I...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 or any microcontroller you feel suits a child-safe, low-power product will work. The finished prototype should be safe, responsive and easy to extend with new activities as the curriculum grows. Let me know which sensors, wireless protocol and development tools you prefer, how quickly you can deliver a working prototype, and any previous child-focu...

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,...

 Another approach is here: Attachment: 11.1 Another approach This little cartoon Pi character is cute without being cringeworthy. The story telling is very clear. BUT - it’s maths and science, and that is a lot easier to visually demonstrate than the complex psychological concepts I am talking about. I also guess this is not strictly AI, but I dont see why AI couldnt be directed towards something like this. However, it still needs to be directed. And obviously I wouldn’t have a PI character…so I am not sure how useful this example is in the end. There are the videos of Sabine Hossenfelder on YouTube, but I dont want this style. The image...

I want to browse safely from any hotel or coworking space by tunnelling all my traffic back to a small VPN server that will live in my house. The job has two parts: • Hardware advice – point me to a compact, reliable travel router and the best-value home server (could be a Raspberry Pi, mini-PC, dedicated router or NAS) plus any cables, power adapters, or memory cards I should add to the shopping cart. • Full setup – install and configure the VPN on the home unit, flash/configure the travel router, and hand me clear, copy-paste-ready instructions for connecting both my laptops/desktops and my iOS/Android phones. Secure browsing is the main goal, so strong encryption, a clean firewall policy, and DNS leak protection are mandatory. I’m flexible o...

I want a simple two-channel radio link that can do just two things reliably: 1) vary the speed of my brushless DC motor through its ESC (accepts S-Bus or standard PWM) and 2) toggle a single relay on or off. Hardware • I already have the motor, ESC, and relays. • You may choose Arduino, Raspberry Pi, or any Adafruit board—use whichever keeps the build small, inexpensive, and stable. Radio requirements • The handheld transmitter must let me select the operating band with a physical switch: 2.4 GHz, 900 MHz, or 433 MHz. • If LoRa is the cleanest way to hit those bands, great—just make sure the LoRa hop gives me at least a 1 000 ft (≈300 m) clear-line range. Long-range reliability is more important than data rate or extreme...

I need a compact, fast object-detection model that runs directly on an edge board (Jetson Nano, Raspberry Pi, Coral or similar) and processes aerial images from drones. The immediate application is surveillance, yet the solution should stay flexible enough to be reused later in agriculture or disaster-response scenarios. Source imagery will contain a mix of people, cars, buses, bicycles and assorted infrastructure. The model must be especially reliable at spotting people and critical infrastructure elements, while still recognising the wider vehicle classes.I am open to any justified architecture (YOLOv8, MobileNet-SSD, EfficientDet-Lite, or superior alternatives)—provided it outperforms YOLOv9c and similar models while delivering real-time inference on edge devices on...

I am building an end-to-end IoT monitoring system and need help finishing three tightly-connected pieces: • A Python script on a Raspberry Pi that collects sensor readings and publishes them to an MQTT broker. • A Django micro-service that preprocesses those messages before handing them to a Laravel / MySQL backend, where devices and users are registered and authenticated. • A React Native mobile app that runs on both iOS and Android and subscribes to the same broker for real-time data display. The mobile front-end’s first milestone is a clean dashboard that streams temperature, humidity, device operational status and any other sensor readings the Pi sends. Data has to update instantly without manual refresh, using MQTT over websockets. ...

I’ll be sending over prototype boards that plug into a Raspberry Pi. Your task is to put each unit through its paces, first on the bench and then as a fully-integrated stack with the Pi.

...setup with Raspberry Pi Zero W boards. One Pi acts as the master player; the second Pi will behave purely as a Bluetooth speaker. When a stereo .wav file is uploaded to the master, I need the right channel to play locally through its own audio jack while the left channel streams in real time over Bluetooth to the second Pi. If no Left speaker, then the wav file will play both right and left on the master PI. File transfer to the master should run over Wi-Fi or Bluetooth—whichever proves reliably fast enough—and I’d like the code to allow both paths so I can choose at runtime. On the master Pi I will wire two physical GPIO buttons: one toggles play/pause, the other triggers the file-upload routine. Please deliver well-c...
