Other people have pointed out the irony that clocks are almost always cyclical – mechanically and symbolically – already. However, it seems I’m the first to point out that time is not cyclical.

But yea, that is down right beautiful.

And it screams for a DIY version, with the wall unit made from some interesting found item. But add a minutes chain too just for grins :)

It’s a lovely clock, too.

1) Get a bike gear, and attach it to a 1 revolution per hour motor.

2) Make a bike chain chain with N X 12 links, where N is the number of teeth on the gear.

3) Attach a number every N links to the chain.

4) Hang chain from gear.

5) Profit!

Parts…

For a gear, go to a bike shop and see if you can pick up an old derailleur. Pull the gear off it. It’s probably just about right.

For bike chain, go talk to your friends at the bike shop. They will think what you’re doing is pretty cool. They can also make you a chain that’s custom length to do that “12 X N” number of links.

Then get a high torque clock motor. Google “high torque clock motor” and you’ll find a lot of cheap ones. If you’re going all out, see http://www.norkro.com/webpages/glodial.htm for serious big ass industrial clock motors.

Google for “metal letters” to find people selling metal.. er… letters. Or better yet for letters, get a local artist/metal worker to make some for you.

you’re welcome.

Yeah, because mounting digits on a plain old circle doesn’t signify the cyclical nature of time.

But I still like it.

Shmengie, it looks clockwise to me. The numbers and change goes around clockwise. If it went counter-clockwise the numbers would be decreasing.

At any rate, this begs to be DIY’d, perhaps with some means of better approximating minutes. A sweeping minute hand was suggested, as was a minute chain (somewhat complicated and certainly time consuming for the build … heh heh heh). Scoring minute lines along the casing to correspond with the top of the applicable hour numeral would work, as would scoring minute lines into the drive sprocket.

Maybe I’ll make this my winter break project …

We don’t watch it go ’round. We look at it for a moment, like any clock, the cog is essentially the hour hand.

They used a conventional clock drive and should have reversed it.

Discuss.

Why? The gear should go the way it always goes. Since there’s not another gear connected to the central gear, nothing gets reversed. The chain goes round-n-round, clockwise. As does the central gear.

Showing the cyclical nature of time isn’t much of a novelty for a clock. Clocks have been going in circles for about 1000 year?

Dammit! You are correct, sir or madam! The numbers should go clockwise. The motor direction is OK.

This clock needs a “minute hand” attached to the gear to sweep each hour. (I am assuming that each revolution of the gear is 1 hour.) This will also give a more solid clue as to “am I at the top or bottom of the hour?”

not so with this one. but I only wish I had $2300 to throw at a novelty clock.

Let’s see, clock internals ($5.00), bike chain ($20.00), brass numbers ($40.00), time to chemically weld or actually weld numbers to chain and glue a small sprocket to the clock internals and then adjust chain to go around sprocket once every 12 hours (4 hours aprox).

Total cost: $65.00 and 4 hours.

Price on website: $2338.00 + shipping.

Time: DIY!
