordable I want to make sure you will be compensated for the good work youll provide. Some more info about the project: We need the station to accept tap payments through Square card reader and they will accept card and phone payments. We need help designing the UI so it’s smooth and have a sleek design. Station needs a good transaction system where a person chooses on the interface how much time they want to c...
My current firmware for the PIC18F46K22 already drives a 128 × 64 graphical LCD and a 4 × 5 keypad without issues, yet I now need to extend its functionality: two additional real-time parameters must be calculated and shown on designated areas of the screen. The existing project is written in C, built under MPLAB X with the XC8 compiler. Your task is to: • add the new variables to the main control loop, • update or create the drawing routine so these values appear neatly in the reserved zones of the display (font, coordinates and visibility must match the style of the current UI), • adjust any supporting timers, buffers or ISR code so that refresh rates and memory usage remain within device limits, and • return clean, well-commented source files th...
I need a Tuya IoT template tailored to an indoor, smart clothes-drying rack. The goal is to define all DP points, panel layout, and interaction logic so the finished product integrates smoothly with the Tuya Smart app and cloud. Key functions I want covered include basic lift/lower controls, timed drying presets, temperature / humidity display if the hardware supports it, and in-app notifications when a cycle completes. Please map the data points clearly, assign suitable icons, set default units, and ensure the UI looks polished on both Android and iOS. I will provide the product schematic and MCU protocol once we begin; you return the completed template file (plus any panel resources) ready to import into the Tuya developer console. A quick screen-share walkthrough of the finished s...
I have Virtual DJ and Djay Pro running smoothly—my mic is live, the main sound is reaching the audience—but I still can’t preview tracks in my Bluetooth headphones before they hit the master output. Because I’m working strictly inside the software with no external controller or mixer, I need someone who knows the internal routing menus, aggregate devices, and audio settings inside both programs to jump in and set this up right away. The goal is simple: cue audio must play exclusively in the headphones while the master keeps streaming as it does now. A short remote session (Zoom, AnyDesk, or similar) that walks me through the exact settings, channel assignments, and any necessary aggregate-device tweaks will be perfect. Acceptance criteria: • Bluetooth h...
I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...
