The Bodet BT 6.37 is considered the Holy Grail among flip clocks. In this report, I show the restoration of two of these models, from the repair of an oxidized motor and a defective flap to the modern control via an ESP32 slave clock controller.

Complete Deep Learning tutorial for real time digit recognition on the ESP32 P4: Following the creation of custom MNIST training data, the PyTorch training and the Int8 quantization via ESP PPQ, the finished model evaluates drawn digits live on a touch display as a bar chart.

Review of the Waveshare ESP32-P4-Module-DEV-KIT-C featuring a large 10.1" display in a compact Raspberry Pi form factor. Includes a detailed step-by-step guide for LVGL GUI development using ESP-IDF and pure Espressif components: from MIPI-DSI initialization and touch integration to the final application.

A compact slave clock controller with ESP32-C3 and DRV8871 H-bridge. The circuit synchronizes automatically via Wi-Fi and NTP, has a battery backup for power failures, and costs only a few euros to manufacture. Complete instructions with circuit diagram, components, and finished code.

The new CrowPanel Advance 7" uses the ESP32-P4 for native MIPI-DSI interfaces. However, the test reveals not only high computing power but also a design problem with the co-processor: Why the hardware architecture of the ESP32-C6 becomes a dead end for ESP-NOW and for whom the board is still worthwhile.

A lightweight library for the ESP32 for dynamic configuration of Wi-Fi access data. Implements a web server & captive portal for user-friendly provisioning. This allows the SSID, password and time zone to be transferred to the ESP32 without a special app.

This guide will show you how to install the Lyrion Music Server (formerly Logitech Media Server) on a Raspberry Pi 5. This version of the server uses an NVMe SSD instead of the standard SD card, making it extremely powerful. I have also housed it in a retro-style case.

The ESP32 weather station is now over a year old. So it's high time for an update. I have therefore spent the last few weeks developing a completely improved version of the weather station. I would like to present the changes to you in this article.

How can you control higher loads such as LED strips with the ESP32 when a single GPIO pin can only deliver a few milliamps at 3.3 V? In this article, I take a practical look at different transistor solutions for switching higher currents with the ESP32. I compare a Darlington transistor with three MOSFETs and show, which types are suitable for logic-level control.

The ESP32-S3 7 inch display from Sunton is one of the few boards that combines a modern microcontroller with a comparatively large display. I will show you how to get it up and running with just a few steps.
