Clock

Hello, I recently acquired this clock (photos attached), after googling around, i think it is some type of network synced clock.. It has a green plastic cover with a transparent front side, the cover has no buttons at all ( it s not a radio clock). the only input output are those 4 pins in the 4th photo. I think it can be a good project,  maybe box it in wood, but i have no idea how to make it work. can you help :)? thanks

Clock in a jar

Here's a cool concept made by Oren Hetzroni. It's a clock in a jar where the hands move around the inside of the glass. Reading it is a little tricky, but if you match up the big and little hands with the numbers you can figure it out. Remaking this one is super easy. Just put the movement inside the lid and bend the hands at a right angle so they move around the side. jar via core77

Talking Clock

Hi Everybody, I'm new to the forum of inscrutables, but I've been bored at work recently and been thinking of things to brighten the place up. I've come up with an idea, but have very limited technical skills, if somebody could just point me in the right direction so that I could start this project I would be really appreciative and would post up pictures and videos of the final product. Idea: Essentially, I work at a pool where the lifeguards rotate every 15 mins, which they forget to do OFTEN! Me and a few others have decided to make a clock to replace our current one that would, every 15 mins make a noise, or say "rotate" to remind them to rotate on time. It would also be fun if we could have several different voices saying "rotate" of different employees. I'm pretty sure this can be done because I've seen clocks that make bird chirping noises, But I can't figure out how they work. Any help would be awesome, I really want to learn new things, which I think is everybody's reason for being on instructables anyway. Thanks, George

CLOCKS!!! how to make a.... very powerful clock?

Hey, I'm new on here but realllyyy need some help in this as I have a limited technological background. Basically I have a project in which have two digital displays, each one displaying either the time, in minutes or the hour (two digits per display). Now what I want to do with these is effectively attach these on to the hands of an analogue clock, so that when the hands spin round, the time is displayed. For example when the minutes hand is at the quarter past mark, the display will read 15 and when the hour hand is at the bottom the other display will read 06. So I have the designs ready for this clock (including counterweights and whatnot) but I just need a very powerful clock movement, or gearing system that will enable me to turn a couple of heavy clock hands, I have seen online you can but high torque movements which at the moment is my best bet, but i cant imagine it will work very well to be honest. I would really appreciate any response or something to point in the right direction as I'm very open minded and if the issue is solved, I will be sure to put up instructions on how this clock was made. Thanks for reading. Josh

The new "face" of clocks.

Two men in their bedroom, with time on their hands... Building clocks. An elegant, simple new design of clock is being produced by two entrepreneurs in a bedroom. The spiral face rotates, clockwise, every 12 hours, slowly winding a small ball up the coiled face.  At the twelfth hour, the ball drops into the centre of the face and back to the beginning. The clock is an art piece, costing hundred of pounds, but I bet you could build your own version from off-the-shelf parts or a recycled clock. After all, the prototype was knocked together from beer cans and gaffa tape... BBC video article. Aspiral website. Advertising video: Oddly philosophical video:

World Clock Project

The World Clock Project takes a creative look at time. By taking clocks from around the world they're mixing time-zones and still keeping a relative view. It's thought provocative to think about time and how important it is to the human experience. Time is our most valuable currency, it's really the only thing we have. So it's interesting to see how important keeping track of it has been, we've been using Obelisks as sundials for over 5000 years, some of the most ancient artifacts from egypt were built to keep track of time.It's good to see that The World Clock Project is keeping time on our minds. Give it a shot, upload your clock and let us know where it is[http://world clock project upload http://worldclockproject.org/]-bg

spiral clock hands

I want to make a desk clock as a small project for myself. What I am looking to create is a slim clock with a spiral hour hand. The time would be told by graduated marks on the back-plate i.e. as the hour hand turns, the spiral increases and the correct hour is reached by the spiral, hard to explain, can't upload a photo as instructable server maintenance is under-way, hopefully I'll be able to upload the brief sketch I did in paint which might help!! What I am looking for is suggestions on a material which could be used for the hand, it needs to be thin so as to make it as easy as possible to tell the time and also strong enough not to distort under its own weight. Haven't decided whether it's going to be a normally incrementing spiral or a Fibonacci spiral (or similar logarithmic spiral)

Hacking An Alarm Clock

My sister (yes, the one for whom I made earrings) wants me to modify an alarm clock to run a small electronic device when it goes off. Preliminary research has given me two methods:1) A digital clock with a 555 timer circuitIn this setup, a 555 timer circuit is used to translate the signal to an alarm speaker/piezo disk into a relay. When the clock goes off, the relay clicks, and any electrical device that is run through the relay has power.2) An analog clock with a transistor amplifierIn this version, the analog clock seems to just have a straight DC output to the alarm. The transistor is used to amplify the DC to drive the motor of a fire bell.Which of these would be easier to implement? The device I am supposed to use runs off of 3VDC, so I was just going to run the power line through the relay or through the transformer.

Digital clock hack

I've been trying to do more DIY stuff recently, so I figured I would start out with an easy project. Basically, I was wondering if it is possible to modify a standard digital clock so it could display different messages through an lcd display based on the current time. Since most clocks have an alarm feature, I thought this would be pretty easy to do, but then again I could be completely wrong. I know how to solder and such, so I shouldn't have too many technical problems if I get a push in the right direction. Also, I know how to do a bit of coding, and I'm good at adapting so I'm sure I could find out some way to make this work. Any help is much appreciated.

Customized Alarm Clock

What I want to do is this, -get rid of my alarms stupid sounds -insert a custom sound -do it cheap -and make it small enough I can still put it in a custom casing (the casing is the easy part, I'll have no issue making that.) I have looked around and have seen several ways to hack alarm clocks but I can't see how any of them would help me out with this particular problem. The way I see it I will probably need to rewire the clock so that it sends power to an external device when the speakers are supposed to go off. The only other way I can think of is having a small computer with one of those pre-programmed clocks but that would be more expensive than buying the sound recording clocks and a bigger pain to fit into the casing. I also think I heard someone talk about making homemade circuits, I don't know if that would work at all but it's worth mentioning. I would like to be able to find easy to follow instructions that are CLEAR and not super complicated. Any help would be appreciated! BTW, yes, I have looked at the sound recording clocks online and they all look like crap or are way to expensive to bother with.

YY:DDD:HH:MM:SS Countup Clock

I was looking to make a countup clock that would be able to count off time in seconds, minutes, hours, days, and years using seven segment displays. I have yet to be able to find an instructable like this. I imagine it would be very similar to a normal clock; however I do not know enough about electronics to be able to modify the standard clock instructables to be able to make my own.  The only way I know to do this with the knowledge I currently have is to make a mini PC and that would be cost prohibitive as well as overpowered.   The idea came up because I have my one year anniversary approaching and I figured it would be neat to have a clock whose sole purpose is to give an exact time count of being married.  I played around with the idea of having the clock play a song or display something any time a new year was added, but I figured for now to just stick to the basics.   If anyone knows of an instructable that fits this idea or is willing to make one/point me in the right direction here, that would be fantastic.
