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.

node-red raspberry pi camera camerapi

node-red-contrib-camerapi

A Node-RED node to take photos on a Raspberry Pi. This node will only work on an Raspberry Pi with a Raspberry Pi Camera enabled.

Installation

Run the following command in the root directory of your Node-RED install or home directory (usually ~/.node-red) and will also install needed libraries.

        npm install node-red-contrib-camerapi

Additionally you have to install on the Raspberry Pi

First you have to install a Raspberry Pi Camera physically and don't forget to enable the Camera in raspi-config. See Pi Camera setup. Also check if you have installed the picamera module for python.

        sudo apt-get update
        sudo apt-get install python-picamera python3-picamera

If you are using the default path during the fileoption set - the path /home/pi/Pictures will be used.

Runtime information

This node is tested on RASPBIAN (buster), Nodejs V12.x LTS and NPM 6.x on Node-Red 1.0.6

Usage

TakePhoto

This node is to take a photo in a given format directly from the Raspberry Pi Camera. Using the Filemode the image of the photo is stored into the file-system and msg.payload will give you the path and the filename including extension to the photo. In Buffermode the image will reside as a buffer in msg.payload. For the possible parameters see documentation under picamera parameter settings.
