ESPHome HW211 Component
I published an ESPHome external component for HW211-family heat pump controllers, generating local Modbus sensors and optional controls for Home Assistant.
Heat Pump Hot Water Wi-Fi Adapter
I replaced the proprietary Wi-Fi module in my heat pump hot water system with a local ESPHome adapter built using a Waveshare ESP32-S3-RS485-CAN module.
Cloud-Free PETKIT Feeder
I converted a PETKIT Fresh Element Mini dry food dispenser to run locally with ESPHome, removing the need for a cloud connection.
Disk Shelf Fan Controller
I added an ESPHome fan controller to my disk shelf, using a DS18B20 temperature probe, PWM fan control, and a small script to log HDD temperatures.
Room Controllers
I turned my ESPHome LVGL light touchpads into reusable room controllers for lamps, weather, screen sleep, and per-room aircon control.

ESPHome weekly-ish roundup from Discord: BLE MIDI Remote for ESPHome, SnapSpot, and RealDeco's Sendspin Headphones.
ESPHome Weekly Roundup: 18th April
ESPHome weekly roundup for 18 April: a tiny Sendspin speaker amplifier, ESPControl for smart home touch pads, and esphome-zerocode.
Evening Lights with Ambient Lux
I updated my Home Assistant evening lights automation to use the ambient light sensor from my Ecowitt weather station, so the lamps turn on when it is actually dark.
Ecowitt Weather Station
I set up an Ecowitt weather station locally with WSView Plus and Home Assistant, then mounted the WS69 sensor array above the greenhouse.
Rocket Lamp
I converted a strange looking mains powered lamp to be USB-C powered and programmable using ESPHome.
Smart Soy Light
I converted a Heliograf soy sauce lamp into a Home Assistant controlled smart light using ESPHome.
wyoming-whisper-intel
I assembled a docker container or wyoming and whisper on intel GPUs. It is built on the intel/oneapi-basekit container.
Rathole Maintainer
I became a maintainer of the rathole project, which is a secure, stable and high-performance reverse proxy for NAT traversal, written in Rust.
caddy-hostnames
I released caddy-hostnames, which automatically publishes .local hostnames from Docker containers via mDNS using Caddy-Docker-Proxy.
freelens
This project provides a reference implementation of NaviLens and ddTag for educational or personal use.

binsmooth
I wrote a Python implementation of 'Better Estimates from Binned Income Data'. This technique allows distributions to be estimated from binned data.
Teacher Pay Comparison
I made a supplemental dashboard to accompany submission to 'Valuing the teaching profession' inquiry. The dashboard uses plot.ly Dash and the code is available on Github.
