  • “whatever you do don’t forget to check the big tab is on the left and the little tab is on the right, even if you get it backwards it won’t close as a safety precaution.”

    Gets call of machine not working in another country, sends out consultant.

    Big tab is on the right, little tab is on the left and the entire tray has been forced into position because “it wasn’t closing properly so we had to apply a lot of force”

    Professionals with confidence are the absolute worst, I tell ever consultant or technician that comes into my lab “I’ll be in the corner if you need me to grab you any supplies or coffee, do you mind if I ask questions as you go so I can have a better understanding of what’s going on with this magical box”. I like to think they appreciate me.





  • Did you run the line under ground or through conduit? Disconnect it from both sides, attach string/fishing line to one side, pull cable out of conduit on the side without the string attached. Detach string from either meet cable, reattach string with Ethernet cable and the additional cable (speaker cable in this case), pull string from the original side until both cables make their appearance.

    Outside of walkie talkies (have you considered walkie talkie? Maybe put an antenna outside of the shop?) this is the simplest way to do it (imo, but I don’t play with raspberry pi’s)



  • From Amazon, I found “IS543 5/4/3 WIRE INTERCOM STAT-PLAST”

    It’s similar to what we had growing up, 1 in the shed, 1 in the kitchen 1 in the game room, push the button of the location you wanted to talk to, only 1 direction of communication at a time, over.

    I feel like you’re making it way more complicated than it needs to be, why would you involve a switch or processor when you’re just carrying sound waves? You don’t even need a modulator, it just needs to connect a microphone to a speaker like cans on a string. Is it the highest quality? No, will it record your conversation for posterity? Also no. Will it let you tell at someone to get their asses in for dinner, absolutely

    Sorry, what?? There are no hydro thermal vents at the surface of the ocean???

    Fucking biologist needs to go back to school.

    There’s no life at hydro thermal vents at the surface of the ocean because there are much safer and more reliable ways to get energy, but there are absolutely areas of active geothermal extremes at the surface of the ocean.

    Hell there are hydro thermal vent remnants in the coastal ranges above sea level.

    What does engulfing the earth mean to you? The mass of the sun expanded to a body 1 au would not be very dense. My money says the earth would continue to orbit “inside the sun” for quite a while, but the orbit would degrade more quickly.

    But yes, I argue get them out of the earths gravity well and let Newton handle the rest, no reason to propel them in any direction, eventually they’ll get to the sun.

    You are making 2 opposing assumptions there, 1) there is nothing to bump into in outer space, the earth picks up 43 tons of new mass every day.

    1. the earths orbit would decay, the earth is absolutely massive compared to the amount of mass gained, and also off gasses a significant amount of mass every day.

    If orbits don’t decay, why do even high orbit satellites need to make elevation corrections?

    If you put a small body into outer space it would absolutely be (slowly) effected by the miasma of particles out there.

    And let’s not forget we don’t have a time table for reaching the sun, and we aren’t aiming for the middle of the sun to see results. And as you approach the sun you will bump into more and more particles as they too are being drawn around the sun.

    It’s an easy talking point from the Internet and high school text books, it is disregarding of many actualities of our universe. It would be true if the sun were an infinitely small point on a 2 dimensional plane with a perfect lack of friction.

    And while for instantaneous results it would be easier to get something out of the sun’s gravity well rather than hit the exact middle of the sun, practically, if you have time, and you don’t actually need it to hit dead center of the sun, it’s much cheaper and easier to incinerate something proximal to the sun than it is too send it out of the solar system.

    Also let’s not forget gravity sling shots work in both directions.
