I have a fully-captured schematic that now needs to become a clean, reliable, two-layer PCB laid out in Altium Designer. The board is for an educational project, so component placement must favour easy hand-soldering and troubleshooting while still meeting good manufacturing practice. Here is what I am expecting: • Thoughtful SMD and through-hole placement with clear silkscreen labelling • Optimised routing, copper pours, and sensible track widths/clearances • Thermal relief and high-current considerations where required • Compliance with the specific manufacturing rules and stack-up I will supply Deliverables: 1. Altium project files (fully editable) 2. Gerber, NC Drill, solder-mask and paste layers ready for fabrication 3. Pick-and-place file plus update...

The schematic for my project is finished; what I need now is a clean, production-ready two-layer PCB designed in Altium. Every component on the board is through-hole, so pad sizes, hole diameters, annular rings and keep-outs must favour easy hand-soldering while still meeting modern fabrication standards. I do not yet have a specific manufacturer in mind, so I will rely on you to recommend practical design-for-manufacture rules (trace widths, clearances, drill limitations, etc.) that suit common low-volume board houses. Please fold those constraints into the layout from the start rather than treating them as a post-process check. Good thermal relief on large copper areas, sensible power/ground routing, and a tidy silkscreen with readable reference designators are essential for inspectio...

I have the complete schematic for an industrial-grade control board and now need it laid out as a two-layer PCB that can be sent straight to fabrication. The board will carry a mixed population of surface-mount and through-hole parts, so clear separation of assembly zones and sensible routing between the two technologies is essential. Here is what I need from you: • Convert my schematic into a neat, manufacturable layout that respects standard clearance rules for industrial equipment. • Optimise component placement for efficient heat dissipation and easy hand-solder access to the through-hole parts. • Provide all production data—Gerber, drill, solder-mask and paste layers—along with a pick-and-place file, updated BOM and the editable project file in your...

I’m putting together a small, stand-alone digital hygrometer that simply shows real-time temperature and relative humidity on an LCD. No Bluetooth, Wi-Fi, or data-logging complexity is required—just accurate sensing, a clear screen, and reliable operation. Here is the essence of what I need: • Accurate temperature and humidity sensing (±0.5 °C / ±3 % RH or better is ideal). • An easy-to-read, low-power LCD that presents both values at a glance. • Clean firmware that boots quickly and updates readings at a sensible interval without flicker. • A compact electronics design I can send straight to fabrication: schematic, PCB files, BOM, and a brief assembly/testing guide. If you have a preferred sensor family (SHT3x, BME280, DHT series, ...

I have the core idea for a new board and now need the full circuit design translated into a clean, fabrication-ready PCB layout schematic. The project is strictly circuit-design focused: from refining the schematic to producing professional-grade PCB artwork that any standard board house can manufacture. You will start with my rough concept and component list, confirm critical specs (voltage rails, signal integrity, mechanical keep-outs), then create: • A complete, editable schematic (Altium Designer, KiCad, or Eagle—whichever you prefer and own a license for) • Layer-stack definition and board outline that respects my size constraints • Optimised component placement and routing, observing best-practice DRC and EMI/EMC guidelines • Gerber, drill, and pick...

Description I need one physical prototype assembled from a complete, tested design. This is a hands-on build — soldering, basic fabric mounting, and loading provided code — with no design work. Everything you need is written down: a parts list (~$80), a wiring diagram, a belt layout drawing, the two microcontroller programs, and a three-step verification procedure. What you'll build A wearable elastic belt carrying six small 3V coin vibration motors, each glued into a small rigid pod and Velcro-mounted so it can be repositioned. The motors are driven by a BBC micro:bit v2 through a ULN2003 driver chip, powered by a 3×AA pack, housed in a small pouch or box on the belt. A second micro:bit v2 serves as a handheld controller and talks to the belt over the micro:bit&#...

I already have a fully-verified KiCad schematic for a small industrial power supply and now need the actual board laid out. The goal is to squeeze the design into the smallest practical footprint without compromising functionality, so every millimetre saved counts. All parts must sit on the top layer only; the underside has to stay completely flat for mechanical clearance and easy heat sinking against a metal chassis. Because of that mechanical requirement, I want to stick with standard through-hole vias rather than blind, buried, or micro solutions. Here’s what I would like you to handle: • Precise component placement that respects the single-sided assembly constraint. • Clean, compact routing that keeps the overall dimensions as tight as possible while meeting manufac...

I need a complete set of KiCad schematics drawn from scratch for a fairly large, multi-board concept. The job is limited to the schematic stage—no PCB layout—yet the design is dense, with a high component count, multiple power rails, and several digital-analog interfaces that must be kept well organised through hierarchical sheets. I will supply a first batch of parts: CPUs, power converters, key connectors and a few specialised ICs, each with its electrical characteristics and a preferred footprint. The remaining devices—discrete passives, protection components, odds-and-ends ICs—still need library symbols created or matched to existing KiCad libraries, along with suitable footprints. Whenever information is missing, I will point you to the relevant datasheets; yo...

I’m building a compact entertainment gadget dedicated to high-quality audio playback and I need a complete PCB designed from scratch.

I am moving a hardware project from concept to production and need a KiCad specialist to work alongside me through schematic capture, PCB layout design, and library management. The current schematic is still in its initial draft, but I have already documented every functional block, net constraint, and mechanical boundary in a detailed requirements PDF that I will share as soon as we start. Your first task will be to review and clean up the draft schematic, verifying component choices and flagging any electrical or footprint conflicts. From there we will: • Finalise the component libraries, adding any missing symbols or footprints so the project remains self-contained and version-controlled. • Complete the PCB layout to match my stack-up, keep-out zones, and routing guideline...

