This last week I attended VMware Explore 2024 in Barcelona. While at was at the conference, I had a small ESP32 board with an external antenna in my backpack, connected to a powerbank. The sole purpose of this little device, was to provide some fun random WiFI SSID’s, and to see if anyone actually connected to it.

All it did was to cycle through all the lyrics of Rick Astley - Never Gonna Give You Up, and if someone connected to it, show a captive portal that had an ASCII drawing of Rick Astley on it, and the following text:
You can blame this on @h0bbel
Have fun, be excellent!
It then logged the connection in a logfile om the ESP32 itself. No client details were logged, only that a connection was made and a timestamp based on milliseconds since the ESP32 was powered on.
Now, after running it from Monday to Wednesday at the Fira, the results are in, and all in all there were 63 connections made to my little device. Day 1 had 33 connections, day two had 25 and the last day only 5.
Make of that what you will, but obviously I did get to Rickroll someone at the conference! If you were one of them, reach out — I’d love to hear from you!
