How to Build a 60 Second Timer

How to Build a 60 Second Timer

by russ_vin

If you want to make a timer, its easy. This timer can go for 60 seconds or less.

You first need a few common materials:

-a analog clock with a second hand (a small clock or something, but not a watch)
-wire
-a power source
-something to send the electricity to
-a nail

-before starting make sure the clock is off

1. Take your clock and at the 12 put the nail in but so that the top of the nail would get hit when the second hand comes around. Also make sure that a lower section of the nail is accessable.

2. Wrap some wire around the second hand, enough so that a connection would be made when the second hand comes in contact with the nail.

3. Attach a wire from the end of the second hand close the center of the clock to whatever is being set off. Make sure that the wire is connected to the wire wrapped around the second hand.

4. Put a wire between whatever is being set off to your power source.

5. Put a wire from the power source to the bottom of the nail (or to a part of the nail under or above where the second hand will make contact.

Now to set your timer:

1. Move the second hand to anywhere but touching the nail. If you put it to the 6 you will have 30 seconds. If you put it right after the 12 you will have 60. I would think you would understand.

2. Get ready to move away if this is some sort of bomb or if not then be ready to start whatever is going on.

3. Turn on the clock.

Or if you want to be a distance from your device just get a long length of wire.
