Raspberry Pi Jobs

I am building a proof-of-concept that lets a Raspberry Pi follow a user’s gaze and immediately translate that data into visual output on an attached screen. At the end of the job I want to be able to look at a point on the display and watch the system draw a corresponding dot, line, or free-hand stroke in real time. What I already have • Raspberry Pi 4 with camera interface available • Freedom to choose the most suitable eye-tracking library (OpenCV, MediaPipe, PyGaze, or similar) • One HDMI monitor for testing, though the code should remain display-agnostic so I can later swap in a touchscreen or e-Ink panel without major refactoring. What I need from you • Set up and calibrate the camera-based eye tracker on the Pi • Translate raw gaze coordinat...

I need a working prototype of a fully-automated roti-making machine that can turn out 100 soft, evenly cooked rotis in 30 minutes while keeping the total build cost under ₹10,000. Durability is my top priority: gears, belts, heating plates, and the overall frame must stand up to continuous use without needing frequent maintenance. Heating flexibility is also essential. The design has to accept both induction coils and standard gas burners so I can switch energy sources as required. From dough portioning and pressing to cooking, puffing, and neatly stacking, every step should run hands-free once ingredients are loaded. To keep the budget realistic, I’m open to clever use of off-the-shelf components, 3-D-printed parts, recycled food-grade stainless, or low-cost electronics such as Ar...

I need a compact, reliable humidity-logging solution that can capture readings at regular intervals and send them straight to Google Cloud Platform in near-real time. I am open to microcontrollers such as ESP32, Raspberry Pi, or any low-power alternative, provided the final build can connect over Wi-Fi or LTE and push data securely—ideally through Cloud IoT Core or Pub/Sub—into a time-series bucket I can later analyse with BigQuery or Data Studio. What matters most is that the entire path from sensor to cloud is proven and robust. You are free to suggest the specific humidity sensor, the firmware language (Arduino, MicroPython, C, etc.), and the best authentication method for GCP, as long as you keep power consumption modest and the solution easy to reproduce. Please highligh...

Buscamos un ingeniero electrónico o diseñador de hardware senior para diseñar la "BumbiPTT Interface": una placa base custom en KiCad que aloja una Raspberry Pi 3 Model B+ montada de forma invertida, diseñada para encastrar mecánicamente en un gabinete de extrusión de aluminio LK-ALW30 (204x54.1x120 mm). El circuito funciona como un gateway de audio y control para radio (VHF/UHF/Digital) por IP, con un requisito crítico de inmunidad a RF, separación de tierras y aislamiento galvánico de audio. Puntos clave del diseño (alcance exclusivo de diseño y DFM): Mecánica y Stackup: Montaje invertido de la RPi 3B+ con cutouts térmicos para disipación por conducción hacia el piso del ...
