I think this diagram should explain the differences: (URL) is the N-input differential output AND gate, developed from your sketch. I've used 2 switches for A, to gate the supply so that it doesn't leak. This gives 2+4++4 switches for an N-input (...) (19 years ago, 25-Aug-05, to lugnet.technic)

(...) I mechanically link the two pistons together so they act as though they were one larger piston, also I mechanically link the four switches. This eliminates any issue with racing between the two pistons and their switches. Could you explain in (...) (19 years ago, 24-Aug-05, to lugnet.technic)

(...) Thanks for the kind words Vineet! What I meant was; before the boom only elevated to about 35 degrees. The real ones go past 45 degrees. It was a good design that needed improvement. I think it is lighter now too. One good tip I got at (...) (19 years ago, 24-Aug-05, to lugnet.technic)

(...) I'm looking into alternative gate designs and I'd like to have a good library of them on my Brickshelf to then use as a resource for article pictures. This includes N-input gates of each type, as I intend to draw the module that can be (...) (19 years ago, 24-Aug-05, to lugnet.technic)

(...) I don't know about stronger, but they're definitley smoother. There's less play between the newer gears. They're also wider, so there's more contact between the tooth and the gear perimeter. That may make them stronger. The only drawback is (...) (19 years ago, 24-Aug-05, to lugnet.technic)

Does anyone know if the newer double bevel gears are stronger than the older lego technic gears? By stronger I mean won't break under pressure like the older ones. (19 years ago, 24-Aug-05, to lugnet.technic)

I spoke with others at Brickfest and they said they would buy the book and I would probably (...) (19 years ago, 24-Aug-05, to lugnet.technic, lugnet.events.brickfest)