I have a hand-drawn circuit diagram that now needs the full KiCad treatment: a clean, conventional schematic, properly assigned footprints, a 3D board render, and final Gerber files ready for fabrication. The project is for my own personal use, so I’m happy to discuss component selection rather than lock you into any specific brands.

I have a complete controller-level Bill of Materials that includes microcontrollers, capacitors, position sensors, IPMs, N-channel MOSFETs and IGBTs. The immediate goal is to drive the overall cost down without sacrificing reliability or long-term availability. Most of the boards now work with a mix of TI, Infineon, yageo, ATMEL, Microchip and STMicroelectronics devices, but I’m open to shifting to any pin-compatible or firmware-friendly alternative if it meaningfully trims the price. The same mindset applies to passive and power parts: if you can source a spec-matched capacitor, MOSFET or IGBT that lowers the piece price and is easy to get from the usual sources - China/Taiwan and their local distributors in India, i am open to it. Would prefer a Chinese/Taiwanese national who ca...

I’m putting together a small-run prototype board focused on digital signal processing that also needs onboard wireless connectivity. The goal right now is to capture a clean, production-ready schematic that I can pass straight into layout once the parts are locked in. Here’s what you’ll be working with: • 100 % digital component set—no analog front ends this time. • Core functions revolve around real-time signal manipulation plus low-power wireless links (think BLE, Wi-Fi or similar; I’m open to whichever stack fits best). • It’s strictly a development board, so easy probing, test headers and clear silkscreen labels are important. What I need from you: 1. Complete schematic in KiCad, Altium, Eagle or another well-known CAD tool. 2....

This project involves updates to signal processing, and possible EMI compliance updates on an existing board. The PCB has already passed Part 15 emissions, but there is reason to think it may not pass CE. The successful candidate will possess, at minimum, a BSEE and extensive experience with Altium. The specifics are adding a dual analog switch to low noise signals for a musical instrument. Some existing components may need to be moved. We are specifying US based freelancers only.

I need a custom mixed-signal circuit engineered from the ground up to drive an optical wireless communication link. The design must cleanly blend an accurate analog front-end—handling photodiode receive and LED/VCSEL drive stages—with the required digital processing blocks for modulation, clock recovery, and protocol framing. My priority is signal integrity across the entire chain: low-noise transimpedance amplification, precise ADC/DAC selection, and robust high-speed PCB layout that minimises jitter and EMI. Component choices should be commercially available and cost-effective for a small production run. Because the target is an optical wireless channel rather than Bluetooth, Wi-Fi, or Zigbee, you are free to choose or recommend the most suitable modulation scheme (e.g., ...

An electrical schematic now exists only as a digital image and must be recreated as a clean, fully editable drawing. The task is strictly a redraw—no changes to the circuit itself—so every symbol, wire number, reference designator, and note has to match the original image exactly. Use any mainstream electrical-CAD platform you are comfortable with (AutoCAD Electrical, EPLAN, OrCAD, etc.); just be sure the drawing complies with standard drafting conventions and layer discipline so it can be maintained later. Deliverables • Native CAD file of the finished schematic • A print-ready PDF generated from that file Before hand-off I will spot-check key nets, component labels, and title-block data against the source image to confirm accuracy and completeness.

I need a compact controller board built around the STM32F103CBT6 in the 48-pin LQFP package (or a pin-compatible alternative with the same Cortex-M3 core). The board must expose three independent serial channels: • RS-485 • RS-232 • A UART linked to an on-board serial-to-TCP module that speaks plain TCP/IP Reliability is critical. Please integrate proven over-voltage, short-circuit and over-current protection on all power inputs as well as the three interface blocks. If you are more comfortable substituting a different F1-series part with identical footprints, that’s fine as long as the firmware and pinout remain drop-in compatible. Deliverables • Complete schematic (Altium, KiCad or EasyEDA) • Four/two -layer PCB layout with proper isolation be...

I’m looking for an embedded-systems engineer who can take ArduPilot’s AP_Periph codebase and turn it into a robust CAN-bus battery monitor. The unit will sit on a DroneCAN network and stream full MAVLink telemetry, so it can slot straight into my existing ground-station setup without any extra protocol bridges. Integration with other telemetry options such as or SmartPort isn’t needed right now. Key functions I must see on the bus: • High-accuracy individual cell voltage for every cell in the pack (not just pack voltage) • Hall-effect current sensing that stays linear and low-loss all the way to 400 A • Standard AP_Periph health, identification and parameter handling so the flight controller recognises the device instantly Deliverables 1. Schemat...

Our sports venue runs on an ageing electronic scoreboard built around seven-segment LED and P10 LED panels. It still works, but erratically, and it can only be operated from the hard-wired control box bolted under the grandstand. I need the whole system modernised so I can walk onto the field with a phone or tablet and run the show from there. Scope of work • Inspect every board, power rail and driver on the existing hardware, replace any damaged or obsolete parts, and leave the display fully refurbished. • Design and build a new controller unit that adds rock-solid wireless connectivity plus a battery-backup circuit so a brief power loss never blanks the screen. • Write clean firmware for that controller, making sure it can address both the seven-segment digits and t...
