I realized this afternoon that I could cull a switch from my earlier design. It's now down to 12 switches from 13. 4 switches ganged onto each piston. The wiring schematic is here: (URL) on how to interpret the diagram can be found in an earlier (...) (21 years ago, 26-Jun-03, to lugnet.technic, lugnet.robotics)

(...) About half-way down this page (URL) is a diagram and short discussion of a possible design for molecular level RAM. The diagram shows 2 memory cells of 2 bits each and the mechanism to select which memory cell is being read/written. In my LEGO (...)

Inspired by the recent pneumatic computing thread I have created some LEGO mechanical memory. It is an adaptation of a possible design for molecular level RAM.

|

There is no way that, in the movie, Takanuva does not come to a screeching halt in front of the other Toa and throw a shower of dust on them. Is there a biker term for that maneuver? (21 years ago, 24-Jun-03, to lugnet.technic.bionicle, FTX)
