I need a compact, production-ready PCB designed for a new consumer-grade smart-home device. The board’s core task is to handle a dedicated control-interface switch that will let users toggle the appliance on and off and cycle through a few operating modes. Space is not tight, so component selection and trace routing will be no problem. You’re free to work in Altium Designer, KiCad, or Eagle—whichever lets you move fastest while still delivering neat, well-documented files. If you choose RF-friendly parts, please keep the layout compatible PCB Easy or JLCPCB. Deliverables I expect: • Schematic and PCB layout files • Gerber, drill, and pick-and-place outputs ready for fabrication • A tidy BOM with supplier part numbers and current pricing • Assem...

I need a double-layer, signal-processing board laid out in Altium Designer and prepared for fabrication at JLCPCB. The finished board will fit inside a 15 cm × 15 cm envelope, so component placement, routing, and keep-outs should respect that medium-size constraint. Deliverables I expect: • Complete Altium project with schematics and PCB layout • Optimised Gerber, drill, and pick-and-place files matched to JLCPCB’s specs • BOM with manufacturer part numbers and assembly notes I will review the design by importing the files directly into Altium and running JLCPCB’s online DFM check; the job is complete once the files upload without errors and the board passes ERC/DRC.

I have three existing Altium Designer projects that must be refreshed before the next manufacturing run at JLCPCB. Both the schematic and the board layout need attention. On the schematic side I already know the exact edits: a handful of parts have to be added or removed, several nets must be reassigned, and a few voltage- and current-related values updated. Once those changes are in place the PCB layouts have to be brought in line—rerouting where required, keeping the original board outlines and mechanical constraints intact, and making sure every DRC/ERC check comes up clean. When the files are solid I need a full, ready-for-upload manufacturing package: • Updated Altium project files (.PrjPcb, .SchDoc, .PcbDoc) • Gerber and NC-Drill set generated with JLCPCB’s ...

I need a robust arc-suppression circuit engineered specifically for my RF welding machine. The goal is simple and non-negotiable: stop destructive arcing before it reaches the generator or matching network, protecting the entire system from costly downtime and repairs. Key points you should know up front • Purpose: prevention of equipment damage only—operator safety circuits are handled elsewhere. • Architecture: solid-state components throughout; no relays or mechanical contacts. • Ratings: I will share the operating voltage and current range once we start, so your design must be adaptable within those limits. What I expect to receive 1. Schematic with clearly labeled protection stages (detection, quench, reset). 2. Bill of materials with manufacturer p...

I have a commerical infrared device I want to push beyond its stock limits by unlocking and fine-tuning the voltage-gating parameters, and explore any additional user-interface controls that govern current (U/I).

I will verify this from the final performance plots, so please present both power-output and gain data together in clear scatter-plot format. Alongside the simulation results I need production-ready DXF files of the matching PCB layouts. Keep the drawings aligned with recognised industry standards so they can move straight into fabrication without extra re-work. Deliverables 1. S-parameter models (touchstone) and any suppor...

I need a concise Python 3 script that will run on a Raspberry Pi 5 and do the following: • Watch a single GPIO input line for the HIGH digital signal coming from my Sony camera’s built-in AI output. .

I need an experienced electronics engineer to analyze the existing design and redesign it into a much smaller PCB. The new design must maintain similar electrical performance but reduce the physical size so it can be mounted directly on the piezo sensor and permanently sealed with epoxy resin inside a capsule. Primary Objectives 1. Analyze or replicate the functionality of my existing piezo preamp. 2. Redesign ...

I have a new IoT datalogger concept and need a full-fledged PCB layout that is ready to send straight to fabrication. The schematic is not fixed yet, so I’m relying on your board-level expertise to translate high-level requirements into a clean, production-ready design. What I already know • Form factor: credit-card sized (roughly 85 × 55 mm, single board). • Core: a low-power MCU or module capable of handling multiple digital and analog inputs. • Future-proofing: headers or pads for common temperature, humidity, and pressure sensors as well as optional wireless modules (Wi-Fi, Bluetooth, or cellular—final choice can be discussed once power budget is clear). • Power: ability to accept both rechargeable battery input and external DC (buck/boost circuit...

I have an Arduino-based board that is powered from its own DC rail, yet it has to monitor several other DC lines whose grounds are completely separate. Right now I’m simply feeding each line through a voltage divider, and—unsurprisingly—the readings jump around or drift because the grounds are floating. The symptom is clear: inaccurate voltage readings that make the data unusable. What I need is a clean, reliable way to sense those isolated DC voltages without tying the reference points together. Whether that means introducing isolated amplifiers, optocouplers, tiny transformers, or another proven technique is up to you; I’m open to whichever approach gives stable, repeatable results and keeps the measurement side safe for the microcontroller. Here’s what I&...

I need help turning three off-the-shelf modules now sitting in my glasses prototype—a USB 2.0 hub, a USB audio codec (mic plus stereo out) and a dual-channel Class-D amplifier—into one long, narrow board that can slide inside the temple arm. The space I have measured is roughly 80 mm × 15 mm, so the layout has to be linear rather than squarish, with components placed to keep the height profile as low as practical. The board will run exclusively from the host’s 5 V USB rail; no batteries or additional supplies are planned. Because this is for voice prompts and basic media playback, a standard-grade codec is fine—I’m not chasing audiophile specs, just dependable microphone input and clean stereo output that won’t hiss or pop when the amp is idle. A...

I want a simple two-channel radio link that can do just two things reliably: 1) vary the speed of my brushless DC motor through its ESC (accepts S-Bus or standard PWM) and 2) toggle a single relay on or off. Hardware • I already have the motor, ESC, and relays. • You may choose Arduino, Raspberry Pi, or any Adafruit board—use whichever keeps the build small, inexpensive, and stable. Radio requirements • The handheld transmitter must let me select the operating band with a physical switch: 2.4 GHz, 900 MHz, or 433 MHz. • If LoRa is the cleanest way to hit those bands, great—just make sure the LoRa hop gives me at least a 1 000 ft (≈300 m) clear-line range. Long-range reliability is more important than data rate or extreme power savings...
