Prototipare Jobs

I’m ready to move from vague inspiration to a concrete plan for a new product or service, and I’d like a skilled partner to guide that journey. The only firm direction so far is that we’re creating something new; whether it ultimately becomes a web platform, a mobile experience, or even a physical solution is still wide open. I’m deliberately keeping the brief flexible so your research, creative thinking, and technical insight can shape the best path forward. Here’s what I need from you: • A concise discovery phase that captures the core problem, target audience, and competitive landscape (desk research, lean market analysis, or customer interviews—whatever you know works). • A validated concept document outlining key features, user flows,...

I’ve already sketched and modelled a sleek, pen-sized instrument that fuses four everyday essentials for medical-device reps: a fine-tip pen, a permanent marker, a rechargeable laser pointer, and a concealed, auto-retracting ceramic blade for opening cartons. Now I need to see it come to life in the form of one or two fully working prototypes that prove every feature actually functions. Functionality and quality are my top priorities. The prototypes have to write cleanly, shine a steady laser, and retract the blade the instant pressure is released. To make that viable all day, battery life and a convenient USB-C (or similarly compact) charging solution are non-negotiable. Safety is equally critical: the laser must include recessed button for activation, and the ceramic blade mechani...

I’m putting together a dedicated, distraction-free reading device and need a hardware specialist who can take it from concept to working prototype. The display has to be an AMOLED panel of at least 11 inches—no compromises on that vibrant contrast. This will be a reading-only tablet, so efficiency, eye comfort, and battery life have priority over raw processing power. Wireless connectivity is essential for loading books and updates; Wi-Fi is mandatory, Bluetooth is optional. In addition, I want physical page-turn buttons on the bezel so users can flip pages without touching the screen. Touch input itself is welcome but not a requirement. Here’s what I’m expecting from you: • Source and validate the 11″+ AMOLED display and its driver board • Desi...

I am developing a custom mechanical wristwatch with a unique interactive feature: The upper part of the watch (bezel + glass + dial) can spin manually like a spinner. The lower case and watch hands are fixed. Spinning is locked by default. When the user pulls the upper part upward (lift trigger), the lock is released and the upper part can spin. When the user pushes it back down, spinning is locked again. This is a purely mechanical system (no motor, no spring-driven spin, no electronics). The goal of this project is to design the mechanism, produce engineering drawings, and prepare manufacturing-ready documentation so I can prototype and mass-produce the watch in China. Core Functional Requirements (Must-Have) 1. Locking System Rotation is mechanically locked when the upper part ...

I need a complete visual overhaul of my Graphic Design-focused web application. The goal is to replace the current, dated interface with a clean, intuitive UI that feels modern and speeds up the creative flow for users. The application is an accounting software. You’ll be working on a web platform only—no mobile or desktop software versions—so every screen, component and interaction should be optimised for the browser, with responsiveness in mind for common breakpoints. Here’s what I’d like to receive: • High-fidelity mock-up for the one (!) of the attached screens • Source files in Figma ready for hand-off to developers • A short style-guide document describing your design decisions. Be aware, this is a contest to find a skilled graphi...

Ho bisogno di una scheda elettronica su misura che gestisca esclusivamente sensori di movimento installati all’interno di un espositore. L’applicazione è quindi indoor: vorrei un circuito compatto, a basso consumo e in grado di dialogare in modo stabile con i sensori IR/PIR (o tecnologia analoga, se più indicata). Oltre al dimensionamento elettrico, mi interessa che vengano previsti i connettori giusti per un cablaggio rapido dentro la struttura espositiva e che l’alimentazione sia compatibile con i 5-12 V già presenti nello stand. Non ho vincoli sul microcontrollore: va bene qualsiasi soluzione diffusa e facilmente reperibile, purché la programmazione sia semplice da aggiornare in caso di future modifiche logiche. Deliverable richiesti &bu...

Project Brief: Stealth-Modified Automatic Parking Disc (Certified for Public Road Use in Germany) Project Goal: I want to technically modify a certified electronic parking disc approved for use in Germany (must have an official certification number and ECE approval), so that it continues to automatically update the displayed parking time even after the vehicle has been parked. This modification must be invisible and undetectable from the outside, meaning the device must look and behave like the original product to any observer or parking enforcement officer. Background: Standard electronic parking discs are designed to detect when a vehicle is turned off and then freeze the display at the next permissible half-hour mark. This allows parking enforcement to determine how long the car has b...

I want to turn my stock WowWee MiP into a fully-independent companion with far more capability than the original phone-controlled toy. The big push is to give it functional robotic arms—servo-driven, proportional, and strong enough to perform simple pick-and-place demos—while keeping the self-balancing chassis intact. To drive everything, I need an internal “brain” (Raspberry Pi, ESP32, or another MCU you’re comfortable with) that can: • run onboard code without any phone connection • store multiple programs in flash so I can swap behaviors on the fly • process a forward-facing camera for navigation and object tracking • handle voice-command triggers and speak back in character using a small speaker For interaction I’m l...

My SaaS platform already runs smoothly on the web, and the backend endpoints are in place. Now I need the front-end translated into a genuinely native mobile experience, built for React Native on both iOS and Android. The core use-case you’ll be designing for is business analytics, presented through two perspectives: an Admin dashboard and a Barber view.

Deliverables I expect: • High-fidelity UI mock-ups (Figma or comparable) for every primary screen in both roles • A clickable prototype to demonstrate flow and micro-interactions • A compo...

I already have a handful of starter frames in Figma, but I now need a fully-fleshed, high-fidelity prototype that maps every nook and cranny of a micro-loan product—customer-facing and back-office alike. The final file must walk a user (and an auditor) forward and backward through every possible path: sign-up, eligibility check, document upload, loan application, status tracking, repayment management, and the inevitable “what-if” exception states. Customer support is integral, so please weave in real-time live chat, email escalation, and an in-app Help Center/FAQ across both mobile and web breakpoints. Each support touch-point should feel native to the flow rather than bolted on. Because this product will ultimately sit under FCA scrutiny, I’m only interested ...

I want to turn a clean, minimalist concept for a spectacle case into a ready-to-print 3D model. The case must hold standard-sized eyewear securely, but the real headline is style: a refined, pared-back shape that looks good on a desk yet slips easily into a bag or pocket. Material & finish I’m leaning toward a biodegradable filament, so please keep wall thicknesses, hinge ideas, and snap-fit details suitable for common PLA/PHA or similar eco-friendly blends.
