How to remove stripped laptop screw?
    1. Strong down force with the appropriate screwdriver (looks like it started out as a Phillips head) while turning the driver with a wrench. You need a square shaft in your screwdriver or clamp with vice grips.

    2. Same, strong down force, but use a square driver ( Robertson screw). This can also be accompanied with a wrench.

    3. Drill it out. This is pretty much the last resort as you will use a drill bit about the same size as the threads which will pretty much take the head of the screw off as you drill into the threads. The threads probably won't come out but you will at least be able to open the case. I have had very little luck with screw extractors and they probably don't come that small.

    Strong down force is the main thing I have found to work when breaking loose pesky screws. Pushing down hard enough to prevent the bit from skipping to the next slot

  • how the heck does FM work,?

    Kind of an ELI5, but I tune a radion into a specific frequency to listen to a station. If that frequency is constantly being modulated (changed), how is the radio not going in and out of tune? I expect it is finding a way to measure multiple frequencies around the tuned station and decodes the data from it's deviation from the tuned frequency?

  • There has always been a pretty large gap between Perez and Max in terms of performance. It's been speculated that it is more a matter of the competition's cars getting faster than Perez's performance declining. They have found a way to catch up with Red Bull car and only Max's skill is keeping them ahead.

  • Have you ever been to a movie so terrible that you saw people leaving the theater? Which one was it?
  • Both reading and watching The Shining really helped me appreciate what Flannigan pulled off in making Dr. Sleep. He kept all the lore and nostalgia of Kubrick's movie and also found a way to put back most of the King material that Kubrick had abandoned.

  • How come running hard (especially when out of shape) makes your lungs feel like they are on fire?
  • Acid buildup in muscle tissue. Here is an article that explains what is happening:

    Esit: I originally said that your.muscles are creating waste chemicals quicker than your bloodstream can handle causing those bad chemicals build up locally. While this is true in a broader sense, I think it is more nuanced that that. Reading the article should give a better explaination

  • DC Theory: negative voltage

    I'm trying to understand what's happening in this circuit:

    I------------------T1 (+333V) I I I R1(10K) (pos) I 1000V I------------gnd (0V) (neg) I I R2(10K) I I I IT2(-333V) I I I R3(10K) I I I-----------------IT3 (-666.7V)

    I am learning basic DC theory from reading and sometimes I come across something I'd like to ask a question about, so:

    1. In the above circuit, without the ground, the voltage across all components would begin at 10V and finish at 0V. By adding a ground, I'm basically saying "here is 0V" and everything gets redefined in reference to that point and I end up with a 10 volt circuit with +3.33 as it's highest voltage and -6.667 as it's lowest.

    2. The electrons could care less, they still flow from the anode to the cathode of the battery under normal conditions, going from the highest potential to the lowest.

    3. This example was only used to demonstrate voltage dividers. It revolved around worker protection present in aluminum processing. Each machine is in series and mobile grounds are used nearest the machine a worker is using. I assume that this allows the worker to have the least exposure to electrical shock as they are also at ground potential?

    I actually think working though these questions has cleared everything up, but please, comment on anything I got wrong.

    Also, sorry about the crappy drawing, the autowrap in this editor really made things tough to format

    Thanks!
