A Lego testing machine for Lego compressors... wow, one of the coolest Lego things ever seen around! I love the idea and love your implementation, and find your results very useful. BTW, I think that the Ralph Hempel's double-action compressor performs sub-optimally due to the fact that it doesn't use the full stroke of the pumps. Michael Powell's compressor drives the pump with a medium pulley instead of the 24t gear. The distance between two opposed holes in the pulley matches exactly the stroke of the pump, while in the 24t gear the holes are slightly closer. Mario http://www.geocities.com/~marioferrari

(...) I have tried to emphasise all the time in my web pages. It has probably reached the theoretical limit of efficiency for the small pump. It will be difficult to build another compressor that can surpass his mini compressor. On the other hand, (...) (25 years ago, 28-Sep-99, to lugnet.robotics, lugnet.build, lugnet.robotics.rcx)

		RCX Controlled Air Compressor Tester
Hi, all pneumatics fans, For some time I've been trying to figure out how to objectively compare the performance of the various air compressor designs especially the ones using the large pneumatic hand pump which seem to be coming into fashion (...)
