hi,if you only supply a cpu ,it will consum small is is good mothed of using a LM317.but the LM7805 will be better,you can save two resistences.maybe this is the cheapest way to slove this problem.
what you need is to get ride of noise from motor.you can :

A lead acid battery needs to be charged with a constant VOLTAGE rather thasn a constant current. Having built many of these that moniter the voltage and cut in at various times I have come to the conclusion that the best method is to use a very heavy rectifier and a well chosen transformer the secondry giving a voltage of 14 voltes to maintain the

Ram: If i take a close look at the tds210 the display has a resolution of 320*200 or maby 400*300 so there should be no need for a 10 bit a/d converter. If the X-axis is 300 pixels and leave some room for streching the axis, 4 times more we need 1200 Bytes. (hope the acex got it) For every timebase the a/d coverter should use another sampling frequ

The basic circuits and construction for a charger/discharger/conditioner aren't that complex I don't think. Just need a nice way to bleed off a battery to discharge it without producing too much heat :)
The tougher part is the analysis of the battery, and the conditioning process. I don't know what that "conditioning" process should be.

Hi All,
A simple connection diagram is shown in the figure.
Can anybody suggest an idea to implement a zero crosing detector in software for this scheme. And also I need to sense the AC mains voltage level to switch from AC mains to BATT in case of undervoltage or overvoltage conditions. I prefer C language.
Thanks and Regards,

Hi Timoy,
The 330 ohm and the 1k do not have a direction. Resistors are not directional. The only other thing you need to make sure is in the right direction is the LED and the detector. If you want to test the LED just hook the 330 ohm to one leg of the led so they are in series. just like it would be in the schematic. Then place the volta

Its circuit is probably too complicated to make one so simply buy one.
You forgot to say how much power you need. 1mW? 1000W?
Buy two.
They are probably cheaply made in China and when the fisrt one fails in a couple of days then use the second one.
