Sorry for the late update; I've been off the site for several months.
I never did get around to building more clocks in a series, and I no longer have any desire to build one clock per week now that the Ahmed thing is over, so I'm declaring this project complete. However, I will build more devices that tell time at some point in the future. But those will be separate projects.
I'm also thinking about entering this in the /r/DIYelectronics first monthly contest, for an unconventional clock.
