...lights for balance. Outdoors, the concept is simpler but just as important: ground-mounted fixtures ringing the villa to emphasize its architecture and create a welcoming glow from every angle. You’ll receive my CAD floor plans, ceiling heights and a few reference photos as soon as we start. From there I’m counting on you to calculate ideal fixture counts, beam angles, placement distances and circuit grouping so that the final layout is both practical and visually polished. Deliverables • Scaled lighting plan for every interior space and the full exterior perimeter • Fixture schedule naming manufacturers, model numbers, lamp types and wattages • Load summary suitable for hand-off to the electrical contractor • Basic 3D or rendered vie...

I’m looking to have my home’s existing electrical system brought up to scratch. The job is limited to revising the current wiring runs and the circuit-breaker setup; no full re-wire or cosmetic fixture work is needed. Key goals • Replace or re-route any wiring that cannot safely handle the present and planned loads. • Reconfigure the main panel so the breakers match the new demand and trip correctly. • Increase overall capacity to accommodate additional appliances while keeping everything fully compliant with the latest Philippine Electrical Code. Please address all safety issues you find and document how each change satisfies local standards. Final deliverables I expect are: 1. Updated single-line diagram and panel schedule reflecting new brea...

...input power, drive status LEDs and, when a brown-out is detected, shut the rails down in a defined sequence after the battery grace period. I will flash the MCU here, so please include well-commented source, compiled HEX and a simple serial or GPIO interface for configuration. Electrical safeguards are critical in the factory environment, so integrate robust overcurrent, overvoltage and short-circuit protection on every output as well as reverse-polarity protection on the battery input. Thermal considerations, adequate copper weights and clear separation of power and logic grounds all need to be reflected in the layout. Deliverables • Complete schematic (Altium, KiCad or Orcad) • PCB layout and Gerber/NC drill files ready for fabrication • Annotated BOM w...

I’m building a new circuit in Autodesk Eagle and want an experienced Eagle user to look over my schematic, walk me through any weak spots, and suggest best-practice improvements before I move on to the board stage. The goal is a rock-solid schematic that is ready for PCB layout, free of hidden ERC errors, and organised with clear net labels, correct device libraries, and sensible part choices. Here’s what I need from you: • A shared review session (screen-share or annotated feedback) to examine the current Eagle *.sch file. • Actionable recommendations on component placement, net naming, and library management. • Corrections or edits made directly in the schematic file, returned to me with brief inline notes so I understand every change. • ...

...settings (no manual knobs). The job is split into two clearly defined stages: • Level 1 – Schematic & Magnetics: I need a complete circuit schematic, transformer and inductor calculations, protection strategy, and a verified simulation that proves the design meets current, voltage, and timing targets. Please work in Orcad or Altium—as long as the files open cleanly in one of those tools, I’m happy. • Level 2 – Proof of Concept: Once the schematic is signed off, we move to a hardware demo that reproduces the specified pulse train on a real load, together with measured waveforms and a brief test report. Payment is tied to each stage, with a modest slice for the design package and a larger one once working hardware is validate...

...translate story, market positioning, and projected returns into a compelling pitch deck, one-sheet, and budget top-sheet. If you can tap an existing network, even better; if not, proven experience building an investor list and reaching out strategically is essential. Because the goal is festival traction, I also value your ability to shape a festival rollout and show investors how exposure on the circuit feeds the larger feature’s prospects. Key deliverables: • Finance roadmap, including budget breakdown and investment structure • Investor-ready pitch deck and supporting documents (one-sheet, look-book, timeline) • Curated list of qualified investor leads with contact strategy • Draft investment agreements or term sheet (template is fine) •...

I’m getting ready to spin up a prototype and need an experienced PCB designer to turn my schematic into a clean, single-layer board that will end up larger than 10 cm × 10 cm. I’ll provide the circuit diagram along with a few placement preferences; from there you’ll handle footprint selection, component placement, manual or auto-routing (whichever gives the most reliable results on a single copper layer), and all the usual design-rule checks. Because this is strictly for prototyping, I’m less worried about space savings and more concerned with trace clarity, manufacturability, and easy debugging. Standard through-hole parts dominate the BOM, but a couple of SMD footprints may appear—nothing exotic. If you normally work in KiCad, Altium Des...

I need a complete schematic for an analog circuit that will be used in a signal-processing application. My focus right now is solely on the schematic stage—no board layout or routing is required at this point. You will start from a functional description that I will provide (target bandwidth, expected input/output levels, and available supply rails) and turn it into a clean, well-documented schematic that can later be handed off for PCB layout. Proper component selection, clear annotation, and ready-to-simulate design files are essential. Please work in a mainstream CAD tool such as Altium Designer, KiCad, or OrCAD—let me know which one you prefer so I can confirm compatibility. The final hand-over should include: • The editable source file in the cho...

I need a seasoned electrical / electronics engineer to take a voltage stabilizer for industrial equipment all the way from concept to a be...bench results and move to pilot production. • Ongoing guidance while I build and debug the first hardware sample. If firmware or digital control is the best way to meet the spec, include concise, well-commented code and in-circuit programming instructions; otherwise a purely analog approach is fine. Safety standards for industrial environments—as well as sensible thermal management, short-circuit protection and over-voltage shutdown—must be baked in from the start. Please tell me about similar power-electronics projects you have completed and let me know which design tools you prefer. I’m ready to kick o...

I will supply a complete schematic, dimensioned drawing, and parts list for a small 90 × 190 × 40 mm panel that holds four illuminated push-buttons, two status LEDs, a few relays/diodes, and screw-terminal break-outs for power plus two simple on/off inputs. Every component value, wire gauge, and mechanical placement is already locked down; there is no design work left to do. Your task is purely hands-on: build one fully-functional unit exactly to the drawings. I’d like the circuitry laid out on stripboard (or another point-to-point method you’re comfortable with), all joints soldered, and the harness inside the enclosure bundled neatly for strain relief and easy future service. The case itself should be plastic, as noted in the documents. Before shipping th...

Lean more into athletic minimalism, data-informed geometry, or sharp editorial typography. I...

I already have a complete schematic for my single-phase energy-monitoring circuit; what I need now is a production-ready PCB layout that faithfully follows it and fits the enclosure I have chosen. The board must match the exact outline and mounting-hole pattern of my reference enclosure, so you will get the enclosure model and mechanical drawings from me on day one.

I need a compact PCB that triggers an MFA90A thyristor shortcircuiting a PV string (300 V DC). The board’s purpose is to short-circuit the PV panel and automatic re-triggering whenever both the control relay is set and PV voltage are present (during day, after night) Key technical notes • Input: PV string voltage ~300 V DC, so an on-board regulator must generate a stable low-voltage rail for the gate-drive circuitry and logic. • Switching device: MFA90A (SCR-class thyristor). Diode in series with the string, thyristor shortcutting. • Trigger source: dry-contact relay set by external signal • Operation: if the relay is closed when voltage on the PV line appears (morning), the board must re-fire the thyristor.. • Robustness: components, PCB clea...
