Close guys, keep it coming!
In fact it is the cathode from some some anodizing I had done, and I just left it in the sulphuric acid for a couple of weeks. So in the middle that's a 4mm aluminium sheet, and around that thick crystal growth of alum (aluminium sulphate). For some reason the crystals would grow outwards in sheets.

I must show off my new scope, a wee little Tek 222:
Steve got one a couple of weeks ago, so I knew I had to have one, too. Finally the bad scope days are over!
The second one is a completely random snapshot, we had the first signs of spring in Finland this weekend, so I had a lot of fun playing with my dog, rather than working on my project as any real nerd would have done.

What game are you playing? "Keep the snake away from the dog"?

After rebuilding my SSTC, I fed it a few blank CDs and it made some cool burn fractals. I used those black Memorex CDs for the effect, but after the burning was done it was very hard to view the fractal. I had to hold the disc up to a very bright light source and look through it.
So of course scanning it was a challenge; what I ended up doing was removing the lid from my scanner and holding a piece of paper over the scan bed at a 45 degree angle, with a 300W halogen worklight shining on the paper.
And the result:
It makes a nice wallpaper
And P.S. if the resolution (35MP!) and image size (764kB?) look mismatched, its because I scanned it on 1200dpi and then saved on Photoshop with jpeg quality set to 0! I thought it still came out looking pretty damn nice, tho...

Gotta love JPG, that would be roughly 3GB as an uncompressed bitmap

Doing a CQB training course we blew up a door, the picture is captured right as the explosives are ignited at the bottom, pretty amazing considering the burn rate it 6000 meters/second. its 3 times 2 meter explosive wire. Thats about 100 grams of explosives.
