DesktopFly is a macOS desktop companion that places a procedural 3D fruit fly on a transparent, click-through overlay. The fly walks across window edges, grooms, sleeps, flies, and responds to cursor movement, clicks, window changes, keyboard activity, time of day, and thermal state without requiring permissions or entitlements. A separate interactive brain window displays 23,210 FlyWire neuron soma positions and live spikes. Its behavior is driven by a 1 kHz leaky-integrate-and-fire simulation of a 668-neuron circuit containing approximately 19,000 real synaptic connections. Cursor approach is converted into looming input for LC4 and LPLC2 visual neurons; escape is produced only when activity reaches the DNp01/Giant Fiber escape command neuron through the modeled synapses. Other circuit outputs drive walking speed, steering, grooming, backward movement, wing effort, escape maneuvers, arousal, and spontaneous takeoff. The loop also feeds gait rhythm to ascending proprioceptive neurons and fast cursor motion to sensory wind partners. The body geometry and sensory transduction are procedural or modeled, while the downstream connectivity and synaptic strengths come from FlyWire data. The project targets macOS 13 or later and requires the Xcode Command Line Tools. Menu-bar controls provide pausing, brain-window visibility, escape testing, movement between displays, adding or removing flies, and starting a collective startle response; the brain window can stimulate nearby circuit neurons for 400 ms. The code is MIT-licensed, while derived FlyWire data files are CC BY-NC 4.0.

BirdNET-Go is a tool that identifies bird species from environmental audio.

Paper Aquarium is a home game that turns a child's marker-colored A4 sheet into a 3D fish swimming in a browser aquarium, with a phone used to capture the sheet and a large screen used for viewing. Four black corner markers identify the sheet and its species while allowing the capture code to locate it in the photo and undo perspective distortion. The system then crops the drawing along the species contour, removes the printed outline, and maps the result as a texture onto a Three.js fish model; the aquarium positions fish within a camera-frustum-shaped volume and infers their orientation from the animation's tail movement. It includes ready-made fish, food, coloring sheets, backgrounds, multiple aquariums, and phone-to-TV handoff through a QR code, link, or five-digit code. The server uses plain Node with no dependencies, with Three.js stored in the repository; it requires Node 18 or later.

Tinta is a battery-powered e-paper sign built around the Raspberry Pi Pico W. A real-time clock wakes the device on schedule; it retrieves data over Wi-Fi, redraws the display, and switches the hardware off completely rather than using sleep mode. A push button or optional NFC tag can also trigger a wake-up, allowing uses such as room signage, sensor graphs, home automation, weather data, and desk booking. The repository contains Pico W firmware in C, a custom KiCad PCB, a 3D-printable enclosure, and an optional Python/Flask telemetry service. The PCB includes the real-time clock, MOSFET power switching, battery monitoring, and optional NFC hardware; the e-paper retains its image while the device is powered off. Firmware supports OTA update slots and documented use cases including Seatsurfing, CCU-Historian, Homematic, and weather data, and can also run on an unmodified Pico W with the display disabled. The hardware is licensed under CERN-OHL-S-2.0, while original firmware is licensed under Apache License 2.0. The project was formerly published as inki.

Renfield is a self-hosted, voice-first AI household assistant built with FastAPI, React, and Ollama. It uses Raspberry Pi Zero 2 W voice satellites with ReSpeaker HATs for local wake-word detection, Whisper speech recognition, Piper text-to-speech, and SpeechBrain speaker recognition. The system can track room presence through BLE scanning, voice recognition, and web authentication, and integrates with Home Assistant and DLNA for multi-room control. Its ReAct agent chains tools through 10 MCP servers covering weather, web search, news, calendars, Jellyfin, DLNA, n8n workflows, Home Assistant, Paperless, email, and related services. It also provides conversational long-term memory with contradiction detection, a knowledge graph with validated entity-relation triples, and a RAG knowledge base that combines dense pgvector embeddings with BM25 full-text search using reciprocal-rank fusion. Documents can be uploaded from formats including PDF, DOCX, PPTX, XLSX, HTML, Markdown, and TXT, with Tesseract or EasyOCR available for scanned or poor-quality PDFs. The project is designed to run entirely on local hardware without cloud dependencies and includes a web interface, satellite monitoring, proactive notifications, plugin hooks, and Paperless document-audit workflows. The repository describes more than 100 available tools and supports Docker-based self-hosting.
