  • Measured voltage is completely dependent on what is used as a reference. If you were to measure the voltage of a power supply set to +30V with a voltmeter whose leads were backwards (ie positive on the voltmeter connected to negative on the power supply, and negative connected to positive), then you would measure -30V. All this is to say that if you connect your 30V supply “backwards”, you will have -30V. Now, there may be some circuitry in the power supply that only allows current in one direction, and it could be that it’s able to source a different amount of current than it’s able to sink, so be sure to check its manual.

    I’ve tried -12V from psu i’ve got lying around but it didn’t work.

    I’d advise caution against arbitrary decisions with electronics — both for your own safety and the safety of the equipment.
















  • Even if the police were functioning well enough to act to stop a school shooter, there is still the issue of time — it takes time to arrive to the scene to respond to the threat. A competent on-site security presence would be a good first line of defense. Think of a time sensitive scenario like a home invasion — would you rather have the means to immediately protect your home, or would you rather wait for the police to arrive? What if someone attacks you on the street? Would you rather have the means to immediately protect yourself, or would you rather wait for police to arrive? In some cases, no matter how competent the law enforcement is, it’s simply impossible for them to respond fast enough.



  • it is apparent that you trust the rich too much

    Why?


    they want to keep you down to add millions more in their pockets and then they move to take away more human rights.

    I do think that it should be assumed that a business only seeks to increase profit, but I have no issue with an business making profit given a fair and competitive market, as a fair and competitive market (ie capitalist) is not zero sum. As for regulating businesses to prevent them from exploiting things to the detriment of society, I would advocate for a Georgist philosophy.
