Anyone have any info on capacitor equivalent series resistance meters? I
thought Capacitor Wizard used to be highly recommended. What are the
recommended units today? Wondering if there was something better for the
money now.

Sometimes I mess with older computers or controls that don't seem to work
for whatever reason, I'm thinking capacitors would be likely to go bad over
time as far as ESR going to high.

For simply identifying bad esr caps, build a cheap one:

If you want to know the exact ESR value, you'll probably want
a commercial unit.

Photo technique: Get slightly off-axis with the camera, and turn out
any room lights. I then process thru Paint Shop Pro to tweak the
brightness and contrast. (I just got Photo Shop, but don't know how
to use it yet Smile

That's not my photo. I just found that with Google.

Why would anyone use any of that 'stuff' if they already have the

Adobe Photoshop?

Gimp is so color-challenged that it can't even handle CMYK properly.

Because Photoshop does not remotely approach the capabilities of my
custom code, of course.

Also because photoshop is outrageously overpriced.

custom code, of course.

Most of the young engineers and scientists coming out of university
these days are Matlab-literate (numerate?), and Photoshop interfaces
beautifully with Matlab. Not only does it have incredible
capabilities, but they are relatively easy to use.

200 years ago you'd have been burned as a witch for having such
software.

Less than $700 from Amazon. Cheap for a business, but a bit pricey for
individuals. The whole Master Collection CS4 is only $2,300. That's
cheaper than most EDA packages or mechanical CAD packages (more of a
mass market) for an amazing array of functionality.

Enough tools to even work with the old Postcript files that I used to
write by hand 15 or 20 years ago (thanks in part to your writings,
BTW) and allow WYSIWYG and/or precise numerical editing. And it
understands Pantone spot colors so we can communicate with suppliers
anywhere in the world.

Indesign (included) is the best page layout program I've ever used.

Adobe ($3bn in sales) is one of the engines of the new economy.

The real question is whether it is overkill for your needs.
GIMP is far lower priced ($0) and has similar capabilities.

Not sure which version you are talking about, it works fine for me.
Version 2.2.17 and later. Then again i am not real demanding.

you can put a layer or two of toilet paper or tissue over the flash lens
to diffuse it's output.Makes for a better picture.

Why use a flash at all? Its not like this thing is moving, so a picture in
ambient light might look a lot better. The "magic eye" will probably look
better. I'll have to shoot a photo of my bridge and see how it comes out.

The pros use a flood directed into an umbrella-shaped reflector made
of something like cotton sheeting to give a "soft" diffuse source of
light.

many cameras will require the use of flash in indoor lighting conditions.

I have an old Sony Cybershot DSC-S70 and a (relatively) new Sony
DSC-T300. Both allow no flash, auto-flash and "red-eye", your choice.

"Shutter" speed and camera movement/blur are the main reasons.
