30 Days of Code
Orcas v1.5 challenge · Buildcored
30 small Python projects, one per day, built for Orcas v1.5, the 30-day challenge run by Buildcored, an open source builder community from Tashkent. The rule was simple: ship something that works every day.
Four themes
Body as input, local AI on the laptop, signals and systems, and full systems. Most days use the webcam, the microphone, or a local LLM through Ollama.
Highlights
Drawing in the air with hand tracking, a command line agent running a 3B parameter LLM fully offline, a local retrieval augmented generation system for hardware datasheets, a two level CPU cache simulator, and OrcaOS, a terminal dashboard that combines the challenge projects.
Tools
Python, OpenCV, MediaPipe, NumPy, Matplotlib, Ollama
