Technik hilft uns, die Natur besser zu verstehen – z. B. beim Urban Farming auf dem Balkon. Wichtig ist mir dabei die Hoheit über unsere Daten. 🌱

Im neuen Workshop zeige ich, wie man Bodenfeuchte-Messung mit Arduino und Docker realisiert, ganz ohne Public Cloud. Ein Schritt zu mehr digitaler Souveränität.

Hier geht's zum Mitmach-Wissen:

I've finally got a decent method for monitoring my water levels.

Remote senors are built on HeltecV3 boards with ultrasonic measurement distance from water surface. Solar powered and waterproof, battery lasts 10 days without charge, panel recharges in 3 hours of direct sun.

Data is transmitted by LoRa to a Heltec monitor that has WiFi connection and uploads to a LAN server.

The webapp allows for config changes on the sensor. Config changes are staged, applied and verified.

Built with #Jetbrains Clion, #Arduino IDE, #Claude and hosted on #linux, in #Puertorico #WEPA

Forgetfulino Puts Back Up Of Source Inside The Binary

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate thin…

Review of Open Nextion ESP32-S3-based HMI displays with the Arduino IDE and the ESP-IDF framework

https://fed.brid.gy/r/https://www.cnx-software.com/2026/03/18/review-open-nextion-esp32-s3-based-hmi-displays-with-the-arduino-ide-and-the-esp-idf-framework/

Review of Open Nextion ESP32-S3-based HMI displays with the Arduino IDE and the ESP-IDF framework

ITEAD has sent us samples of the Open Nextion ONX3248G035 and ONX2432G028 ESP32-S3 HMI displays for review. Open Nextion is a new product line that differs from the original Nextion HMI family, which relies on the Nextion Editor for UI design and UART communication for control. Instead, the Open Nextion features an ESP32-S3 wireless microcontroller handling logic processing, display control, and wireless connectivity, all in one integrated package. ITEAD fully supports the ESP-IDF framework and the Arduino IDE with LVGL graphics library support. The ONX3248G035 model features a 3.5-inch screen, while the ONX2432G028 variant has a 2.8-inch screen. The Open Nextion HMI wireless displays also take accessories such as a dual-microphone array, a speaker, and an I/Os adapter. The new Open Nextion product line is especially well-suited to embedded developers/makers who want an all-in-one board with HMI and wireless capabilities, IoT terminal and Smart HMI panel prototyping, students interested in
