The Propeller Clock from HDD motor
Awesome, I have seen many Propeller Clock projects but I rather like this. It made of the rotating 33 LEDs line and the HDD motor. Sory, no details about making just video only. Guarantee with five stars from 443 rating(on April 18,2009).

Email Clock
Tom Igoe writes:
Like many people, I have a lot of anxiety about my email inbox. With every kilobyte that comes in, another minute of my life disappears, time I could spend doing things I enjoy more than checking email. But I can’t stop checking my email compulsively while I’m working, and email programs make it even easier to feed my compulsion. So I decided to embody my anxiety in a device that would compulsively check my email for me, and worry over the amount continually coming in, so I wouldn’t have to.

1Hz Clock Generator using PIC12F675
The concept is using 32.768kHz crystal as a clock for the PIC. Therefor, the internal instruction clock is 32768/4 = 8192 Hz. By using the 16 bit Timer1 to count the instruction clock cycles, the interrupt will occur every 8 second. This period can be reduced by setting initial value of the Timer1 (TMR1H:TMR1L). [more]

Timebase generator
Timebase is the heart of every clock project.

The hard part to build a clock is the one-second generator. I build 2 Digital clocks before and took many hours to calibrate it and get exactly one second. With this circuit, you can get one minute or one second without problems, you can use one of these xtals: 32.768Khz, 1 Mhz, 4 Mhz or 10Mhz.

Classic LED 7-Segment Displays
Here is a simple digital clock using classic LED 7-Segment Displays from vintage calculators and vintage led watches. punkky writes:
I have made simple clocks using these displays and PIC16F887. The real thing looks much better than the photo. The displays are bright red and sun light viewable. Very COOL!!! They are on my computer desk and I love to see them very often.
