Re: Problem with our Victor?

Your Victors came with the wrong topology... They are supposed to work in an H-bridge, yours had a short "I-"bridge. Call IFI and claim DOA!

Re: Problem with our Victor?

You have too much whitespace between the sections of the victor. Remove it and apply duct tape (not masking tape) to seal it.

Also, the Coriolis effect may be causing the electrons to orbit the central capacitor in the wrong direction. Did you obtain this particular speed controller from the southern hemisphere?

Re: Problem with our Victor?

There is no problem at all with this Victor. It is simply undergoing mitosis. Wait a few days and you should have two nice new Victors ready to go. Isn't that how IFI does it?

If you simply can't wait that long, I suggest you use the bandsaw to induce mitosis in your RC, so that it is at a similar state of division and better able to communicate with the speed controller.

I don't see how this could be a hardware problem, must be a software problem.

It looks like you have configured your Victors for a Beowulf Cluster approach. Be sure that you load an OS that supports it.

It can't be a software problem, because C ignores white space!

Also, the majic smoke must be blue! Its always blue majic smoke!

Re: Problem with our Victor?

This thread gets an "A+" From a high school physics teacher! It's what i've needed after 6 long weeks of building!

Now about the "problem"... All our Victors looked that way when we pulled them out of the box 6 weeks ago. They didn't work for us either. After much thought and observation we deduced that the spin on our electrons were backwards. In order to compensate for this, simple replace the terminal posts with left handed screws and it will work perfectly!

PS: that whole mitosis stuff is a bunch of garbage anyway. Those darned Biologist think they are "real" scientist when they only practice applied chemistry and everyone knows that chemistry is really applied Physics. trust me on the this: change the screws!

Re: Problem with our Victor?

You should try applying anti-matter to the Victor's surface. That should give you enough pure energy to run your CIMS for the entire competition. Just make sure you don't wire all your CIMS to this one Victor, that's against the rules!

Re: Problem with our Victor?

You know, I think Don Rotolo is right, I can see some electrons leaking out in one of the pictures. What you need to do is go find all the electrons that dripped out and return them to the module. You might have to go to a local electron supply depot to get enough to completely fill the device. Then you will need some Acme Electronik Leak Sealer with testing dye. Use according to the labeled directions and certainly wait the required length of time for it to cure. I believe it may need a vacuum of at least 40 inches of mercury for the curing process. Then you will need a variable voltage source, and starting at a very low voltage (1x10^-10 volts) and slowly advance the power supply while watching for the tell tale electron leak to occur. Most repair stations will perform this in a photographic room with the lights off. If all the electrons leave at once then I am afraid this device may be impossible to repair. Give it a good funeral and bury in the back yard along side Fluffy, the faithful goldfish from your youth.
