Can anyone please suggest me some good project related to electronics….
….not something really hi-fi but something that i can understand at my level…..i’m doing b.tech in electronics(second year)…so i’m not a complete engineer….but i want to make something…..
…anything good would do!!!thanx in advance!!!..

Electronics Project!!!!?
Electronics Project Center – Part 1
All about an Electronics Design aid that I build over the past few months. If you’re into electronics and are thinking about building your own project center, then you might find this an interesting video. You can find the display I talk about at: www.allelectronics.com
LED Pulse Effect circuit
This is an LED pulse effect circuit. The effect result of this circuit is that the LED goes from off state, lights up gradually, then dims gradually.
This operation mode is obtained by a triangular wave generator formed by two op-amps contained in a very cheap 8 pin DIL case IC. Q1 ensures current buffering, in order to obtain a better load drive. R4 and C1 are the timing components: using the values shown in the parts list, the total period is about 4 seconds.
R1,R2 _________4K7 ohm R3 _________22K ohm R4 _________2M2 ohm (See Notes) R5 _________10K ohm R6 _________47R ohm (See Notes) C1 _________1µF/ 63V Polyester Capacitor D1 _________5mm. LED (See Notes) IC1 _________LM358 Low Power Dual Op-amp Q1 _________BC337 NPN Transistor
Simple Audio Mixer circuit
This is a simple audio mixer circuit diagram:
You can add some resistors in parallel connection for more audio input. To adjust the volume for each input channel, add linear trimmer or potentiometer with configuration: pin1> ground; pin2>output; pin 3>input.
Electronic buzzer circuit
This in a really simple electronic buzzer circuit based on timer IC NE555. The IC 555 act as astable multivibrator which will generate audio signal frequency. The frequency value is depended the value of 56K resistor and 10nF (0.01 uf) capacitor… you may replace the 56K resistor with a variable resistor to adjust the frequency.
