\nThere are plenty of cool ESP32 products out there, and they all achieve something different. However, some of them have a simple job: take something simple and make it look really amazing. For example, why not take a peek into what a Wi-Fi connection is doing and show its traffic as a beautiful light show?
Well, that’s exactly what one person did with their ESP32. With some tinkering, they turned their internet usage into a lovely little setpiece. And the best bit is, you can make one yourself if you like.

And a very pretty one at that<\/p>\n

Over on the ESP32 subreddit, user AHTMGC discussed a new project they had finished. In the post, they explain that they watched one of RootKid’s videos titled \u00ab\u00a0I built a light that can see radio waves\u00a0\u00bb, which uses a Raspberry Pi Zero to visually represent Wi-Fi traffic. They were inspired to see if they could achieve the same thing using an ESP32, so they got to work:
You can see a video of it in action in the video above. The way it moves and shifts colors gives me a very aurora-like feeling to it, and I definitely wouldn’t mind having that hanging on my wall at all times. If you want to give it a go yourself, you can check out the project’s code over on GitHub, including a full list of materials with links to where you can buy them, alongside a full guide on wiring it up and getting the software set up.
