I’m experiencing suspicious radio-frequency activity that appears to shadow me from place to place. To put the matter to rest—and, if warranted, take legal action—I need a qualified RF engineer to carry out a comprehensive signal analysis, identify any illicit transmitters, and compile hard evidence. Scope of work • Perform an on-site and near-site sweep that covers my home and the immediate surroundings, with attention to possible satellite-related links. • Use professional-grade spectrum analysers, SDR setups, near-field probes, and direction-finding gear to hunt for audio bugs, covert video cameras, and GPS trackers—each is a genuine concern. • Log every anomaly, capture signal characteristics (frequency, modulation, duty cycle, power level,...

A dedicated PCB will drive a self-service car-wash “vendo” unit built around an Arduino Nano. The board must accept the pulse output from a standard electronic coin slot, translate each valid coin into the required runtime, and use that signal to energise five independent relays that handle pumps, valves, or lights. All relays share a common 12 V source, yet the Nano and logic lines stay safely at 5 V, so on-board regulation (12 V → 5 V buck or linear, as you judge appropriate) is part of the layout. The relays themselves need fly-back protection, status LEDs, screw-terminal or JST headers for easy field wiring, and clear silkscreen labelling. A USB-B or tag-connect footprint for in-circuit programming is also required. Deliverables • Complete schematic (KiCad...

Project Title: Low-Power Cellular IoT Predictive Maintenance & Leak Detection System Project Overview: We are seeking an experienced developer to design and prototype an integrated, low-power, battery-operated IoT device utilizing an off-the-shelf cellular prototyping architecture (e.g., Particle Boron or Blues Wireless Notecard). The device will perform twin monitoring tasks: physical leak detection via a traditional sensor, and mechanical predictive maintenance via Acoustic Anomaly Detection (AAD). The system must run on a battery budget that supports deep sleep, waking up instantly on a leak interrupt or periodically on a timer to perform a self-test and acoustic health assessment. Data must route through a cloud middleware layer via webhooks to a custom website dashboard, with cri...

I want a small, low-noise pre-amplifier built around the NE5532, powered from + - 15v. The board will slot straight into my DIY projects, so please place the op-amp in an 8-pin DIP socket for easy swapping and surround it with proper rail filtering and local decoupling: • bulk filter capacitors on each rail (before and after any regulators you choose) • 100 nF ceramics tight to every NE5532 supply pin I need two input connection styles on the same PCB—standard RCA jacks plus snap-on terminals—so the preamp can drop into other snap-on equipped modules without adapters. Output may remain RCA only. Deliverables • Complete schematic in your preferred CAD package (KiCad, Eagle, or Altium are all fine) • Clean PCB layout and production-ready Gerbers with ...

This is a hardware development project. I require a fully functional working prototype, not a simulation, research paper, or theoretical design. The final deliverable must demonstrate ultrasonic TOF measurement on small non-ferrous metal components through a working prototype and demonstration video. I need help taking a lab-bench concept for measuring ultrasonic wave velocity and turning it into a rugged, handheld instrument that works reliably on Platinum, Silver, Nickel, and brass samples. The core tasks include designing the full analog front-end (pulser/receiver, low-noise pre-amp, gain control, anti-alias filters), selecting and driving the piezo transducers, and implementing a precise time-of-flight algorithm in an embedded platform. I am open to ARM, DSP, or FPGA solutions as ...

I need a PCB hardware designer who already understands fuel-grade gas dispenser electronics and has hands-on experience designing intrinsically safe circuits. The job centres on the control system of the dispenser; the board you create must reliably manage flow-rate control while meeting the strict electrical safety demands of hazardous-area operation. Here’s what I expect from the engagement: • Develop a full schematic that integrates the pump’s sensors, valve drivers and my chosen microcontroller, then add a custom zener-barrier stage to limit energy into the hazardous zone. • Lay out a compact, production-ready PCB (Altium Designer or KiCad are both fine) observing creepage, clearance and thermal guidelines for ATEX/IECEx intrinsic-safety compliance. • P...
