Open-source USB-C PD analyzer and programmable supply

Open-source USB-C PD analyzer and programmable power supply built on the ESP32-C3. Set any voltage from 3.3V to 21V with 20mV precision, monitor current draw in real-time via WiFi or BLE, and log power consumption over time. Full transparency — inspect the schematic, modify the firmware, or manufacture your own.

Turns USB-C power debugging from guesswork into a repeatable workflow.

Ultra-low-power motion tracker designed for wearables

Ultra-low power IMU tracker that runs 30+ days on a CR2450 coin cell. Combines a 6-axis IMU with deep sleep between motion events and adaptive reporting. Compact enough to embed in any wearable — step counters, gesture controllers, sports trackers. Open-source design, TinyML-ready firmware.

Pushes useful sensing into tiny battery budgets and constrained devices.

Terminal deckbuilder that turns commit history into gameplay

Terminal roguelike deckbuilder with tactical grid combat. 70+ cards across 4 categories, 3 multi-phase bosses, 20 relics, and 15 ascension levels. Cards can be played instantly or emplaced as persistent structures on a 5-column grid — turrets deal damage each turn, barricades block, beacons heal. The hook: it reads your local git commit history and grants bonus HP based on how active a developer you've been. Built with Ink/React.

Makes developer activity feel playful instead of administrative.

Offline coding agent that acts on files and commands directly

AI coding CLI powered by Ollama — 100 GitHub stars. No API keys, no cloud. Unlike tools that just generate code blocks, ollamacode calls tools directly — creating files, running commands, and managing git on your behalf. Supports multi-file context, session save/resume, and 14+ language syntax highlighting. Works with any Ollama model that supports tool calling.

Brings agentic coding workflows to local models without cloud dependency.
