I need a single 3-D printed prototype of my games controller so I can show investors what the finished product will look like. At this stage it is purely for aesthetic presentation, not for play-testing or electronics, so a clean exterior silhouette matters more than internal strength or moving parts. The job in a nutshell • Print the basic outer shell exactly to my STL (or convert my STEP file if that is easier on your end). • No hinges, buttons, or mechanical pieces are required—just the overall form factor. • Surface finish should be smooth enough for photos and light hand-held demos; light sanding or primer is welcome if it helps presentation quality. • I’m flexible on material; PLA, ABS, PETG or any other filament you trust for a neat su...

I need a detailed MATLAB/Simulink model that shows how a Level 3 DC fast-charging station behaves when a passenger-car battery is pushed for maximum charging speed, and how that strategy ripples back through the local grid.

I need a clean, manufacturable sheet-metal enclosure for an electronics device. I’ll give you the exact overall dimensions and all critical internal clearances; your task is to turn those numbers into a production-ready design. Key points you must incorporate: • Ventilation holes positioned to keep internal components within their thermal limits. • Integrated mounting brackets so the finished housing can be fixed directly to our panel. Please model the enclosure with standard sheet-metal practices in mind—correct bend radii, reliefs, and flat-pattern development—so the files drop straight into laser-cut and press-brake workflows. I prefer native SolidWorks or STEP outputs, along with a PDF drawing that calls out material, thickness, and tolerances. T...

Hardware Prototyping: GSM-Controlled Motorized Smart Lock (Custom Design) Project Description: I am looking for an experienced Electronics/Hardware Engineer to develop a functional prototype of a custom GSM-based smart lock designed for farmhouse and agricultural security.

An AI-powered workflow should turn raw specification sheets, model numbers, and feature lists into polished, formal product descriptions ready for our online electronics catalog. The tone has to be professional and trust-building, free of marketing fluff yet detailed enough for savvy shoppers comparing technical features. I will supply a CSV or JSON feed containing product name, key specs, dimensions, and any unique selling points. Your job is to design, configure, and document an automated process—leveraging GPT-4, Claude, or a comparable large-language model—to transform that data into publication-ready copy. The system must handle batches of products at once, keep factual details intact, and allow easy prompts or templates should we decide to adjust voice or structur...

...front, a short voice message I have recorded should play through an internal speaker. I would like the device to let me change that message whenever I wish—ideally by holding a record button or by uploading a small audio file—so I can cycle between holiday greetings, personalised welcomes, or even funny reminders. Because the trigger is just a standard, hard-wired bell button, please keep the electronics compact enough to mount near the chime transformer. Low-voltage power from the existing doorbell circuit is available, but I am open to adding a small DC adaptor if that simplifies things or gives cleaner audio. What I need from you • A working prototype that plays a clear, custom voice recording on each press • An easy method for me to re-record o...
