The Evil Mad Scientists were presented with a challenge: inscribe one of Cliff Stoll's hand-blown Klein bottles, an object of surpassing beauty and odd topology. They modified an Eggbot plotter to etch the surface of a Klein bottle with a diamond engraver attachment.
So how would you etch the curved surface of a Klein bottle? It turns out, to our surprise, that it is remarkably easy to do it with an Ostrich Eggbot fitted with a diamond engraver attachment.
There was one complication, which is that a Klein bottle is a funny shaped object! In order to fixture the Klein bottle in the Eggbot, we made a couple of extra large couplers—much larger than the tiny pads normally used to hold the ends of an egg—with EVA foam rubber pads on their surfaces. The extra large couplers held the Klein bottle securely for rotation.

Even after months of working from home, you’d be forgiven for thinking the whole experience still doesn’t quite feel…well, normal. In addition to all the obvious environmental changes of handling your 9 to 5 from your den or dining room table, the technological aids you didn’t realize you loved back at the office probably don’t […]
Running a small business drops a lot on to the plate of just one person. And between juggling a dozen tasks that need to get handled daily, it’s no surprise that there are a dozen more equally vital tasks that can just as easily go overlooked. While posting to social channels and making web posts […]
The importance of reading is well documented. About half of America’s unemployed between 16 and 21 years old are functionally illiterate. And there’s an almost direct line between how much you read and your earning potential, with the richest Americans three times more likely to read than those with a household income below $30,000.
