I need a hardware designer who can take my concept for a compact “heartbeat” monitor and turn it into a fully-tested PCB that I can drop straight into network control boxes. The unit must run on a 12 V supply, use an ESP32 or similar, and expose a standard Ethernet port. Once powered, it should sense the input voltage, confirm link integrity, and—on a watchdog timer—send a small JSON payload via HTTP POST to my web server. I’ll handle all firmware in C++; what I’m after is the electronics and the board itself. Key points • 12 V input with on-board regulation suitable for the ESP32 • Reliable standard-speed Ethernet (no PoE needed) • Voltage and link-status monitoring lines broken out for code access • Footprint kept as small ...
I need a compact-footprint PCB that runs on a solid 12 V input and plugs straight into Ethernet so it can sit inside my equipment rack and let the rest of my system know everything is still alive. The board’s sole job is to send a small heartbeat packet at set intervals and, if the link ever drops, push an immediate network-status alert that my database can log. Remote-monitoring bells and whistles are not required right now; reliable data transmission and clear link reporting are the priorities. You can choose the silicon you are most comfortable with—an MCU with an integrated MAC/PHY, an external PHY hanging off an ESP32, or another combination—so long as it boots quickly, keeps the BOM lean, and exposes a straightforward way for me to adjust the heartbeat interval lat...
We are building SmartPTI™ Pro — a patent-pending, AI-powered commercial vehicle safety monitoring and predictive maintenance device developed under the TruckerGuard AI™ brand. It is designed for Class 7 and Class 8 commercial trucks operating under FMCSA regulations. SmartPTI™ Pro is not just a pre-trip inspection tool. It is a data-driven AI system that learns each vehicle's patterns over time and predicts mechanical failures, tire degradation, brake wear, and electrical faults before they happen on the road. This transforms it from a one-time checker into a continuous safety intelligence platform for fleets and owner-operators. This is a patent-protected, funded product with direct fleet industry backing from someone working inside commercial vehicle sa...
I am developing an industrial-grade board and need an experienced designer who works comfortably inside Siemens PADS. The job centers on a tight, multi-layer layout that hosts both microcontrollers and several power-management ICs, so clean power planes, controlled impedance traces, and rock-solid grounding techniques are critical. Here’s what I expect from you: • Capture the schematic (or import mine) and translate it into a manufacturable PADS layout. • Route every layer with proper clearances, via strategy, and DRC compliance. • Deliver complete Gerbers, drill files, BOM, and the native PADS project so I can iterate internally if needed. I’ll provide component datasheets, existing schematics, and mechanical constraints as soon as we start. If you have a ...
This task is for generating a KiCad v10.0 schematic from a given PDF. And if someone wants to also generate the pcb layout for it is welcome but the budget is very tight. There is an unfinished KiCad project that has the parts in schematic though the schematic has no connections, just the parts, also their footprints are/do exist in a pcb layout but without traces connecting them. I would like to have also the complete pcb layout generated but I want to keep the cost for now really low so I can accept just the schematic work. If someone though wants to bid for both schematic and layout then I could consider if the bid suits my budget. Please specify in your bid if it is for schematic only or for layout too. The schematic has FPGA/ADC/DAC/CODEC/CLOCK/POWER/etc spread in 12 pages, whoever w...

I’m ready to move a new consumer-electronics wearable from concept to production and need an experienced PCB designer who can take charge of a compact, multi-layer board. The board must seamlessly combine robust power management, reliable wireless communication (Bluetooth / BLE is preferred), and precise sensor integration for motion and biometric data. You’ll start from my preliminary schematic notes and block diagram, refine the circuitry for a 4–6-layer stack-up, and optimise the layout for low power, tight space, and signal integrity. Please keep antenna placement and ground-plane strategy top of mind so the wireless link stays clean even inside a small wearable enclosure. I’m comfortable with Altium Designer, KiCad, or Eagle files—choose whichever tool...
I need complete Gerber files for a multi-layer printed circuit board that will be built on six layers. The schematic is ready; what I’m missing is a clean, production-ready Gerber package that a board house can use without further tweaks. Here’s what I expect: • Layer stack-up defined and documented • Drill files, solder mask, paste mask, silkscreen, and assembly drawings included • All outputs checked against standard DRC rules and CAM verified before hand-off If you normally work in OrCAD, or similar professional tools, that’s perfect—just let me know which platform you prefer so I can provide compatible source files. Turnaround time and any questions about the stack-up or manufacturing constraints are open for discussion; I’m look...
I’m building FoodEase, an automatic cooking appliance that runs on a dual-core ESP32. The project is already architected around native ESP-IDF and FreeRTOS, so I need someone who can jump straight into low-level work—no Arduino abstractions—while still writing clean, production-ready code. Here’s what the firmware must do today: handle precise motor control and thermal regulation, collect and analyse data from temperature sensors, and maintain rock-solid Wi-Fi/BLE connectivity with a fully recoverable OTA update path. All of this has to coexist smoothly under FreeRTOS, so tight task scheduling, queues, semaphores and event groups are second nature to you. You’ll be driving PWM channels for the motor, talking to temperature probes over I²C, and keeping...
I want to develop a LabVIEW VI that integrates and synchronizes data from two sources: an Arduino-controlled actuator and a DAQ-based voltage measurement system. The Arduino is responsible for controlling the motion of a stepper motor and continuously outputs position data over serial communication. Specifically, it transmits time and position in a comma-separated format as “time_ms, position_mm” at approximately 50 millisecond intervals. This output has already been verified to function correctly using the Arduino Serial Plotter which I wrote the code for. Also, a DAQ system within LabVIEW is used to measure the analog voltage output from a load cell. This voltage represents the sensor signal and does not need to be converted to force at this stage. The DAQ portion of the sys...

