After some research, I proved to myself that small pneumatic pumps are best for
motorized compressors (what a suprise, Dr. Soh was right ;^)  For those who are

pneumatics, I learned much about pneumatics from his site.

Given that so many of my creations are pneumatic, I need a good compressor.
Here is my best so far.  Two battery boxes, two RC racer motors, and 12 small
pneumatic pumps arranged in two radial six piston compressors.

This made an appreance at BrickFest2004 but was not in working condition because
of broken hoses.

(...) Hi Kevin I've just been studying the pictures again and they gave rise to a few thoughts. The broken hoses, I'm assuming you mean they pop off rather than suffer fatigue cracking, so is this because the pressure generated inside can become so (...)
