Hello, I have a power transformer that converts 110 v ac to 12 .6 v
ac. What is easiest way to change 12.6 v ac to 12.6 v dc to run a 12 v
fish pond pump continuously. Thx..........Vic

Anyone see any issues with paralleling two or more bridge rectifiers to
increase the total current capacity and reduce each components individual
heat signature?
Thanks,

I was just wondering if you can broadcast an audio signal  (100 Hz to
20 kHz) over the airwaves without upconverting it.
Are there any problems with doing this?

   i am confused with saturating n bit counter. Is it not simply a
normal counter with following sequence ??

I have a electronics newbie question. I have a HP E3631A power supply
that has an "Output OFF" option that 'turns off' the outputs. Now, I
would like to know what is the difference between using this option,
and setting "0.0V" output on the power supply. Does setting 0.0V mean

Hey everybody, Anyone care to help A newbie figure out what part
numbers are all about? what I mean here is... I have many parts
( transformers and such) with only a number stamped on them. Is there
Any kind of code or reasoning that corresponds with these numbers?

I was recommended to use a analog multiplexor to expand the number of
ADC ports on a picaxe "cpu" earlier.
I have now tried to use them for a few days and cant get it working, any
help please :)

i am having problems building a device to interupt a high voltage
flow
of electricity.
i initialy tried to use an optocoupler, which i hoped would respond

games, toys, GPS etc. It has tips under every deal on how to save on

is there anybody here who is familiar with "calculus for electronics"
by a.e. richmond and can recommend other references on circuit theory
along similar lines? thanks for any help you can provide.

I have two RCA transistors; one has a black cap with three short leads
forming a straight line, the middle one closer to one of the outer
leads. The other one has a silver cap with three long legs forming a
triangle, with a tab on the cap. Does any swell person know the leads

greetings gurus
i've been trying for some time now (though admittedly off-and-on) to
self-learn basic electronics, and it's painfully clear by now that i
have rocks in my head in this respect. what i AM quite good at,

Hi I'm building an instrument with several circuits in it.
I want to run them all off one power supply rather than several
different battery packs, I want to run 4 3v dc circuits from a 12v dc
power supply, can anyone point me to a schematic i can adapt?
