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 🙏

Node-RED Peak Value Range Node

This Node-RED node, named "peak-value-range," filters input values within a specified range and calculates the first peak value within that range.

Description

The "peak-value-range" node filters incoming values to ensure they fall within a specified range (minimum and maximum). It then calculates the first peak value within that range and emits it as output. This node is useful for finding the highest value within a specified range of analog or numerical data.

Installation

To install the "peak-value-range" node in your Node-RED environment, you can use the Manage Palette feature or manually copy the node files to your Node-RED nodes directory.

  1. Using Manage Palette (Recommended):

    • Open your Node-RED instance.
    • Click on the menu icon in the top-right corner and select "Manage palette."
    • Go to the "Install" tab, search for "peak-value-range," and click "install."

  2. Manual Installation:

    • Copy the "peak-value-range.js" and "peak-value-range.html" files to your Node-RED nodes directory (usually located at ~/.node-red/nodes).

Usage

  1. Drag and drop the "peak-value-range" node from the Node-RED palette onto your workspace.
  2. Configure the node by setting the minimum and maximum values for filtering.
  3. Connect the "peak-value-range" node to an input source that provides analog or numerical data.
  4. Deploy your flow.
  5. The "peak-value-range" node will calculate the first peak value within the specified range and emit it as output.

Configuration

  • Minimum Value: The minimum value for filtering input data. Values below this threshold will be ignored.
  • Maximum Value: The maximum value for filtering input data. Values above this threshold will be ignored.
