I help people turn ideas into real working products, from early concept to prototype and manufacturing-ready files. My work covers both the electronics side and the mechanical side, so I can help when a product needs a PCB, enclosure, structure, wiring, assembly design, or full product development. I like working on practical designs that are easy to build, easy to test, and ready for real use. On the electronics side, I can help with: * PCB design and layout * Schematic design * Circuit review and troubleshooting * Power supply circuits * Sensor and control circuits * Microcontroller-based systems * Wiring diagrams * BOM preparation * Gerber files and manufacturing files On the mechanical side, I can help with: * 3D CAD design * Product enclosure design * Mechanical parts and assemblies * Sheet metal or plastic part design * Prototype design * Design for manufacturing * 2D technical drawings * Assembly drawings * Mechanical improvements for existing products I can also help review an existing design and find problems before manufacturing. Many small issues in PCB layout, enclosure clearance, mounting holes, wiring, heat, or assembly can become expensive later. I try to catch those problems early and keep the design simple and reliable. My usual goal is not just to make something look good on screen. I focus on whether the product can actually be made, assembled, tested, and used properly. I care about clear communication, clean files, and practical engineering decisions. I can support you with: * New product development * Prototype improvement * PCB and enclosure matching * CAD model changes * Manufacturing file preparation * Product redesign * Technical drawings * Engineering consultation I’m comfortable working with clients who have only a rough idea, a sketch, an old design, or a product that needs fixing. You can explain the problem in simple words, and I’ll help turn it into a clear engineering plan. Before starting, I usually like to understand: * What the product should do * How it will be used * Size or space limits * Power requirements * Manufacturing method * Any current problem in the design This helps me give better suggestions and avoid unnecessary work. If you need someone who can think about both electronics and mechanical design together, I’d be happy to help. menos
