Ok i know this is an old console and i could probable save money by
buying a new stereo but! it means alot to me....Everything works fine
the 8 track,the am and the turn table But! the FM seems like it low on
volume? can you help me? it was my fathers stereo and had served him

Will this work to toggle power using a membrane switch?

To power up: The PWR button brings the SHDN button high, turning everything
on.  The processor keeps the SHDN pin high after after it boots up.

Hi, I'm re-designing a yet-to-be-implemented home remote control
lighting system that uses mechanical latching bistable (or impulse)
relays.  These particular relays will change state with a low voltage
pulse on only 1 input pin.

I bought a new monitor and all worked after I blew the inside of my computer
out with a dustbuster, as it was LOADED with dust. So perhaps the issues I
was having (only in the 1152 x 768 res) was monitor and dust related. I say
dust related as the monitor would not work the first ...

Thanks to everyone who gave me help a few weeks ago regarding the bass
amplifier that was doused in soda.  I ended up running the circuit
board under warm water in the sink, and rinsing it off with distilled
water afterwards.  It cleaned right up with no hard water deposits.

I need to share this with you!
It worked miracles
for me!!
Try it today!.

I have a quick question.
I have an RC low pass filter and I need to calculate the impedance so
I can match it to a SAR ADC.
What would the steps be to calcuate the impedance?

hello, I was wondering if anyone had ever encountered something like
my latest joy.
summary:
unit stops working, yet when you read in the program and e2prom space,

How close to 5V should a logic HI be? Is there any plus or minus
deviation from 5 volts allowed?

I am a musician and not an electronics genius but wanted to ask a
question and see if anyone could help me.  I am looking for the
materials and plans to make a VERY simple LED blinking device.  It
needs to be very small, (probably powered by a watch battery or

I have an application that requires 2 12V 7.5 AHr lead acid batteries to
be charged from 2 nominally 12V but actually nearer 18V with no load
1.5A solar panels, in the end i hope to get away with 1A solar panels
but first I need to accomodate 1.5A panels.

Does anyone know which standard practices are used in electronics
design for audio equipment?  Or electronics in general?  I'm trying to
learn more about IEEE standards, and I need a place to start.  Thank
you!

Heres a website that offers a free web page.
There are some good music templates.

What is now the easiest way to go for sine wave oscillators to work on fixed
frequencies near the middle of the audio spectrum?  Are there off-the-shelf
chips that will do the jobs?

During my school days about 35 years ago, we were taught in our
physics lessons, the radio wave only travels or reflect in our
atmosphere  when we listen to FM/AM ,CV band, Air band boardcast. But
I am curious to know how the radio wave communicate to the satellite
