For the ESP32-2432S028R Cheap Yellow Display: live conditions and forecasts from your choice of 20 weather data providers, on-device history logging and trend graphs, sunrise/sunset and moon phase, configurable alerts, and a built-in web portal for setup — no companion app or cloud account required.

ESP32-S3 Touch AMOLED 1.75C development board. Over four evenings, it somehow turned into a surprisingly nice little thingy.

It was very much a vibe-coding project. I guided some visuals, and forced optimization implementation decisions: how the display buffers and PSRAM should be used, which regions should be redrawn, how assets should be cached, and how animation should remain separate from slower network updates.

Getting beyond a basic mockup was a large part of the work: smooth radar and aircraft animation, partial screen updates, cached maps and imagery, and avoiding expensive full-screen redraws on the 466 × 466 gorgeous AMOLED.

It currently includes:

• Live nearby-aircraft radar with type-specific icons and detailed views
• Selected-flight tracking with world-map and custom 6-to-12 projections
• Weather, forecast, and animated weather radar
• GMT watch and world clock
• Solar-system, lunar-phase, and live ISS views
• NASA, Roscosmos, SpaceX crewed and Starship launch tracking
• Automatic Dock Mode
• A swift macOS companion app. Mainly for pre-render of the maps with different projection and to supply the list of flights to track.

There are still things to polish, but I’m amazed by how much this little ESP32-S3 can handle when the rendering pipeline is designed carefully.

Source code is not yet public but I may do it sometime in the future if people are interested.

UPDATE:

The board: https://docs.waveshare.com/ESP32-S3-Touch-AMOLED-1.75C (got from AE for ~$40 i think amazon also has them). Mainly ordered due to OLED.
The dock: https://a.co/d/012B5Kl2

I used 3 services for tracking in cascade: open sky -> airlabs (when open sky not providing enough info, requires API key but free tier seems to be enough for my use case) and flightaware for specific flight tracking (same as airlabs, requires API key but has free tier).

I will make the code public soon since people are interested, but current implementation does require a mac, since the initial setup is done through mac companion app. I'm not planing to change that since that was my preferred route.

Auto-detects ILI9341 vs ST7789, walks you through touch calibration and orientation, tests every peripheral (SD, RGB LED, speaker, WiFi...), and spits out a report saved to SD card. Built with Claude over a few days of back-and-forth. https://github.com/HenrysCat/ESP32-2432S028-CYD-Diagnostic-Tool

I tried a few already out there but just didnt like them, so I asked Codex to make one for me, it includes HamQSL propagation data, a greyline map, DX spots, Wi-Fi setup, and a local web settings page.

Open source and on GitHub hope you like it.

Now we can use things like esptool, it's disabled by default so go to about:config and switch dom.webserial.enabled to true.

What am I doing wrong? (apart from my incessant messing around which caused this) I managed to get a little overhang, so I thought I'll just pocket that face and it will be gone, but the whole thing dissapears.

Any ideas? Thanks all

I built a desktop flight-radar ornament with claude code!
Using an ESP32-S3 5" touch panel and ESPHome, it shows live aircraft over your location on an ATC-style radar scope  — complete with a rotating sweep and a glow as the beam passes each plane.

It does more than you'd expect:
1.Tap any aircraft for its origin/destination, altitude, speed & heading
2.Optional weather-radar (rain echo) overlay
3.Optional map outline overlay
4.Home Assistant integration — even works as an alarm clock that rings through your Wi-Fi speaker, with per-weekday scheduling
5.Everything configurable right on the touchscreen — no coding needed

Fully open-source (non-commercial). Code, docs and a demo video here

Just grab an off-the-shelf dev board, flash it, and you're good to go  Happy to answer questions!

Where the red arrow points, I want it to continue to a smooth join on the bottom layer.

Thanks

Forked from u/MatixYO's ESP32 Plane Radar and made with Codex, it shows AIS ship tracking info, an API key is needed from AISStream but it essentially works the same, the screen can get a little full when a wide range is selected especially in busy shipping lanes, full info and firmware in the GitHub https://github.com/HenrysCat/ESP32-Ship-Radar

Lets get this out of the way now, yes it was made with Codex

I wanted something cheap and accurate and this fits the bill, full logging of long term data to csv files on the SD card, built in web server to view data on local network so no external database or storage required.

Display can be switched to long term data with a swipe, CO2 temp & humidity can switched on the main screen with the boot button, full instructions and firmware can be found here https://github.com/HenrysCat/ESP32-CO2-Dashboard
