I refer to the core objective of this assignment simply as “Farhan.” The name is a placeholder for an idea that still needs to be shaped into a tangible product, and I want to move quickly from vision to a working proof of concept. Here’s how I see the collaboration unfolding: first, we jump on a discovery call where I walk you through everything I have so far—goals, rough sketches, and any research I’ve gathered. From that conversation you translate the “Farhan” vision into a concrete plan, recommend the most suitable tech stack, and outline clear milestones. Once we lock scope, we move straight into building the first iteration, testing it together, and refining until the agreed-upon functionality is rock-solid. Deliverables • Writte...

I have a concept for a small control board that will act purely as a communication interface; the brain must be a microcontroller and every line on the board will ultimately speak SPI. I need the complete journey covered—from schematic capture through to a working prototype—and a simple companion application that can configure, send, and read data over that SPI bus. Hardware I want you to select an appropriate MCU, lay out the PCB, generate the BOM, and produce production-ready Gerbers. The board will only need the essentials: power regulation, the MCU, an SPI header, and whatever discretes are required for reliable signalling. Options such as UART or I²C might be added in a later revision, so leave enough pins and routing headroom for that future expansion. Firmware ...

I’m looking to build a long-term collaboration with a seasoned Figma specialist who can take full ownership of website design work. Typical assignments will involve turning my rough briefs or wireframes into polished, developer-ready Figma files, complete with component libraries, responsive layouts, and clear hand-off notes.

You should be comfortable working in iterative sprints: I share feedback daily, expect quick turnarounds, and like seeing clickable prototypes before we lock final visuals. Deliverables I’ll request on each task: • Source Figma file with well-n...

I’m building a tiny monitoring node around an ATTiny85 that has only four external components: a single LED, an NTC thermistor, a Hall-effect sensor and a piezo buzzer. I need clean, memory-efficient Arduino-style C/C++ code that: • Samples the thermistor, converts the reading to temperature and classifies it into three adjustable ranges. • Drives the lone LED so the user can tell at a glance which range we’re in (for instance OFF below the first threshold, slow blink in the middle, fast blink above the second threshold—but I’m open to any pattern that is easy to recognise). • Activates the buzzer whenever the temperature crosses the high-temperature limit and keeps it on until the reading falls back below that limit. • Reads and debounces...

I have a machinery component that needs to move from concept to a build-ready state in SolidWorks.
