i had a search in internet for a floating led like what you see at the pic but with no success, i want to build a led vibrated clock like the pic so does anyone know any link for that kind of clocks?
thanks friends
really i have some of links about led propellers in my PC(that pic i have shown is not a propeller it is a floating led propeller:shock: ) but i wanted t build a FLOATING led clock no a propeller(see the pic),but i could not find any link about it
Doesn't the floating clock vibrate like crazy? Buzzzzzzzzzzz?
I saw one on a shelf at RadioShack and it was held from moving with tape.
Nothing stopped the shelf from moving. Nothing stopped RadioShack from moving. (They aren't in Canada anymore) :lol:
Meaby its an alarm clock so it starts at the alarm time.In the user manual its probobly stated that it works best if placed on a high shelf above the bed.
I wouldn't want to have a vibrating thing on a high shelf over my bed.
If you set it so that it begins to vibrate at alarm time then it's a different story. Ouch! :lol:
heyyy what do you are talk about?!
are you sure you never seen these kind of movement led clocks?
no perhaps the problem is from my broken english language!
my mean about vibration was a forward and backward movement caused by the coil for the leds, my mean was not a vibration motor like a mobile phone :roll:
The LEDs are on a rod that waves left and right. The LEDs and rod are heavy and their reciprocating motion causes vibration. I doubt that a cheap boat has a finely-balanced counterweight in it to cancel vibration.
Other kinds of LED clocks project the light of the LEDs on a wall or on the ceiling. They don't have moving parts.

Even if it was balanced it would still vidrate becose the rod is constactly changing direction.That will also make it vibrate(But not as much as it was unbalanced)
If it is perfectly balanced then it would probably make a twisting vibration.
They could add another object moving back and forth the in opposite directions to the swinging LED rod to cancel all vibration.
A mechanical nightmare to make an electronic clock.

That's why I suggested the propellor clock, it's almost identical, with only slight mechanical differences - you should be easily able to convert a propellor clock to a 'float' clock - the principle of operation is the same.
I've never been in a teeth-rattling 4-cylinder diesel powered car. My new car has counter-rotating balance shafts that reduce its 4-cylinder vibration so low that I don't know if it is running. I've read that the balance shafts spin at twice the RPM of the engine.
