Clock

I wanted to build a clock with hours, minutes and seconds. I had to :

- make a specific gearbox to make reduction for minutes and hour.
- get a concentric transmission with three axes (hard to make !).

I use Mindstorms RCX with a position detector to get a motor revolution each second.

For the moment, I don't have good photos of this model, still under construction...
It's quite hard to get precise clock with RCX : it seems that it's internal clock isn't very precise.
It's also quite hard to set manually the current time...

I still have to work on this project.
