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.

An old Bodet BT 6.30 flip clock gets a second chance! What started as a cheap find on a classifieds site turned out to be a real DIY adventure. A scratched front, a broken logo, and charred components on the inside. I'll show you how I not only visually restored this slave clock but also brought it into the 21st century with an ESP32.
