I think we need a better picture. Try a darker background and light from

You need to learn more about Usenet.

First, you need to learn how NOT to start a new thread with each post.

Hi Baron

I think this is all wrapped up now. But warm thanks for replying.

jerry mumbled incoherently to the rest of alt.electronics:

Really the amount you shave off by correcting course deviations will be
negligible in comparison with the drag/weight etc. IMO you'd do better if
you just concentrate on not going offline in the first place? I swim fairly
regularly and every 3rd stroke doesnt allow that much deviation from track.

I think you'd be better suited to training yourself in how to not lift your
head so often until you're approaching the bouy - thats just a matter of
practice and awareness of your own speed and the bouy distance.

I like this idea actually. Spam the spammers I say. Since they've been
using fake email addresses we can't get back at them that way, but it's not
so easy to change a phone number...

Is your fax machine being loaded up with useless offers and unwanted

Hello,

Ideas please?

A small professional UV box with two 8W tubes will cost about �100, and is,
professionally made and neat and tidy. I'm wondering if for sake of ease it
would be easier to just go out and buy one?

I've seen the UV "fly killer," tubes on eBay for say �10, which are
mentioned in a few of the tutorials online. Ballasts I have at home
somewhere. Would need a neat little case, cut glass, switches, bits bobs,
and time.

This is all purely for making the odd PCB so nothing commercial. There's
also those little UV nail boxes for curing the plastic, they're only about
�20 although I wonder about even coverage with those, and if indeed it is
the right type of UV?

Circular tubes? U-shaped tubes? Straight tubes? Little 9W dual parallel
tubes?

I'm just wondering in the end if it would be easier to just buy one,
although that's not really in keeping with the spirit of diy.

Many thanks for any input, I'm just looking for ideas and opinons really.
I'd also be half tempted to put in regular tubes too so that it can be used
as a light box.

Friendly regards,

Alison

ps. There's this one at Rapid for �110 in a little kit;

http://www.rapidonline.com/searchresults.aspx?style=0&kw=34-0690


Greetings,

Just an alternative, but you said inputs are welcome

You could print the pcb-layout on a laser printer using this "glossy
photo paper" eg "EPSON Photo Quality Glossy Paper type: SO41126".

Next you take a normal _CLEAN_ pcb - not the photo sensitive type - put
the paper on it and then simply ironing it on will transfer the layout
to the pcb.

Etchy - Etchy - Etchy and you have your pcb. As long as you keep the
tracks / spacings > 25 mils you should be ok.

It is cheaper than buying the above mentioned kit but produces it bit
more coarse pcbs.

One more alternative is www.olimex.com. They produce a Euro-card for you
for $ 56 including P&P.

We, the people, gave the uni's 7 Billion this year, seems more than a
'very little'. They also garnered an additional 6 Billion by the means
you mention.

Not sure where you get your figures from, or if you see how they are split
down and attributed to what - as i say, most funding doesnt go to the
undergrad students.

Oops. I always post off-the-cuff so I've had to look on google.
Was way out of date with my figure. Looks like it's over Ł10 Billion.

(also somewhat surprised to learn that medical training takes a whopping Ł2
Billion of that and docs cost Ł1/4million each )

Actually you're fairly on the nail with your original figure from what I've
just been told, 7.5Bn is more accurate, 10Bn hasnt been acheived - as usual
the government finds ways of claiming its doing things but doesnt. I'll
give you that though - i was mis-informed.

We've all heard that a million monkeys banging on a million typewriters will eventually reproduce the works of Shakespeare.
Now, thanks to the Internet, we know this is not true.

The biggest difference between sex for money and sex for love is that sex for money usually costs a LOT less.
