hi fikic
u need to smooth down the tracks, cover the track edges of layout properly or else while
etching it will be a problem. -
hi
i have posted a circuit wch is a voltade divider in this wat must be the wattage of the resistor?? the load is the 4leds in parallel.
tell me the calculation too.

@gan87
you can try MAXIM and TEXAS INSTRUMENTS it is totally free...order samples in their websites. -
led's are 2v@10ma, i need to drive 50 leds, how do i connect in series or parallel ???
-
hi
how to drive led and supply constant current??
circuit for driving 50led's in series/parallel @30mA per led. ??? -
hi

i am really confused what to do, i need a stable fm transmitter circuit and it must be smaller in size.... someone pls help ???
-
how this circuit works can u explain audioguru ???
will this be efficient??
-
i have a problem with the current limit indicator it was glowing before but not now what should i check?
-
for getting TLE2141 go to texas instruments website and free sample it will be mailed in four days....

what will be range of transmission...will this be a better transmitter ???
-
what must be the input current for this amplifier??
2amps is ok?? -
hi
from this circuit can i get a negative power supply or some other circuit is needed?? -
sorry here is the circuit will this works fine...
-
i have added a circuit it is used for a 8ohms speaker what should i do for 4ohms load?

finally i have completed my circuit and it is working fine.... ;D :D
there was a small problem with pcb track and i have rectified it...
audioguru thanks for ur valuable help.....
ill post my photos as soon as possible....
how to measure the max load current ??? -
learn basic electronics too...
read these books....
electronics principles...malvino.
art of electronics...Paul Horowitz and Winfield Hill -
everything is perfect, the voltage across the base emitter and collector are constant ie 32.2V
can i also try with TIP3055 -
both the the resistance are available .33ohms 2watts....
how do i test the transistor 2n3055... pls help me
atmega8 volt/amp meter
