 | | Get 8 Outputs from RCX: A Pure-Lego Solution —Hao-yang Wang
|
| | | More precisely, here I am going to describe the way to make a 4-way power splitter. You can connect two splitters to the RCX to get 8 outputs in total. Within each of the two splitters, you can have one output among the four working at one time. (...) (26 years ago, 11-Mar-99, to lugnet.robotics)

| | | | | I'm not sure if the 4-way would work, but it it did you could put a 4 way on each of the outputs of the first 4-way, yielding a 16 way splitter. Of course this would require 10 polarity switches. Dave (...) (26 years ago, 11-Mar-99, to lugnet.robotics)

| | | | | | (...) This is a great idea, and it pushes the number of outputs up to 32: We connect two 16-way splitter to RCX, and use one direction of the controlling motor for both the "first-level" splitters and the other direction for all the eight (...)

| | | | | | (...) Now wait just one minite. If you connect up the outputs of a few of the 32-way spliiter to the inputs of other 32-way spliiters, you can drive many more outputs. How many outputs are we at now? -Kekoa (26 years ago, 11-Mar-99, to lugnet.robotics)

| | | | | | (...) But then we run out of outputs for the controlling motors. On the other hand, we may layer four stages of the 4-way splitter into a 256- way, then use both directions of the other two outputs to control these four stages... I think this is (...)

| | | | | | Does anybody know if the polarity switch has a neutral center position? In other words, does the switch go: forward<->off<-->reverse Please share with the group...

| | | | | I didn't look at the 2-way you mentioned but went into a 4-way specific which uses only electric cables, polarity switches, gears, axles and technic beams for a base. It worked! not only that but there is only a need for one 45 degree meeting of (...) (25 years ago, 3-Mar-00, to lugnet.robotics)

The side effect of the 2/4-way switches: one output is powered, other output from same switch is "braked", other two are free to move. I am looking at changing the design to "brake" all (...)
