#3d modeling
My 3D printer was making noise through the floorboards, which wasn’t loud but was still annoying. I’d seen people use tennis balls for reducing the transfer of vibrations between surfaces, so I came up with an idea of placing my 3D printer on a shelf and using lasercut pieces to hold tennis balls in place for the shelf to balance on.
Attempt one was a failure, as I’d measured the diameter of the tennis balls but forgot and used the measurement as the radius instead! Those are now being used as miniature tables…
The photos show the second and successful attempt. There’s no glue - the pieces hold together with a compression fit. And would you believe it - these actually work! There’s a lot less vibration coming through and thus the vibration noise is much quieter than it was before. There’s still a bit of noise from the motors and fans but it’s much better than it was before.
City of Boston Archaeology Program Goes Digital
“In order to make our collections accessible online, they needed to be in digital format. So what does it take to digitize an archaeological collection? We had to sort, rehouse, digitally catalog, and digitally photograph over 213,000 artifacts.”
Ancient handprints on cave walls in Spain found to include children’s hands
“They suggest their findings indicate that doing cave art was a group activity shared among all members, including children. They also suggest their findings hint that some other ancient forms of art, left behind as artifacts, may have been done by children.”
