My Dell PowerEdge M630 is throwing simultaneous faults for both the IO Module and the iDRAC in the Chassis Management Controller. These errors began right after I swapped in a new NDR Broadcom module and an RSPI card, so I suspect either firmware mismatch, configuration drift, or a seating/compatibility issue. Your task is to diagnose and clear those alerts, restore full iDRAC access, and bring the IO Module back online so everything shows green in the CMC. I can supply CMC screenshots, current firmware versions, and remote KVM access; if reseating or component swaps are needed, I’ll be on site to follow your instructions. Acceptance criteria • CMC recognises and reports the IO Module and iDRAC as healthy • Network ports tied to the IO Module come up and...

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, car...

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,...

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/LED matrix is fine), and confirm delivery. • Low-power strategy outlined and demonstrated so the device can idle for weeks on a fresh battery yet wake instantly for message activity. • A 3-D printable enclosure fi...

...electrical and software-programming sides of my machine-building project. The mechanical portion is already under control in-house, so your focus will be integrating, testing, and refining the control electronics and embedded code that drive the system. You should be comfortable reading and updating wiring schematics, selecting or replacing critical components, and writing clean, well-documented firmware or PLC logic that keeps everything running reliably. If you can also implement quick diagnostic routines and safety interlocks, even better. Scope at a glance • Review existing electrical design, spot weak points, propose improvements • Develop or optimise the control software (C/C++, Python, or ladder logic—whichever best fits) • Support bench-top te...

I need someone to: • Plan and configure the wired backbone (VLANs, trunking, QoS) • Optimise WiFi coverage, assign channels, and fine-tune roaming settings • Harden the entire network with firewall rules, WPA3, and up-to-date firmware Most of the hardware is already on-site and powered up; it just isn’t talking to each other reliably. You’ll start with a quick audit, document the current layout, propose any tweaks or firmware upgrades, then implement the agreed changes. Clear, step-by-step documentation should be delivered so my in-house team can handle basic moves, adds, and changes after you’re done. Acceptance criteria 1.

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 tha...

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. • Safe...

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, int...

If you can drop in custom patches, rebuild the firmware, or guide me through buildroot changes, even better. I’ll supply real-time logs (logread, dmesg), wireless captures, and access to remote serial consoles as required. Let&rsq...

Several Windows 11 workstations need attention from first boot through everyday usability. The scope covers three distinct but related tasks: • System setup & configuration – imaging or clean installs, driver updates, user profile creation, network and peripheral configuration. • Hardware repair & maintenance – diagnosing faulty components, replacing parts when required, checking firmware, and leaving each machine with a clean bill of health. • Software installation & troubleshooting – loading line-of-business apps, validating licences, applying patches, and resolving any errors that arise during or after deployment. All machines are running the latest build of Windows 11; no other operating systems are involved, so in-depth k...
