I’m building a small arcade-style attraction made up of six identical stations. Each station will recognise when its hand-held controller is lifted by means of a magnetic sensor—or any other proper kind of sensor —then launch a three-minute countdown. Here is the user flow I need you to realise: 1. Controller is lifted → internal timer starts. 2. An OLED screen at that station immediately shows the remaining time, counting down in real time. 3. When the three minutes expire the screen simply replaces the countdown with a clear “Game Over, move to next zone ” message + a buzzer or light; 4. Once the controller is set back the system must reset itself, ready for the next player. Hardware thoughts so far: magnetic (reed or Hall) sensor to detect li...

I need a start-to-finish Figma file for a Health & Fitness mobile app that lets users create a “love avatar,” track their well-being, and share progress with friends. The design should feel minimalist and clean while still supporting playful touches where avatars, badges, and an in-app shop appear. The prototype must cover every main flow—from first-time onboarding through daily check-ins, social interactions, and purchase screens—so that I can simply send a Figma link to investors, developers, or testers and they’ll see a seamless, clickable journey. Please be sure the final file includes: • Avatars and profiles • Social interactions (likes, comments, friend activity feed) • In-app purchase / shop features (coins, premium themes, av...

I need a double-layer, signal-processing board laid out in Altium Designer and prepared for fabrication at JLCPCB. The finished board will fit inside a 15 cm × 15 cm envelope, so component placement, routing, and keep-outs should respect that medium-size constraint. Deliverables I expect: • Complete Altium project with schematics and PCB layout • Optimised Gerber, drill, and pick-and-place files matched to JLCPCB’s specs • BOM with manufacturer part numbers and assembly notes I will review the design by importing the files directly into Altium and running JLCPCB’s online DFM check; the job is complete once the files upload without errors and the board passes ERC/DRC.

I need the internal circuitry of the KK-82MS scientific calculator documented so I can design a drop-in replacement PCB. Your job is to open the unit, trace every relevant signal, and give me a clear map of what connects where. The focus is on both LCD behaviour and the button-scanning scheme, so I expect you to show how each LCD segment is driven, which pins act as commons, how the microcontroller multiplexes them, and the exact keyboard matrix rows and columns the processor polls. Feel free to combine a logic analyser, multimeter, oscilloscope, or any other bench tool you trust; choice of instrumentation is up to you as long as the final data are unambiguous. Deliverables • High-resolution photos of the calculator fully disassembled, including close-ups of the flex cables and IC m...

I’m developing an IoT device that will live permanently outdoors, so the enclosure must be tough st and attractive. The product needs to be C1D2 certified. I have sketched the basic board layout and I now need a mechanical engineer who can carry the housing from an initial requirements definition all the way through to documentation for mass production. Durability drives every decision: weather-proof seals, UV-stable plastic (I’m leaning toward a robust polycarbonate or glass-filled nylon), impact resistance, and the ability to maintain watertight integrity after repeated assembly cycles. If you feel a metal insert or composite gasket improves reliability, I’m open to those suggestions, but the core body should remain plastic to keep tooling costs and weight down. The w...

I have an early concept for a multi-purpose woodturning tool and I need someone to turn that idea into a build-ready prototype. At this stage it is nothing more than sketches and functional notes, so your primary task is to translate the concept into detailed 3D CAD and engineering drawings I can hand straight to a machinist. Core functions • Cutting and shaping • Detailing and finishing • Hollowing out The finished design must handle both hardwoods and softwoods without swapping cutters mid-project, so balance, vibration control and edge durability are critical. I am open to carbide inserts, HSS, or a hybrid tip system if it meets those goals. Deliverables 1. Parametric 3D model (SolidWorks, Fusion 360 or similar) 2. Fully dimensioned drawings with tolerances...

I’m overhauling BeEasy, my wedding management & RSVP platform, and the first area I want you to tackle is the entire RSVP flow—from the guest’s first click all the way to the confirmation message and automated notifications. These screens currently feel dated; I need them re-imagined in Figma with a fresh, modern-and-trendy aesthetic that still reads “elegant wedding” rather than generic SaaS. You’ll have a free hand with colour and typography because I’m open to new suggestions; what matters most is a clean hierarchy, effortless navigation on mobile and desktop, and components that translate smoothly into a React + TypeScript codebase. Think practical interactions, clear states, and a layout grid that my developers can lift almost verbatim....

I need a replacement gear modeled for 3-D printing. It is the small plastic gear you usually find inside a CD player drive and has to mesh perfectly with the surrounding train, so dimensional accuracy is critical. The gear will ultimately be printed in plastic, so tooth profile, wall thickness, and fillets must all suit common desktop FDM or resin printers. What matters most to me is high precision: the finished part must drop straight into the mechanism with no extra sanding or shimming and run quietly. Please base the geometry on standard spur-gear calculations; if you spot a better geometry that still meets the CD-player layout, let me know before finalizing. Deliverables • Parametric CAD model (STEP or native SolidWorks / Fusion 360) • Print-ready STL file • A sh...

I’m looking for a like-minded designer to team up with me on a new design-led project. The collaboration is intentionally open-ended: I already have the concept sketched out, and I’d love to bounce ideas back and forth, refine the visual language together, and then move into production. The heart of the work is design, so expect plenty of mood-boarding, typography and colour exploration, and iterative prototyping in tools such as Adobe CC, Figma or whatever gives us the fastest creative feedback loop. If our chemistry is right, we can branch into adjacent content creation later, but the first milestone is a polished, ready-to-publish design solution we’re both proud to sign off on. You’ll bring solid visual craft, clear communication, and the confidence to cha...

I’m commissioning a life-size, wearable snake that drapes from my waist, coils up my torso, and settles its head on one shoulder. The body should be built from black faux fur or a soft plush, yet finished so the surface feels textured and scaly rather than smooth. Inside, I’ll need just enough internal support to keep the coils looking crisp while still allowing me to wrap and adjust the snake easily. A touch of weight—beans, pellets, or similar—will help it stay put on my shoulders without constant readjustment. The head is where realism matters most. I’d like glass or high-quality plastic eyes in a vivid red, set into a sculpted face with defined scales and sharp, pointed fangs. The mouth can be slightly open or closed; whichever better shows off the fangs ...
