Flex circuit design jobs
I’m ready to give my company a fresh visual identity and need a truly modern logo that feels clean, forward-thinking, and instantly recognizable. The exact colour palette and wording are still open, so you can flex your creativity as long as the overall look remains unmistakably modern. Here’s what I’d like from you: • At least three distinct initial concepts so I can explore different directions • One chosen concept refined through up to two rounds of revisions • Final artwork delivered in editable vector format (AI / EPS) plus high-resolution PNGs and a favicon-sized version All files should be fully scalable and suitable for print and digital use. Please share a brief note on your approach, any relevant portfolio samples that show your mod...
I’m refreshing my Android testing website and need a logo that immediately signals “reliable tech.” The look should be classic—solid lines and balanced proportions rather than ultra-minimal or trendy. Please work strictly with a green-and-black palette. Key creative cue: weave in tech-related imagery. Think circuit patterns, diagnostic symbols, or other subtle hardware/software references that evoke rigorous mobile testing. If you feel a light touch of Android iconography or a text element strengthens the concept, that’s welcome, but the technology motif must remain the focus. Because the logo will live everywhere—from the site header to social thumbnails—clean scalability is crucial. Vector artwork is therefore a must. Deliverables &bu...
I’m preparing a large-scale commercial build and need a seasoned estimator to turn my complete set of drawings into clear numbers I can trust. The stamped PDFs are ready to share, so you can dive straight into the plans and extract every length of conduit, feeder, branch circuit, device, fixture, panel and piece of supporting hardware.

I have a simple circuit that now needs a professionally routed PCB so I can move from breadboard trials to repeatable prototypes. The schematic is finished and tested; what I’m missing is the board layout, complete with tidy routing, sensible component placement, and manufacturing-ready files. The board is intentionally small—nothing that will stretch a panel—so this is a focused job rather than a sprawling multi-layer challenge. You may work in KiCad, Altium, Eagle, or another mainstream tool as long as the final output can be handed straight to a board house without extra tweaks. If you prefer specific design rules or trace/clearance standards, let me know so we stay on the same page. Deliverables I need at hand-off: • Source layout file in your c...
I need precise electrical panel layout drawings produced in AutoCAD.

Deliverables • Clean DWG files for every panel layout • Corresponding PDF sheets sized to ARCH D Acceptance will be based on: • Correct replication of all circuit information from the source files • Consistent layering and annotation style • Zero unexplained warnings or errors when the drawing is audited in AutoCAD Let me know your turnaround time and any si...
...drawings—so you will be creating a custom design from the ground up. Key requirements for the schematic • Use the exact components and then create BOM • Arrange them to match a particular circuit topology I will detail (net names, functional blocks, and critical path lengths). Layout expectations Once the schematic is approved, translate it into a PCB with clean, logical placement that respects signal integrity and keeps future routing straightforward. Board outline, mounting holes, and keep-outs are already defined; the creative work is positioning parts for optimal performance and assembly. Deliverables • KiCad 10 project files: .kicad_sch, .kicad_pcb, libraries. • PDF/PNG exports of the schematic and placement for quick review. &b...
I’m looking for a professional who can take full charge of installing a complete closed-circuit camera system—ten units at minimum, possibly more once we finalise the exact layout. The task spans everything from selecting suitable indoor/outdoor models, running the cabling, mounting the cameras, configuring the NVR and mobile viewing apps, through to a final hand-over walk-through so I’m comfortable with the system. Key points to note • Scope: CC camera installation only; no driving, fibre or general electrical work outside what the cameras require. • Volume: 10+ cameras, so efficient cable management, clean drilling, PoE switching (or equivalent power solutions) and neat termination are essential. • Hardware: I’m open to your recommende...
...interior walls. Some sections already have conduits you can fish through, while in other spots you will have to create fresh pathways without damaging finished surfaces. The job calls for neat, code-compliant routing, secure stapling or tray support in the attic, and proper termination at wall plates or junction boxes. Please bring the tools you normally rely on for this kind of work (fish tape, flex bits, low-voltage boxes, stud finder, tone tester, etc.) and supply any additional materials we agree on before you start.

What I’m looking for: • Complete schematic with part numbers that are actually obtainable • Optimised PCB layout and Gerber files ready for fabrication • A vetted BOM, costed if possible, plus transformer design data • Basic thermal and efficiency estimates so I know it will stay cool in a sealed panel • Startup and funct...
I am designing an outdoor P4 LED module that will be driven around a Chipone IC and I need a complete circuit developed for it. The goal is very clear: the board must display still images, videos cleanly and reliably on an 80 × 40 pixel matrix, even when it is mounted in demanding outdoor installations. Key points you should know • Functionality: image display only, no scrolling text or animated graphics at this stage. • Pixel matrix: 80 columns by 40 rows (a custom resolution that sits between the usual 64 × 64 and 128 × 128 panels). • Environment: the board will live in high-humidity, high-temperature and dusty locations, so component selection, conformal-coating recommendations and connector placement must respect that. • Core driver...
I already have a DWG containing the apartment floor plan and a rough electrical layout. What I now need is a seasoned AutoCAD user who can turn that working file into a presentation-ready drawing. The priorities are clear: • Clean up the existing layout so every circuit, fixture, and conduit path is easy to follow. • Boost overall readability by applying consistent, professional electrical symbols plus uniform text formatting and labels.
