hhey guys,
since its my first year, i went on to youtube to find clips of last years compet…As i was searching thro this videos… i foudn this found … and laughed my head of … 3 victors blew! 
that must of have sux majorly
600$ down the drain
Wow. We’ve only ever blown one speed controller, and all it did was smoke a bit and send off some tiny sparks. No noise or anything like that.
EDIT: I forgot to post this for you; team 108 has an archive of a bunch of videos from previous years’ competitions. Here’s the link for last year: http://soap.circuitrunners.com/2006/movies/
Yea, we had two victors blow on us last year. It was a problem because only half of the functions worked till the replacment victors came in from ifi.
I cant say we have ever blown a victor, we have blown a few compressors in our time, 3 to be precise.
We’ve blown one Victor in the one year I’ve been with 68. I’m sure many people saw the public service announcement: http://www.chiefdelphi.com/media/photos/24374
I was not fortunate enough to witness this event…dang.

Speaking of giant electrical shorts…
I wish i could have gotten a picture of it but i was too busy trying to minimize how much I got burned. :ahh:

During an off season competition, we burned out a victor so badly that the inside electrnoics were indistinguishable to lithium grease… Except for the smoke that rolled off of it.
You all know the moral of this story: Electronics work by their magic white smoke, so don’t let it escape, or they won’t work anymore!
My favorite short story was at work when we were trying to jump start one of our 2 battery delivery truck with a 6 battery volvo semi truck.
The driver of the semi had a crowbar in his hands, fumbled it into his battery compartment, and welded it across the terminals. One of the cells ruptured, battery acid everywhere, fumes, fire dept, bla bla bla.
I love Albertsons.
Ow… that’s gotta suck…
Hope it dosent happen again
Its very easy to do. The capacitor in the middle of the victor is electrolyitic which blows up if you hook the power up backwards or hook the power up to the motor. Its rather quite spectacular. Not to mention the fact that the Mosfets themselves are very fragile to static shocks.
I did that once. Made the machine shop smell real bad, as Dillon probably remembers… :o
Sorry to tell you, but that was only one victor.
We’ve smoked a total of three in 6 years. Always painful.

1 or 3 … doesnt matter… that must of sucked majorly!! i wouldnt want to be touching 1 of those when they explode! gave me a good laugh…wait is that bad luck:|… i sticking to programming:eek:
haha…we blew 3 victors while practicing with our old equipment…lol…it was pretty funny…ya…
Our teams only blew one, two years ago we had just finished the wiring and were beginning to test the programming. One started sparking and smoking, we had a laugh… and a bit of a fright luckly we had two extra. I cant rember what we figured made it die, but I think it was metal shavings shorting the capacitor.
We’ve blown a few but the worst situation was a demonstration to some elementary school students and the robot drove at them going full speed, but of course our amazing electrical guy, R2, knew something was wrong and tackled the robot,literally, and turned it off. That was pretty intense.:ahh:
I actually hooked a Victor up backwards last year. When we turned the robot on i heard a “WHRR-CLICK, WHRR-CLICK” noise. Our breakers tripped before any damage was done, so we were lucky. However, this year as a training exercise, we let our rookies take apart last year’s bot. One of the rookies used a power drill with a Phillps bit in it and tightened the screws so tight that they broke off at the head. That was bad.
