Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Signal K APRS Plugin

This plugin integrates Signal K with the Automatic Packet Reporting System (APRS), a packet radio system for Radio Amateurs. The plugin connects to various APRS-capable radio systems using the KISS TNC protocol.

You need to be a licensed radio amateur to use APRS. For everybody else, Signal K Meshtastic Plugin is the way to go.

APRS is a registered trademark Bob Bruninga, WB4APR.

Status

Very early stages, being tested with the LoRa APRS iGate firmware.

Features

  • Support for connecting to multiple KISS TNCs
    • This allows connecting to both LoRa APRS and VHF APRS for instance
    • TX can be enabled separately for each TNC, allowing listen-only connections
    • The plugin will keep trying to reconnect to TNCs that are offline
  • Periodically sending vessel position as a beacon to TX-enabled TNCs
  • Populating received WX stations into Signal K data structure

Planned features

  • Transmit WX data from boat sensors (wind, temperature, etc)
  • Send telemetry (battery status, water depth, anchor distance) over APRS
  • Show other APRS beacons as vessels in Freeboard etc
  • Send alerts to crew over APRS
  • Figure out how to handle APRS messaging from/to boat

  • 0.2.1 (2026-01-20)
