When was the last update of the diode clock?
This project was created on 05/12/2016 and last updated 2 years ago. The Diode Clock is the first large-scale test of DDL, a universal digital logic family using only 1N4148 and 1N4007 diodes as switching elements.
What kind of diodes are used in a clock?
The clock is a six-digit HH:MM:SS timepiece using only DDL gates (1N4148/1N4007 diodes) for the logic and display functions (the LEDs are also diodes, of course). The power supplies and currently the crystal-oscillator timebase use more traditional circuits, including transistors and ICs. You can see the clock working in this brief video:

What kind of diodes are used in DDL?
The Diode Clock is the first large-scale test of DDL, a universal digital logic family using only 1N4148 and 1N4007 diodes as switching elements. While simple AND/OR gates have long been constructed using diodes, and exotic tunnel diodes have previously been used for arbitrary logic, DDL uses only common diodes.

How does a 7 segment digital clock work?
The display is paired with IC 4026 which is designed for driving 7 segment displays. Each IC 4026 is controlled by Arduino. This clock has beep alert function, which beeps every beginning of the hour, giving a rough idea about time without looking at the clock. This clock does not have alarm function.
