Software

A selection of things I've built and open-sourced over the years — the engine that runs this site, tools for astrophotography, open hardware and firmware, and a few distributed-systems libraries from my day job. Almost all of it lives on GitHub.

Photography & Astro

tenrankai

The engine behind this very site: a fast, flat-file gallery, blog, and CMS with no database and a serious image pipeline — HDR AVIF, ICC-correct resizing, and watermarking.

Rust
psf-guard

A screening utility for the N.I.N.A. Target Scheduler that sifts through astrophotography sub-frames and flags the keepers.

Rust psf-guard.com ↗
spacecat

Some Discord + N.I.N.A. nonsense for keeping an eye on an imaging session from anywhere.

Rust

Hardware & Firmware

pulsarfab/pulsarfab

An open-source hardware and firmware platform.

Assembly calcumaker/calcumaker

A make-your-own calculator — open hardware and firmware.

Rust ledbrick

LEDBrick — open hardware and firmware for programmable, high-power LED lighting.

C notchdeck

Open-hardware dual-mode (USB + BLE) train master controller — a "mascon" — built on the nRF52840.

C mcpwm_unified

An ESPHome component that unlocks the full MCPWM capabilities of the ESP32-S3.

C++ tsumikoro

Hardware and firmware for a contraption that makes a whole lot of spheres roll around. Exactly that.

C

Infrastructure & Distributed Systems

akka-quartz

Quartz-based scheduling for Akka actors — "because using Camel to schedule Akka actors is silly." My most-starred project.

Scala mediate

Retryable, failure-tolerant, adaptive HTTP client transports for Go.

Go statsdproto

Utilities for parsing and canonicalizing the statsd wire protocol.

Rust

Archive

Older projects — no longer actively developed, kept around for posterity.

pertempco

The "Perfect Temperature Controller" — precise, no-nonsense temperature regulation.

Rust entropyking

Open hardware: a USB-based true random number generator.

Hardware copper-avr32-breakout

Open hardware: a DIP breakout module for the AVR32 processor.

Hardware libevecache
