You can add a real-time-clock circuit if you want it precise. With all this room to expand, you can get it built and running in a weekend for a few bucks. And that makes it the perfect “hello ...

The electronics are relatively simple. [Aaron] decided to ... tape and hot glue to prevent any short circuits. The end result is an elegant binary clock that any geek would be proud of.

Stepper-motor controllers can be simple (Figure 1), but they require a variable ... with 0.1-Hz resolution when you operate it with a 25-MHz MCLK (master clock). In addition, the circuit can easily ...

The simplified algorithm allows integration in smaller CPLDs or FPGAs that lack a DCM (Figure 1). Figure 1 A clock-recovery circuit in an FPGA recovers data in a 1.5-Mbps data stream. The algorithm ...
