I need a purpose-built PCB for an APAS control system that will ultimately drive a small embedded platform. The board must be laid out on two copper layers and should balance tight signal integrity with compact mechanical footprints, as space inside the enclosure is limited. You’ll start from a functional block diagram and a rough schematic I already have on paper. Component selection is mostly open, so feel free to optimise around availability and cost. I’m comfortable with Altium Designer, Eagle, or KiCad, so use whichever environment lets you work fastest; I only ask for the native files along with the usual production outputs. Deliverables • Cleaned-up schematic ready for review • Final two-layer through hole PCB layout (230 mm × 130 mm target size) ...

The job is to turn a very small, single-sided board—35 mm × 23 mm, 1.5 mm thick—into a full Gerber package ready for fabrication. The layout is straightforward: one reed switch, a single copper track, and two solder lugs. You will work from the material I already have: clear photographs of the prototype and a dimensioned PDF that came out of my AutoCAD workflow. No special manufacturer or industry rule set is required; just follow standard defaults that any board house can accept. Deliverables I need back: • RS-274X Gerber files for all layers (copper, solder-mask if used, silkscreen if needed, and board outline). • Excellon drill file. • A quick read-me confirming layer naming and the units you used. Once I receive those files, I should be able to u...

I have several single-layer printed circuit board that has stopped performing reliably. Several symptoms point to multiple underlying faults: a few components no longer behave as expected, some traces appear open or damaged, and certain connectors intermittently lose continuity. Unfortunately, I do not have the original schematic or any Gerber/design files, so the job will require hands-on troubleshooting and a bit of reverse-engineering. Here’s what I need from you: • Locate and replace or re-solder the malfunctioning components. • Identify and restore any broken or lifted traces so every signal path is solid. • Resolve the intermittent connection issues at the board’s headers and edge connectors. • Once the board is fully functional again, capture ...

I already have a complete STEP-format CAD model of my foot massage device and have sourced the key parts I’d like to use inside it.

Core features to implement • Adjustable pressure driven by a compact motor system • Consistent, safe heat therapy integrated into the same housing Scope of work You will review my CAD, confirm that the components I’ve chosen truly fit the envelope, then design and build the electrical architecture that powers both features. This includes creating the schematics, selecting any supporting parts I may have missed (drivers, temperature controllers, safety fuses, wiring gauges, connectors), and...

I have completed the schematic and multilayer PCB layout for a custom GNSS / GPS module that will sit inside a small-form-factor UAV. Before I press the “order” button, I need a second set of expert eyes to validate every critical detail, with extra attention on the power-supply architecture—which I flagged as my primary concern. The review should cover GNSS/RF trace routing, impedance control, grounding strategy, EMI/EMC risk points, component placement for manufacturability, and overall reliability under airborne vibration and temperature swings. If you spot an issue, I expect you to offer (and, if we agree, implement) concrete fixes so the board comes back right the first time. Design files are proprietary; I will share the Altium project after I see examples of ...

I already have a complete schematic for a multi-function meter built around the STM32H743BIT6. Before I move to PCB layout I need a fresh set of eyes to refine the design, swap a few key parts, and fold in two new capabilities. Work required • Correct any schematic errors you spot (net ties, pin assignments, power flags, ERC issues). • Replace the specified parts—new values for several resistors and capacitors plus an updated pin-compatible MCU revision. • Add extra sensing channels and tighten the power-management section so the board runs cooler and meets my standby-current target. • Schematic circuit diagram design and PCB Design in Altium software. We may provide Altium software. • Simulation required in Proteus software. We may provide software. &...

Dear Sir/Madam I'm looking for an experienced motor cum EM design engineer to independently sanity-check a set of motor designs we've developed for UAV outrunner applications (BLDC/PMSM, up to ~3 kW). I don't need a redesign — just your expert judgment on whether each design is: 1. Physically feasible — geometry, winding, magnetics, and materials are self-consistent and buildable. 2. On-target — the claimed performance (torque, Kv, efficiency, losses, temperature) is realistic and consistent with the stated geometry/operating point. 3. DFM-compatible — manufacturable with standard lamination/winding/magnet processes (slot fill, tooth/yoke widths, magnet sizing, airgap, tolerances). I'd share a results pack per design: dimensions, w...

I'm seeking an experienced audio engineer to design a dual-output audio processor with two voltage-controlled frequency boundaries. This device will split an incoming audio signal into two paths DEPENDENT upon audio frequency for live performance use, and needs to support both analog and digital output formats.

I have two BLDC motors running on VESC-based controllers and I need them responding smoothly to a radio-frequency hand-held remote. The goal is true “tank style” drive: forward, reverse, pivot left or right, plus proportional speed and braking on each trigger. Here is what I still need done: • Bind and map the RF receiver to both VESCs so every channel on the remote translates cleanly to speed, braking and direction. • Set safe current limits, regenerative and active braking parameters, and be sure neither motor over-currents under stall conditions. • Calibrate RPM and refine torque curves so the response is even across the whole throttle range. • Synchronise the two controllers over CAN so they act like one power-train without cogging or desync a...
