Firmware Jobs

I’m developing an adult-sized wearable headband that delivers gentle, targeted neurostimulation to restore healthy neural pathways and, in turn, improve overall cognitive function. The device must measurably elevate attention, focus, processing speed, and problem-solving skills for users whose brains are currently underperforming because of injury, illness, or chronic stress. Here’s the vision: • Hardware. Slim, comfortable headband housing a safe, rechargeable power source, adjustable electrodes, and an embedded control board capable of multiple stimulation protocols (tDCS, tACS, or another evidence-backed method you propose). • Sensing & feedback. Lightweight EEG or comparable sensors to detect baseline activity and adapt stimulation in real time, feeding da...

I’m upgrading a Duet 3D tool-changer running RepRapFirmware 3.6.0 + DWC and I need a custom “Run Reverse” plugin that mimics LinuxCNC’s M52 behaviour. The heart of the job is rock-solid, accurate reverse-feed: when a monitored sensor value crosses a set threshold the machine must instantly rewind the just-executed toolpath, then continue forward exactly from the last G-code coordinate once conditions normalise. Key operating model • Sensor data will be polled every 50–100 ms; this cadence is non-negotiable because of existing hardware constraints. • While reversing, feed must remain adaptive from +200 % down to –100 %, with smooth transitions to avoid step-loss or motor stall. • Stabilisation is dynamic: the cycle length and number ...

We have a working NVR alarm server but **cameras are only sending alarm status notifications (SendAlarmStatus) instead of actual alarm data with images (SendAlarmData)**.

The goal is to build a smart security camera that reliably spots any movement in its field of view and responds in real-time. General motion detection—not facial recognition or object-specific tracking—is the core of the project, so the software stack and hardware selection need to prioritise accurate, low-latency change-of-scene analysis. Night-time performance is essential. Infra-red night vision must be integrated so the camera can maintain the same detection accuracy in low-light or no-light conditions. If you can keep the IR LEDs power-efficient while still providing a clear 10-15 m range, that would be ideal. Video should stream in at least 1080p and store locally (micro-SD or on-board eMMC). I am open to cloud storage or two-way audio later, but those features are seco...

I am building a proof-of-concept robot for a government brief and need someone who can take the project almost to completion—hardware assembly plus all the code. Core functions The model has to spot potholes, measure local AQI, recognise severe impacts that suggest an accident, and automatically trigger a door-opening servo. All captured events must travel long-range to an Android APK without relying on Bluetooth; GSM, LTE or any other SIM-based link is acceptable. If a crash is confirmed the robot must also place an automated voice call to an emergency number. What I already have • Concept sketches and a basic parts list • Space allocated for three sensor blocks: pothole, AQI and accident detection Everything else—wiring, microcontroller choice, enclosure tweak...

Quiero el firmware completo para nodos esclavos de un sistema distribuido que utiliza LoRaWAN. Los esclavos con la placa heltec cubecell ab02s (htcc-ab02s) que soporta IDE Arduino, que se comuniquen por LoRa de forma bidireccional con el maestro. Y para el maestro que es una Raspberry Pi con Node-Red y desde ahí se comunica con los esclavos. Funciones de los esclavos • Medición periódica de caudalímetros que utilizan rs485 y entradas rápida/interrupciones. • Acción sobre electroválvulas. • Configuración de parámetros internos, tiempos de modos sleep, alertas cuando la temperatura supere o baje de los umbrales definidos, gestión de batería... Requisitos del maestro • Crear y gestionar las tra...
