I played Half-Life on it!

so basically we're smartly manipulating the flow of energy to solve complex mathematical problems? Oh, so that's what computers are!

Impressive. If you get bored again it might be interesting to think up a design for a memory bank and an instruction queue of some kind and make it into a programmable machine. :)

@NorthCountryTech It would be nice :). A significant problem is that balls only roll downhill... so setting up any system where things can feed back is difficult. Here, it's done with a large lever arm and a very long carefully adjusted string. That's tricky if you need to communicate a complex state back to the top.

What museum? There's something that looks exactly like this at the System Source computer museum in Hunt Valley, MD. Or did they just build one based on your design?

@ariw2003net Actually, that's the one :). They asked me to build them a copy, so I did (with a few additional things like routing for the overflow balls). Glad to hear it's still on display.

@brdavis5 Haha, that's a funny coincidence. I was just looking for mechanical logic gates/computers on the Internet and found this. I guess not too many people build this sort of thing. Awesome job, by the way, I have seen a live demonstration of this and it's really cool. Sometimes when I go to System Source, it's not really in a working state, but Bob usually fixes it sooner or later (he's my uncle).

@ariw2003net That is fantastic to hear! I'm glad you find it fun... and I find it FANTASTIC that it's still operational and (being made of LEGO) can be fixed and maintained fairly easily.
