(...) Two reasons. One, using a motor didn't occur to me. ;) Two, I don't have any rotation sensors either. I'm also unsure how I could use a motor to tilt and raise at the same time, though I don't think that's a movement needed very often. I could (...)

(...) [snip] (...) Ah..., but you don't really need the back and the front controlled by pistons do you? I would think that keeping the front hinged and the back actuated would give you what you want. With two pistons ganged together, you can (...)

(...) Yes, you're right - two switches would have been entirely sufficient. I just wanted another switch so I could add a release valve, that's all. :) I think originally I wanted something in there so I could bypass the tank and pump directly to (...)

(...) They work for me now also. (...) I guess I was curious why you used pneumatics. I would think a motor/gear/rotation sensor would give you very fine angular resolution and variable speed. You also would only need to control either the front or (...) (21 years ago, 6-Oct-03, to lugnet.animation, lugnet.build, lugnet.technic)

It seems like a front switch and a back switch would be sufficient. It (...) (21 years ago, 6-Oct-03, to lugnet.animation, lugnet.build, lugnet.technic)

(...) Yeah, it does somewhat. One thing that helps is not to pressurize the tank all the way. If there isn't much pressure it doesn't "jump" as much and helps keep increments small. Another thing that's helpful is not to flip the switch all the way (...) (21 years ago, 6-Oct-03, to lugnet.animation, lugnet.build, lugnet.technic)
