Re: Some insects. Some flying. Some not flying.
Very nice! The last two stand out for me. Initially didn't notice the ant in the first one.

Thanks for your comments, Mark and Lou!
A dual function would be clever and economical. Maybe geared to different predators ...
Those spider mimic moths are spectacular!

Cuban roach pennies.jpg . Done with a Zeiss dissecting scope, focus changed by hand, images processed with a s...

Miscellaneous creatures

Seemed impossible to approach at first, but it didn't seem to mind when I laid down on the ground and slowly crawled toward it. Baby basilisk.jpg . An American Lady ( Vanessa virginiensis ) American lady.jpg . An od...

Re: FS: (reduced price once again) X-Y linear motion, X-Y tilt, and rotation positioning platform
How about $200? I've put it up on eBay (at a higher price, of course), but would rather sell it here.

Lovely image! Easyzoom does a nice job.
The symmetry of your composition is very appealing. How did you get all the appendages into such precise positions?

Re: FS: X-Y linear motion, X-Y tilt, and rotation positioning platform
Thanks for your comments, Chris. As I understand it, this device as a whole was referred to as a 'goniometer' by x-ray crystallographers. I have a very similar, but slightly larger one made by Philips that I'm keeping for myself. These were designed for very precise, fine positioning, so the excursi...

FS: SOLD X-Y linear motion, X-Y tilt, and rotation positioning platform
I believe this device was used for positioning samples in x-ray crystallography. The construction is very high-quality: the machining is excellent, I can't feel backlash in any of the adjustments, the movement is smooth in all directions, the engraving is precise. A lovely piece of work. It provides...
