Electronics Forum / Basics / November 2007

I'm looking the specs for a motor and one of the things it lists is
measuring voltage.  Based on the rest of the spec sheet this value is
not the rated/max voltage for this motor, so what does this term mean?

Can I detect power zero crossing on the low Voltage side of transformer by feeding the comparator on the pic with separately (half or full) rectified voltage?
Because I have the wave form in my head and I don't think I want to ( or even can ) ground circuit , I dint think 0V at ...

I have a 220 volt 13 amp table saw & a 220 volt 9 amp dust collector, the
latter of which vacuums up the saw dust from the former.  I would like the
vac to start when I power up the table saw, & shut down after the saw shuts
down.  Ideally, the vac would run 5 to 10 seconds after ...

Sorry if this may be more of an engineering question, but maybe
someone here has some experience of this.
I am making a toy for my son. There is a small motor which drives a

Some time ago I saw an advertisement, or thought that I did, for a neon
transformer, a high voltage transformer about half the size of a pencil.  Do
these things exist and where might they be found?  Google offers no help.

I need a "one-shot" circuit with enough power to close a small relay
for ~0.25s. The input trigger will go to ground and stay at ground for

duration is << 0.25s. Can anyone provide a reference, on-line or

Does any one out there knows how to build salinity meter, temperature
meter and pH meter? Do you have circuit digram there? i need your
help..please...

can anyone please tell  me what is the difference between scada and
dcs. Thaugh it is said that now these terms are interchangably used
but what is the difference in the implementation and goal of scada and
dcs.

I think this is a good ebook site. You can search for any ebook title.

I would be very grateful if someone with much more skill than me could
take a look at the datasheet for the TLV5618 serial DAC here and tell
me exactly what they would clock out of a microcontroller to set the
output of 'A' to 0, 2.5, and 5V?

I am working on a small project using a pic microcontroller that
I want to have run for months at a time. I can put the pic to sleep
to conserve power but I would also like to remove power to the
peripherals I am adding (i2c eeprom, etc). What I want to do is

Does anyone know of self contained 5V regulator for a 2 cell Li-Ion
battery that will also protect the battery from over discharge?
I only need about 50ma for my application.

Hello.  1st post on any group.  Hope this works.  I don't know squat
about electronics.  However, maybe someone here can help.  I replaced
my engine driven fan on my 2007 GMC with a set of electrics fans that
are wired through a 30 amp fuse for each of the two fans.  However,
