This is way, way more awesome.
Since I've got a long summer, I'm now really tempted to make a RepRap (http://reprap.org/) with lego like this. Imagine how cool it would be to show that to kids: A lego-robot making lego!
I'm thinking specifically of the "sticky fingers" problem, which says that if something binds strongly enough to an atom to "pick it up" then it's going to be very difficult to get it to "drop" it again. I imagine you'd have the same problem with Lego... although at least with Lego you can usually pick a block up by its sides, which you can't do with atoms.
Bacteria are proof that nano-assembly is possible, if you define assembly broadly enough.
Either way though, it was great.
Anyone a good idea where you can get cheap lego stuff? (maybe china @ bulk order?)
That's what heaven is like.
I too was looking forward to a printer that built objects out of lego. Would be a great project to work on.
Nevertheless, this is great. The printed sheet turned out much better than I had imagined. Shouldn't be too hard to put in different colour pens.
(Batman Lego is incredibly rare. Expect to pay a few hundred $ per set at least). Lego lost the license to sell it, but they still sell the Lego Batman video game.
From the supermarket, you can hardly get a 50-brick model for those 30€.
Now he needs to do a color version. Remember pen plotters? They had a carousel of different colored markers and it'd draw (raster or vector) with one color and then pickup a different color and output that color. Loved watching those things work.
I tried to do something similar in high school with some friends. We tried to make a lego robot that would draw like a hand does (not like a line printer). The difference in velocity between a drawing and raised marker created too much error for our robot, but we probably could have fixed this if we had spent more time tweaking variables.
Edit: The track is a remix of a Christopher & Raphael Just's Popper by Shinichi Osawa.
The track is on Shinichi Osawa's Teppan-Yaki: A Collection Of Remixes album. Unfortunately it isn't available in the Australian iTune's store. :(
He had to write the Mac OSX driver for it too. Awesome.
