An interesting clock

Hello! I need a scheme for a fading clock. Please, has any body made something like this?  The idea - based on the fadenes on each number you can tell what time is it.  The GIF is very basic.

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

L.E.D. Wall clock idea

I saw this clock design the other day. It was a circle with the clock hands in the middle and unattacked to the clock there were dots around it to mark the hours. I want to improve this design by making the hour dots light up on their respective time for the whole hour. Maybe make them have a nice dimming transicion between the hour switch at the last second. I don't know much about programming L.E.D.s or what hardware I would need. Can somebody help me how to make this project?

The clock that erases itself

This clock has an eraser in the hour hand so it can erase the marks on the face of the clock as it goes along. Pretty good way of clearing the way for more events, but you might want to write down those notes somewhere else as well. Dry Erase Clock

A question about an instructable to do with clocks I saw a while back.

So if you go up to the search bar and type in the word 'clock', you get all sorts of results. Small clocks, big clocks, plastic clocks, metal clocks, Batman clocks, Skyrim clocks, everything under the sun. Bar one. The thing is, all these clocks are generic. They all are mostly the same. A standard circle with hands and the hands marching round the clock in circles. I'm not saying that this is bad, I'm just saying that seeing the same thing over and over and over gets very boring for me. So when I saw a clock that was unique and different, it was like a dream come true. However, if I try to look for that particular clock again, I can't seem to find it. The clock in question acts similar to the linear clock, but is still circular (hypocrite). Looks sort of like this:                  | ________\|/________ |________________|      |___________|         |________| The top row shows the seconds, the second row the minutes and the last the hours. Essentially, the hours and minutes and seconds all turn while the actual base stays still. The numbers are along the rows and as they turn, the arrow points to what the time is. If anyone can find this instructable, I will be grateful. Otherwise, I will be forced to do this project without the help of any sort of instruction.

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:

Spiral Clocks tell time with ball

These clocks tell the time by the position of a ball that slowly spirals in to the center and then gets dropped back down to start all over again. Pretty clever. Also pretty hard to read, but it's certainly a conversation piece and a good inspiration for some other projects. Link

Turning AM/FM clock radio into just a radio?

Hey guys, I'm new to this forum and couldn't quite find the answer to my question.  I have a cheapo AM/FM clock radio and thought it would be a fun Sunday afternoon project to turn it into just a radio.  I don't need the clock/alarm function anymore (I use my phone) and my dog likes to have some noise around when I'm not home (TV is an option, but I hate leaving the screen on all day).  Currently, the radio only turns on when the clock is triggered by the set alarm time...and it only plays for a max of 60 minutes.   Should be easy, right?  I opened the clock and couldn't quite figure out what I'm looking at...

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

Clock Powah! (power)

Clock idea = out!any other idea for a higher torque clock-like motorhere's a very very brief photo of my idea. The light gray is the rotatingfood area and would be push by the dark gray (white out!) motor. the yellowthing is a hatch. It was just for me to write my thoughts down and I know the hand will run into the wall and everything. The sloped rectangleis a ramp on the inside so the food turbine will move spilling down theramp into the bowl. Also the big hand is actually the hour hand, I drewa small minute hand to show it was a clock, This has it worked so it willfeed every 12 hours and needs to be refilled every day.I don't really need any critique just answers for now '"

How To Use the Alarm from an Alarm Clock in Something Else?

I wanted to make an alarm type thingy, ad I want to use the alarm from an alarm clock. I don't know how though, I tried connecting a cell to the wires that were already on the alarm, but it won't work. I think it's one of those piezo-electric crystal thingies. And I know I have to have pressure on it to work. How exactly would I use it?

Intricate wooden clocks you can make yourself

This crazy clock is one of several designs that Clayton Boyer makes and sells the plans for on his site. It may look pretty fiendish, but according to him: "As far as skill level required, I would suspect that if one has the tools necessary that skill is not as important as perseverance. When I started building these, I had almost no skill whatsoever, but that always develops after getting a little sawdust into your lungs. These are not difficult to build, but they do take some time." Anyone want to try making one of these? I'd love to hear some thoughts from others who have tried it. Link via boingboing

An Alarm Clock Idea - No Lights, No Sound

I'm a pretty deep sleeper, and I don't wake up very fast in the mornings, which is bad since I ride the school bus to school. I set my alarm clock, with a high volume, but it still doesn't wake me very good. I've thought of trying to make an alarm that flashes a strobe light, something like a deaf person might use, but didn't think it would work very good. So, my idea now is to think of a way to make an alarm clock that gives pulsating shocks when it goes off. I have absolutely (well, 99%) no idea how to connect it up, nor how to produce the shocks. I'm thinking a shock with high voltage, but low current, like static electricity. I figure that should wake me. Do y'all have any ideas, or better suggestions? Also, do you think that the shocks (if usable) would cause any dangerous effects on my health? Thanks!

Binary Arduino Alarm Clock HELP!

