To take a plain old timepiece or clock and make it run backwards and fit it into a really cool clock face to make your own customized clock you can hang proudly ,because you made it yourself.
How cool is it?
well, its pretty cool take it from me i had this clock in my dorm room for a year and everyone who has seen it has asked me how to make one or asked me to make one for them. (like hell i'll make one for you...).
Has this been done before?
yep. there is another Instructable for this which is also very detailed if you want another source to clear your doubts. link: https://www.instructables.com/id/Reverse_Clock_1/ By crazypoop.
But i made the reverse clock 4 years ago for my science project about the working of a clock.
Why would you want to make a clock that runs backwards?
Because its cool.
Step 1: Things You'll Need.
1. You'll need a quartz movement . i.e the part of the clock that actually has the mechanics and the hands. I took mine from an old clock that i had lying around which i never used. you can also buy one its pretty cheap.
2. Carboard, Paper and pens to make the clock face and to make the numbers on it.
3. Extremely optional is a Digital camera to record each step because the Instructable involves opening up the clock and removing the cogs so you might want to record each step when you put the parts back in.
That's all . So, without further ado lets make a creepy backwards running clock.
Step 2: Opening the Clock.
Remove the hands and the battery from the clock movement. Open up the outer cover and make sure to take a picture or spend a few seconds to note the positions of the cogs because you'll need it when you are putting it back together.
What you need to do is reverse the polarity of the electro magnet in the motor that runs the clock. you do that by reversing the electromagnet itself . The 'U' shaped metallic thing with the coil wrapped around it is the electromagnet.( see in the next picture.).
proceed to next step.
Step 3: Revrsing the Polarity of the Electromagnet.
Remove the electromagnet and DO NOT break the coil's connection with the clock or you're screwed.
remove the u shaped metal from inside the coil and flip it 180 degrees. and insert it again into the coil. and put the electromagnet into the clock. I know this step might seem hastily explained but theres simply no other way to put it. See the pictures and i am ready to answer your queries about any step as well.
(NOTE: You might have to remove the tiny little plastic things that keep the magnet in place because they might cause a problem after you reverse the magnet.)
And now for putting it all back together......
Step 4: Putting It Back Together.
trust me if the cogs are turning they are turning the way you want them to be turning. If they are not turning, now that's when you have a problem.
Step 5: Making the Clock Face.
try searching for 'Whatever clock' on google.
Just cut out a sturdy cardboard into a square and stick a paper of color you want. Then make the design onto the paper, cut the right sized hole dead center and insert the clock movement from behind. Or you could also design the clock face on the computer and print it out.
Now put the hands of the clock in the right place and insert the battery to see if they move anti-clockwise. They will !!!!
see next step as well please.
Step 6: And Finally...
If you know any way to do the same thing more easily I'd like to know about it, or if you liked this instructable. Even if you didn't like this instructable I'd like to hear about it so feel free to criticize.
I also made one for my GF with the word Meh. instead on Whatever and if you had other cool ideas about the clock face tell me about them.
