firstly you will need a solar cell 3V to power your electronic bell .after that you can make a 5Khz sine wave geneartor and connect it to solar cell and you should also use a timing and control circuit to cuttoff the bell after some time and when any one press the switch circuit energies and take the power from solar cell and alarm will start.
Outdoor solar lighting is available in a number of locations, including electronic stores, warehouse stores, and online retailers such as eBay, amazon, or Kijiji.

Whenever it likes you enough, holding the soothe bell will only make it like you faster.
Hello
you can not made solar cell in your home. This require diffusion process and other electronic processes which are performed by costly Electronic machines so it is not poassible to make a solar cell in home without using any electronic machine.
I have absolutely no idea
A solar cell is an electronic device that converts sunlight into electricity. An array of them is called a solar panel.
Well, if you're in the UK you can always get a cheap portable solar charger here for your mobile phones laptop and mp3 players here http://www.cheap-electronic-products.co.uk/detail.php?pid=21

You can make the liberty bell made.
Solar power as a concept has been around for centuries, but the first practical solar cell was invented in 1954 by Bell Labs. This marked the beginning of modern solar power technology.
Sometimes stores have home taco bell meals that you make at home, but taco bell tacos are only found at Taco Bell.
Solar panels were invented in 1954 by researchers at Bell Labs. They developed the first practical silicon solar cell capable of converting sunlight into electricity.
For us, one bell just after takeoff means that we are passing 10,000 ft. The flight attendants can now make their PA that it is OK to turn on your electronic devices. In the descent, one bell means we have just passed 10,000 ft. The FA's now make their PA to secure the cabin for arrival. You know seat backs and tray tables to their full up and lock position. Turn off all electronic devices etc. Two bells is a signal for the FA's to call the cockpit. Their is also a bell everytime the seat belt sign is turned off/on as an attention getter. Hope that clears up the mystery. Bunty maharana
The solar battery was invented by Bell Telephone researchers Calvin Fuller, Daryl Chapin, and Gerald Pearson in 1954. They developed the first practical silicon solar cell that efficiently converted sunlight into electricity.
There are many ways you could make a bell including shaping metal. You could also build a bell out of hard plastic.
