...behaves exactly as designed. 2. Writing the Arduino firmware that listens to those commands, drives the motors and other actuators, polls the attached sensors, and feeds live values and alerts back to the screen. All three interface tasks are in scope—motor or actuator control, sensor monitoring, and displaying real-time information and adjustable settings—so the sketch will need a clean, well-documented serial protocol that keeps everything perfectly in sync. You’ll have access to the hardware in my workshop (Bangkok area); on-site sessions are important for testing cabling, timings, and noise issues that rarely show up on the bench. Remote prep is fine, but final integration must happen here. Deliverables • Compiled DGUS firmware and project...

I have a new Segway-style scooter in development and need a seasoned embedded programmer to create the entire self-balancing (gyro/IMU) firmware that will ship on the production boards. The scooter is meant for personal transportation, so reliability, safety and a polished riding feel are non-negotiable. Above all, the control loop must react instantly to rider input—acceleration, braking, tilt corrections—without hunting or lag. I will provide hardware access for bench testing as well as real-world ride data; you will transform that into a finely tuned PID (or equivalent) solution that keeps the deck level and feels natural underfoot. Beyond the core balancing logic, I want a highly customizable interface layer: riders should be able to tweak parameters (speed limits,...

...and premature belt failures disappear. My vision centres on a robust mechanical layout married to intelligent control. Integrated real-time tension monitoring, wear-detection sensors and load-variation sensing will feed a compact controller that drives the motorised actuator. Wireless control and monitoring must let operators check status or initiate overrides from a tablet if needed, and the firmware should generate predictive-maintenance alerts long before an issue escalates. I am looking for concepts worth patenting, so novel kinematics, sensing arrangements or control algorithms that aren’t yet standard in the market are highly prized. Deliverables • Concept options with novelty analysis for patent potential • Detailed 3-D CAD of the chosen mechanism, in...

I need a BMW coding specialist to remotely code a replacement OEM amplifier in my 2006 650i E64 convertible so the subwoofer channels are re-enabled. The job is strictly VO/FA coding (SG_CODIEREN); no manual FSW hex edits and no firmware flashing are required. What is already in place • Freshly installed used OEM amp that simply lacks the correct vehicle order • K+DCAN cable and a Windows laptop on my end, ready for your remote connection Scope of work 1. Read the vehicle order from CAS. 2. Apply the correct VO to the new amp with SG_CODIEREN. 3. Verify the subwoofer channels are active when coding completes. I’d like to observe the entire session, so let me know whether you prefer AnyDesk, TeamViewer or another solution and we’ll agree on the...

I need a concise firmware pair that lets one ESP32 talk to an ESP32-C5 through Firebase. The goal is straightforward: push a small JSON payload from the first board, have it appear on Firebase almost instantly, then pull it down on the second board so it can react (toggle a pin, echo the data, or similar). I will flash both boards myself, so your work ends at well-commented source code and a quick setup guide. You can build in Arduino IDE or ESP-IDF—whichever you feel gives the cleanest Firebase implementation. Wi-Fi credentials, Firebase project keys, and any sensor stubs can be hard-coded placeholders; I’ll replace them during testing. Deliverables • Two compilable sketches (or IDF projects) — one for ESP32, one for ESP32-C5 • Minimal Firebase r...

...CAN messages to RX (typ. every 10–20 ms, to be finalized). RX (Receiver) • Receives CAN data and controls outputs. • Power outputs must be implemented using VN5016AJ (one per channel, per design). • Maximum output current: 5A per channel • Output voltage level: 12V or 24V (powered from the same 9–27V supply). • Outputs must support PWM and/or ON/OFF control (hardware must be PWM-capable; firmware can be basic/test-level). ⸻ Industrial / Electrical Requirements • Supply: 9–27V DC • Input power protection: • reverse polarity protection • surge/transient suppression (TVS) • EMI filtering (LC / choke) • Local power rails: • buck regulator (9–27V → 5V and/or 3.3V) • stable 3.3...

...outside a range I’ll define, the ESP32 should trigger automated adjustments to the connected fan and light (for example dimming, speed changes, or temporary cut-off) without users having to intervene. Manual on/off toggles or rigid schedules are not required at this stage. Please build the mobile app (cross-platform is ideal, but I’m open) and deliver clean, well-documented source code plus any firmware tweaks needed on the ESP32 so the control loop is seamless. MQTT, WebSocket, or HTTP can all work; choose what you are most comfortable with as long as latency stays low and the code is easy to expand later. A short README outlining setup, compilation, and how to add new appliances will complete the job. If the above sounds clear, let’s get started—I&rsqu...

...authenticate securely (WPA2 minimum), and push three distinct data streams—usage statistics, diagnostics snapshots and real-time alerts—through the API endpoints I will supply. • Throughput: normal operating load is small, but latency for real-time alerts must stay below two seconds under full meter count.

...spinning up a fresh Ubuntu VPS and need it turned into a rock-solid hub for my IoT fleet. The box must host two main services—Mosquitto for messaging and a Mender server for over-the-air firmware updates—without compromising security, performance, or future maintainability. Here’s the picture • Mosquitto will run behind TLS with mutual authentication. I’ll give you the root CA; you generate and stage broker and client certs so the standard mosquitto_pub / mosquitto_sub TLS test passes. • Mender must be installed in its open-source edition, set to distribute only signed artifacts. I already sign firmware; the server simply has to enforce signature checking before rollout. • fail2ban on the host should block any source IP after t...

This is not a production-ready or industrial device. Expected Workflow Phase 1 – Audit Review PCB files and existing firmware Identify blocking issues Decide whether PCB changes are required Provide a short written audit report Phase 2 ...

...logic and hardware configuration, identify firmware or parameter discrepancies, and then implement improvements that boost stability and cycle-time performance. After each change I expect clear documentation describing what was adjusted, why, and how to roll back if ever required. Because the install is proprietary FA Feurer equipment rather than a mainstream Siemens or Allen-Bradley rack, prior, hands-on experience with FA Feurer tools, programming environment and diagnostic utilities is essential. Comfort working with fieldbus layouts, network topology checks, and controller backup/restore procedures will make the difference. Deliverables • Verified backup of the current controller programs and network configs • Updated controller firmware or logic with c...

Acceptance criteria • Prototype air-tested at 1 km minimum, documented video proof of stable feed • Latency consistently under 120 ms headset-to-drone round trip • Complete parts list, wiring diagram, and firmware dump so I can replicate or repair the build • Short us...

My current STM32G431 firmware already handles sensor-integration tasks and streams data from an external radar sensor. I now need the MCU’s built-in temperature sensor brought into that same workflow so I can log and display both ambient and component temperatures in real time. Here is what I’m after: • Enable and configure the STM32G431 internal temperature peripheral through CubeMX/HAL or direct register access—whatever keeps code size minimal. • Sample, convert to °C, and push the two resulting values (ambient and the MCU’s own junction temperature) into my existing data structure alongside the radar readings. This is to calibrate the radar measurement wrt temperature • Update the current UART/CAN publishing routine so the new te...

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP3...
