I'm doing some research on materials forming and would like to
replicate the surface of a CPU die on the nm level. Does anyone have
any experience on removing the packaging on modern CPUs to reveal the
die?

They're on special at Rockby at the moment, $1.50ea

Subject says it all really, each power mosfet I find has a internal diode,
anyone suggest and 100V 10A devices without diode ? Nobosy seems to make um
like that :-\
cheers,

I'm not sure if this is the appropraiate group, but here goes:
I use a electric mower for my small yard. It is about six years old,
has a 12 amp motor and I use a 60' extension with a guage rating that is
one grade above the average orange outdoor  cable (can't rmember the

I need a custom home lighting controller for my disabled father.  What
I want it to do is control track lights that will be used like a
nightlight.  The operation is this:

You know, there seems to be more folks

Is there any way to make a dc power supply capable of 50+ amps at
12-13.8 vdc?  Basically, I'm looking for something to simulate the
power from a car without the whole battery and charger setup.  Parts
express sells a nice rackmount one, but I'd rather not part with $190.

I did a quick test circuit to soft start a supply rail using a P-chan
mosfet, bascially using a capacitor on the gate, so assuming capacitor is a
short when empty pulls the gate to the supply rail, and a charge resistor
charges the capacitor lowering the voltage on the gate by 12 ...

I would like to know the model and pricing
thanks

There is a new product on the market, similar to indeglow  in
technology, except that it's flexible and multiple sheets can be
combined and produced far more lumins.  Intended uses are  to cover
the ceiling or wall and have an entire surface as your light source.

I'm looking for a low-cost alternative to low-density conductive foam sheets.  I
need some 1" thick rigid foam for protecting the pins of LCDs.  The displays
aren't static sensitive, so I'm hoping to find something that provides the
mechanical protection without the expense of ...

I was wondering if anyone knew if and where i could get round lcd
screens manufactured or possibly the price range if i could get
someone to manufacture it for me. I've been doing some research and
all the manufacturers seem to only build rectangular ones, but yet

Hi Al, i have a pioneer vsx425 home audio amp in for repair with the
folowing problem.
When mains switched on the standby light comes up then faintly flashes.No
other functions.Traced it to the 5v stby circuit but cannot pinpoint

Went to dickies and jaycar but couldnt find anything I liked. I'll need
about 100 to start with so they need to be at the right price. Backlight
doesnt have to be blue but just something nice. Glass top would be
excellent. A good tactile feel - with good positive click action. Sorry ...
