Flayed Alarm Clock

Intro: Flayed Alarm Clock

It is just that a flayed alarm clock. I was tired of how it looked so I made into a functional art peace.

STEP 1: Flaying

I dont have a photo to show you but its straight forward. Just take the clock apart.Then lay the guts out flat and mount. I used Liquid Nails to glue it down.I know there are exposed wires but its not a toy .You can mount it on or in anything nonconductive.Also stabiles the power cord so it wount put stress on its soldered joints. This is more art than science but use common sense. Leave it unpluged untill after you have it mounted.

what does ground wires do i dont get it the look like as if it's just a freking wire that u can cut out

As long as everything goes well the ground pin is unnecessary, this is why older style plugs (and newer ones in low current or double insulated applications) don't have a round ground connector.

The ground is there as a safety precaution, so that if:
a) the live (hot) touches a piece of metal that it isn't supposed to, like the case that here has been flayed away, or
b) the neutral (return) wire touches the case *and* the load in the circuit the clock is plugged into is unbalanced
then the current will go through the case, down the ground line (which is attached to the case) and into the earth.

Without the ground conductor attached, if either (a) or (b) happened and someone touched the clock's case while it was happening they'd get lifted by mains power.

FYI: Ground Fault Circuit Interrupt (GFCI) plugs (like the ones that are usually in bathrooms with the "Test" and "Reset" buttons in the middle) go an extra step by monitoring the connections and if current begins to leak (i.e. go from hot/neutral to ground, like in the above example) it isolates the device, i.e. disconnects it from the mains. You would then have to hit the reset button to get the plug working again, but the shock you get would be so small and quick that you probably wouldn't even feel it.

uhm,... it's not exactly dangerous.. unless you grab the two input ends of the transformer, one in each hand, nothing much will happen to you.

[James (pseudo-geek)]

wrong. most people don't understand mains lines. the - terminal is RUN INTO THE GROUND making the earth itself the contact. unless your floating, or encased in rubber, you will get shocked.

[James (pseudo-geek)]

err floating in the air that is lol, not water. water makes it 100 times worse.

[Adam Manick]

Not distilled water. It is still dangerous but there is very little conductivity in it

[leevonk]

unless you're floating in distilled water, then you're floating in both ways and you might as well be encased in rubber

[James (pseudo-geek)]

true. but who wants to sit in a tank of distilled water while they work on a transformer? much easier to just watch where you put your fingers.

 me....

I always thought that the 'earth ground' went into the ground (the circular third pin on wall outlets), not the reference ground (one of the flat pins) that's used in the circuit. Isn't the whole point of the earth ground going into the earth to make home electronics safer. Also, if you're using a transformer, doesn't that isolate the power and ground from the socket (except for earth ground). Imay be totally off.

[James (pseudo-geek)]

well that does too. AC (alternating current) means that it switches back and forth. it switches 60 times a second, meaning that 30 times a second the left pin is +, and the rest of that time, its -. same for the right pin only the opposite cycle. this means that if you touch a pin for more and .06 seconds, your gonna get shocked. pretty much unavoidable, so don't touch 'em.

[davidprosser]

That can't be right, cos i've touched a neutral cable before and not had a shock

[leevonk]

it's a digital clock, so it uses dc, and it's probably pretty low voltage dc (under 12 v), so unless he touches the tips of those leads coming directly from the wall he's fine.

[James (pseudo-geek)]

which was exactly what I was worried about.

[Derin]

Well,the generator neg leads are hooked up to ground themselves.

[Daddio_UK]

hahahahaha ... cough... sorry lol.

Someone gave me one of these that I like because it has huge LED numbers. They made it by hitting the snooze with enough force to bounce off a wall.

[zootboy]

Eh? That makes no sense. Please clarify.

[VIRON]

Someone smashed the case of their alarm clock and they gave me the guts inside which still work. It looks a lot like the picture.

[zootboy]

That's not what i meant. I was talking about your comment.

They made it by hitting the snooze with enough force to bounce off a wall.

Clarify that.
