  • Not OP.

    That sucks. Especially having to make poor people financial decisions, you often can’t afford to make changes that will save you money in the long run. Been there done that.

    Still, there may be some things you can do to save electricity.

    Cheapo line meter. I use one on my well pump. It shows usage over time. You can figure out what’s using the most juice. It does 200v as well as 110 and clamps on. Does have to be wired in to for it’s power supply and ground.

    Also, Kill-a-Watt clones. $9.99. Shows you how much plug in things use.

    Offhand things that might help:

    • Hot water heater on a timer and turn down the thermostat. There wil be bitching.
    • If you have an electric stove, inductance stoves are supposed to be the most efficent, but you probably can’t afford one. Electric kettles for boiling water probably beat using a stove to heat water.
    • Use a kill-a-watt to figure out what is using juice when appliances/TV/PC/etc. is on standbym
    • Check freezer temp, it may be colder than you have to have it, turn up the thermostat.
    • Check anything with a motor that plugs in with the kill-a-watt, like box fans to see if they’re pulling too much juice, when the motor bearings get shitty, you’ll pull more over coming friction.
    • Use that clamp meter to check things like whole house blower fans, bathroom fans.

    Good luck.

    I don’t give a fuck if it summarized the specs correctly. It’s been proven to be wrong often enough that trusting it to be correct when dealing with life and death issues is foolish.

    I searched a basic spec to get a link to a manufacturer spec list. The bot offfered to vet my setup for safety. It seems you’re suggesting that it’s a good idea to listen to a chatbot for high voltage safety advice.

    I’m not the one with the comprehension issue here.

    I didn’t ask for high voltage safety tips from a chatbot. It offered them. If you don’t think that’s dangerous and wildly irresponsible, you’re being disingenuous at best and willfully ignorant at worst.

    It’s not me that’s going to be killed. it’s people that don’t know enough to not trust a fucking chat bot. Do you really trust a bot to explain ground loops, isolation transformers, and floating test equipment? If so, I feel real bad for any kids you might be training.

    Fuck ‘gemini’. I don’t trust a glorified chat bot with life and death advice. Don’t be simping for a chatbot ran by an objectively evil corpo.

    I don’t care what the actual max voltage is. That search was a shortcut to find the manufacturer spec summary while looking at third party probes. Not ‘gemini’s’ summary or anything else. I don’t want electrical, romance, or life advice from a chatbot. I want links to relevant resources.

    This just looks like you searched for a term where you knew the google ai will give some output so you can post here.

    And there it is. What’s your agenda? Be honest.

    Never ever did google point you to a specific page of a manual when searching for some value of said manual.

    That’s a fucking lie! You’re lying.

    I was drinking my coffee, having a lazy morning, researching the capabilities of my new-to-me scope while sitting in my study. Scope is in a different room and didn’t come witn a paper manual.

    User manual, programming manual, and other technical docs are in the reference section of my self hosted library which is currently down, sd card or the board is on the fritz. (Calibre runs best with a desktop environment so it’s on it’s own little orangepi board running ubuntu or something in a gui that I remote into.)

    Looking at third party probes and wanting a quick reference for the input specs. Wondering if I can get away with a 50ohm bnc cable to resistor for the external trigger or if I’m better off grabbing a cheap probe.

    I’m not the one being dishonest and searching for something like this is perfectly reasonable and shouldn’t result in a personified bot trying to help me fuck with lethal voltages. That’s fucking crazy and defending that is a hell of a choice on your part.

    Are you being deliberately obtuse, trying to ‘win’, or an llm fanboi?

    The scope isn’t even sitting in front of me. I’m just casually investigating the tooling. Looking at cheapo generic probes, wanted the manufacturer spec sheet/sales page, not the full manual. Used to be, a search like that would return a link to the manufacturer’s page showing specs and documents on the product. Instead of going to rigol’s site, using their shitty search or selecting submenus. It’s not me that gets killed with a search like that, it’s someone who doesn’t know what they’re doing.

    It’s a shortcut for pulling up the manual, 240ish pages long. I’m looking into probes, not currently fucking with 300 volts. Used to be, ask for max specs on a component and get a link to the manufacturer’s or sellers summary.

    I do appreciate your shitty tone and assumption of my ignorance. While I try and stay under 480V grid power, I do occasionally have to mess with it in a professional capacity. I’m safe, but someone who doesn’t understand what they’re playing with gets a free ride on the lightning.





  • Interesting. You found more than I was able to. Thank you very much!

    Given the fold of robe/toga, it does make me think of a Roman senator or lawyer. I agree, Caligula doesn’t seem right. You very well might be correct about incorrect attribution. A Renaissance sculpture book from the period might turn something up but I don’t have time or access.

    I’ll choose another model for that section of the book. I’m still fighting David’s lips. Those ever-changing curves are deceptive as is the total lack of symmetry.

    I guess it’s a mystery for now.





  • I’ve not worked with infrastructure PLCs but have some familiarity with industrial PLCs.

    The mode switch probably actually is an effective countermeasure. It’s common to leave machinery in Setup Mode all the time as you can’t change the program or parameters in Run Mode. I.E. you usually trust your crew not poke buttons they shouldn’t. Only in large factories do you find Run Mode being used, even large shops often leaves it in Setup.

    As to gateways and firewalls, the amount of machinery exposed rawdog to the entire interwebs is truly frightening. A lot of industrial equipment have exposed ports that are completely unsecured. Think RS-232 style comms that allow program and even parameter editing.

    I would imagine that many sewage trearment facilities are even less technologically sophisticated than a medium size machine shop.




  • You can often fix membrane switches using conductive paint. Link to example. $11.

    The PCB will have a pattern of traces under each button that are interlocked kind of like fingers that don’t touch or two large pads near each other. The button of the membrane has a conductive patch that completes the circuit between those traces when pressed.

    Usually the conductive patch is what fails due to wearing off. So you just paint on new patches on the memnrane. If the traces are worn, they can also be repaired with copper foil, solder, and careful work with an exacto knife. I’ve even seen aluminum foil and super glue used as a temporary fix on the membrane.

    I would probably make this a an Old Man and the Sea project if it were mine. It’s just so old, it needs to keep going.



  • It seems you’ve thought deeply about this. I’ve done so as well.

    It really fucking freaks me out that such a large chunk of our society is detached from objective, verifiable realty. A fair amount of what they believe is pants-on-head crazy vengeance fantasy. Another big chunk has spooky parallels to literal Nazi propaganda such as the Protocol of the Elders of Zion, it’s so similar that it’s obviously just borrowed. It’s shocking that more people don’t see it for what it transparently is.

    I have no clue what can be done about it. I don’t know how society heals this or reinforces the value of facts, sanity, and critical thinking.

    You got anything? Any thoughts about where we go from here? How to unfuck their heads? Where does this end if they aren’t deprogrammed? How long will we be trapped in this?

    Genuine questions because I ain’t got a fucking clue at this point.
