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.

Webthing SK6812 RGBW Raspberry Pi

webthing-sk6812

A WebThings Thing for controlling a strip of SK6812 RGBW LEDs from a Raspberry Pi.

Pre-Install

This script relies on the rpi-ws281x NPM module, which does not currently support the SK6812. Until this pull request is approved, you will need to manually download this forked copy of the rpi-ws281x module.

Run the following commands from one level above.

$ git clone https://github.com/AlanDThiessen/rpi-ws281x.git
$ cd rpi-ws281x
$ git checkout sk6812

Install

$ npm install webthing-sk6812

Configure

Modify the parameters of the config object in index.js to match the hardware configuration.

numLeds: The total number of LEDs connected to the Raspberry Pi.
gpio: The GPIO line to use to control the LEDs (default is PWM GPI 18).
dma: The GMA channel to use.
- Default is 10.
- This may need to be changed if running on a Raspberry Pi 3 or later.

Run

Root/sudo privileges are required to write to PWM GPI line on a Raspberry Pi.

Start the following command on the Raspberry Pi.

$ sudo node ./index.js

Control

Use the WebThings Gateway to control this device.
Ensure the Web Thing Adapter is installed.
On the Things screen, click the + button to search and add devices. It should find the device SK6812.
