"If your comments are excessively inappropriate or you question why a comment was removed, YOU WILL BE BANNED. "
Ah, the sweet taste of power.
I especially like 'excessively inappropriate'. I always considered 'appropriatity' to be a binary state.
Weirdly, the phrase shows up on more than one comment enabled site, providing the answer to the riddle:
"What do 'concreteloop.com' , 'hollywoodteen.net' and 'thesuperficial.com' have in common?"
Also dailybubble.com,wesmirch.com, iwatchstuff.com, allegra.myblue.cc, isohunt.com, boyfuckgay.com, and benfolds.org
blog.peta.org.uk is a little more polite:
"If your comment is excessively inappropriate, or if you question why a comment was removed, you may be banned."
One of thesuperficial.com's commenters do say:
"hey, will somebody please post a comment that is excessively inappropriate and then ask why your comment was removed.. i want to see what happens"
Nothing seems to happen beyond casual yakkity about sodomizing Hasselhoff and sending him to space (two separate posts) : except the comment posting rules for that page do not contain the phrase in question. Retroactive edit?
Google claims 'about 2720' hits for "excessively inappropriate"
Yahoo claims ' 32,400'
Thats quite a spread.
Stepper motors seem tidy because they seem controllable. Pulse it once, see the shaft move x degrees. To move any distance, rinse and repeat. However, in a 3d printer, it seems that most of the time - all of the time is being spent on the R & R.
The problem - from a junkyard point of view - is that stepper motors are not as readily available as ordinary motors. And they need a much more complicated interface than a simple H-bridge or relay.
For a sophisticated mechanism, this is not a big problem. Steppers can be bought online with almost any combination of resolution and power. Stepper control circuit designs and boards are also widely available.
But the point of RepStrapping is to build a 3d printer out of ordianry and simple components.
So why not have a mechanism with a continuous motor that scans the entire print area, and just fire material at the right spots? Slaving the X and Y axes together would produce a slightly slanted scan pattern, but probably not enough to be significant. But slaving X Y and Z together would produce a nasty tilt. Unless of course, the frame was pre-tilted to accommodate the slant.
The biggest difference would be the need for accurate position measurements. With a stepper, you can be lazy and count steps from a starting position. The position's value will drift of course, but only by a small amount, and probably comparably along each scan line.
It seems to me that rather than screwing around with the usual poistion sensors, we should just take a look at the optical mouse. Mount a mouse in a poistion where it can scan a rail as the head moves. The mouse I use now cost $14.95 and claims a 2000 dots per inch sensativity.
being a USB device, to does not require any seperate interface to be used with the host PC, either.
This would also mean that the gcode would have to be compiled into a 'bitmap' format.

Found a picture of another tricot walnut. No real info with it though.

The Tuned Pipes of Silence
There is also no wikipedia page for Lucy Hosking. (!)
We're talking tuned pipes here, people!

EDIT: 30-01-2020....Still nothing, but now she is mentioned on the 'List of Keytars' page. (Photo of her playing a 'Royalex Probe') This is at 6,006,671 English Language Pages. I actually look forward to updating this again in 5 years.
Walnuts - Juglans regia - are dicotyledons. They have two seed-leaves, and the nut reflects this in its shape, being bilaterally symmetrical. So I was surprised when eating my way through a bag of walnuts to find one that was trilaterally symmetrical.
Does this mean that this mutation would be a tricotyledon? It wasn't just shell features: the interior nutmeat followed the three-lobed plan.
So how common is this mutation?
