First of all, no. I have nothing interesting in the world of compressors. I
got sidetracked building an all mechanical walker that has no gravity well. I
think it's a cool idea, which I may revisit later, but I think this design
requires more accurate tuning than is possible with LEGO. I'll try to get some
pictures posted.
Also, my RC Buggy motors are currently in a robot that needs to be drawn up in
ldraw before I can take it apart.
Anyway...
I have a couple basic questions.
Ignoring time, can both pumps (small & medium) reach the same max pressure? I
don't think the maximum pressure is really relevant, but the important thing is
trying to get the system to a specific pressure in the minimum time.
How does the "time-to-maximum pressure" relate to the "volume pumped"? I would
think they are directly related. In order to get a system to it's maximum
pressure, you must add a specific volume of air. Right?
So, to create a reasonable test, you could set-up a system using several air
tanks, a piston, and a couple rubber bands, like Ralph had for his switch (I
can't find the link)
Then, let all the air out of the system, and see how long it takes each one to
get enough pressure to expand the piston.
I'll have to try that
