Hi. I've been trying to buy a new audio setup but I'm confused about
quality. Years ago NAD & ONKYO, Bose Etc were the benchmarks & watt ratings
gave some indication to us uninitiated as to what we were getting. However,
I'm now reading reports on Logitec's equipment being better ...

I have a video transmitter and camera that is just the right size for
putting on a mobile robot.  The problem is that it takes power from a
typical wall wart power supply.  I want to "cut the cord" and go mobile, and
to do that I need battery based power that will output power in ...

Where can I order ADXL*  accelerometer (ADXL 202 in particular) in
Australia?

Hey guys, i have another question for a project in one of my classes.
We have to design and build a power amplifier as part o fthe final
project. Now the rquirements are really basic, in fact, so basic, i
want to do more, which is encouraged.

Hey all--
I know more about software than hardware, but I'm designing a
demonstration application for the JStamp, an embedded java processor.
The application is a quad servo controller. (I'm referring to the hobby

    A friends' Sony KV-F29SZ2 has an unusual fault for a
TV with a Trinitron type tube.
The convergence is terrible for the top 1/4 of the screen,

Morning all,
My monitor has the following fault
Hight varies considerably from say.

I am looking to buy an inkjet printer, DVD recorder with hard disk, and
home theater system.  The problem is that I am living in Italy
(220V/50Hz) and may move to the U.S. (110V/60Hz) in the future.  I