I am currently working on THIS INSTRUCTABLE: I have had to modify the libraries to work with IDE 1.0 and newer because this was written 5 years ago. I'm using a push button momentary switch instead of the capacitive sensor for the snooze button. I've got everything working except for the Alarm/snooze. For some reason, the speaker is constantly beeping a high, then low tone, as though the snooze button is being held down, even when I completely disconnect the snooze button from the clock. Can anyone give me any ideas how to fix this problem? Here is my modified button code: void update_buttons_state() {   hour_button_state    = digitalRead(hour_button_pin);   minute_button_state  = digitalRead(minute_button_pin);   setTime_button_state = digitalRead(setTime_button_pin);   setAlarm_button_state = digitalRead(setAlarm_button_pin);   snooze_button_state = digitalRead(snooze_button);     } // "INTERNAL" VARIABLES FOR BUTTONS FUNCTION: boolean first_time_hour = true;   // these are used to make sure that the hours boolean first_time_minute = true; // and minutes only is increased once every keypress. unsigned long snooze_button_timer; // used to keep track of how long the snooze button has                                    // been held down. when the button has been held down                                    // a certain amount of time, the alarm will be turned                                    // of completely. void buttons() {   // LOW == button pressed   // HIGH == button released   // (this is because pullup resistors is used)     // Decide if we should set time or alarm:   // (this also makes the display show the alarm time)   if(setAlarm_button_state==LOW) // LOW = Set time   {     hours_p = &alarm;_hours;     minutes_p = &alarm;_minutes;   } else if(setTime_button_state==LOW) // LOW = Set Alarm   {     hours_p = &hours;     minutes_p = &minutes;   }   // If hour button is pressed, increase hours:   if(hour_button_state==LOW && first_time_hour) // only increase the hours once   {                                             // every button press.     if(*hours_p < 23)       (*hours_p)++;     else       *hours_p = 0;         first_time_hour = false;          }   else if(hour_button_state==HIGH)   {     first_time_hour = true; // reset when button is released,   }                         // so that the next press will be registerd.     // If minute button is pressed, increase minutes:   if(minute_button_state==LOW && first_time_minute) // only increase the minutes   {                                                 // once every button press.     if(*minutes_p < 59)       (*minutes_p)++;     else       *minutes_p = 0;           first_time_minute = false;   }   else if(minute_button_state==HIGH)   {     first_time_minute = true; // reset when button is released,   }                           // so that the next press will be registerd.     if(snooze_button_state==LOW)   {     if(signal_on)     {       // set the time when the alarm signal will start again,       // this will give 10 minutes snooze:       if(minutes<50)       {         snooze_off_minutes = minutes+10;         snooze_off_hours = hours;       }       else       {         snooze_off_minutes = minutes - 50;         snooze_off_hours = hours + 1;       }       snooze_on = true;       signal_on = false;     }     // if the snooze button has been held down for more than 3 seconds turn off/on the alarm     if((millis() - snooze_button_timer) > 5000)     {       if(alarm_on) // if on, turn off       {         signal_on = false;         alarm_on = false;         snooze_on = false;         // play tone so the user know the alarm turned off:, 100);       }       else if(alarm_on==false) // if off, turn on       {         alarm_on = true;         // play tone so the user know the alarm turned off:, 100);       }       //reset the snooze button timer       snooze_button_timer=millis();     }       }   else   {     //reset the snooze button timer     snooze_button_timer=millis();   } }

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.

Sweep motion clock isn't silent anymore; what to do?

Hello all,  I hope to find some help here!  I own a sweep motion ''silent'' clock that was indeed silent until a few days ago. For unknown reason, it started to make a buzzing, motorized sound, as if I can hear the motor running inside. It's particularly noticeable when the clock is upright against the wall, not so much when its laying flat (which is totally useless) What to do ? Common sense with other clocks would be to lubricate the gears inside (sorry about my lack of clock-related vocabulary) but I don't know if I can do it with a sweep motion clock? Is it even the cause for this? Or the motor is just ruined? Also tried to insulate the back, helps a little but not so much. The reason I own a silent clock is that I am particularly sensitive to noises, it's driving me insane. Any help would be much appreciated.

Led Clock, Need Help. Using Arduino

I want to make a clock where there is a led blue or clear marking each hour around a circle, the led is on for that hour and then moves to the next led in the circle for the next hour.  pretty simple.  it will look kind of like an analog clock except without the hands.  for the minutes, i want the same leds as the hours to light up but since there will only be twelve, it will only be accurate within 5 minutes.  the minutes need to light up less bright that the hours so that i can differentiate between the two.  I have an arduino uno, breadboard, resistors and leds.  Please Help!!!

USB to Travel Clock Circuit Help :)

I've got this little black Oregon Scientific travel clock thing with a transparent screen. It was an old gadget of grandma's I found years ago. I was eying it, and I had a damn good idea for an Instructable-worthy project. I'd eventually like to run this off of USB power. Currently it has a little button-battery in it (Energizer 357, bout 1CM in diameter). I know USB out is an unsteady 5V, so I'd need a capacitor to regulate the current, I guess, and the necessary circuitry to adjust the voltage to whatever this little clock runs on. Any advice for such a novice?

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.
