Indeed, for those of you who don't know, that rocket is about 20ft tall, weighs around 500lbs, and has about .2GJ (yes, 200,000,000 joules) of ammonium perchlorate + rubber propellant. Sadly, it suffered an horrible structural failure a few seconds after liftoff (most likley due to a miscalcuation in the rockets stability), and came down in about 5 pieces. No one was hurt, Andy Woerner (the man behind it, although he had a ton of people helping him with it) got the publicity he was looking for, and considered the launch a success. Although he doesn't plan one making another one next year

This might not be a 'cool pic' for most of you, but for me its a godsend. This is a capture of a horribly adjusted 'scope probe, sent from my Proligix USB GPIB controller card, to my computer, to the KE5FX Data Acquisition Toolbox. I was so happy and thankful that I wrote everyone a thank you letter after my first capture. It's been a difficult road for me, but I can finally do it now, and I'm so happy!

I just realized I have access to a microscope here at work, so for a cheap, quick thrill, I photographed some 8-MSOP UCC gatedrivers.
1. You can see the mould flash appearing near the edges of the pins, 2. See how the top texture is ablated / flattened to give the text on the top of the chip, 3. This is the powerpad (just over 1mm^2) found on the bottom of the chip.

How did you get the camera and u-scope to work nicely together? I have tried a few times to get decent pics out of my scopes, but I always end up with a tiny spot on my camera, so the resolution goes to crap, but it looks purdy (see avatar, that is a late 1980s era IC on a clear (sapphire?) substrate, illuminated with a blue light, probably about .1mm across ). I even have one scope that is set up to project an image onto a bare CCD, but no decent cameras that don't have a lens permanently attached

Our microscope at work has a Nikon camera with a screw fitting attachment designed for the job. There is a control to divert one of the two eyepieces to the camera which sits vertically above the lens.

Here's some pictures I took tonight of a small crucible of molten sterling silver. The churning patterns that result as the surface oxidizes and then decomposes back to shiny metal have a mesmerizing appearance. I tried some different exposure times to get the color right.
