hi frnzs
m designing a circuit analog part in which i have made a particular gain to boost the voltage level.i am using tl084 .when i change the ic .... i mean replace one tl084 with another one the gain changes. same thing happens with lm347,lm324...i have tried with atleast 25 brand new tl 084...
howtoincreaserom
i guess you can use extra EEPROM , as rkodaira also says the same, cause you see when microcontrollers(microprocessors) used to come without internal flash memory, external roms were used to store the program. I'm not much familiar with PIC but in case of 8051 i think it's possible
opamp gain stability
dear all
i have designed a analog amplifier using op07 . the input voltage is millivolts from..0-100mV and the gain of the circuit is 8.74 . when i apply the input the gain of the circuit increases slowly and takes upto 5 - 10 min to reach the full value. it doesnt shoot up...
hi friends
i am using a 16x 2 lcd having parallel interface .i want to make it serial interfaced. what to do? serial lcd are not available in my area. can i use some parallel to serail converter chips
bye
Thank you friends for replying.
about the reverse polarity of power supply---> actually i'm using circuitmaker to test circuits if you carefully look at the opamp the positive polarity is in downward position (acutally i rotated the opamp +mirrored).
i tried the circuit as shown in new...
rainfall detector
hi friends,
Is there anyway out by which a circuit can detect a rainful 30 minutes or a hour before it actually rains.
Please help me out.

Thanks for the suggestions. Actually i tried the same thing from a book by "jan axelson", below is the diagram of the same thing. But it didn't worked. actually i'm new to op-amps. please explain me in detail. one thing more one of my friend told me a op-amp wouldn't give...
adc0831
dear freinds
i want to design a voltmeter of range 0 to 0.1 volts using 8 bit adc (ADC0831) and atmel microcontroller 8051 with a full scale resolution .
00000000b should represent 0volts
11111111b should represent 0.1volts
please help me how to go about this
thanks
