I have the full schematic for working legacy PCB. I need it redesigned and modernised into a new board using current components, while keeping the original board size, mounting holes and connector positions. The old design uses PIC18F8722, FT232RL, TDA7465, video switching and RCA outputs. The new design should replace those with STM32 native USB, modern audio DSP/codec, protected coin inputs, modern power regulation, and custom firmware support. This is not an exact clone. It is a modern drop-in replacement using the original schematics as a reference. Key things :- Keep: * Board size: 168mm × 206mm * 6 mounting holes * USB-B position * Existing amp connectors * Mic input * Coin mech interface * IR receiver/service button * J8 motherboard audio input Remove: * RCA sockets * Vi...

I have a small home-automation module that needs a reliable touch interface, so the task is to engineer a 5 V circuit around the TTP223 that cleanly switches between high and low digital levels whenever it is touched. Precision in sensitivity and long-term stability matter more to me than squeezing out the very last microamp, yet the design should still sit comfortably in standby without wasting power. Key expectations • The sensor must tolerate normal household electrical noise without false triggering. • Output logic levels must be directly MCU-friendly (TTL/CMOS, active-high preferred). • Component count should stay minimal; surface-mount parts are fine. • Any necessary debounce or filtering should happen in hardware rather than firmware. Deliverables 1. ...

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. The role is purely website focused—think landing pages, multi-page marketing sites, and occasional micro-interactions—so a strong eye for hierarchy, typography and grid systems is essential. 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. I will share overall dimensions, functional requirements, and the space envelope; from there, I need you to generate a clean 3D model, create fully toleranced drawings, and flag any manufacturability concerns. Once the CAD package is final, I also want guidance on a physical prototype—material selection, off-the-shelf hardware to source, and simple jig or fixture ideas that will let me verify fit and function in the shop. Please highlight projects where you have taken a mechanical part all the way through SolidWorks modelling, drawing release, and into a first-article prototype; those real-world results matter more to me than theoretical designs. Familiarity with common machine-shop pr...
