Signal Processing Jobs

Please note this is not just a PCB design task, I need a complete implemented solution I need a compact, ultra-low-power PCB that can read a group of simple slot-mounted switch and immediately report its state over Bluetooth. The board must operate from both a rechargeable battery and a small solar panel, so smart power-path control and energy harvesting are central to the design. I picture a single microcontroller with integrated Bluetooth Low Energy, a high-efficiency buck/boost stage, battery charging and protection circuitry, and a clean, debounced input line for the switch. Low standby current is critical: the device should sleep until the switch changes or a scheduled health-check broadcast is required. Once the object is placed or removed, the board wakes, advertises the new st...

PCB Designer Needed – Ultra-Compact Automotive/Motorcycle BLE Control Board I'm seeking an experienced PCB designer to develop an ultra-compact, production-ready control board for a 12V motorcycle accessory. This product will be installed in a sealed enclosure and operate in a harsh automotive environment exposed to vibration, voltage transients, temperature changes, and electrical noise. The primary design objective is the smallest practical PCB while maintaining reliability, low power consumption, and manufacturability. Functional Requirements The PCB must provide: ESP32-S3 with BLE connectivity 3-axis motion sensing for deceleration detection 12V automotive power input with appropriate protection Reverse polarity protection Transient voltage suppression (TVS) High-side ...

I need a machine-learning expert who can take raw time-series signals and turn them into accurate, production-ready models. The entire effort revolves around signal processing—filtering, denoising, feature extraction—and then building, training, and validating models that make reliable predictions from those signals. The data you will handle arrives as multichannel time-series streams. You will decide on the best preprocessing pipeline (e.g., wavelet or FFT filtering, adaptive smoothing, normalization), engineer features, and then implement and compare models such as CNNs, transformers, or traditional algorithms if they outperform deep nets for this context. Python is my preferred stack; NumPy, SciPy, scikit-learn, PyTorch or TensorFlow should feel second nature to you. Robust...

The PCB should control the following functions: - Lighting - Flush system - Ventilation - LED lights for error indication Ideal skills and experience: - PCB design expertise - Experience with control systems for lighting and flush mechanisms - Knowledge of integrating LED error indicators - Background in designing compact and reliable circuits for confined spaces and has to fill up this and help me place to order

I need a custom RISC-V integrated circuit designed specifically for embedded systems with essential inbuilt security features. Key Requirements: - Designed for embedded systems use - Essential inbuilt security functionalities Ideal Skills and Experience: - Expertise in RISC-V architecture - Experience in IC design for embedded systems - Knowledge of security protocols and implementation in hardware - Familiarity with low power consumption and real-time processing is a plus

I already have a complete schematic for a multi-function meter built around the STM32H743BIT6. Before I move to PCB layout I need a fresh set of eyes to refine the design, swap a few key parts, and fold in two new capabilities. Work required • Correct any schematic errors you spot (net ties, pin assignments, power flags, ERC issues). • Replace the specified parts—new values for several resistors and capacitors plus an updated pin-compatible MCU revision. • Add extra sensing channels and tighten the power-management section so the board runs cooler and meets my standby-current target. • Schematic circuit diagram design and PCB Design in Altium software. We may provide Altium software. • Simulation required in Proteus software. We may provide software. &...

I need a schematic completed in EasyEDA for a small PCB that will trigger three illuminated or non illuminated switches. Each switch is to plug in to a JST plug. The board turns three analog inputs into a plug-and-play USB joystick (X, Y, Z) that every modern Windows, macOS or Linux PC will recognise instantly. In addition I require 2x3 male header pins that will allow 3 LED's to light up when the switch is turned on. Connection to PC The PCB is to have a standard mini USB type B connector for connection to PC or Mac. No drivers are required. Plug it in and use straight away. Powered by USB bus (+5V - 500mA) so no external power supply would be required Full-speed 12Mb USB connection. Unique serial number that helps Windows remember each device - Controller retains settings even i...

I’m building a small module that sits on a vehicle’s CAN bus, intercepts the speed signal reported in kilometres per hour, and outputs an equivalent message in miles per hour. To complete it I need an automotive electrical-systems specialist who can take the idea from schematic through to verified firmware. Here is what I’m expecting: • Hardware design – a compact, robust converter that can be wired in line with the existing CAN bus loom, powered from the vehicle supply, and tolerant of automotive noise and temperature ranges. • Software programming – firmware that listens for the specific speed PID, converts the value from km/h to mph with the correct resolution, and re-injects the new frame on the bus without disturbing other traffic. I&rsqu...

I'm seeking an experienced digital circuit designer to create an alarm system for a bilge pumping system on a boat. It’s a one off project is for my existing business. When the 24 volt 15 amp bilge pump activates, from a float switch, a light and buzzer must sound. When the pump has deactivated because the float switch has deactivated, bilge empty, the light and buzzer must stay on until a reset button is manually pressed. If the float switch reactivates the light and buzzer must stay on until reset is pressed. The alarm is to warn the boats skipper the boat has a problem which needs solving. Key Requirements: - Design a digital circuit specifically for a marine alarm system. - Ensure stability and reliability in various operating conditions. Wet , violent movement, noisy. ...

I have two BLDC motors running on VESC-based controllers and I need them responding smoothly to a radio-frequency hand-held remote. The goal is true “tank style” drive: forward, reverse, pivot left or right, plus proportional speed and braking on each trigger. Here is what I still need done: • Bind and map the RF receiver to both VESCs so every channel on the remote translates cleanly to speed, braking and direction. • Set safe current limits, regenerative and active braking parameters, and be sure neither motor over-currents under stall conditions. • Calibrate RPM and refine torque curves so the response is even across the whole throttle range. • Synchronise the two controllers over CAN so they act like one power-train without cogging or desync a...

I’m ready to take a proven mean-reversion idea and turn it into a fully automated Pine Script that runs natively inside TradingView and fires live orders to my forex broker via alerts. The core logic is already outlined—I simply need an experienced Pine developer to translate it into clean, well-commented code, optimise it for multiple currency pairs, and make sure it can be toggled between live trading and back-testing without any manual edits. Key goals • Generate precise long/short signals the moment price deviates from a configurable moving-average band and reverts to the mean. • Include risk controls: adjustable stop-loss, take-profit (fixed pips or ATR-based), and a maximum open-positions cap. • Build easy-to-read inputs for position sizing, session ...

Am nevoie de un design complet pentru un modul WiFi capabil să trimită date UDP pe o distanță de aproximativ 500 m în câmp deschis, în special deasupra apei. Nu vreau să folosesc repeater; soluția trebuie să își atingă raza doar prin hardware-ul propriu și o antenă sau booster potrivit(ă). Accept atât ESP32, cât și ESP32-C3; aleg componenta optimă în funcție de propunerea tehnică. Este esențial ca datele să poată fi recepționate de o aplicație mobilă pe Android și iOS. Te rog să-ți concentrezi răspunsul pe proiectele anterioare similare, astfel încât să înțeleg rapid experiența ta în: • implementarea conexiunilor WiFi pe distanțe mari • optimizarea puterii de emisie prin amplificatoare/antene • trimitere...
