[QUOTE="GemaRastem, post: 2077046, member: 560007"] I'm using pneumatics and work in a fluid power testing facility...We have all that stuff laying around. We'll be needing to dig out an air tank out of the basement, already have a valve that can cycle at 65hz or lower, the cylinder is going to be .25" bore, probably weigh about 5 pounds. =$0 [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG] I'm going pneumatic, easier than hydraulic. I dunno about the cone slamming to the end of it's stroke, definitely gonna have to have a good surround. and yes I did figure in efficiency. we turned 300 watts into horsepower, and then converted it to force, and then to psi. Which company do I work for? Fluid Power Institute the enclose won't be tuned to 25hz, we will be playing 25hz sign waves. I don't know how much output we will be getting but it'll be neat and free [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG]. I have to see how fast we can get a bigger cylinder to cycle. [/QUOTE]
