Every tech guy knows that all electronic components run off of the Magic Smoke. If you break a component and release this smoke the part never is able to work again, it's like the soul of the component. This video is horrible, torturing that poor component and forcing it to release its smoke.

@Afrotechmods 10 жыл бұрын

They are meant to be used with electric vehicles, and unfortunately I don't have a Tesla lying around so it might be a while before I can show something practical with them!

@jomunoz 10 жыл бұрын

Ford is using super capacitors on a prototype vehicle, the car runs on gasoline but the super capacitor runs an electric turbine that prevents turbo lag at low rpm's. The result is turbo power at any rpm.

Afrotechmods just dont make them tooooooooooooooo long. Gather a bunch, make them quick, and then like boom, baam, click, etc, with beethoven in the background as they blow and burn to the music. btw, idea just as we are talking about failure modes. Why not a video showing each failure mode for most components. Like caps drying out, and lossing capasity with high esr or drying then short circuiting, Too much voltage causing a puncture in the isolation. etc. Diodes burning open or SC. And maybe an scientific explanation of why or what caused it.

this remindme the prank that is done to the new employees in the repair workshop. But, with me, was a fail, because I catch the prank before I react as suppose to be. The prank is, lets the newbie repair that TV PCB, so when the newbie is focused in the task, doing measures with the pcb connected to the power grid, sneakily blow cigar smoke from under the PCB, lets the newbie to thinks that some component is burning and react desperate to disconnect the it from the power.
