Signal Processing Jobs

I already have the full schematic and the finished PCB files for a board that combines an ESP module with a PIC18F microcontroller. What I’m missing is a clear, practical explanation of how everything talks to each other, especially over UART, and how that interaction is implemented on the physical board. Here is what I need from you: • A step-by-step walkthrough of the signal paths that handle UART traffic between the ESP and the PIC18F, including any level-shifting, buffering, or hand-shake lines that support the link. • A guided tour of the PCB layout that shows where those signals travel—layer changes, vias, ground references, decoupling, and any routing choices that affect integrity or noise. • Simple notes on any supporting circuitry (power rails, ...

I need a focused research effort that looks at satellite-communication antennas from three angles at once: maximising signal strength and quality, mapping frequency-band usage, and refining antenna design and materials. The outcome should give me clear, data-backed guidance I can hand straight to my hardware team. Scope You will survey current literature and patents, run electromagnetic simulations (HFSS, CST, FEKO or similar), and translate the findings into practical design recommendations. Emphasis is on L-, S- or Ku-band performance; however, if your analysis uncovers a better-suited band, flag it and justify the choice. Deliverables • Concise comparative report (PDF) • Simulation files with setup notes • Performance charts showing gain, VSWR, efficiency and li...

I am putting together a self-funded, individual project that calls for a fully specified gas-chromatography system fitted with both a Thermal Conductivity Detector (TCD) and a Flame Ionization Detector (FID). The goal is to separate and quantify light hydrocarbons—specifically methane, ethane, ethylene, acetylene and closely related species—in liquid samples that will be injected directly or via headspace. What I need from you: • An end-to-end design covering column selection, carrier gas choice, oven programming and detector configuration so that both TCD and FID work in tandem without signal overlap. • A step-by-step method for sample preparation and injection that delivers sharp peaks and reliable quantitation for the compounds listed above. • Calib...

I’m running an InHand IG502 cellular gateway and need a focused Python add-on that exposes the unit’s current RSSI (raw dBm) as a holding register inside the built-in Modbus server. The immediate aim is simply to monitor signal quality; once the value is available we will pass it through our existing RS-485 link into the DNP3 layer of the external SCADA. Key points you should know while coding: • Device: InHand IG502 (OpenWrt-based, Python 3 available). • Output format: raw signal strength value, no scaling or percentage. • Register must be readable via Modbus-TCP and Modbus-RTU so I can map it downstream. Byte order can be little-endian; just document what you use. • Communication onward to DNP3 happens on my side, so the script only has to populate ...

I’m developing a compact medical-grade board that will sit at the heart of a new vital-signs monitor. The PCB must reliably acquire and process heart rate, blood pressure, and respiratory rate signals, then pass the data to a microcontroller for further analysis and display. Here’s what I need from you: • Complete schematic capture based on my sensor and MCU selections • Four-layer board layout optimized for low-noise biomedical signals (Altium or KiCad preferred) • Manufacture-ready Gerber files, pick-and-place data, and a clearly structured BOM with medical-grade component choices • Design reviews at schematic and pre-release layout stages so we can make sure the board meets IEC 60601-1/-2 spacing, leakage, and isolation requirements • Brief ...

I need a PCB designed specifically for a one-off project; it is not part of a commercial product line, so flexibility and creativity are welcome. The board will carry only analog circuitry—no digital sections—centred around operational amplifiers and a small signal-processing stage I will detail once we start. What I will supply: the schematic (PDF or KiCad), preferred footprints, and basic mechanical constraints. What I need from you: a clean, manufacturable layout with proper analog grounding practices, complete Gerber/ODB++ files, a reviewed BOM, and the original design file so I can revise it later if needed.

I need a Pine Script v5 indicator for TradingView that runs primarily on the Gold (XAUUSD) 1-minute chart and gives me immediate, easy-to-read feedback on market turns. Core logic • Heikin Ashi analysis – detect both reversal patterns and real-time trend strength changes. • Doji recognition – spot classic Doji candles and treat each as a distinct event. Visuals & alerts Whenever a Heikin Ashi reversal or trend-strength shift is confirmed, the script should place a clear icon or background highlight on that bar. The same applies to each detected Doji. At the same moment, fire a TradingView alert() so I can route the signal to webhooks or mobile push. Extra context I still like seeing Fibonacci structure on screen, so please add a light retracement ov...

I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...

OVERVIEW The United Nations Development Programme (UNDP), the Seeker for this Innocentive Challenge, is searching for creative, affordable solutions that can safely detect and mark the presence of underwater explosive ordnance. In conflict or post-conflict zones, vast quantities of explosive ordnance (EO) lie submerged in oceans, lakes, rivers, and coastal waters. From post-WWII dumping to modern conflict spillover, these extremely hazardous explosives jeopardize the lives, livelihoods, and environments of nearby communities. UNDP is particularly interested in solutions that can be safely used by members of these communities, empowering them and enabling widespread knowledge of these dangers without requiring military or high-cost commercial interventions. The ideal solution will allow ...
