re: My Algodoo design spins endlessly each time I re-build i

Thanks Chris. Yep. I know about the Algodoo hinge issue. If you put a hinged component that overlaps slightly with a component with the same collision level, the thing will take off like a rocket! Both you and Fletcher have convinced me a working prototype is the only sure thing. Prior to that, I wa...

re: My Algodoo design spins endlessly each time I re-build i

Thanks Fletcher. That's the advice/insight I was looking for. It helps knowing that "zero runners" are not uncommon. In my experience, air drag in Algodoo causes strange things to happen. A simple balanced lever will go "out of balance" when air drag is on. I guess that says some...

My Algodoo design spins endlessly each time I re-build it. A

I have been tinkering with Algodoo for years and this is the first time I have encountered this situation. I understand that simulation applications have flaws and can give false results. I am hoping for guidance on how better to test it. The design is EXTREMELY basic/simple and fits with most of th...

Another Algodoo/Simulation software question

My latest Algodoo design ran all night (10 hours) with no degredation in speed/momentum/energy. This is a first for me. All other attempts (over years of using Algodoo) have either failed to turn more than a few times or they begin to show some degredation in energy/momentum immediately. However, wh...

re: Algadoo advice please

Thanks Tarsier. I have ZERO mechanical skills. Attempts I have made in the garage have been wobbly embarrassments. The design I am testing is REALLY simple. Do you use an simulation software? Can you recommend one that is easy? I tried one that a lot of people here use (forget the name) and it was w...

re: Algadoo advice please

Here is a better question:

I use Algadoo because it is so easy to learn and cheap. Is there a more reliable application that fairly easy to use and not very expensive?

Thanks.

Algadoo advice please

I have been using Algadoo for a few years, and can usually identify why my wheel is spinning when it shouldnt be (eg. two a surface colliding with a hinge, etc). Now I am trying out a design I am really excited about, and the thing has been spinning for two hours. I stop it (manually) and it sits un...

re: False Positives with Algodoo sim software?

Thanks Chris.

Is there any way to compensate/adjust for the pivot point variances? I'd rather not spend the money /time converting this into WM2D, and I want a fairly good idea about it's merits before actually building it.

re: False Positives with Algodoo sim software?

Thanks for the info!

Is WM2D much more complicated to use? (Algodoo was fairly easy)
Is there a free trial version?
Can I import my Algodoo file into WM2D?
Thanks again.

False Positives with Algodoo sim software?

Has anyone here had experience with Algodoo sim software? If so, can you point to reasons that it would show, incorrectly, that a wheel design is self sustaining. I am reasonably certain that the issue is not with my friction settings. Also, is Algodoo considered a reliable simulation application? I...

Simulation Software - Any good?

I meant to include this in yesterday's post. Having virtually no mechanical skills, I am considering using the simulation software that some of you use (and post screen shots from). 1) Are they any good (ie can they really give a clear indication of how a device will behave)? 2) Are they terribly di...

Am I the only non-craftsman? Curious.

Like many of you, I really, really, really think I have figured out Bessler's design (Really! ). My design is on paper (where it appears to be absolutely full proof). But every attempt that I have made to start working on an actual device is laughable (everything wobbles, tilts, or falls over!). I a...

Questions from a novice...

Please forgive my questions if they are naive. I am curious about the usefulness of momentum, and if there is an "inner" and "Outer" track ratio for creating an overbalanced wheel. Question 1: Picture a wheel..with a single weight at the top (a distance from the axle). When you p...

Just for the fun of it..... What would you do if your design

For the fun of it, give me your thoughts... What would you do (right now, this minute,, and then over the next few days) if that prototype you finished a few days ago started spinning with only a minor push. After a few minutes of watching it spin freely, and not wanting to jinx the thing, you decid...
