I need an embedded-software specialist who can take my collection of Wi-Fi and LoRaWAN gateways and assorted sensors and knit them into a single, production-ready IoT platform. The job covers the full stack from firmware that runs on the edge devices through to the application layer that users will see. Core capabilities the platform must deliver: • Data collection from every gateway and sensor • Robust device management (on-boarding, remote configuration, OTA updates) • Built-in analytics so I can visualise trends and run simple rules without exporting data elsewhere You’ll be free to recommend languages, embedded RTOS options, and cloud back-ends, provided they reliably handle both Wi-Fi and LoRaWAN traffic and scale cleanly as more hardware is added. De...

I’m working with a Diode Laser Board and I need a custom receiver that can plug into that setup, track the machine’s positioning in real time, and instantly flag any faults it detects. The idea is to have continuous monitoring so I can see where the laser head is at any moment and receive automatic alerts if something drifts out of spec or a component misbehaves. Ideally, the receiver will take positioning data straight from the board, process it with minimal latency, and expose a simple interface—serial, USB, or another protocol you recommend—so the data can be displayed live on a host PC or microcontroller dashboard. Reliability is critical, so built-in error detection should cover signal integrity, unexpected motion, and any other obvious fault conditions you id...

AI-Controlled XYZ Writing Plotter + Camera System Project Goal I am looking for a developer to build a reliable, plug-and-play system that allows an AI/LLM running on a Windows PC to control an XYZ writing/drawing plotter and view a tablet through a camera.

Design and build a three-phase, 50 V / 30 A SPWM inverter tailored for an induction motor. The work spans the complete hardware chain—schematic capture, PCB layout, power stage assembly, and gate-drive/protection circuits—plus the firmware that drives it. Either a PIC32 or STM32 can sit at the core; choose whichever lets you deliver stable, low-jitter PWM with minimal dead-time distortion. Firmware targets • Closed-loop speed control with a user-selectable frequency range of 0–250 Hz • Parameter entry and live monitoring over UART, USB, or CAN (pick one to keep the bill of materials lean) • Safe-start, over-current, and over-temperature trips baked into the interrupt flow Deliverables 1. Complete schematics (Altium, KiCad, or other mainstream CAD)...

I want to introduce an IoT-driven inventory management system into my single-location car body shop so I can serve customers faster and with fewer stock-outs. The whole point is efficiency: when a repair order comes in, I need to know instantly whether the right panels, paints, fillers and fast-moving consumables are on hand and, if not, receive an alert before the customer even finishes the intake process. Here is how I picture it working. Every item shelf, paint cabinet and parts bin is fitted with a sensor solution—RFID, weight sensors or another technology you recommend—that feeds live counts to a cloud dashboard. When counts dip below a preset threshold, the system suggests a purchase order or flags it on a tablet that my front-desk staff already uses. Because the goal is...

I’m building an industrial-grade robotic setup and need a sharp embedded-systems mind to move the control electronics from concept to reliable hardware-in-the-loop operation. The work centres on firmware that drives motors, interprets sensor data and communicates over CAN bus or OBD-II–style diagnostics. Most of the prototyping will happen on Arduino or ESP32 boards before we freeze the design onto a custom PCB, so familiarity with Altium Designer or KiCad for schematic capture and layout is essential. Here’s how I see the collaboration flowing: • Translate high-level motion requirements into C/C++ firmware with clean, well-commented code. • Select, integrate and tune motor drivers, encoders and safety interlocks so the robot meets industrial-speed repeatab...

I have a Particle Boron and want it turned into a small proof-of-concept that watches two reed switches and a single split-core current transformer. Whenever either switch changes state or the CT reports a reading outside user-defined limits, the Boron should push an SMS straight to my phone. Please build the firmware, wire the sensors, and set up the cellular messaging so the text includes three key pieces of information whenever a condition is met: the live state of each reed switch, the measured current, and a timestamp noting when the limit was crossed. I also need your guidance in deciding the actual thresholds for both the switches and the current transformer, so factor parameter-setting into the workflow. A concise wiring diagram, commented source code ready for Device OS, and a q...

I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. Delive...

I’m bringing an MLX90614 infrared temperature sensor into an ESP32-based design and need a clean, ready-to-flash solution that covers three essentials: accurate temperature readings, an immediate on-screen display, and reliable data logging. The job breaks down into two parts. First, document the wiring so I can reproduce it quickly—pin map, I²C pull-ups, and power considerations for the 3 V rail. Second, supply well-commented Arduino-compatible code (ESP-IDF is fine if you prefer) that: • polls the MLX90614 at a reasonable interval • streams both object and ambient temperatures to the Serial Monitor (or an OLED/Nextion screen if you think that’s cleaner) • stores each reading with a time stamp to SPIFFS or a micro-SD card—your call, as l...

I have a junior engineer building the early schematics for an asset-intelligence prototype and I need an experienced embedded-systems specialist to guide the hardware design, write the firmware, and get the first units reliably streaming data to the cloud. The boards must interface with temperature, pressure and motion and more sensors, carry out real-time analysis, perform basic filtering, then aggregate and compress the packets before they leave the device. Security on the wire is non-negotiable, so please be comfortable implementing encrypted transport and key management on resource-constrained MCUs. You will collaborate directly with us on: • Selecting the optimal MCU / wireless stack and finalising the schematic • Integrating the three sensor types and validating their ...

I already have the basic LoRa modules on hand and now need a complete solution that turns them into a smart lamp I can manage from a browser. The lamp must offer smooth dimming, full-spectrum colour change and the ability to follow a user-defined schedule. Through the web app I want three distinct control modes: • a real-time dashboard where sliders and colour pickers immediately push changes over LoRa, • optional voice commands (Web Speech API or similar) for hands-free operation, • and a panel of quick “predefined settings” such as reading, relax or wake-up scenes. Please handle both the embedded side (firmware for the LoRa node driving the LEDs) and the front-end/back-end that serves the browser interface. I’m comfortable hosting on a small VPS...

I need robust, well-documented firmware that lets an ESP8266 on the Arduino platform both send and receive infrared commands for multiple air-conditioner remotes. Serial command-line interaction over USB or Telnet is all that’s required; no web or mobile interface is necessary. Core tasks • Build or adapt an Arduino-compatible sketch that scans incoming IR frames, decodes them, and logs the raw timing as well as the decoded protocol and data. • Implement a complementary routine that allows me to replay captured frames or craft new ones from the command line, then transmit them through an IR LED with correct carrier frequency and timing precision. • Structure the code so adding or tweaking protocols is straightforward—I will be experimenting with a variet...

I need a full EasyEDA project—schematic and routed PCB—for a tiny Atmega32U4 board that lets a computer drive a single external LED through a 3-pin XH-JST connector (GND / 5 V / LED). The board must talk and be programmable over a horizontal USB-C port and should remain as small as practical without sacrificing good layout practice. Core requirements • EasyEDA schematic using the Atmega32U4, including crystal or resonator, USB-C E-Markers (where needed), ESD protection, boot-cap circuitry and the standard reset network. • Break-out to one XH-JST-3 plug clearly silkscreened with the GND, +5 V and LED symbols. • Primary power supplied by USB-C 5 V rail. • Firmware that gives basic functionality: detect USB power, expose the MCU as a simple USB HID to ...
