I've built many mechanical models out of Lego, so I wanted to try something really challenging. I built a clock out of Lego that kept reasonably good time. I thought it might be the only one of its kind, but after searching the web I found a few others. Now, several years later, there are many. One funny thing I noticed is that not only was I not alone in building clocks out of Lego, but many of the others felt they were the only ones doing this too! Here is a big index of all of the clocks and clock builders I've been able to find so far.
Please let me know if you have any additions for me!
Bill Toenjes just updated all of my broken links and added some new clocks (4/27/04)! Thank you very much for all the help, Bill!
