Here's a question...

[Arquibaldo]

how about building unusual or funny clocks?

Like the 24h clock used by the military (remember the movie "The Enemy Below"?) , or a clock that runs counter-clockwise. Or, better yet, a large
version of a "scrambled" watch I have seen somewhere selling for an
enormous amount of money: all the number 1-12 are on the dial, but in
a scrambled order...

I have been considering these projects for some time; they demand a small
microcontroller like an AVR, but this would be no problem (for me); what I
couldn´t figure yet is a simple, effective way of having two steppers moving
coaxial axes, for the hours and minutes - any ideas?

just do what clock makers have done for ages...mount one spindle through the other like a shaft within a pipe. drive each with a small timing gear of different diameters. seems simple like most hard things do???

I've seen the scrambled clock what would be cool would be to program the stepper to actually somehow tell the right time! good idea!

how about an egg-bot?

I did one, it was way cool. Motors were free from a floppy drive, stepper controller cost me $5 to build. Controller software was GBASIC. I want to eventually incorporate PenUp/PenDn functionality. Then it would rock.
