Perhaps the drive manufacturers could design a drive so that the it wrote the same data to multiple platters (give up capacity for redundancy). If you are writing to a 1 terabyte platter stack and it writes 3 platters of the identical data with the same signal to 3 write heads on one arm, you could store 333gb of double redundant archive. The controller would compare the 3 bit reads and choose the bits that match. Of course the bearings and motors and pickups could be made redundant or at least of the highest MTBF. Not RAID... "RAIP" (Redundant Array of Individual Platters).

The system code named DESCH (named for Joseph Desch, who led the secret WWII project which developed a decoder for the Nazi Enigma encrypted messages.) collects terabytes of raw data gathered by the USAF Gotcha's synthetic aperture radar equipped UAV's orbiting over an area of interest in a war zone. The system images a 5km dia "city sized" view and processes the result into 3D image maps while recording to disk for review. The 400 Megapixel per second streaming images allow zooms into areas of interest, observation of minute changes and the ability to track personel and vehicals in the urban battle field. http://www.wpafb.af.mil/news/story.asp?id=123165818/

Insert old joke about Engineering student who took the bike over the naked girl

Actually, The designation of "Air Force 1" is only used when the commander in chief (See President) is onboard. Otherwise it is refered to by it's tail number. Any aircraft flown by a branch of the US military can carry the designation of "1" when transporting the president. Hence the designation on the presidential helicopter as "Marine 1"...

There's a difference between skimming a posting and reading it. If you actually read the post you would have understood that your described needs are not what I'm talking about. You want to build semiconductor manufacturing and I'm talking about earth movers. (I guess we need to come up with a new term for that.) You need to walk before you run and we don't have an infrastructure to crawl yet. I don't want Von Neumann's machine. I want to start by moving rocks around.

There's no reason to lift the mass from one gravity well to another. The real challenge is to design a robotic device that can make useful stuff from Moon dust and rocks. You have lots of raw material and an abundance of sunshine to produce power. If you focus a large enough parabolic mirror at the dust you can melt it or at least sinter it into potentially useful parts. Make them precise enough and you can build a large device out of the parts. It gives new meaning to Stone Age Technology, "Fred Flintstone's Moon Buggy and Bulldozer Emporium!"

After you make the shapes, you need is to add a power source to make it move and assemble it. If you are impatient, you ship the power source from the earth to the moon. We need to think small and make it work. Then build bigger and bigger stuff there. Of course the next step will be to mine the moon for metal and other resources to make your stuff with.

We also need to adjust our sense of time. The devices don't need to operate at a rate of motion that appeals to the "short attention span" people of today. Design a mechanism that accomplishes the task by moving from place to place on nothing more than thermal expansion of the parts. Shade your crawler device with a movable sheet of Mylar mirror film to block the sun and the parts will shrink. Let the sun hit it and it expands. design it for this and you could make a zigzag shaped device that snakes across the surface without any power source (as we would define it) Don't think it will work? Those tar strips in the road are there for a reason. It's called thermal expansion, and it moves mountains on earth.

Be that as it may... it's a greater likelyhood that the home enthusiast has no PCB layout program to create the board either. A used Laser printer with many home hobbiest years of life left on it costs no more than a cheep inkjet printer. Much like the folks who complain that they don't have access to a magical fabrication machine (ala Star Trek Mater replicator), they also would have no way of programming it to produce anything original. Since making a copy of an existing item would probably be a violation of someones patent or copyright.

By the way, you can take your inkjetted PCB layout up to any Kinko's and get a conductive copy made for pennies.

Uhh... It's called a Laser printer dude.

Toner is just carbon black with fusable binders in it. It's been possible to print and copy circuit boards for decades.

You gotta move beyond the inkjet technology and spread your wings and fly.

since we are just holographic projections from a 2D image into a 3D existence. There is no "Where" and there is no "When" to adjust to. As previously discussed, the universe may be a hologram theory would support the concept that all our perceptions of space and time and motion are based on our interpretation of the hologram as we sense it. Since we construct sensors to detect what we perceive to be true how would we know otherwise. There's no limit to what you can accomplish... if you don't demand credit.

Also at the show were examples of Samsungs prototype transparent OLED screens. It offers another way to "put yourself in the picture" http://www.oled-info.com/files/images/Samsung_Transparent_OLED_Ces_2009.jpg and http://www.oled-info.com/files/images/Samsung_Transparent_OLED_Ces_2009_2.jpg
