I'd like to do some fiddling about with air valves/actuators etc (just for fun
things like opening small doors, maybe some simple logic gates - who knows maybe
a simple robot controlled from a PC! Anyone know where I can get some *cheap*
kit to try things. Tubing, air-actuators - and of course a small compressor/
reservoir. I see Machine Mart has some, but is expensive as are new. Basically
second had stuff if such is available. Any ideas? Thanks

fridge compressor plus gas bottle makes a fair air supply. The one
issue with fridge compressors is they spit oil mist, so this needs to
be collected and fed back in occasionally. Not difficult to arrange.
Feed rate is low, but pressure capability is high: ensure you dont
overstress the tank/pipes etc.

No idea on the rest, well I have but probably not that would be any use
to you.

Lego do pneumatic cylinders, for very small scale stuff.

Some are single acting, some double. They also do tiny thumb operated
pumps, change-over valves, piping, tee connectors, etc.

The prices are in US$ but many of the shops are actually in England and
will happily take UK£.
