On top of that the explanation for pots busting off old rust on the contacts can yield some important design considerations. Show 7 more comments. Active Oldest Votes.

I'm surprised they were able to keep those exposed wires from shorting to each other on a very regular basis if not constantly. What you're seeing are the bare component legs. It was common to have screwdrivers with insulated shafts for adjusting trimmer caps and chokes in such sets, to avoid shorting things out.
With proper layout as we see here the component leads do not touch one another. They are short, stiff, and soldered to numerous fixed contact lugs.
If you look closely you will see that in a few places where a component has more freedom of movement an insulating sleeve has been slipped over a lead. Because everything is open and visible working on these things is a real joy, at bit like working on an old pickup truck as compared to a modern compact car.
On comparably complex manually assembled PCBs, you'd have silk screen to tell the assembly line worker exactly where that resistor had to go — I can only imagine people having a printout of a plan, highlighting the components they ought to solder into place in their manufacturing step, sitting in front of a sorted box of components and praying they don't accidentally mix up these two solder lugs in the lower right corner at each of which 8 component leads end..

All better. Happens in Toy Story 3 : Apparently the best way to get your Buzz Lightyear back to normal after a hard reset is to drop a TV on his head. One of the aliens tries to open a compartment to obtain a bag of drugs. When pushing a button fails to do anything, he kicks it and it slides opens. Note that the hammer only fixes. Felix is trying to break those prison bars, making them even stronger instead.
Korso: She's a little bit twitchy. Hold on. He opens a lockbox by meditating, then tapping it with the edge of his hand. So this may be Older Than They Think. The Longest Day : Capt. Colin Maud: [walking up to a stalled vehicle] My old grandmother used to say, "Anything mechanical? Give it a good bash. Colin Maud: Try it now. Drake: Only works if you bash the right side.
Hudson: What happens if you bash the left side? Drake: Your head implodes. Lev Andropov: This is how we fix problem in the Russian space station! Lev Andropov: Components. Matrix: Come on you piece of shit, fly or die! Eddie: Violence and technology Old joke: A man can't get his car working, so he gets it into a repair shop. The repairmen turns over the engine a few times, then goes to his tool rack and grabs a hammer.
He comes back, pops the hood, gives the engine one quick rap with the hammer, then turns the key and — presto! Engine works. In the joke, The Expert carefully listens to the description of the problem, then takes a look at the wiring diagram, and circles the faulty part in pen and walks out.
Artemis Fowl : The telescreen freezes, and Foaly goes to repair it. Julius hits it to make it go back on line, but that not only fails with the narration making it clear that this almost never works but he burns his hand because the screen gets hot after a time.

Of course it doesn't work, given the circumstances , but it's the thought that counts. Ringworld : Teela Brown activates her sky-cycle's emergency booster at a key moment by fainting and smashing her face on the control panel, thus saving her life. The emergency booster required several controls to be hit in a specific order, at least one of which was recessed and thus much harder to hit accidentally. The other characters take this as proof that she was literally Born Lucky a plot point in the story.
He quickly chants it as he taps his binoculars whenever the image is getting fuzzy. The teacher hits the side, and the image comes into focus. Live-Action TV.
