On April 4, 2023, I presented a webinar named [From the ESP8266 to the OpenShift cluster: discover what Red Hat can offer for the Edge computing!](https://events.redhat.com/profile/form/index.cfm?PKformID=0x1270056abcd&extIdCarryOver=true&sc_cid=701f2000000txokAAA) with three colleagues: [Adrien](https://www.linkedin.com/in/adrien-legros-78674a133/), [Florian](https://www.linkedin.com/in/florian-even/) and [Sébastien](https://www.linkedin.com/in/sebastien-lallemand/). |

This webinar showcases a lab that we built and delivered for the {{< internalLink path="/speaking/red-hat-tech-exchange-2023/index.md" >}}. |

## Lab description |
|
|
|
|
|
|
|
In this lab about Edge computing, participants stepped into the role of managing a parcel shipment hub using Red Hat products. |
|
|
|
The exercises revolved around the common and relatable theme of "shipment tracking". |
|
|
|
|
|
|
|
Participants helped a fictious company, FSC (the **F**edora **S**hipping **C**ompany), set up its Edge computing infrastructure to support 10 warehouses and a central headquarter across EMEA. |
|
|
|
|
|
|
|

|
|
|
|
|
|
|
During the lab, attendees set up and deployed all essential components to create a connected parcel tracking system. |
|
|
|
They began by configuring devices, using the Arduino IDE and an [ESP8266](https://en.wikipedia.org/wiki/ESP8266), to read the parcel tracking number using RFIDs, which is then transmitted over Wi-Fi to an MQTT broker. |
|
|
|
Using Camel-K, the data was transformed into actionable events and sent to a central headquarter system for real-time reporting. |
|
|
|
|
|
|
|

|
|
|
|
|
|
|
Meanwhile, at the headquarter level, a dedicated application visually mapped the movement of parcels as they traveled between hubs, creating an interactive, dynamic view of the entire shipment process. |

|
|
|
|
|
|
|
To make the lab as much fun and interactive as possible, the participants had to work in teams of six people: |
|
|
|
|
|
|
|
- Two people working in pair programming were setting up the firmware of the ESP8266 microcontrollers to scan **incoming** parcels, along with the MQTT broker and the **incoming** topic. |
|
|
|
- Two people, *ditto*, were setting up the firmware of the ESP8266 microcontrollers to scan **outgoing** parcels, along with the MQTT broker and the **outgoing** topic. |
|
|
|
- Two people, *ditto*, were setting up the Camel-K routes and the Kafka broker. |
|
|
|
|
|
|
|
{{< attachedFigure src="slide-principle.png" >}} |
|
|
|
|
|
|
|
Then, once everything properly setup, a participant scan a parcel in the **Athens** warehouse and then in the **Paris** warehouse and in realtime a parcel would move from **Athens** to **Paris** on the map displayed on the screen. |
|

## Bill of materials |
|
|
|
|
|
|
|
This lab makes use of physical devices to scan the RFID tags of parcels, so if you plan to replicate this setup, you might need the following Bill of Materials. |
|
|
|
|
|
|
|
| # of items | Description | Unit price | |
|
|
|
|------------|--------------------------------------------------------------|-------------| |
|
|
|
| 1 | 2.4 GHz Access Point, compatible with OpenWRT (TL-WR802N V4) | 27 € | |
|
|
|
| 25 | Wemos D1 mini ESP8266 development kit | 6,99 € | |
|
|
|
| 25 | RC522 RFID reader kit (each kit has 2 RFID tags included) | 3,40 € | |
|
|
|
| 25 | USB A - Micro USB cable | 0,99 € | |
|
|
|
| | **Total** | **~ 310 €** | |
|
|
|
|
|
|
|
The ESP8266 and RC522 RFID reader have to be soldered on together. |
|
|
|
Rince and repeat for the 25 units! |
|
|
|
For each unit, it took me from one hour down to 20 minutes once properly trained. |
|
|
|
Quite a time consuming task! |
