^he made a calculator with in game tools. Thats not easy.....

I have seen someone make a calculator out of Legos before. LBP is capable of some pretty neat stuff. I would like to see some cool puzzles being made though. Any links?

It is in most creation games like that.... so i'd guess it should be easy in LBP unless they screwed it up and made it too restrictive.

I could do this on a platform creator from the 90's.

The calculator made of legos is mechanical.  This is supposedly digital by using magnetic switches.  In otherwords, it's like he built a computer chip within LBP.  I doubt you can do that with legos.

That's impressive but I'm sure there has to be an easier way to do that. I know you can make a calculator in Source with significantly less trouble and I would be surprised if LBP was harder.

-edit-

And mind you I'm assuming this completely ignorant of how their trigger system works.  I'm just assuming Source because that just makes sense in my head.

Same concept.  It is just switching bits using multiplexers, binary logic, and such.  The logic is the same no matter what your using as bits.  If you take any computer architecture classes you will learn this stuff the first year.

i am finally impressed by LBP, if i had a ps3 this would be a first day purchase. I always thought the game looked good but that's first day purchase good right there.

It can compute tables of answers to 3 digits by turning a hand crank Full size photo   I have built a working 3 digit Babbage style Difference Engine, in effect a mechanical calculator/computer made from LEGO Technic parts. It has over 200 gears, 24 shock absorbers, and thousands of other pieces. Details including more photographs and theory of operation at: http://acarol.woz.org It can evaluate any polynomial of the form aX^2 + bX + c, for x = 1, 2, 3, etc. Calculations are up to three digits. For example, the normal "test" polynomial I use is X^2. The machine will output: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, etc. I am considering adding another digit column for four digit answers and adding another difference level so that it can evaluate cubic (X^3) equations. This would require doubling the number of rotor adders from four to eight. It stands about 18 inches tall and is about 25 inches wide. It takes a bit over 100 turns of the hand crank to compute an answer. That's about one answer every 40 seconds.

impressive but a little offtopic. The reason this was so awesome was because it was with the beta tools for a game.. it's basically the "level editor"

But yeah, pretty awesome :P got a video ?

Helpful bit of information:
