I came up with a Lego implementation of a clock striking device that strikes
a bell to indicate the hour. At 1:00, it rings the bell once, at 2:00 it
rings the bell twice, etc. It is powered by a weight, and it will play the
sequence of hours over and over as long as it has enough string. It isn't
connected to my clock yet, but I am working on it. It has a trigger that
needs to be tripped on the hour, and it does the rest. I have a photo

and an AVI movie of it in action

The secret to making it work was to use Lego conveyor links mixed with
regular chain links to rig up a counting belt. You can use Lego links like a
punch-tape to sequence complicated automata. If you had several sprockets
with several link-belts, you could play chimes in a musical order, and stuff
like that.

| Nice work. Your use of the differential is really clever. -- Bob Fay rfay@we.mediaone.net The Shop (URL) Silverstein" <amnon@best.com> wrote in message news:G5182G.B1I@lugnet.com... (...) strikes (...) (24 years ago, 4-Dec-00, to lugnet.technic)
