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. The freelancer’s main responsibility is hardware design and manufacturing outputs: schematic, PCB layout, Gerbers, BOM, assembly files, and firmware-ready hardware documentation. Firmware will be developed separately using AI/Codex/Claude from existing working ESP32 firmware. I will burn the firmware once the board is ready. The PCB must support first firmware flash...

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 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...

# 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...

Only For USA ( Texas preferable ) I need an experienced gas-turbine specialist who can log in remotely and walk me through diagnosing and correcting persistent startup problems and noticeable performance drops on one of our units.

I need help bringing a single-layer PCB back to life. At the moment it shows three clear problems: several components have failed, some traces are visibly damaged, and the board refuses to power up consistently. I can supply the original Gerber/layout files, but the schematic is no longer available, so part of the task will involve tracing the nets and inferring the missing circuit details. Your job is to: • Pin-point every faulty component and specify equivalent replacements • Locate and mend any open or shorted traces, or propose jumper fixes where copper is beyond repair • Restore a clean, stable power rail and verify correct voltage levels under load • Give me a concise repair log that includes measurements, photos of each fix, and final functional tests A ...

I have an online electrical and safety course that shows more 100 separate modules still outstanding. Everything is already built—short videos followed by a quiz in each section—so the only job is to work through them until the platform records every module as 100 % complete. You will receive my login, move at your own pace, and mark each quiz successfully. No writing, design, or extra content is needed; I simply need the course dashboard to read “completed” across the board. When you are done, send a quick screenshot or export of the completion page so I can keep it for my records. That’s all there is to it.

I’m ready to refresh my retail space in the 48038 area by swapping out a small run of ceiling fixtures—fewer than ten—for daylight-tone LED flat panels. The existing housings are already LED-ready, so this should be a straight replacement: remove the current panels, pop in the new daylight units, test, and tidy up. The work must be done during store off-hours (early morning or after close) so sales aren’t interrupted, and I’d like all debris hauled away once the job is finished. Please bring everything you need for a clean, code-compliant installation and verify each panel is firing at full brightness before you leave. I am specifically looking for a licensed and insured electrician with experience in commercial buildings. If you’ve handled retail ...

The square wave should have an equal mark-to-space ratio, a frequency equal to that of the resonant frequency of the metal bar estimated in Part 1, and an output voltage going from 0 volts to +15 volts. Show full working for calculating component values and draw the circuit diagram. Part 1 is measure the frequency response of one of the metal bars from the Electronics Lab. You will need to use the signal generator (function generator) and oscilloscope to do this. Plot the resulting frequency response across the range 100kHz to 200kHz, and state the resonant frequency of the metal bar.

I have a working concept for an E-Rickshaw diagnostic tool based on an ESP32 DevKit V1, and I now need a production-ready 2-layer PCB. All circuitry must operate from the vehicle’s 48 V line, stepped down via an LM2596. The board will drive an I2C OLED, measure battery voltage, and sense individual lines for the horn, headlight, indicators, brake light, and reverse buzzer. Two probes (A & B) are included for quick continuity tests. Good engineering practice is mandatory: reverse-polarity, fuse, TVS and general input protections must be designed-in. Preferred workflow • KiCad is my first choice; if you feel EasyEDA delivers clear advantages, let me know. • Layout decisions should favour ease of assembly over sheer compactness or extra thermal tricks. • Blueto...

I need a single partner who can handle three related plating jobs and deliver consistent, verifiable quality across each one. The parts involved are aluminium alloy wheels that must receive a bright nickel-chrome finish, mild-steel strip that needs a reliable nickel layer, and copper wires that call for a nickel-plus-tin deposit. The finishes serve all three classic purposes—eye-catching appearance, long-term corrosion resistance, and dependable electrical conductivity—so any method you propose has to balance these outcomes rather than optimise for just one. Because the parts come from different production lines, I will ship lots separately and expect you to return them with the following in place: • Nickel-chrome on the wheels with show-grade brightness, even coverage i...

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...

I’m building a compact, 4–6-layer mixed-signal board that will sit at the heart of a new sensor-interface product.

A pin header on my small production PCB was accidentally soldered one pad off its intended footprint, so the connector now sits in the wrong position. The task is straightforward: cleanly remove the existing header, clear the through-holes without lifting pads or damaging traces, and solder a new (or the same, if salvaged intact) header perfectly aligned to the original footprint. Because this is essentially a solder-joint-related rework, I expect professional tools—hot-air rework station, fine-tip iron, quality flux, microscope inspection—to be used. Once the header is resoldered, please verify continuity on every pin, check for bridging, and confirm the board still powers up. Deliverable: • Returned, fully functional PCB with the pin header accurately seated and all jo...
