Hello Mbmc! its roineust@post.tau.ac.il Thanks!

Hey guys! This sounds fantastic! Where can i find an adapter and a gear system, that can enable me to connect a DC or RC motor/servo, instead of a LEGO engine, which is much heavier, e.g. relatively for my application? I have many small, continuous servos, that weigh much less than a LEGO engine and i can control their speed easily, they have torque of 300-1000 gr/cm, would they be too weak? Is there such a thing, a servo to LEGO adapter? I guess i could build one myself anyway... Since i have null experience with LEGO and no parts at all, could you tell me what would be the best way to find the exact parts i need for such a pump structure plan, without needing to pay X20 times more, for a box of a model, that i am even not sure has the right parts are inside? Mbmc, that structure looks very compact and interesting, why, though, can't i see the pump itself in the picture? Is it just the picture angle? Do you have a detailed plan? How can i acquire only the parts needed to build this plan? Is it possible to connect a simple small DC motor or servo, instead of a LEGO motor? Do you know the exact weight of this structure? Mbmc, one more thing - does this structure output continuous and stabble pressure, which actually, if i understand correctly, requires, at least 2 pumps? One compressing, when the other retracting? So much obliged!

Hello! I am looking for the most compact and lightweight LEGO pump structure, that can output at least 12PSI - no need for reverse action (no vacuum needed, only pressure), could you refer me to such a structure? Do you have any idea, what would be the weight of such a structure? How many pumps would be needed with such a structure, to reach 12PSI? Thanks!
