I was thinking of using only one at the end (attached to the + where it goes onto the PCB), and running a lead to clip onto the first (attached to the - ). The 4 middle ones can be ignored.

|
|
I know that some of you use pneumatics for yuor robots. How do you do that? I suppose you use a compressor and a motor to change the valve, but that requires two motors and 2 is all that come with the MindStorms. Yes, I can buy more, but I´d like to (...)

I have been searching for the answer to this one for a while. My intent is to find a supplier who has small electrically operated (solenoid) valves which can be driven by the RCX output(s). I have found one so far, but the valves are very pricy. But (...) (26 years ago, 21-Oct-99, to lugnet.robotics)

(...) Only if the RCX was "on" at the time. If the RCX is "off" then power usage is reduced to a trickle, supplying power only to maintain the data in RAM, and in this state the RCX can survive for upwards of a minute or more, even with no batteries (...)
