![Offline Map Viewer with ESP32 and Round Display
This is a small project I put together to show local maps on a 4-inch round display using an ESP32. The map tiles are stored on an SD card, so it works without Wi-Fi.
It’s not meant to replace your phone — it’s just a fun way to learn and experiment. The project uses LVGL to draw map tiles, supports touch scrolling, and lets you adjust the zoom level. As you move the map, the latitude and longitude at the center update in real time.
The workflow is straightforward:
- Download map tiles with an offline map downloader.
- Convert them into RGB565 binaries for LVGL.
- Load them from the SD card inside an ESP-IDF project.
I also published a map_tiles component to the ESP registry to make it easier for others to try.
This is just a hobby project, but it could be a starting point for other ideas like offline GPS gadgets or simple map-based dashboards.

![My Air Quality Sensor, LVGL 9, [Ep.06] Draw IKEA UI, #ikea #airquality #esp32
I made a similar version of IKEAs air quality sensor, VINDSTYRKA, using ESP32 and an environmental sensor.
When studying UI/UX, I think it is essential to create code yourself. Through this, you can become familiar with what widgets to use and how to create and apply styles. In this project, Ill first complete the UI using LVGL, and in the next project, Ill explain how to update the screen by reading the necessary data from the sensor. Thank you.

![This Tiny ESP32 Device Makes HOLOGRAMS?! (Holoneo Review)
Today I’m checking out the Holoneo Air Imaging Display—an ESP32-powered gadget that creates a surprisingly convincing floating 3D effect. I test its hologram visuals, try out its gesture-based UI, connect it as a Bluetooth speaker, and even play custom animations through its media player. Plus, I tried tracking the gestures with a Leap Motion… and the results were interesting. If you love futuristic displays, hologram projects, or cool desk tech, this device might be your next obsession.

I test real-time vision capabilities using Gemma 3 4B—the sweet spot for memory efficiency, speed, and accuracy on this hardware. I evaluate Scene Description, Object Detection, Activity Recognition, Safety Monitoring, and OCR text extraction using both an iPhone and a low-cost ESP32-S3 camera module via RTSP.

![LVGL Tutorial with ESP32, We can understand better and faster through LVGL Examples #LVGL #UI
If youre new to LVGL, you may not know where to start. Personally, I recommend looking at the example code provided by LVGL. It provides many examples, from Hello World to complex charts.
When I first tried LVGL (littleGL at the time), there wasnt much information. There was only documentation and examples they provided. It was great and I could learn a lot from them.
Anyway, please take a look at this as it covers all the basic and essential parts.
