ABOUT THE PRODUCT The product is the EduFlex Aqua school headphone: Article 8718591953422. Look at this page first. EduFlex makes extremely durable headphones for schools. They are sold in 6-packs and used daily by children in primary education, as shared class sets stored on wall racks or trolleys. This is why we need a name tag: a set of identical headphones must be matched to pupils, classes or device numbers. The headphone is NOT a toy. It is a professional audio product for educational use in primary education. The design language is simple, robust and timeless - not childish, not trendy. The most important thing you must understand before you start: *** THE HEADPHONE BODY IS MADE FROM A SINGLE PIECE OF FLEXIBLE BIO EVA FOAM. It is soft, it bends, it compresses and it springs ba...

I am looking for an experienced Mechanical / Mechatronics / Product Development Engineer to perform an independent engineering feasibility audit of a compact device that combines controlled low-temperature drying and subsequent fine grinding of tablets or similar safe test materials. This is not simply a CAD, rendering, or industrial-design project. I already have several preliminary concept designs, but I do not want an engineer to simply convert them into CAD or confirm that they “look possible.” I need someone who can critically evaluate the physics, mechanics, airflow, heating, grinding, powder handling, cleanability, safety, manufacturability, and cost. If my current concept is too complicated, expensive, unreliable, difficult to clean, or mechanically incorrect, I wan...

I’m preparing the next growth phase for my company and have decided to concentrate resources on product development—specifically the design and prototyping stage of a new offering that’s now at concept level. I need a clear, actionable plan that tells me exactly how to move from sketches and rough ideas to a validated prototype we can present to investors and early customers. What I’m looking for • A concise roadmap that breaks the design-to-prototype journey into realistic milestones, including recommended tools or platforms (e.g., SolidWorks, Figma, 3D printing services) and the typical timelines and costs attached to each step. • Guidance on material choices, manufacturability considerations, and how to structure an iteration loop for user feedback...

The existing PCB is functionally sound, but several components need to be swapped for newer equivalents and a handful of additional SMD parts must be integrated without altering the overall board footprint. The layout will stay largely intact; the job is focused on component-level edits rather than a full redesign. Key work: • Replace specified components with the updated parts listed in my BOM draft. • Add two new SMD devices (a low-profile DC-DC converter and a temperature sensor) into the current schematic and layout, observing clearance and impedance rules already in place. • Update the BOM, pick-and-place, and assembly drawings so everything aligns with these changes. Deliverables: • Revised schematic and PCB layout files (Altium Designer preferred, KiCad a...
