Hawkeye, the 3D-Printed Tourbillon Movement

Posted on by

As if building tiny mechanisms with dozens of moving parts that all need to mesh together perfectly to work weren’t enough, some clock and watchmakers like to put their horology on hard mode with tourbillon movements. Tourbillons add multiple axes to the typical gear trains in an attempt to eliminate errors caused by the influence of gravity — the movement essentially spins on gimbals while tick-tocking away.

It feels like tourbillons are too cool to lock inside timepieces meant for the ultra-rich. [Alduinien] agrees and democratized the mechanism with this 3D-printed tourbillon. Dubbed “Hawkeye,” [Alduinien]’s tourbillon is a masterpiece of …read more

The Tourbillon: Anti-Gravity for Watch Movements

Posted on by

Do you know what time it is? Chances are good that you used a computer or a cell phone to answer that question. The time on your phone is about as accurate as chronometry gets these days. That’s because cell networks are timed from satellites, which are in turn timed from atomic clocks. And these days, it may be that atomic clocks are the only clocks that matter.

Before this modern era of quartz and atomic accuracy, though, timepieces were mechanical. Clocks were driven by heavy weights that made them impractical for travel. It wasn’t until the mainspring-driven movement came …read more

Linear Clock Slows the Fugit of the Tempus

Posted on by

We feature a lot of clocks here on Hackaday, and lately most of them seem to be Nixie clocks. Not that there’s anything wrong with that, but every once in a while it’s nice to see something different. And this electromechanical rack and pinion clock is certainly different.

[JON-A-TRON] calls his clock a “perpetual clock,” perhaps in a nod to perpetual calendars. But in our opinion, all clocks are perpetual, so we’ll stick with “linear clock.” Whatever you call it, it’s pretty neat. The hour and minute indicators are laser cut and engraved plywood, each riding on a rack and …read more

A Clock Created with Conway’s Life

Posted on by

Conway’s life has to be the most enduring zero-player computer game in history. Four simple cellular automaton rules have been used to create amazing simulations since the 1970’s. The latest is an entire digital clock implemented in life. StackExchange user [dim] created this simulation in response to a challenge from [Joe Z]. We have to admit that we didn’t believe it at first, but you can run it yourself by importing [dim’s] gist to the online Javascript Conway’s Life Simulator. To say this is impressive would be an understatement. We don’t know exactly how long it took [dim] to build …read more

For Your Binge-Watching Pleasure: The Clickspring Clock Is Finally Complete

Posted on by

It took as long to make as it takes to gestate a human, but the Clickspring open-frame mechanical clock is finally complete. And the results are spectacular.

If you have even a passing interest in machining, you owe it to yourself to watch the entire 23 episode playlist. The level of craftsmanship that [Chris] displays in every episode, both in terms of the clock build and the production values of his videos is truly something to behold. The clock started as CAD prints glued to brass plates as templates for the scroll saw work that roughed out the frames and …read more
