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 have a 16-channel relay board that must be driven by an Arduino. Each of the sixteen micro-switch inputs will correspond to one—and only one—relay output. When a switch is pressed the matching relay should energise for a fixed pulse of 2-3 seconds, then drop out automatically; there is no need for the user to alter that timing. Here is what I need from you: • Clean, well-commented Arduino sketch that reads the 16 discrete inputs, debounces the switches, and fires the appropriate relay for the required duration. • Pin-mapping and a simple wiring diagram so I can connect everything without guesswork (I will be using a common 16-relay module that accepts active-LOW signals, but please keep the code flexible enough to invert logic if needed). • Guidance on a...

I want to bring a compact, consumer-friendly utility gadget to market and need an engineer who can take it from idea to production. The core of the device is simple: when triggered it must emit a clear, audible beep, making it useful as a quick-locate or alert tool. Beyond that single function, everything should be engineered for reliability, low power draw. Here’s the scope as I see it: • Electronic and industrial design: refine my concept, choose components, and build a working prototype that delivers the beeping feature consistently. • Connectivity & app: create a lightweight companion app for both Android and iOS (Bluetooth Low Energy is fine) so users can trigger or silence the device from their phone. Or it can be connected through Google Home or Smartlife &...

I need an experienced embedded hardware / PCB engineer to design a production-ready STM32-based main controller PCB for a therapeutic massage/spine bed system. This is a build-to-spec project. I already have a detailed engineering handoff package including system architecture, old PCB references, estimated current budget, pin maps, connector notes, BOM guidance, firmware handoff notes, layout requirements, and test plans.

# FastForm Capacitive Sensor Electrode — PCB Design & Order Brief --- ## Overview I need a **very simple 2-layer PCB** designed and manufactured. Two variants, 5 boards each. **This board has no components, no traces, no schematic, and no routing.** It is four copper rectangles and three vias. Someone competent with KiCad should complete the layout in under an hour. **Important context so the design decisions make sense:** this is not a normal circuit board. It is a **capacitive sensor electrode** that will be immersed in wet concrete. The **solder mask is a functional dielectric layer**, not a cosmetic finish. Several instructions below will look unusual for a PCB — please follow them exactly rather than applying normal PCB conventions. --- ## Deliverables 1. **KiC...

I’m developing a compact, sensor-based water leak detector and have already finished the schematic. Now I need a specialist to turn that schematic into a production-ready board layout and clean Gerber package. Scope • Translate my existing schematic into a neat, single- or double-layer PCB that keeps overall dimensions small (the enclosure footprint is 40 mm × 60 mm). • Optimize trace routing for a low-power, battery-operated design; key nets carry no more than 3 V. • Include pads for the water sensor probe, a low-power microcontroller (I’m currently leaning toward an STM32L series but can adapt if you know a better fit), an LED indicator, piezo buzzer, and test pads for programming. • Provide advice on component placement to minimize false po...

Hi there! Hope you're doing well. I have a hobby-grade RC truck (thinking Traxxas Stampede or a similar 4WD model) and I'd love to turn it into something I can drive remotely over the internet — not just the usual short-range radio control, but actually control it from another country, with minimal delay. The basic idea is to swap out the stock RC receiver for a Raspberry Pi (or something similar), so instead of a normal remote, I could control it through a simple web page or app from anywhere with an internet connection. A few things I'm hoping you can help with: Getting the Pi talking to the truck's existing motor controller and steering servo Setting up a low-latency connection (something like WebRTC) so the controls feel responsive even over long distances A s...

I need a working human-computer interface that can both pick up and broadcast data over Bluetooth at the highest speed the protocol allows. The data flowing through it will be full-rate cellular communications data rather than simple audio or text, so throughput and low latency are critical. On the input side the unit will read Qi energy and Acu-meridian energy via harness-style skin contacts. Those raw sensor signals have to be conditioned, digitised and pushed straight to a tablet over Bluetooth without noticeable lag. In the opposite direction the tablet will be able to transmit control or stimulation patterns back to the interface just as quickly. The job covers hardware design, embedded firmware and a basic demo app for a tablet or computer: • Hardware: schematic, PCB layout an...