I want an HID Omnikey 3021 smart-card reader—converted so it connects through a standard USB-C port instead of USB-A, while still providing full-speed data communication and bus power. I only need the cable/connector side removed and replaced with a USB-C connector so the device enumerates and draws power over USB-C just as reliably as it does over USB-A. There should be no cable, just a USB-C connector so that the device is as small as possible. Here is what will make the job a success: • The finished reader plugs into any standard USB-C host and both powers up and transfers smart-card data without errors. • All USB-C wiring follows the spec’s pin-out and current-handling guidelines. • You supply clear documentation (schematic or wiring map, parts used and...

My current firmware for the PIC18F46K22 already drives a 128 × 64 graphical LCD and a 4 × 5 keypad without issues, yet I now need to extend its functionality: two additional real-time parameters must be calculated and shown on designated areas of the screen. The existing project is written in C, built under MPLAB X with the XC8 compiler. Your task is to: • add the new variables to the main control loop, • update or create the drawing routine so these values appear neatly in the reserved zones of the display (font, coordinates and visibility must match the style of the current UI), • adjust any supporting timers, buffers or ISR code so that refresh rates and memory usage remain within device limits, and • return clean, well-commented source files th...
I want a bootable .img image for the Raspberry Pi 4 that turns the board into a fully offline, hardware-style wallet. After flashing the image to an SD card and powering up, I expect a clean graphical interface that lets me: • Generate and manage addresses for roughly forty of the most-used coins and tokens. • Sign and later broadcast transactions only when I briefly connect the Pi to a network. • Move funds straight to a linked bank account by entering a routing and account number—ACH style—without ever needing a third-party exchange. The build has to run reliably with no internet dependency at first boot, keeping all keys on the device and encrypted at rest. A simple on-screen flow for first-time setup, balance overview, and transfers is essential; I shou...
I need a single .img file that I can flash straight to a micro-SD, slot into a Raspberry Pi 4, power on, and start mining—no extra setup, no internet connection, just plug-and-play. The image must boot directly into an advanced graphical interface that lets me monitor hashrate, temperature, accepted shares, pool status, and switch coins without touching the command line. A high speed plug & play offline crypto miner for all 40 crypto currencies. The core requirement is support for the three main algorithms I selected—SHA-256, Ethash, and Cryptonight—so the device can tackle my full portfolio of roughly forty coins. Performance matters: the system should auto-detect optimal overclock settings for the Pi 4, make efficient use of its GPUs/CPUs, and offer pool configura...
I’m enhancing an Oracle E-Business Suite environment and need a custom OAF page that does three things in a single, streamlined flow. When the user opens the page, a report (already generated as PDF) must appear directly inside the page through an embedded viewer—no pop-ups, no forced downloads. After reviewing the document the user will place a handwritten signature on a Wacom device. I am not tying this to DocuSign, Adobe Sign, or HelloSign; the signature should be captured straight from the Wacom tablet using its SDK or another reliable method your propose, then burned into the PDF. Once signed, the same page should immediately save the updated PDF back into EBS as an attachment (BLOB) so it is viewable from the standard Attachments form. The file format remains PDF from s...

I need a complete engineering solution for an ultra-low-frequency electromagnetic transmitter that operates at roughly 22 Hz and fits inside an inline pipeline PIG. Once the PIG is in service, the beacon’s field must be strong enough to be detected up 3–5 m above the pipe, even when the signal has to pass through steel wall, backfill, soil, and asphalt or reinforced concrete. All operations take place underground and fully enclosed by steel, so coil geometry, core selection, drive strategy, and noise rejection are critical. Scope of Work: • Design a low-frequency (~15–30 Hz, target 22 Hz) EM transmitter • Optimize signal strength for underground detection • Develop efficient antenna/coil design suitable for pipeline use • Design low-power circuitry fo...

I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...
I’ve thought of a product that springs to life at the tap of a phone or web button, and I need a talented maker to turn that idea into a fully functioning prototype. The core is a pop-up mechanism—whether you favor solenoids, springs, or a tiny geared motor, I’m open—as long as it rises smoothly, reliably, and safely. Control will come from a Raspberry Pi or Arduino (again, whichever you feel best suits the task), with clean wiring and firmware that listens for a remote trigger. Alongside the hardware, I’ll need a very lightweight app or web page that exposes a simple trigger; bonus points if you can add basic status feedback without over-engineering. I’m happy to supply sketches and dimensions. To keep the conversation focused, please share: • P...
