Raspberry Pi Jobs

I’m putting together an all-terrain rover that pairs a Raspberry Pi 5 with an Arduino. The Arduino will sit close to the hardware, polling and driving everything from temperature-humidity probes and distance sensors to an IMU (pitch/yaw/roll, altitude, compass), ESC-PWM motor controllers, speed-over-ground tracking and battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value pl...

I need a concise Python 3 script that will run on a Raspberry Pi 5 and do the following: • Watch a single GPIO input line for the HIGH digital signal coming from my Sony camera’s built-in AI output. . The Sony camera will be pre-loaded with images of the target - in this case a plant which is detected in the target bounding box in the camera field of view. . When the target plant is encountered in bounding box of the camera field of view, the corresponding relay will activate a spray nozzle for the time the target remains in the bounding box. •The point above is achieved as soon as that digital signal is detected, drive a separate GPIO output that energises a small 5 V solenoid for as long as the target plant remains in the bounding box of the camera, then automatical...

I am looking for an experienced PCB designer to create a 4‑layer carrier board for a Raspberry Pi Compute Module 5 (CM5). The board integrates several existing open‑source hardware concepts into a single PCB, with limited original R&D but careful integration and cleanup. Scope of this first project - Review and consolidate existing reference schematics (I will provide open‑source designs and documentation). - Design the final schematic for: - Raspberry Pi CM5 + power supply - CAN‑based bus for a marine/industrial network (NMEA‑style) - NMEA 0183‑style serial interfaces - Connectors and I/O suitable for a small boat/embedded environment - eDP interface for an external display - PCB layout: - 4‑layer stackup with proper impedance control for eDP - Rea...

I’m building an educational, IoT-enabled play mat designed especially for children aged three to five. When a child steps, taps or sits on different zones, I want the mat to recognise the interaction and trigger playful learning responses—lights, sounds or messages sent to a companion mobile app. Here’s what I need from you: • Hardware logic so each zone on the mat can reliably detect pressure or touch and send that data wirelessly. • Firmware that converts those raw sensor readings into tidy, low-latency events the app can understand. • Simple proof-of-concept software (mobile or web) that shows the events, plays a sound or displays a visual so I can demo the core learning activities. I’m open on the exact platform; ESP32, Raspberry Pi Pico W ...

I need a production-ready wake-word model that reliably responds to “Hey Bobo” on both ESP32 and Raspberry Pi boards. Accuracy is critical: in a moderately noisy room it should trigger every time someone clearly says the phrase, yet ignore most unrelated speech. I still want slight phonetic wiggle-room—utterances such as “hello bo,” “hey bebo,” or “hello bebo” should wake the system as well—so fine-tuned threshold settings and a well-balanced dataset will be essential. What I expect from you • A trained wake-word model or firmware that runs in real time on ESP-IDF for ESP32 and on Raspbian/Ubuntu for Raspberry Pi without requiring cloud calls. • Demo code that shows how to load the model, stream audio from an onboar...
