Algodoo

Glad you like it, guys!

Algobox doesn't have "channels". That's a YouTube thing.

I discovered if I make the friction of the inclined plane very large (>= 1*10^15) or infinite, then u2 becomes a negative number.

I know, I know..... Who cares, right? Probably no one, but I wanted to bring that to your attention in case you happen to see any issue with that.

As usual, your tutorial scenes are excellent teaching tools!

Quote: "When the boxes are glued to the background, then the sum of the forces in the x (or y) direction do not equal to zero, which they should."

I know what causes that but I'd rather not discuss it because it's a very sticky subject.

You mean "Violet"? She and two guys (Grey and White) sneaked away and had their own private party in the woods. She's going to be grounded for a year when her dad finds out what she did!

Nicely done. Good job!


Suggestion: When the volume is set to very small, then pressure and temperature indicators move high above the normal display area. The user can zoom out, of course, but one thing that you can do to eliminate that from happening is to make the scale logarithmic instead of linear.

Exactly!

Thanks, but I would be the first to admit that it's actually quite silly.

Hello,
The legs do not move because your code refers to local variables (_leg, _leg1, _leg2, etc) which have not been predefined. If you do not define them, then they will not be saved with the scene. There are a couple of ways that you can define a local variable. One is simply by typing the name of the variable and giving it an initial value. You must define a local variable within the geometry that will use it. So, for example, before you save your scene to your computer, define the local variables by typing their name in the text box located in the upper left corner of the script menu. An example would be:

_leg2 := 1.0 (the colon is not required but it allows error checking if you do use it.). Another way to define a local variable is to place it in the "onSpawn" event handler. That way, the local variables will be defined each time Algodoo gets launched by users.

Hope this helps!

Wow! This started out as a simple animation, and is now turning into a full-featured movie with a plot, plenty of action, a little "Romance", and some comedy. Very good job! (Notice the TWO thumbs up! )

I like X-rays!

This was an attempt by Bessler to design a perpetual motion machine. He claimed that it worked, but of course it did not. Only by cheating physics with programs such as Algodoo can you make a perpetual motion machine appear to work.

You must not be initializing the local variables properly. Did you do it exactly as I stated in my first comment? If you did, then it should work because it did work when I did it.

When you enter _leg := 1.0 into the text box at the top of the spring's script menu, do you see the new variable show up in the script menu as a new item? If you do, then you need to SAVE the scene before you upload the edited scene.

If you would like me to edit your scene so that it has the local variables instead of scene.my global variables, I would be happy to do that for you. Because I am an Algodoo Admin, I could do things like that! But I would not do it without your permission.

Yes, it looks like you got it working! And you also realized that because those "_leg" variables are "local" variables, you can repeat them as many times as needed without worry that they might interact with each other. Because they are local, you can define the same name in different geometries.

Good job!

By the way, I test my scenes by downloading them each time I upload a new scene. I found that by doing that I can sometimes catch a bug that I would not see by just running the scene on my own computer. And occasionally, other people might see a problem that I do not see on my own computer, and so I rely on others to tell me if there's a problem (Like I did with you!).

This is a great idea, s_noonan! You might be able to patent it and make zillions of dollars by licensing it to the giant auto manufacturers!

Actually, you DO have a description. I happen to have X-ray vision, and so I can see it.

Thanks!

@jon_joy_1999 - Right on!

@SuperMax16 - There are a lot of issues with this, and because of the fact that it's so simple, and it cannot possibly do what you claim it can do (see my explanation below), I think that you posted this scene just to get some comments, and for no other reason. Well, apparently, it worked!

Here are a couple of technical reasons why this idea cannot work:

1. Those two rectangles that you call "magnets" are not configured to repel each other. The stationary rectangle has its attraction attribute set to 100, which will actually make it "attract" other objects rather than repel them! A positive attraction value causes an attractive force, and a negative attraction value causes a repulsive force. The rotating rectangle has it attraction attribute set to ZERO! Therefore, it does not attract nor repel any other object.

2. You are attempting to make a perpetual motion machine which has been proven over and over again that such a device is physically impossible in the real world. It can be accomplished in an Algodoo scene because Algodoo is capable of defying physics. But of course that doesn't count because it is make-believe.

@SuperMax16 - You said: "There is alot of money to be made in the oil industry, therefore the governemt may be hesitant to use this idea."

The reason why "the government", or any privately owned company, for that matter, is hesitant to use this idea is not because of "a lot of money to be made", but because the idea is technically not possible. YouTube has no shortage of "magnet motor" videos and other such free-energy devices. Some of those videos are nearly a decade old, but I haven't seen a single "magnet motor" in operation in any commercially available device. That's because it does not and can not work. A permanent magnet is not a power source, just as a metal spring is not a power source. But many people simply refuse to believe that fact, and they instead come up with the crazy notion that the big oil companies are paying off (or killing) all of the successful inventors of such devices. There are certain things which Nature does not allow, and one of those things is perpetual motion (aka, "free energy").

Nope. I'll say it again.... Magnets are not a power source. If they were, then of course they would be "better than burning coal or oil". Show me a magnet motor that has been proven to work by an independent engineering firm, and I would be the first person in line to buy one!

Because YOU had to push them together before they repel each other. In other words, YOU put energy into the system. It's not unlike when you wind the spring on a clock. You put energy into the spring and then it puts pressure on the gears to make the clock run. That energy came from YOU, and not from the spring. Get it?

No, of course not. Nothing in the device can some how magically create energy out of nothing. The device has only the energy that YOU put into it when you first pushed it. After that initial push from you, there is no other energy in the magnets or in any other component of the device, and so it will slow down and stop. The "free energy" community will try to convince you otherwise, but to this day, none of them has created a magnet motor that continues to run on its own magnetic "power".

I don't want to ramble on this subject any longer, so I suggest that you do your own research on "magnet motors" and other such "free energy" and perpetual motion devices, especially if you don't understand the law of conservation of energy.

Thanks for the chat, but I'm done here.

Thanks, Wyatt!

You actually applied 22KV to a battery? Where did you get a 22KV power supply that can generate that much voltage?

@Ravenplucker - You said: "I worked on this for ages". I'll bet you did! Holy cow, this is another example of the complex mechanisms that you've made. Very impressive.

Kilinich?? No, I'm Xray.
