Will actually connect LEGO pneumatics with regular aquarium hoses?


Yes! These are the adapters for the miniature airline I was talking about. I
used them in my window walker to connect the pneumatic tubing to the suction
cups:

Sweet!  So with these adapters, I can use regular aquarium hoses, which
can be bought for pennies a foot -- way cheaper than LEGO tubing.

Elbow, tee, and cross connectors for aquarium hoses are also really
cheap, and I've seen aquarium hose check valve that go for less than $2
a piece.  I'm betting that some really neat stuff can be made with those.

The only thing I think I'd be left wishing for here would be some sort
of electrically controllable form of pneumatic switch -- but not just a
simple solenoid valve, rather a mechanism whereby multiple such valves
could actually be individually controlled by a single motor output from
an RCX (although it would probably require two motor outputs... one for
power and another for addressing).

Any EE's here up to that challenge?  :)
