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.

With the ESP32-C5, Espressif is bringing dual-band Wi-Fi (2.4 & 5 GHz) to a microcontroller for the first time. Espressif kindly sent me two pre-production models of the ESP32-C5-DevKitC-1 development board. I measured how the new microcontroller performs in practical tests.

40 years ago, I soldered together the mc-68000 homebrew computer. After 35 years in the basement, I am now trying to get the computer running again. I don't know yet if I will be successful, but it's an exciting journey into the past.

The clock has been running for quite a while now without any problems. However, one small thing still bothers me. The Hall sensors tend to oscillate. Therefore, I have redesigned the electronics from scratch.
