Read above. You have already been given an answer that should meet your requirements. Surely you can get DC motors in Africa. If you control the motor by the output of a fire alarm through a relay you shouldn't have any problems. Should be pretty simple and cheap.I'd just do whats in the links I posted above. A plastic enclosure with a motor inside with enough amplitude to awaken someone. Really all you need is a DC motor with an offset load on the shaft. Changing the load weight and size can vary the "vibrations"
No way to vibrate unless you can provide it some power. At the very least you'll need an electromagnet of some sort that will take a decent amount of AC current and a large ferrrous plate of metal.guys. i am having problem since i cant get the readly made vibrator since i am from africa. so help me out how can i just develop is unising a permanent magnet and a spring
I've cheaked by my self(just now) and it 's working..I don't think a cellphone vibrator will have anywhere near enough energy to do what he wants. He needs something that will wake a sleeping person that is more than likely deaf. The person will need to feel the vibration through the bed or pillow.
i will make sure i post my project pictures once i am done.Hello lihle,
really nice project...
Use cellphone vibration motor nd make regid connection of it with the plastic case/box...
you can find such a motor in any cellphone,you just need to have screw driver(of cellphone) and some basic knowledge about operating voltage of vibration motor.
After completing project post your project pics...
Regards....
i've just tested the motor it is possible to use it. but first i will have to design the pad and then i will let you know about my progress.Samsung vibrating moter gives bettr result then nokia,so prefer samsung's moter...
in order to make project u not suppose to take moter from mobile..it can be availabe at native mobile parts shop...
Hi lihle,i've just tested the motor it is possible to use it. but first i will have to design the pad and then i will let you know about my progress.
lihle
i will have a look at it.Hi lihle,
Nice to see u again..
One thing i want to tell u that make hardware in such a way that maximum vibration can take place and moter must be perfectly fixed to it's place and same way comfortabe to put pillo on it and sleep..
Best of luck...
