Question

I want to do small electronics project. so please help me and give some idea.?

Answer 1

The best idea

Sit down ... relax on a chair ... think of all physics principles .. think of innovations/projects related to those principles

btw ... why for our idea you must get the marks?

Answer 2

u must choose an electronic to work on . and then try to find how does it work . and get on  work

Answer 3

Make an embedded system for secure communication using encryption and decryption method using 89C51 or 8051 microcontroller or any language.

Answer 4

An astable multivibrator circuit is simple, yet educational and also entertaining. The link http://en.wikipedia.org/wiki/Astable has a schematic of such a circuit. Besides the transistors, resistors and capaciators, include a pair of LED's (light emitting diodes) between resistors 1 and 4 and the positive rail (the horizontal line at the top of the schematic). The easiest way to construct this circuit is to use a "breadboard". It is a piece of plastic with several hundred holes running halfway through. Wires and the leads of electronic components are pushed down into the holes to construct test circuits. A 9 volt transistor battery can be used as a power source. Most of the hardware needed can be purchased from an electronics parts retailer like Radio Shack. Once correctly wired, the two LED's will take turns flashing on and off. The timing depends on the choice of capaciator. The larger the microfarad rating on the capaciator, the longer the period between flashing.

Answer 6

  Get a 555 IC and make a digital timer it's simple and impressive.

Answer 7

Make a door bell that plays different sounds...

U can also play around with tiny "spy" cameras and such...
