I need a clean, well-commented Arduino sketch that drives a small traffic-light prototype using LEDs, push-buttons, and a couple of sensors (e.g., ultrasonic or IR) to regulate flow rather than just cycle through a fixed sequence. The idea is to simulate a real intersection where vehicle presence triggers state changes while manual override buttons allow testing of special conditions. Here’s what I expect: • The code must compile on the current Arduino IDE without extra libraries beyond the standard ones. • Normal operation: red, yellow, and green LEDs follow proper timing, but a vehicle-detection sensor shortens or extends green time to keep traffic moving smoothly. • A pedestrian button interrupts the flow safely, inserting a walk phase before resuming. &bul...

I need a clear, ready-to-build circuit diagram that closes the voltage feedback loop on the DC bus of an off-grid inverter running in the 12 V – 24 V range.

I have a completed audiophile phono-preamp in ExpressPCB+ — schematic and two-layer board — that I now need recreated in Fusion 360 Electronics. The circuit holds 33 unique parts (about 120 total) and follows a simple structure: one power-supply section repeated six times and two identical audio channels. Because of this repetition, copy-and-paste inside Fusion should accelerate the job. All manufacturer part numbers are ready to drop straight into the new library, so you will not have to hunt for footprints or symbols. Trace widths and clearances can remain at Fusion’s defaults; no additional design-rule tuning is required. We will also keep the layer count exactly the same as in the ExpressPCB+ file. Mechanical constraints are critical: • Overall board outline m...

I need my current water-level indicator rebuilt from the ground up so it does far more than just show a level. The new design must constantly monitor the tank, trigger automatic fill/stop routines, and run solely from a compact battery pack. I am open to whichever display technology you feel best suits the build—I mainly care that the read-out is clear, low-power, and robust enough for daily use. Scope of work From concept sketches to a working prototype, you will rethink the sensing method, control logic, power management, and housing. That includes choosing the ideal microcontroller, designing the PCB, writing the firmware, and packaging everything in an enclosure that can handle occasional splashes or condensation. The finished unit should be maintenance-friendly and easy for a n...

I’m developing a universal, plastic cap that slips onto the mouth of most squeeze-tubes and recovers up to 99 % of the product left inside. The design relies on a small piston housed in a vacuum chamber; a fingertip-sized button on top pulls air out, drawing the contents toward the nozzle so virtually nothing is wasted. Plastic is the chosen material because it keeps tooling costs down and supports high-volume injection molding, yet still lets us integrate the moving piston, seal, and one-way valve in a single part. I’d like your help turning the concept sketches into production-ready CAD, complete with tolerances, assembly notes, and bill of materials. SolidWorks, Fusion 360, or similar parametric software is ideal, as I’ll need native files plus STEP/IGES exports for m...

I have a reaction-timing system schematic that needs a careful second set of eyes. Your task is to validate the entire power section—specifically the voltage levels, current-carrying capability of each rail, and how the various power sources are integrated—and then scrutinise every ceramic capacitor on the board for correct capacitance values and voltage ratings. You’ll receive the full PDF and the original design files (KiCad). I expect clear, pin-referenced comments on the schematic plus a concise report outlining: • any mismatched voltage rails or trace width issues that could limit current • potential inrush or stability concerns tied to the chosen power sources • capacitors whose stated capacitance or voltage rating doesn’t align with the c...

I’m rebuilding our sales-driven web application from the ground up and need a seasoned UI/UX designer who can turn business goals into a high-converting user journey. The app’s sole purpose is to generate qualified leads and close sales, so every screen must guide visitors toward that outcome. You’ll start by assessing our current flows and data, then craft wireframes that streamline registration, product discovery, and the e-commerce checkout I have in mind. From there we’ll move into interactive prototypes—Figma or Adobe XD are both fine—to validate the experience before you polish the final visual language. Responsive behaviour is essential; most users land from mobile ads but finish their purchase on desktop, so consistency across breakpoints matter...

I need a simple visual prototype built to impress and inform my stakeholders. The goal is to let them click through the core screens, see the intended look and feel with colours, typography and basic interactions, and walk away confident about the direction of the product before we invest in full development. Scope • Medium-fidelity: more polished than wireframes but not pixel-perfect; think clean layouts, brand colours and a handful of key transitions. • Platform-agnostic: whether the screens are viewed in a browser, on mobile or desktop doesn’t matter—clarity of flow is what counts. • Stakeholder demo ready: the file should open instantly (Figma link, InVision, XD prototype, or another lightweight web-hosted format) with no extra setup. What I will provide &n...

I’m building a brand-new social platform whose core purpose is to help users form and nurture tight-knit communities.
