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 🙏

delcom-indicator

v1.0.4

Published

A library to drive the Declom Visual Indicator (http://www.delcomproducts.com/products_usblmp.asp)

Readme

delcom-indicator

A node library to drive a Declom Visual Indicator

Our development roadmap is on the delcom-indicator Trello board

##Install

npm install delcom-indicator

##Use

var DelcomIndicator = require('delcom-indicator');

var delcomIndicator = new DelcomIndicator();
delcomIndicator.flashRed();
delcomIndicator.close();

A more complete example is found in tests/spike.cs. The test opens an attached Delcom light and runs through the available functionality by turning it solid greed, red and blue and then flashing each color.

##Related Application

A Build Light indicator for TeamCity that utilizes this library to show the status of builds.

##Supported Platforms This library is known to work on Mac and Linux platforms where node-hid can be installed. It was designed and tested on Mac OS/X 10.9.2, Max OS/X 10.11.3 and Raspian (all updates installed as of March 12, 2016). It has not been tested on Windows but should work provided that node-hid can be installed. It requires Node 4.x or higher.

Depending on your platform, Node-hid may require a compile, which adds additional dependencies. See the node-hid readme for details.

On Linux you need to grant permissions to write to the Delcom device. On Raspian, you can create a file:

sudo nano /etc/udev/rules.d/85-delcom.rules

With the following rule (replace the group name with a group of your choice):

SUBSYSTEM=="usb", ATTRS{idVendor}=="0fc5", ATTRS{idProduct}=="b080", ACTION=="add", SYMLINK+="delcom", MODE="0666", GROUP="[your group]"

You will have to reboot to make the rule take effect.

##Development Prerequisites You need to install gulp-cli globally using:

npm install gulp-cli -g

You can then run tests using:

gulp

The tests require you to have a Delcom USB device connected.
