Title: Babbage Difference Engine made with LEGO
Added: Jul 8, 2010
Author: aecarol
Duration: 1:19
Description:
This is a working hand cranked Babbage Difference Engine made using LEGO parts. It can evaluate any polynomial of the form aX^2 + bX + c for X:0 through N with answers to 3 digits.For this video the machine is set to calculate the squares of the integers. The video shows the computation from X=2 through 8. It will output 4, 9, 16, 25, 36, 49, and 64.See other mechanical devices I've built at: http://acarol.woz.org

Nov 10, 2011 - @BdBreese 1 - Please attempt explain to yourself why on earth you found it necessary to make sure I received your short and non educational opinion. If you feel you have to do so again, don't because you're wrong and repeat step one.

MucusFelidae Says:
Nov 10, 2011 - Yeah. Build a LEGO tripod.

Nov 22, 2011 - It's called a calc. Or smart phone cuz I dnt see the point it's Cool but no point

Nov 23, 2011 - dude thats sick! plz make a tutorial on how to build plllz!

Dec 10, 2011 - So is this why I should take calculus? Statistics is confusing enough.

Dec 29, 2011 - ouaa i love it i'm astounded a babbage machine how did you did it bro?

Dec 29, 2011 - The point is using one's brain. Might want to try it.

Jan 5, 2012 - I saw thig guys website and u need mad skills at math to build this thing.

Jan 23, 2012 - I never knew untill now, should I be ashamed?
Cityj0hn Says:
Jan 24, 2012 - No but you should know you made a mistake. By not reading the original comment I responded to you have wrongly concluded my correspondence to be about knowledge. You should not feel ashamed about it unless you fail to learn from it.The other person should feel ashamed for saying this video is a FAIL because he doesn't understand what it is that is shown in the video while Babbage also created the very thing he is using to burn someone else who does.

May 5, 2012 - what a smartass you are.. i hardly doubt that more than 1% of all people who use computers know who babbage was and what he did.. so that statement is absolutely inappropriate.
Cityj0hn Says:
May 6, 2012 - I am allowed to be a "smart ass" since I am in the top 0,1 percentile of humanity. Now try to put your feeble mind to work and imagine how much I could care about probabilistic statistics made up by an average person with no skills.Next time read all comments moron (moron; with an IQ of 51-70)

May 7, 2012 - What is it doing?
ILoveMixery Says:
May 8, 2012 - i doubt that the top 0,1 percentile of humanity argue on youtube and insult people for no reason. you are a joke. a rather pathetic one.
Cityj0hn Says:
May 9, 2012 - Arguments require argumentation and since mostly only fools like yourself disagree with me I and start their sentence with an insult I am never required by any ethical standard to argue at all.Your doubts are again founded on no knowledge of the subject yet you defend the doubts you have like they are part of your persona.Please feel inclined to once more shine a light on more of your doubts and hopefully you will listen to the facts I give you.
ILoveMixery Says:
May 14, 2012 - what facts have you given me? pretty much all you have done was claiming that you are the reincarnation of einstein. i dont see any reason at all to take you serious. the first thing you wrote to me was "I am in the top 0,1 percentile of humanity". that alone proves how hard you are trying to profile yourself on the internet and that you are looking down on other people just because the probability of them having an higher IQ than you is low. therefore i see you as a fucking joke. goodbye!
Cityj0hn Says:
May 15, 2012 - Einstein lived a full century ago, he does not compare well with me.My claim as you are so unfit to comprehend it was that it is foolish to state this video is an absolute fail and that it is not impossible to decode the function is of this Lego gearbox.Furthermore I stated in response to you that no sane person could ever disagree with this belief and therefor you must be a moron, meaning a person with a very low IQ.There seems to be no limit to the stupidity you so eagerly show off.

May 18, 2012 - Why are peeps flaming this video & each other? Given a work of genius like the Difference Engine, shouldn't you be applauding?
Jorbs3210 Says:
May 27, 2012 - Could you PLEASE post building instructions for this or maybe an .ldd file? I'm sure a lot of people would really appreciate it. Thanks!

May 28, 2012 - This is amazing !!!!
Steve98052 Says:
Nov 8, 2011 - There are easier ways to evaluate quadratic polynomials, but I doubt there are any _cooler_ ways to evaluate them.However, I would have thought that someone capable of constructing a difference engine from Legos would have been able to build a tripod for his or her video camera.
