I need to rent a 32-bit 33MHz PCI Analyzer /
Stimulator. I've tried many of the usual supects,
but no luck so far.
Any idea where I might rent one (or alternatively, buy

I have now got a picaxe chip to turn on and off a camera infrared remote and
so activate the shutter of the Canon G2 at regular intervals. (Thanks David,
thanks Phil)
Simple enough, if a little messy and tedious.

I have a Sony head unit (CDX-MP70) RMS 23x4 Peak 52x4.  I have it hooked up
to 4 Infinity Kappa 62.5i 6.5 speakers.  When I turn up the volume maybe a
little less than half way or more on the head unit the unit cuts out/shuts
off, then in about 5 seconds it pops back on and ...

I know there are many cameras which can capture IR~UV spectrum.
Then what about magnetic or electromagnectic spectrum?
Is there such camera device for electromagnectic field?

I have a need to control a light fixture in my home. At a certain time I
need the light to come on and later on the light should go out. The problem
is that I need it to change states slowly. Load could be anything between
100 and 600 watts.

In particular, what their accuracy is at low power levels,less than 50
watts.
The tech specs on the units seem very vague about this.

I've been trying to understand the theory behind the design of the
Ultra-LD 200W Power Amp Mk2 in the Aug 2008 issue of Silicon Chip. The
amp uses On Semiconductor's NJL3281D/NJL1302D ThermalTrak power
transistors. These have integral diodes.

If I drive an A/C voltage into two parallel wires taped to either side
of a magnolia leaf 4cm apart, how do I calculate/measure the electrical
field strength?
Can I just put JFET probes on either side of the leaf, 1cm apart, and

Greetings All
Can someone recommend a good software program that can do audio frequency
sweeps through the computer sound card, without me having to type in and
test each frequency separately.

Hello, I am very interested in powering 3 computer case fans by my
home wall plug.  I'm very electrically challenged, but have a few
buddies who have tools I can use.
Here is an example fan

Any thoughts or ideas?

Hi, guys.
I've had a quick search through the newsgroup archives, but not found
many recommendations for a quality charger for AAs and AAAs. I'm after a
charger which allows cell-matching and refreshing tired batteries, as

Lighting technology to replace incandescants, as an alternative to
inferior flurorescent technology (poor radiation spectrum).
Problem for now, too expensive.

Can you get microcontrollers that are programmed with Java. All the
onesi have found are programmed in basic assembly or C .
