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. What I still need is a skilled electrical engineer who can turn that mechanical shell into a working MVP that we can put in front of early testers. 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 physically assembling one fully functional unit. A short test protocol verifying vibration ranges, surface temperature stability and basic safety is part of the assignment so we know the prototype is ready for user feedback. Deliverables 1. Finalised electrical schematic and BOM 2. Wiring layout clearly referenced to my STEP file 3. Assembled working prototype (1 unit) with vibration and heat fully operational 4. Test report confirming functionality and safety limits I’m happy to supply the mechanical parts and the components I’ve already sourced. Everything else—additional parts, PCB design if required, cabling, and assembly—falls within this project. If you’re confident with small electromechanical builds and have experience merging heat elements with vibration systems, let’s get this MVP built.

Hi I am an embedded systems engineer with over 16 years of experience in small electromechanical products, motor control, heating elements, safety wiring and prototype builds that have to fit inside real mechanical envelopes. I can take your STEP model and sourced parts, check the fit and electrical load paths, then turn the massage and heat functions into a working MVP rather than just a paper design. My approach would be to first review the CAD and your selected motor/heater parts for clearance, mounting, airflow/thermal paths and serviceability. From there I would finalize the power architecture, driver/control parts, wiring gauge, fusing, connectors and temperature limiting so the unit is practical for early user testing. I can provide the schematic, BOM, wiring layout referenced to the STEP file, assemble the prototype, and run a simple but useful test report covering vibration/pressure ranges, surface temperature stability and basic safety limits. I also have experience taking consumer-grade hardware from concept through prototype and production, so I can flag issues now that may become expensive later. Please contact me to discuss details.

Hi, This project aligns well with my experience in product development, embedded electronics, electromechanical systems, PCB design, and prototype manufacturing. I understand that you already have a completed STEP model and selected key components, and that the objective is to transform the existing mechanical design into a functional MVP with adjustable pressure and integrated heat therapy suitable for user testing. My approach would begin with reviewing the STEP model and selected components to verify mechanical fit, thermal considerations, wiring paths, and overall integration feasibility. Based on that review, I would develop the electrical architecture, select any missing supporting components, prepare the schematic and BOM, define the wiring layout, assemble the prototype, and validate both vibration and heating performance. I have more than 12 years of experience developing electronic products, automation systems, robotic equipment, and manufacturing-ready prototypes, including PCB design, power management, motor control, thermal systems, assembly, and testing. Before finalizing scope, I would like to clarify whether the MVP is expected to use commercially available motor/heating control modules for rapid development, or if a custom PCB solution is preferred. This will help define the most efficient and cost-effective approach. I would be happy to review the STEP model and selected components and discuss the best path to a reliable working prototype.

Greetings, I worked before on a small electromechanical test device where space was tight, and the main work was fitting a motor, driver, wiring, and sensor parts cleanly inside an existing housing. The important part was not only making it run, but making sure the heat, moving parts, wiring, and safety parts were stable enough for real users to try. For your foot massage MVP, I think the main challenge will be balancing motor pressure, heat control, and safe wiring inside the STEP envelope without making the inside too crowded. I would first review the CAD and your selected parts, then confirm fit, choose missing parts like motor driver, thermal cutoff, fuse, connectors, and wire gauge, then build one working unit. If the supplied parts are already close to final, I think a first bench demo can be ready in about 10–14 days, and the assembled MVP with a short test report in about 3–4 weeks. A few things I would need to check first are the motor specs, target heat temperature range, power source, and whether the unit must be battery powered or wall powered. Sincerely, Oleksandr

Hello, Primary risk is thermal coupling and space constraints inside your STEP CAD: fitting a compact motor system plus heating elements while maintaining safe surface temperature and serviceable wiring is the main technical challenge I will address first. I have 10+ years delivering electromechanical prototypes for consumer wellness and small medical devices, including motor-driven actuators with closed-loop speed and torque control and integrated heating with PID temperature control and redundant safety cutouts. Recent projects included designing schematics, selecting drivers, temperature controllers, fuses, connectors and producing a single assembled prototype with test protocol and report for vibration and surface temperature stability. I will start by importing your STEP file, perform a clearance and thermal analysis, then produce a finalized electrical schematic and BOM. My first concrete step is a detailed fit and thermal map inside the housing to determine motor placement, heater type, required insulation, and sensor locations. Deliverables will match your list: finalized electrical schematic and BOM, wiring layout referenced to the STEP file, one assembled working prototype with adjustable pressure and heat functions, and a test report covering vibration ranges, surface temperature stability, and basic safety limits. I will include recommended component part numbers and wiring gauges. - Do you have target vibration amplitude and frequency ranges or a reference device to match? - Are there envelope constraints for insulation thickness or maximum allowed surface temperature? Open to a quick chat if you want to dig into the details. Andrew
