This is another blog about Raspberry PI, and today I want to show how I did a simple Kafka cluster demo using the Inky pHAT. It’s kind of a continuation from my previous blog, Kafka at the edge with Raspberry PI<\/a>.<\/p>\n If you’re not familiar with Kafka, I suggest you have a look at my previous post What is Kafka?<\/a> before, and you can have a look at how I created the Kafka cluster here<\/a>.<\/p>\n The Inky pHAT is an add-on board for Raspberry Pi, that has a low-energy, high-falutin, electronic paper (ePaper \/ eInk \/ EPD) display for your Pi, in three different color schemes: red\/black\/white, yellow\/black\/white, and black\/white. Real-Time Locating System (RTLS) enables identifying and tracking the location of objects or people in real-time. It is used everywhere in transportation and logistics across industries.<\/p>\n Use Cases<\/b><\/p>\n This is not an exhaustive list.<\/p>\n A postmodern RTLS requires an open architecture and high scalability and of course, the implementations can rely on Kafka.<\/p>\n A simple Raspberry Pi Kafka example where I can use one node to get the open Dublin Bus data and display it in real-time on the other node using Inky phat.<\/p>\n For the producer part, you can use my Micronaut Sense hat example as a start point and just change to use Dublin Bus data instead. You can get the full Micronaut Kafka Producer code on my GitHub<\/a>.<\/p>\n https:\/\/data.smartdublin.ie\/dataset\/gtfs-r-real-time-passenger-information<\/a> For the consumer part, you can use my Quarkus example. You can get the full Quarkusl Kafka Consumer code on my GitHub<\/a>.<\/p>\n Results<\/b><\/p>\n Raspberry PI + fun — Igor De Souza (@Igfasouza) August 23, 2020<\/a><\/p><\/blockquote>\n<\/div>\n Kafka can be deployed as a single broker in a vehicle and a global Kafka infrastructure can spread to multiple cloud providers, regions, countries, or even continents and integrate with tens or hundreds of factories or other edge locations.<\/p>\n Curiosity<\/b><\/p>\n 1- Dublin bus is already using an e-ink display to show bus stop data.<\/p>\n 2- I did a demo for real-time data from connected vehicles some time ago.<\/p>\n Streaming demo, Lambda and Kappa architecture.<\/p>\n Real time data from connect vehicles.<\/p>\n Flume + OCI Streaming + Spark + NoSQL + Spring boot dashboard#oracle<\/a> #oci<\/a> pic.twitter.com\/GTUem3CWWH<\/a><\/p>\n — Igor De Souza (@Igfasouza) September 5, 2019<\/a><\/p><\/blockquote>\n<\/div>\n 3- I won a prize at Europe’s First government-funded Blockchain Hackathon with the idea of an app to track medical devices combining Kafka and BlockChain.<\/p>\n Europe's First government funded Blockchain Hackathon! #ireland<\/a> — Igor De Souza (@Igfasouza) January 26, 2019<\/a><\/p><\/blockquote>\n<\/div>\n https:\/\/towardsdatascience.com\/tracking-nyc-citi-bike-real-time-utilization-using-kafka-streams-1c0ea9e24e79<\/a><\/p>\n https:\/\/eng.lyft.com\/a-new-real-time-map-matching-algorithm-at-lyft-da593ab7b006<\/a><\/p>\n https:\/\/github.com\/ds4es\/real-time-units-gps-tracking<\/a><\/p>\n","protected":false},"excerpt":{"rendered":" How\u2019s the craic? 2021\/03\/03 This is another blog about Raspberry PI, and today I want to show how I did a simple Kafka cluster demo using the Inky pHAT.
