LEGO Logic Gates Before you read on, if you have had trouble accessing this page then please accept my apologies. The previous bandwidth issues should be solved now that I have a new server. Also if you have emailed me an not received a reply, then please try again. I think my email forwarding has been intermittent in the last few days so I may not have recieved your email. Ok enough of that, please read on and enjoy. A few people have designed boolean logic devices using LEGO pneumatics and gone on to develop fundamental computer devices such as full-adders and flip-flops. These have been discussed greatly on LUGNET. I had suspected that there would be a large number of logic devices using mechanic principals, but a search for mechanical logic devices didn't get many hits. I got one hit on mechanical logic detailing the use of rods to make logic gates. To my suprise I only came across two LEGO webpages that gave any details of mechanical logics gates. The first page, has details of a LEGO NOT gate. And the other page has photos of an AND gate. If you made any mechanical logic gates then please let me know!

Bez ThomasI originally considered using a clockwise rotation of an axle for logical 1 and anti-clockwise rotation for logical 0. This is the method used in the other LEGO logic gates I found. However, I simply couldn't conceive of any simple way to decouple the axl
