The days are getting shorter and rainier so time to dust of the 3D printer. (RigidBot)
Today I finally reinstalled the parts fan to improve the print quality.

Today I took the day off to do something I have been planning for a while.
I made a KAKU (Klik aan klik uit) MQTT client to send and receive (new)KAKU signals.
In this post I will describe some essential steps and specifics of my setup.

This post will only interest you if you’re using a Mac. AFP (Apple Filing Protocol) is the protocol Macs use to share files over a network. This post will guide you through setting this up using Netatalk. It will also cover setting it up to be easily accessible without the IP address.
Latest versions of mosquitto (since 1.4) include the websockets interface, but the binary download available from the website does not. So you have to download the source code and build the packet your own, last you have to configure mosquitto to use websockets.
Node-RED provides a browser-based UI for creating flows of events and deploying them to its light-weight runtime. With built in node.js, it can be run at the edge of the network or in the cloud. The node package manager (npm) ecosystem can be used to easily extend the palette of nodes available, enabling connections to new devices and services.

MQTT is a Client Server publish/subscribe messaging transport protocol. It is light weight, open, simple, and designed so as to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and/or network bandwidth is at a premium.
