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.

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

I will build and bench-test three compact electromagnets into working proof-of-concept units exactly from your winding diagrams, coil counts, wire gauges, and full wiring schematic. This is hands-on prototyping: I’ll physically wind, insulate, terminate, and assemble each magnet under 10 cm in every direction, then fabricate a matching custom harness to precise mounting dimensions so the set can be installed as intended. I’m ready to recommend the best light alloy/metal approach after reviewing your constraints and tolerances. I’ll reimburse all materials, fasteners, and electronic parts at cost with receipts. Power setup (battery pack, small AC, or rechargeable) will be selected to match your workshop reality and the performance targets we agree on; I’ll instrument resistance, current draw, and pull force at the chosen voltage, then capture photos or a short video showing operation before shipment. Secure, protective packaging will be used for delivery.

Hands-on prototyping is increasingly the fastest path from schematic to measurable performance—especially for compact electromagnets where tolerances, insulation, and harness fit determine results. For Project 872, I will convert your provided winding diagrams, coil counts, wire gauges, and full wiring schematic into three fully wound, insulated, terminated electromagnets (each <10 cm in any dimension), then build the matching custom harness to precise mount dimensions for your proof-of-concept. You’ll receive a disciplined workflow: hand-assembly, continuity/insulation checks, termination verification, and bench testing at the agreed voltage (resistance, current draw, and pull force). I can recommend a light alloy or alternative metal after reviewing your constraints and fit/thermal expectations. All parts and raw materials are reimbursed at cost with receipts.

I’ve previously taken tightly specified winding diagrams and converted them into working prototypes with measurable bench data—building the coils, insulating and terminating leads, fabricating the mechanical fit, then validating resistance/current and force before shipment. Here, I’ll do the same for three compact electromagnets (each <10 cm in any direction) using your provided counts, wire gauges, and full wiring schematic, with hands-on assembly and testing only—no design-only deliverables. I’ll build three fully wound, insulated, terminated electromagnets and fabricate a matching harness to precise dimensions for your custom mounting. I can recommend the best metal/light-alloy housing based on constraints once I review fit, cooling, and mounting; all raw materials, fasteners, and electronic components will be reimbursed at cost with receipts.