Please Note: total amount is $80. Please do not bid if this is not acceptable. I’m putting together a single-rail power supply for sensitive audio gear and need a clean, hum-free output. The brief is straightforward: • Topology: prefer an LDO-based regulator front-ended by a capacitance-multiplier stage (or an equally quiet alternative you can justify). • Input: board-mounted, fully encapsulated transformer—no off-board or open-frame types. • Output: 9 V to 24 V DC, up to 1.5 A continuous. Low ripple and broadband noise filtering are far more important than absolute efficiency. Include transformer snubbers. • Target use: high-end audio equipment, so 50/60 Hz mains-borne noise, switch-spikes and thermal drift must all be kept to a minimum. Deliverable...

We are looking for an experienced Power Electronics Engineer / PCB Design Engineer to design three high-power solar inverter systems from scratch: On-Grid (Grid-Tie) Inverter Off-Grid Inverter Hybrid Inverter Power rating: 30kW to 50kW — this is industrial-scale, three-phase equipment, not a residential 1-5kW unit. We need engineers who have specifically worked at this power level before. We will start with one inverter type first (to be confirmed after proposals), then move to the others upon successful completion. We have reference datasheets/manuals from existing market products (ASHAPOWER, TruePower, UTL, Waaree, etc.) that will be shared as benchmarks for specs and features. The design itself must be original/from scratch — not a copy of any existing product. Delive...

I need help configuring a Hikrobot camera using python whenever it flags a vehicle incorrectly, drives an external alarm output. In practice that means: • Monitoring the confidence/result coming from the camera (SDK, ONVIF events or RTSP overlay—whatever is most reliable) and deciding when a detection should be considered “wrong”. • As soon as a wrong detection is confirmed, toggling the camera’s I/O port (or a small companion relay module if the onboard I/O proves too limited) to fire the alarm signal. A concise set-up guide and any scripts, firmware tweaks or parameter files you create must be supplied so I can replicate the installation on additional units. Please include short test footage or logs proving that the alarm is triggered only on false...

I need a compact Bluetooth mouse engineered from the ground up with four physical buttons, a smooth scroll wheel, and a USB-C port for both charging and optional wired use. Beyond the standard right- and left-click, the two extra buttons have to ship pre-mapped to volume control (up / down or mute / un-mute) yet remain fully re-programmable through companion software or firmware so users can assign any shortcut they like later on. The build should feel as solid as today’s premium portable mice, keep latency low, and work cross-platform without separate drivers. I’m open to Nordic, Cypress, or similar Bluetooth LE chipsets as long as you hit excellent battery life and achieve seamless reconnection after wake-up. USB-C power management and over-the-air firmware update capability...

I need a complete PCB design built around the ESP32-C3 and five onboard power MOSFETs. The board will sit inside a medium-sized, handheld consumer-electronics enclosure and run from a regulated mains-derived supply, so careful attention to isolation, creepage, and thermal paths is essential. The circuit will drive five independent high-side or low-side loads (I can adapt to whichever topology is simpler on your end) while giving the ESP32-C3 solid Wi-Fi/BLE antenna performance. GPIO pin mapping, level-shifting, protection, and a clean 3 V3 rail must all be worked into the schematic. Please route with sensible trace widths, keep EMI in check, and leave me a little proto area for future tweaks if space permits. Deliverables • Schematic and well-annotated PCB layout • Gerber, ...

I am looking for an experienced PCB layout engineer to design and route a compact, dual-layer PCB for an IoT smart switch module.

Deliverables: - Schematic review and optimizat...

Our ESP32-based prototype uses the MSME INNP441 digital mic, and during live audio streaming it introduces jitter and a screeching interference noise—even though the board sits in a quiet lab. I have already updated the firmware, swapped in fresh hardware, and tweaked every software register I could reach, yet the distortion persists. I’m looking for someone who can dive into the existing C/C++ (Arduino-style) code, analyse the I²S configuration and clocking, and track down whatever is corrupting the audio path. If a schematic or logic-analyser trace is helpful, I can supply both. Any fix should leave us with clean, stable voice capture that we can push straight to our streaming stack. Because this is part of our in-house tech, I will provide the full repository only a...
