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 ...

I already have a functioning Python-based scraper on a Raspberry PI that targets a small set of information from a website, but I now need it to do more. The immediate priority is to extend its reach so it can reliably pull more information from a specific site to be used in a bot. The scraper currently pulls overtime information released at specific times and allows me to select an ID number for assignment. I want to upgrade it to handle multiple selections simultaneously. Additionally, I need the bot to rank weekend overtime assignments (assigned via lottery) and monitor for dropped assignments in real-time, automatically claiming them based on preferences. While we are inside the code, I would also like to broaden what the bot can do once the data is captured. It is already linked ...

I’m looking for a complete design-and-build solution for a smart dispenser that can handle dry food, wet food, and a variety of home-cleaning products in a commercial environment. The core requirement is an automatic sensor-based mechanism that lets customers select and fill exactly the quantity they need, reducing waste while streamlining self-service. Functionally, the unit should: • Recognise a container placed beneath the spout, trigger dispensing automatically, and stop precisely at the chosen weight or volume. • Keep wet and dry chambers fully sealed to avoid cross-contamination, odour transfer, or moisture ingress. • Be robust enough for daily public use—think stainless steel or food-grade polymers that are easy to wipe down and resistant to aggress...
