Firmware Development Jobs

I need a business-grade projector purpose-built for classrooms that lets teachers and students interact directly with the projected image. The core requirement is an integrated interactive touch-screen capability—think smooth, low-latency annotation right on the board—paired with the brightness and reliability expected from a presentation unit. Here’s what I’m after: • Hardware: a projection engine bright enough for well-lit rooms, plus the touch-enabled overlay or sensor array that will register multiple fingers or a stylus without calibration headaches. • Software: driver package or embedded firmware so the touch layer appears as a standard HID device to Windows, macOS, and ChromeOS. Annotation tools or whiteboard software hooks are a bonus. •...

I am looking for an experienced embedded hardware and audio electronics engineer to replicate a custom automotive audio reverb/DSP module from scratch (0 to 100 delivery). The original circuit uses a Spin Semiconductor SPN1001-FV1 DSP, a Microchip MCP604 quad op-amp, and an external 8-pin EEPROM chip. I need a complete, end-to-end service: hardware reverse engineering, firmware dumping, PCB design, component sourcing, board assembly, and delivery of a fully functional prototype. Scope of Work & Deliverables: 1. EEPROM Firmware Extraction: Extract/dump the binary code from the 8-pin EEPROM chip on the provided reference board to preserve the custom reverb algorithm. 2. Schematic Capture & PCB Design: Recreate the schematic in EDA software (preferably KiCad or Altium) including the...

I have a consumer-electronics project that is almost ready for production, but I need a fresh set of expert eyes before I commit to tooling. Your job is to scrutinise every level of the design and give me a concise, actionable report. Scope of the review • Schematic – confirm AC isolation, creepage distances, relay selection and power-supply safety. • PCB layout – check placement, clearances, return paths and routing discipline. • BOM – verify component availability, footprints, part compatibility and RoHS compliance. • Firmware – validate logic for sensors, alarms, GSM SMS/call handling, relay control and fail-safe behaviour. • Safety & compliance – highlight anything that could jeopardise CE (LVD/EMC) readiness and fla...

Zephyr and LVGL developer: build 5 navigation models for a smartwatch OS We build MintWatch, a 454x454 round AMOLED watch running our own OS. The firmware is Zephyr with LVGL, written in C, and it builds today for native_sim on a desktop as well as for the watch silicon, so you can do this entire job on your own machine with no hardware. We need five new operating system models added to the existing set. What a model is here A model is not a theme. Our tree already separates the two, and this job is only the first half: Home: what is on the screen when the wearer is doing nothing. A watchface, an app grid, a conversation, a scrolling list of text. These are different devices, not different skins. Navigation: what every gesture does from home. Peers on a line, sheets over a home, cards in a...

I need an embedded developer who can write reliable, production-ready firmware that squeezes extra performance from aftermarket automotive modules. The immediate focus is on three devices: • CNG timing advancers • O2 optimizers • CKP sensors The end goal is measurable performance improvement, not just basic functionality, so timing accuracy, fast signal processing and rock-solid stability are essential. I am not certain whether any legacy code exists for these boards; you may be starting from a clean slate or refining half-finished firmware. Either way, I will supply the hardware, electrical schematics, and any reference data I can gather. You will advise on toolchains, microcontroller families and calibration workflows, then deliver: • Complete, compile-ready...

commissioning a run of 90 pairs of football shorts that quietly collect on-field data and turn it into clear, post-game insights for each player. The sole focus is performance tracking, specifically movement patterns and positioning; metrics such as sprint speed or heart-rate can wait for a later iteration. Here’s what I need from you: • Hardware & garment integration – lightweight IMUs/GPS or comparable motion-capture sensors sewn into the waistband or side panels without affecting comfort or washability. • Firmware & data capture – reliable logging of X-Y positioning and orientation throughout a 90-minute match, time-stamped for sync. • Cloud or local pipeline – automated off-load after the session (BLE or Wi-Fi is fine) into a databas...

I have an idea for a two-way text-messaging gadget that is no larger than a common correction-tape dispenser. The brain of the unit must be an ESP32-C3 and the only wireless link I need is Wi-Fi—no Bluetooth fallback. Power will come from a small, replaceable battery rather than USB or a rechargeable cell, so every milliamp you can save counts. Here is what I expect when we are done: • A compact PCB layout that fits the rough footprint of correction tape (around 95 × 25 × 15 mm; I can adjust a little if it helps with antenna clearance). • Complete schematic, Gerbers and a concise BOM with readily available parts. • Firmware built with ESP-IDF or Arduino-ESP32 that can send and receive short text payloads over Wi-Fi, display them (even a simple OLED/LE...

I’m developing a dedicated handheld that will operate offline. No Wi-Fi, Bluetooth, cellular, or any other radio is required, so the entire design has to function in isolation. Because of that restriction I’m open to whichever operating system keeps the footprint light and the boot time quick, whether that’s a stripped-down Android build with networking stacks removed or a fully custom OS. but more likely just on/off. then a button to run. Your task is to take the idea from concept to a working prototype. I’ll need the electronic design (schematic, PCB layout, and component selection), a daylight-readable display, a rechargeable battery able to power at least eight hours of continuous use.. Low power consumption, immediate on/off and rock-solid stability. Delivera...

