My Canon Powershot A640 has an amazing macro mode, even with it's inbuilt lense. This pic is about 1cm from the lense, a scissor blade.

Nice blade shot.. Something I'll have to try, my casio also is 1CM with it's built-in lens.

Wish I had a fog machine!

The blade one is just .. more blade, so I decided to just use a little bit of it instead of posting a massive image.

As for the fog, I do have a higher resolution, however I can't seem to find it on my computer. The focal point is also quite small, so you only get a strip of fog particles in focus and the rest is blurred.

I was doing a science experiment on some coilgun designs (I might make a post on that later) and my High School didn't have the equipment I needed, which is unsuprising since they bearly know how to work an O'scope angry So I called up some local science institutes, I call up CSIRO greenmachine they had nothing, so I called up the ANU (Australien National University) switchboard and they hooked up me through to the Rescearch School of Earth Sciences, Electronics work shop. I told them about my experiment and they said sue! come around.So I went there for a week on work experience (to get around red tape, insurance) to do my experiment. The people of this facalty (only 7 of em) do repairs for the University's equipment (I saw alot of 30kV and higher PSUs about) and design custom equipment this includes worki on the SHIRMP (Sensitive High Resolution Ion Microprobe) mass-spectrometers! And they took me around to see them!

Some low energy shots (3.5-6J) using photo flash caps. I'll post more later.

Myke I'd love some details on this one (like, how I can do it myself!). Maybe start a thread for it. That first photo is absolutely fantastic.

Google chrome speed test is bull-crap:

I don't think that Youtube commercial is supposed to be a scientific speed test, just a collection of geek pr0n tongue

In any case, it's the speed of the browser they're advertising. If they were loading a real web site, it would be the speed of the internet they were testing.

I thought that video was supposed to be more a show of how fast chrome can render a javascript page, not the speed of the net connection
