Algodoo

I missed the point above when I first ran the scene. Now that I understand, I think it is a very cool scene. The gears are camouflaged when stopped at any angular position. Nice demo.

See Two Synthesis Methods for Non-Circular Cylindrical Gears for the math. Save the scene with a .phn extension and then open it with a text editor to see the code. The simple explanation is that you create a shape and a hinge and then the second shape must have a surface that rolls without slipping on the first shape and must have a perimeter that is n2/n1 times the first shape's perimeter.
The circle teeth spacing should be the length of one side divided by an odd number. The phasing of the gear teeth of the first gear with respect to the second needs to be correct for smooth operation.

Logical OR

Nice work.

Thanks. It took me quite a while to figure out how to do this.

At this point, I could make an asymmetrical gear generator that would take any polygon, and if given a center to center distance, create its conjugate and then add gear teeth. I did make an asymmetric shape and its conjugate in flames, but I used a spreadsheet to generate the coordinates instead of Algodoo. I am not sure if I am going to make an asymmetrical gear generator yet.

Nice work. Looks good. Runs well.

I also made one. Harmonic Drive

Well done. This must have taken a while to make.

pnvv,

Thanks, but I think I need to beef it up based on Kilinich's comments.

Kilinich,

I now see what you mean about light bodies. I will try to fix that.

I also agree that spawned geometry should be inside the engine, which mine is, until it exhausts. Spawning geometry outside the engine doesn't work so well.

Thanks. I suspect you can beat this, so I'll just sit here and enjoy being top dog until you do.

This does not work on my computer but Kilinich's scene works even at 10 kW/kg.

Now that's one strong engine. I'm not sure if this qualifies. You will have to check with pnvv (pnvv, your check is in the mail). The reason I question whether this engine qualifies is that a spawn engine's spawn geometry usually presses between 2 or more machine elements in order to push them apart whereas in a rocket engine the spawn geometry pushes between space and one element. This looks like a rocket engine to me. pnvv explicitly stated "You can't just build a rocket". All previous entries have been engines where the spawn geometry presses between two machine elements.

"When I use a word," Humpty Dumpty said, in a rather scornful tone, "it means just what I choose it to mean - neither more nor less."

Thanks guys.

Ferris is a little disappointed that he is no longer the fastest.

Nice work. Elegant solution.

I can morph shapes and colors, but I don't know how to morph textures. If I knew how to warp textures, then maybe I could morph them.

Nice effect.

Thanks.

Impressive.

Nice work. I see how you did the track stilts. I didn't know you could do that.

Thanks Xray.

Yes, all aliens from planet Glork can see magnetic fields. This is what earth's magnetic field looked like when I arrived.

I have 654 non-entered scenes, so I'm running about 50%. My motto is "Quantity B4 Kwality". 32 scenes with 50 hits each = 1 scene with 1600 hits. Also, if you update your scene with minor changes, then you can trick some users into downloading it twice. That's my big plan anyways.

I'm going insane. Nub Nub, any ideas as to what might help.

Thanks Nub Nub.

Good scene. It seems obvious to me now, but I never thought of using spring ends as hinges.

Thanks.

Nice work. If you are familiar with scripting, and would like to convert to x-y motion, then feel free to use the code in Robot Arm II

I see you are new to marble races. This scene really needs to be in the "Marble races" group, otherwise Xray may delete it. Good work, I can't wait to see your next marble race.

Yes, sometimes it's better to start with a clean slate.