I need a compact firmware-and-hardware solution that lets a PIC microcontroller, programmed with the XC8 compiler, manage a battery-powered power supply built around a lead-acid pack. Here is what I am after: the PIC should start up from the battery, regulate or switch the output rails as required, continuously read the pack voltage, temperature or any other basic health indicators, and trigger clear actions (for example, low-voltage cutoff or status signalling) before the battery reaches critical limits. A simple serial, I²C or even LED indicator scheme is fine for status feedback—as long as I can read the key parameters easily during bench tests. Please base the code on MPLAB X + XC8 so I can compile and tweak it locally. If you prefer a specific mid-range PIC that is re...

I need a specialist to build the core firmware. The brain of the machine is an STM32 MCU and it must coordinate three key subsystems—motors, heaters, and fans—through a pair of Trinamic drivers (TMC2209 and TMC5160). Your code will run in Embedded C/C++, parse incoming G-code, and translate it into smooth motion and reliable temperature control while guarding against every fault scenario a printer can face. Here is the scope in practical terms: • Motion: drive multiple stepper axes with proper acceleration/deceleration, junction deviation, and micro-stepping using the two Trinamic driver families. • Temperature: read NTC thermistors, run a well-tuned PID loop for hotend and bed, manage cooling fans, and shut everything down on thermal runaway. • Safety &...

I’m wrapping up the hardware side of a 3.5 kW single-phase on-grid inverter I’m building for my own use and now need well-structured C firmware to bring it to life. The goal is solid, standards-minded code that will: • keep the inverter phase-locked to the utility grid (grid synchronization), • sample and report key electrical parameters in real time (power monitoring), and • trigger a fast, orderly shutdown whenever limits are exceeded or the grid disappears (safety shutdown). I will share the full microcontroller pin-map, schematic details, and any manufacturer SDKs I already have. You’re free to work with bare-metal C or leverage vendor libraries as long as the final build remains portable and easy for me to maintain. Clear comments, interrupt-...

I’m putting together a compact dual-camera dashcam that can watch the road and simultaneously monitor the driver. I already have the product vision and feature set defined; now I need an embedded systems specialist who can turn it into working hardware and firmware. Core functionality • Two SD-resolution image sensors, one road-facing and one cabin-facing • Live video uplink over 4G/LTE plus on-device recording to a removable SD card • GPS receiver for continuous tracking and metadata stamping • Integrated motion sensing and true impact detection, so an on-board accelerometer must trigger and flag critical events even when the car is parked • Clean vehicle-grade power input and automatic power-down logic to protect the battery Scope of work 1. Com...

I’m building a small consumer-electronics project and need a purpose-built, rectangular PCB that can drive an induction heater at up to 100 W. The board must accept power from either a standard DC adapter or a USB-C PD or DC source, automatically negotiating or routing whichever is connected. Power control is intentionally simple: ten individual LEDs indicate output in 10 W increments (10 W – 100 W), and a single rotary dial steps the power up or down in those same 10 W stages. No screen, menus, or extras—just clean, reliable hardware. What I expect from you • Complete schematic with component values, coil connection, gate-drive stage, protection (over-current / over-temp), and USB-C PD or DC supply trigger circuitry. • PCB layout ready for fabrication...

I need a compact, indoor-only training device that keeps my dog or cat within designated areas. The goal is simple behavior correction for containment, not trick teaching or general exercise. When a pet approaches or crosses a virtual or physical boundary, the unit should deliver a very mild shock stimulation—strong enough to deter, yet well within accepted animal-safety standards. Here is what I’m looking for: • A complete concept and schematic for the device, including sensor choice, power requirements, safety circuitry, and enclosure design. • Firmware or control logic that triggers the mild stimulus reliably and only when intended. • A brief user-setup guide so anyone can define or adjust boundaries indoors. If you can add optional sound or light cues ...

I want a self-contained GPS tracker that snaps magnetically onto a car’s chassis and keeps reporting its real-time location without relying on any phone app or cloud dashboard. All positioning data should come straight from the device itself—either displayed on a small built-in screen, spoken through a buzzer/voice prompt, or transmitted by SMS/GPRS so I can query its whereabouts on demand. Key points I need covered: • Stand-alone operation – no external app or web portal required • Strong magnetic mount suitable for everyday cars, remaining secure at highway speeds and through rain, heat, and light off-road vibration • Accurate GPS/GLONASS reception with frequent, user-configurable update intervals • Long-life rechargeable or replaceable ba...

I have a new electronic concept that now needs to move from idea to a working prototype, and I want it laid out in Autodesk EAGLE. Your task is to design a prototype-ready PCB that brings together three key blocks: a microcontroller core, several on-board sensors, and a stable power-supply section. I will provide the preliminary schematic notes and the part shortlist; you handle the full schematic capture, board layout, DRC/ERC checks and the usual clean-up so the files are manufacturing-ready. Please keep the board footprint compact and component placement serviceable for hand-assembly during the first test run. Deliverables I expect • .sch and .brd files from Eagle • Gerber and drill set zipped for the fab house • A concise BOM with manufacturer part numbers &b...
