(...) Haha! I've found a better way to do it, and a better drawing :-) Take my Pick and Place robot circuit: (URL) out the Elbow pistons and switch and connect the Elbow piston inputs to the Wrist piston instead (effectively draw the horozontal (...) (19 years ago, 20-Oct-05, to lugnet.technic)

(...) Hi Mark, You are right. I've had the wrong term in my head all this time. Gray code is not what I was thinking about I guess...... I'll have to go study Gray code better, and then study your descriptions. Man I wish you had a scanner and could (...) (19 years ago, 20-Oct-05, to lugnet.technic)

(...) Hi Kev, I think the cheapest way to do 3 or 4-bit binary with pneumatics would be to use gray code and convert it. Gray code always changes the least significant bit possible in order to achieve a change to a new state, so there will always be (...) (19 years ago, 20-Oct-05, to lugnet.technic)

When I was approx. 16 years, I built (URL) this> (book 8889, pages 38-41). Lousy picture, I know (my dad didn't want me to take a picture myself). Trying to rebuild something without building instructions was always more challenging... ;-) If I (...) (19 years ago, 20-Oct-05, to lugnet.technic, FTX)

To all those pneumatic gurus..... The classic pneumatic timing circuit made with one switch per piston changes state following gray code (i.e. only one piston changes at a time). This means that a two piston timer goes through these states: (...) (19 years ago, 20-Oct-05, to lugnet.technic)

(...) I really wanted to use the 4.5V motor from [LEGOSet 8700] since the motor is near-identical to 870's, but the battery box from that set is cylindrical and very long, so it's doubtful I could make it fit in there. However, if I decide to use 9V (...) (19 years ago, 20-Oct-05, to lugnet.technic, FTX)

From memory the crane was a bit of a clunker with 4.5v. Let us know how it goes with 9volts in the back ! Steve (19 years ago, 20-Oct-05, to lugnet.technic)

Here's a reliable scheme for controlling unmodified switch points with pneumatics. This scheme is for use on track that is raised up off the baseplate in modules.
