Oops, well it looks like it might have been reviewed by NASA.
This means only one thing, we need to start training Bruce Willis for space flight so he plant a nuke on Apophis and save us from impending doom!
The point of RepRap, is to make a machine capable of printing most of its parts, and having the rest of the parts be so cheap that anyone could purchase them.
It can't produce its own ink, but PLA can be made by fermenting certain plants. http://reprap.org/bin/view/Main/PLA
Ideally, you'd have an ink based on cellulose so you could take lawn clippings and make them into a car.
Well, some people have even been evaluating making printer parts from BEER, gelatin, and sand.
Currently, it doesn't.
But, there are several ways to produce circuit boards: The most promising is milling copper clad with a router attachment instead of a 3d printhead(called an extruder). Other ideas include printing a sheet of plastic with trenches in it and filling up the trenches with low melting point alloy to connect the components. There's also conductive ink, but that's a wee bit expensive.(made from silver)
Reprap can't do metal parts yet, but there are several ideas on doing this, either print out the metal directly with a special metal printhead, or print a wax part, and do lost wax casting.
As for semiconductors, it might be a while before someone does that.
If you're worried about RepRap taking over the world, you still have some time, the prototype printer has only printed 99% of its printable parts.

Still, no one has scrutinized the boy's work for math errors. So don't start training Bruce Willis just yet.
In other news, the sales of fallout shelters has dramatically increased within the past few days.
Not peer reviewed.
*Cue Mute City Theme from F-Zero.
Now that's bleeping 'creepy'.
Then use steganography if encryption is banned.
2 words: use encryption.
I've had it with this domestic spying, I'm going to get me a high powered laser mount it on my telescope and aim it at any passing spy satellites!
Ahem, has it been peer reviewed?
Dude, I think you fail to recognize what understanding mass means. Mass is just so fundamental. Just about everything has it.
Sweet! These breakthroughs bring us ever closer to a portal gun.
I would like to note that this was an online survey done in an informal setting. It has just about as much worth as any slashdot survey.
Another good physics simulation game is RigidChips, it taught me vector math, physics, and programming. It's very simple to use and also quite fun. It also allows you to create simple games. The only problem is that all the documentation is in Japanese. http://en.wikipedia.org/wiki/RigidChips http://www.iamas.ac.jp/~takeya04/softwareE.html
I guess this means the saying that "everything is bigger in Texas"* must be true. *except for microchips, which in Texas are in fact smaller.
But, what if they start building 3d printers made out of Lego to make more Lego? Like this one: http://www.instructables.com/id/Build-a-Polar-3-D-Printer-from-Legos/ Unfortunately, it seems to have a driver problem.

If anything is going to cause a grey goo scenario, it's not going to be reprap, it will be this: http://www.youtube.com/watch?v=7hEXwyJ2B78

Lesson #12: if they get addicted, they'll pay more.
Ah, yes, I forgot, you need MASS to react against. Which makes sense for a cargo ship.
Why no gyro? Gyros don't need any fuel for attitude control, just solar power. What advantage does not having gyros give you?
