Hezbollah members wounded in Lebanon when pagers explode
  • I would love to see a detailed technical explanation for how this would be possible.

    I design battery-powered electronics for a living and I can't think of any design that would let a battery explode with the violence these did, let alone on command. Unless it were deliberate.

  • Protests and a major workers' strike are planned in Israel after more hostage deaths in Gaza
  • NYTimes reports that IDF claims Hamas killed them shortly before they were found. I thought I recalled seeing elsewhere that they were claimed to have been shot, but I can't find that source at the moment.

    Of course, how credible is the IDF?

  • Why do big corporations get to claim losses, but small businesses can't?
  • Yes there is a difference, but LLC is a legal concept, not a tax one. The IRS taxes sole proprietors the same whether or not they have an LLC.

    Tax entities include sole proprietorship (default), partnerships, s corps, c corps. Any of those can be LLCs, but they don't have to.

  • Why do big corporations get to claim losses, but small businesses can't?
  • Profitability is just a proxy for whether someone is legitimately running a business, or just trying to save money on their hobby. Businesses can deduct expenses, hobbies cannot.

    So if you are running an etsy store or an engineering company and buy a 3d printer to make parts, the cost of that 3d printer is subtracted from revenue for tax purposes. If your "business" is actually a hobby, it's not legally a business expense and therefore it's not deductible

  • What Donald Trump’s Most Loyal Followers May Have in Common
  • From the article:

    Conscientiousness, one of the Big Five personality traits, is defined as a tendency to control one’s impulses, be persistent, act dutifully, and live up to one’s obligations to others.

    Conscientiousness has been linked to a variety of positive traits and behaviors, such as responsibility, dependability, hard work, goal orientation, self-control, and leadership. Some conscientious people, however, happen to be dogmatic, inflexible, unquestioningly obedient, and intolerant of uncertainty (i.e., they tend to see things in black-and-white).

  • Why did my PLA crumble after 6 weeks idle in my printer?

    I left a spool of eSun PLA+ beige in my Prusa MK4 with Prusa enclosure, which has sat idle since my last print about 6 weeks ago. The enclosure has a PTFE filament feed tube that runs the filament from the spool to the extruder.

    Today I went to change the filament, and it broke apart in several pieces, right at the ends of the ptfe filament feed tube. The filament on the spool itself - within an inch of where it simply separated from the broken bits - I can fold over 180° tight without breaking it. Even the several ~1" lengths of broken bits are similarly ductile.

    Ambient humidity is something like 15% (per my filament dryer) to 30% (per my dehumidifier, which is idle because it's winter).

    Any idea why this happened? I'm curious about maybe interactions with the PETG parts that the broken pieces were close to (that's the only thing I can come up with, anyway).

    Benchtop current sense amplifier?

    Anyone have a recommendation for a benchtop current sense amplifier?

    Sure, there are current sense breakout boards and whatnot. But what I'd like is a convenient device that I can use to instrument a circuit and then monitor its current with my oscilloscope or logic analyzer (Saleae with analog input) along with other signals in the circuit.

    Ideal features might be:

    • Banana jack inputs and outputs
    • Selectable range / sensitivity / sense resistor
    • Isolated measurement, so I can measure high-side or low-side currents without worrying too much about the common connection on my scope
    • Selectable or automatic power source selection, between circuit-powered and externally-powered

    I haven't seen anything like this in a few targeted searches, and just wondering if someone has any suggestions I might have missed.
