This project builds direct peer-to-peer connectivity using secure mTLS tunnels over IPv6, allowing users to load websites hosted locally on each other's machines. It also supports coordinating traffic through a relay to avoid publishing public IPs, aiming to recreate the "old" internet with everything mTLS-protected and end-to-end encrypted.
An offline-first animation webapp built on CRDTs to support eventual team collaboration features. Tweening was just implemented, with video export planned next.
Open source replacement control firmware for Masterbuilt Gravity series electronically controlled charcoal smokers, reverse engineered from the stock control PCB and rebuilt from scratch. Basic functionality is working with a fully local control web app, plus an Android app and Home Assistant integration. Ongoing work includes interface refinements and more advanced control sequencing features.
A reverse engineering project that dissects the hardware and firmware of the Sony A7 IV camera.
A hobby robotics project: a robot designed and built to construct wooden hardwood decks using the edge-screw method.
This website tracks AI compute prices, using 53 price collectors to gather pricing data with the goal of making the economics of AI easier to understand. Planned additions include kWh (electricity) prices and robot prices.
A robotics information and news website that aggregates coverage of the robotics field.
Applies DBSP theory to Postgres and DuckDB to enable incrementally maintained materialized views.
This cloud platform lets researchers run molecular dynamics simulations on GPUs with a simple usage-based pricing model, simplifying setup for materials science problems such as battery electrode performance as an alternative to traditional HPC.
A home baking project making eggless applesauce oatmeal cookies and chocolate chip cookies.
Web app from the OneBusAway open source public transit suite, deployed by University of California San Diego for its 35,000+ students.
Web app from the OneBusAway open source public transit suite, deployed by University of California San Diego for its 35,000+ students.
Android app from the OneBusAway public transit suite, which recently launched a redesign.
Next-generation server software from the OneBusAway public transit suite, approaching version 1.0.
This tool edits and flashes BMW engine maps (N13, N20, N55, S55, B58, S58) and transmission control unit (TCU) maps (ZF8HP45 and ZF8HP50) for vehicle tuning.
This iOS and Android app provides remote access to BMW vehicles over an ENET connection.
A deployment tool built as a replacement for Octopus Deploy, designed to handle many small projects affordably. Nearly all core functionality is working, with current work focused on improving UX for the most-used workflows and adding support for other usage patterns before release.
This analog electronics project uses a programmable unijunction transistor (PUT) to simulate an integrate-and-fire neuron, experimenting with variations of pulse-width and frequency of the input spike train to see how they affect when the neuron fires. Planned next step is adding a resistor to bleed charge from the timing capacitor to make it a leaky integrate-and-fire neuron, as part of the author's explorations in neuromorphic and analog computing.
Small scripts that query the local bus company's API to show when buses are arriving at stops, designed to eventually output the arrival data to an external display. Built with simple, understandable scripts and included curl examples because similar existing projects were hard to understand and relied on a deprecated API.
A change control app the author wants to build with Rails (using AI during development). It provides templates for requests for change, visual indicators of an RFC's stage in the workflow, and clear guidance on exactly what needs to be done to push each change along, aiming to be a less painful alternative to ServiceNow's change control.
This app integrates a softphone, email client, CRM, and task manager into a single communication and business tool, replacing the author's existing white-labeled third-party app.
A web-based FFmpeg command builder that generates common ffmpeg commands. Originally built around 7 years ago in Vue2 and Bootstrap as a simple static frontend tool, it was recently refreshed as version 2.0, ported to a Vite/React/Tailwind static frontend.
Beauty is a free markdown note app that runs entirely on-device. It supports slash commands for styling, ':' for emojis, and text shortcuts like '< 3' for a heart or '- >' for an arrow, inspired by input behaviors from AI coding editors. It offers live multiplayer editing like Google Docs but P2P over WebRTC with strong cryptography, limited to sharing files while they are open. Rendering, GPU, RAM and bundle sizes are heavily optimized, with the Mac app under 50 MB; an iOS version with iCloud sync is planned soon.
An analytics store that keeps Postgres data on S3 and uses DuckDB as the query engine.
A Common Lisp operating system capable of diverse double compilation and booting on a Raspberry Pi.
A personal sponsorship effort by a long-time OpenBSD contributor: a 'wall of pizza' page that solicits monthly sponsors and one-off donations (including bitcoin) to fund more of their time on open source development and advocacy, using their own hand-built HTML page to attract supporters.
A self-hosted GitHub Actions runner built on k3s/k8s that supports macOS and Linux workloads, intended to replace paid GitHub-hosted runner minutes.
A personal homelab being secured and tinkered with as an ongoing infrastructure project.
A set of small utilities that make repeated deterministic functions easier for the user and agents to run.
Tenjin is a knowledge layer for AI agents so they stop duplicating work. It rides Claude Code/Codex hooks to capture useful information and injects it when needed (such as when an error occurs) for other agents. Knowledge is shared across a team and a global marketplace layer with incentives for contributions. It is currently being benchmarked with an aim of 10% token reduction, and preliminary design partners are being accepted.
