I want to make camera flash with 220 volt ac power instead of ocsillator and I need a circuit if any body help me.
and I want to control flash lamp with transistor so is it necessary to open the connect of ac power from flash capacitor. and so good if you know the current of flash...
can you say me what is the reason of generating pulse(25 khz connected to coil)
in flash circuit (you ave send me) and what is the specificetions of first coil from
left in the picture.
XP home edition vs .Net
1.Can I install the .Net platform on Windows XP home Edition .?
If no what is differences between the xp professional edition and windows xp home edition.
2.Can I install a new platform on the laptop with the default platform .?
thank you it was so good with last method I get response I wonder that when I open the c between T1 collector and T2 base and input signal to it it works so good and it has equal amplitude for all frequencies and although the feedback network does not change the amplitude or...
I have test the power supply I think it is beacuse of some other l or c in my ciruit
this is my circuit has been attach and 2 transistor of the first used for oscillation.this is the circuit of lc meter.
by the way of calculate c and l and r of the line in this way we calculate aproximation of main Zc but when my cable lenght is about 1 meter and freq=900Mhz we have disturbuted c,l in all of line and we have some difference between calculations.I accept your opinion but I dont know...
I have a ocillator with 2 transistor but it has 2 distortion:once it is one other frquency on the sine wave (it is not harminic) I think my circuit has another resonance frequency but it is dammped like I mean we have a dammped sin wave in each period of main sine wave.another...
I am designing PLC(power line carrier) and I am using IC MC1496 for my project.The output signal of this IC is connected to LC load that this LC is coupler of signal to distribution line .How I must match my IC with this load?
The unload signal is sine wave and the loaded...
