how can i build a notification sound on my son's toy car, while it hittingsome where(with Jerking IC) Answered

hi, well, i would like to make a special kind of horn, for just making a notification while jerking the toy car of my son. now a days, he is hitting his toy car while driving his from Indore. so, i though that, if i am assembling a toy horn, with a jerking IC or a motion IC, it will be nice to him. but, i am not aware of, what and what needed for to make this. what i need to make is, if i am attaching this,under the toy car of my son, and while riding, if he hits some where, the body of the car will get a little shake, this point, the device should work as a notification horn. i am sure that, this will make more fun for him. be kind to guide waiting to get yours aithfully shinu

There's several ways to build something like this, but my standard way of doing things is to use a micro-controller such as a PIC or Atmel, etc., although a 555 timer can do the job.

For the horn, use can use a horn or buzzer from Radio Shack, or use a sound module to record any sounds you want, like ouch!!! You could use a 5v reed relay from Radio Shack to enable power to the sound device. http://www.electronics123.com/s.nl/it.A/id.499/.f?sc=14&category=2

The best thing for the vibration sensor would be a piezo element or a microphone. You could also use an electro-mechanical pendulum device such as used in a pedometer. Most of those kids shoes that light up when they walk use a pendulum device as opposed to a piezo. BTW, those shoes run on batteries!!!

There are some instructables for motion sensing devices.

A hi-tech overkill vibration detection device would be a MEMS device.

Here's an instructable I did which uses the sound module I mentioned, as well as a free sound editor to create any sound clip you want.
