More and more experimentsare now ‘PC-assisted.’ Alsoconventional acquisition systemsare very expensive. Since portablePCs are today common and a USB linkis a better solution than an old ISA bus,here we present an oscilloscope usingUSB port of the PC that operates at upto 10 kHz with ±16V input voltage. Ithas much more improved features thanthe PC-based oscilloscope and LEDscope for audio servicing published inEFY Dec. 2002 and Electronics ProjectsVol. 8, respectively. The oscilloscopeuses IC PIC18F2550 from Microchipas the main controller ....etc

Abstract:
This is one of great project based on AVR microcontroller. It use ATmega32 as processor and LCD 128×64 pixels for display. If you need to measure low frequency i thought this project, AVR oscilloscope, will be usefull. Maksimum frequency for AVR oscilloscope is 5 kHz (square signal), other signals (sine or triangle) the frequency is lower ( almost 1 kHz) for having clear view of the signal. Voltage input range is 24V AC / 30V DC.
This project use C language and CODEVISION as compiler. So, it will be more easy to understand t ....etc

5-BAND GRAPHIC EQUALISER


This equaliser uses low-cost op-amps. Good-quality opamps powered by a single voltage supply are readily available in the market. The op-amp should have a noise density of less than 24nV/√Hz, slew rate of more than 5V/μs and gainbandwidth product greater than 3 MHz. The NE5532 or LM833 used in this circuit meets these requirements. Equaliser circuits typically divide the audio spectrum into separate frequency band ....etc

please help me to make an oscilloscope using avr with sample rate of more than 1000s/s . but i dont need very high rate. maybe 20ks/s is enough for me and the price is much more important.please help me

hello
My name is bode..
i am a Msc student and i would want towrite my project on alternative authentiation for social networking websites. here i propose to use pictures as a means of authenticating users on a network where users would have to choose two pictures or more while enrolling on the network, and as a means of authenticating a user when he wants to sign on to the system the system would present the user with pictures that contain the original password and some other pictures as well. these other pictures would serve as distractors. ....etc
