This is what I have been told:
The camera wire somehow shorted out and caused an arc that caught their nylon fabric stuff on fire. The fire went out quickly but it still smoldered inside the electrical box. When they lifted up the cover they released the magic cloud. After they got back to their pits everything was fine and nothing (except the fabric) was damaged. Their camera worked fine.

Our pits were right next to them and they were examining there anderson battery connector. I believe that there connector was lose and the leads started to touch and after a while everyone knows there is the mysterious electrical smoke. When they brought it back to the pits they had to replace a connecter or just pop it back into place. Everyone thing was smoked and chared but i believe they had pretty good luck throughtout the weekend.

We've smoked 2 of the fisher price motors so far this year, expecting at least one or 2 more before its all over. They're running the roller system full out so anytime we get a jam they tend to overheat fairly quickly, no flames.... but just a smokey burning smell.

That's impressive! What burned? Last year we had a bad soldeir job on a pwm short, It fused several other pwm cables together and melted our wire wrap but it was nothing like that. I'm going with a short (possibly a motor of victor burning).

There was another bad smoker at GLR along with 1189. I don't remember who it was, but they had the fire extinguisher ready.. and it was red. Both smokers had lovely smells...

That was the most magic smoke in awhile.

One of the teams at Florida regional started to smoke in the middle of the field. I am not exactly sure which team it was. They burnt a fp.

Arefin - The team that had the release of magic smoke at UCF was us in Q18. We burnt out two FETS on one of our speed controllers for the drivetrain while pushing two other robots. The ref onsite said he knew the smell and said it had to be the fp, but on return to the pits, I confirmed that it wasn't the FP, I had rewired everything that morning and knew I hadn't connected it that match. It wasn't much magic smoke from the speed controller, but we hit disable before further damage/smoke could occur. Although after this I'm slightly uneasy about the 40amp breakers reliably popping before the speed controller fries...

(As a side note, we had a lot of bad electonic luck in UCF.... We turned on the robot after uncrating it and all of the 5 spikes were dead. They were working perfectly when we shipped...... IFI rep personally tested them and seemed just as confused as us that all 5 were dead and all the other electronics were fine.)

If memory serves me correctly, I seem to remember team 59 (RamTech) smoking a bit after getting on the ramp... no idea what match it was though.

I remeber that, but I dont know who it was. I know 47 blew out a drill motor, or so it appeared from all of the magic smoke.

While working on the GTS, another member wanted to test the shooter programing so we simply "unplugged" the pwms to the drive system. We carelessly left them there and didnt move them so when the programmer turned on the robot....poof...lots of magic smoke form the pwm cable that contacted the 12v power to the victor. It comepletey melted the pwm cable...luckily we had some of the Y-pwm cables laying around.

which motor are you referring to? we didn't have drill motors this year

[Dillon Compton]

Last year at nats our battery lit on fire...we never figured out how/why. We think someone may have dropped it at one point...

burned all of the electrical tape, and melted the insulation off about 6 inches of the 6awg leads. Thank god for the brave ref with good reflexes who grabbed the battery and, I kid you not, threw it a good twenty feet.

Thankfully this happened about 2.5 seconds after the match was over.
