This project strictly requires hands-on prototyping, including physical assembly and testing—design-only services will not be considered I already have detailed winding diagrams, coil counts, wire gauges, and a full wiring schematic for three compact electromagnets—each under 10 cm in any direction. Your task is to turn these drawings into a tangible proof-of-concept and ship it to me. The magnets will sit in a custom harness. I’m leaning toward a light alloy or other metal solution, but I’m open to your recommendations once you see the design constraints. All electronic components, fasteners, and raw materials will be reimbursed at cost; please keep receipts. Power can come from batteries, a small AC supply, or a rechargeable pack—I’m happy with whichever option best matches your workshop setup and meets the performance targets we’ll discuss. Deliverables * Three fully wound, insulated, and terminated electromagnets built to the supplied spec * Matching harness, machined or fabricated to precise dimensions, ready for mounting * Basic bench test results: resistance, current draw, and pull force at the chosen voltage * Photos or a short video showing operation prior to shipment * Secure packaging for safe delivery Once this prototype meets the agreed-upon metrics, there’s a larger program waiting, so flawless craftsmanship and clear documentation are essential. I look forward to collaborating and seeing these magnets spring to life.

As a seasoned mechanical engineer with hands-on experience in circuit design and electrical engineering, your small electromagnet prototype project resonates with my skillset. I've reviewed your detailed diagrams and wiring schematics, and I'm confident that I can transform them into reliable, tangible electromagnets crafted to your specifications. My extensive background includes creating intricate designs for custom harnesses from both light alloys and other metals, making me fluent in determining the best materials to match design constraints. In addition, my proficiency in utilizing multiple software, such as Rhino and Tekla, will enable me to fabricate your prototype to precise dimensions accurately; ensuring an optimal fit for smooth & secure mounting. I have a fully-geared workshop at my disposal. This means you have the flexibility to choose the power source that best suits your project- battery, small AC supply or rechargeable pack. Furthermore, I promise you(with flawless craftsmanship) the prototype will undergo thorough bench testing -- providing resistance, current draw details besides pull force analysis at the chosen voltage. Safeguarding of this prototype remains paramount, and you can trust that I will ensure rigorous and sufficient packaging safeguards for it during shipment.

I have completed similar electromechanical design and prototyping work, and I can support the development of your three compact electromagnets through physical fabrication, assembly and bench testing. With 10+ years of experience in mechanical CAD, electrical design and engineering prototyping, I can work from your winding diagrams and wiring schematic to plan the coil construction, insulation, terminations and mounting harness. Proposed Approach Review the winding diagrams, wire gauges, coil counts and electrical specifications. Confirm the core and harness materials based on the required dimensions and operating conditions. Fabricate and wind three electromagnets to the supplied specifications. Assemble the harness and integrate the required electrical connections. Bench-test resistance, current draw and pull force at the agreed voltage. Document the build with photos or a short operation video before shipment. Deliverables You receive three assembled, insulated and terminated electromagnets, a matching fabricated mounting harness, basic bench-test results, build photos or video, and securely packaged components prepared for shipment. Material and component costs can be documented with receipts for reimbursement, as agreed. I can begin by reviewing your drawings and performance targets, then confirm the fabrication method, workshop requirements, prototype cost and shipping timeline. Any electrical or thermal safety limits will be checked before testing.

Hi, Bojan here, from Serbia. Building your small electromagnet prototype with three compact electromagnets and 10 cm comes down to one thing: a board that works on the first order and can be built at scale. I'm a senior embedded and electronics engineer with 8+ years of experience working with Electronics, Mechanical Engineering and Electrical Engineering. For your small electromagnet prototype, the real challenge is part availability and manufacturability. A common issue: no DFM check before ordering, so boards come back with assembly or clearance problems. My plan: first, review the schematic, parts and enclosure limits. Then, update the layout with DFM, power paths and grounding in mind. Finally, run DRC and a DFM check, then prepare Gerbers and the BOM. The price is in the bid details. I've done PCB work before. A few questions to better understand the scope: 1. Does the board need to pass EMC testing? Then grounding and stackup get planned for EMC. 2. Add test points for the key signals? I'd recommend it, debugging and testing get faster. 3. Is the first batch a small pilot run? Run size decides which parts make sense. I can start right away. Happy to go over the details here in chat and suggest the best approach. Looking forward to hearing from you, Bojan
