I'm kinda wondering where you would fit in the hunter unless he's hunting for dolphins, which I DO NOT approve of. I have been thinking about something along those lines though but to build a functional dolphin while keeping the round shape just seems impossible. I need more than a month to perfect a build like that. -
Still, I'd REALLY like to see some detailed pics of the track and car. All the other threads about coasters are very vague as well. If you don't want to show us your stuff, then why tease us like this?
-
Still one month left to enter I assume? I want to be in this contest but I just don't know what to build that doesn't include stuff with wheels At least there's still time....
-
How do you keep the car on the track?
-
It looks old. And I have to agree that something is off about the truck, the wheelbase seem too small
-
Couldn't you just use it in combination with an old touch sensor that have a built-in resistor to make a continuously flashing light?
-
I've got 6 blue of these old touchsensors from the old Cybermasters set and all of them still works when I tested them on my NXT.
-
As I said, I dunno. Something just seems a bit off and I can't quite put a finger on it. I wouldn't want you to touch the lifting mechanism as I think it's a brilliant design in such a small space.
-
Yeah, really nice work, excpet I don't think the wheels fit on that wagon. I can't exactly say what it is, but something is off about them. I think the wheels might be too wide or too far apart.

Jovel uploaded an LDD file: http://www.brickshelf.com/gallery/jovel/Pnuematic/auto_valve.lxf My expectations very pretty accurate. Sliding 8t gear with a steering axle on the bottom.
-
The length of the tubes has to be somewhat the same length of course. I know that already. And nope, no mindstorms, it weighs way too much and takes up valuable space for the big motors. I was just looking for an autovalve solution that is fail-safe with basically no continuous wear on the components at any given time.
-
I see, that is actually very clever. It's not what I'm looking for though as I need 4 closed loops, with 4 sets of pump/valve/cylinder to make sure all cylinders travel at the same time. You'd also still need some kind of autovalve to turn the slave valve first though. Neutral position doesn't matter. Who uses neutral in an automated system anyway? EDIT: I also build my 3D model IRL. It works fine except it doesn't slide as good as I imagined since the worm gear interferes slightly with the sliding rack. It still slides to the end every time though. I'm not sure if I should replace my current autovalve with this one since it's more than twice as big, but the continuous stress on the 8t gears are much much lower.
-
1 regular sized cylinder can easily handle 4 valves as I've found out. However, where would the excess air go when the cylinder has reached maximum length? What is so great about this original design is that there is no continuous pressure on the 8t gear at all and the fact that it can just run indefinitely. What I came up with however is very bulky but only because I'd need to place the valves somewhere. The core idea is only 3 studs thick and could be implemented basically anywhere where it's possible to place a valve underneath it.
-
Those warnings are only for people who don't know how to charge a battery properly.
-
4 valves are really hard for 1 8t gear to turn if not impossible. You'd also need a lot of pressure on a cylinder to turn them. Would you mind building a prototype of what you mean because I'm not entirely sure how it's going to work.
-
For my own purpose I need a 4-valve switch. One 8t gear can handle 2 valves easily but not 4 so I came up with this: The model is basically mirrored in both the x, y and z axis. Pink color indicates the steering for sliding so it won't make any funny slides. Orange color on 3x0,5 liftarms means both sides are linked, hence the 16t gears as well.
-
In essence, I believe that this is just what he did: Made a sliding axle
-
Oh ok, sorry for the inconvenience
-
It was just an example for the simple and very basic "IF" command You'd have to replace the condition for if to be true or false depending on the way you program it
-
Couldn't you just use an "IF" command instead? Like: if motorlimit = true; motor = 0; else; motor = 100; end_if;
-
Am I right in assuming that it's 500 pieces per model as in 1500 pieces all together?
-
BUMP I'd really like some pictures of the internal of that autovalve Jovel. That is by far the best design I've seen so far and I want it for my airplane to make less stress on the gears.
-
This is because there is a current resistance component in your battery box. You would need to get a hold of some old battery boxes or the RC Unit for it to work properly. Also take a look at this thread: http://www.eurobricks.com/forum/index.php?showtopic=87319&hl=battery
-
It's going no where. I haven't been working on it or anything else since my last post at all which is basically exactly 6 months ago. I've got other stuff in my head recently and need a nice break.

It looks really good. Does it have a bonnet as well?
