    Never been so overwhelmed with work since I lost my job.

    4 of 4 models of automated blood pressure cuffs fail to read my BP

    Terrible, by my experience.

    Molds in Front Loading Washing Machine

    We do exactly that, but the softener is still an issue. Thanks, I'll try that.

    One pin AC connector (Coaxial)

    DC power is quite a rabbit hole. For any connection you need to consider arcing (welding kind/intensity) by default, since there are no 'zero crossings', but you have to be ready for plenty of inductive stuff.

    Are these rabbit pellets???

    Those droppings are special kind (not the common everydayhour ones), and you won't find them (unless you keep rabbits on grated floor). You see - rabbits eats those and don't leave them around... ... suspicious. Too small and too many, and both the color and the shape is borderline... I would...

    4 of 4 models of automated blood pressure cuffs fail to read my BP

    It's preferred to properly sit down and organize your stationary/rest position/status before measurement. May take some minutes, and might be hard to do in a kiosk. BTW those minutes are often omitted by medical staff too. ...you can try to do an experiment: measure (and record) multiple...

    Molds in Front Loading Washing Machine

    We have one. Requires regular cleaning against mold: but it's not the drum or the gasket, but the detergent-feeding compartment is what seems to be the most vulnerable spot. Quite difficult to clean it properly.

    Why do my 2-pin TV and HT systems give shocks on ports when ON together?

    Check what happens if both devices connected to the 'other' socket (with a T-plug or similar). Check (when it's unplugged) the resistance of the PE of the extension board. Check if the 'idle' voltage on the devices changes when just one device is connected (requires a voltmeter). Tweaking with...

    Fukushima Japan Earthquake: nuclear plants Fukushima part 2

    Quite strange to see this environment without the usual radiation artifacts... I wonder whether they have some software for that, or it's the situation what improved so much.

    Why do my 2-pin TV and HT systems give shocks on ports when ON together?

    Due EMI reasons most appliance power supplies contains some symmetrical capacitors to the ground, or in absence of ground (double-insulated device) to the chassis: In absence of ground this means the chassis will be on half-line voltage (high impedance source, not dangerous). The first thing...

    Kitten raising advice

    A bit worse than that, at least in the present context: the investigation was based on only two week long periods. What is that 'scienceinsights' thing, actually?

    Kitten raising advice

    Not an article about the effectiveness of bell collars. Regarding the scientific status of the matter you should take a look at the relevant wiki article (not primarily as a direct source, but as a general insight on the 'depth' of the sources available...) Species in different environments...

    Kitten raising advice

    Some cats has it (the genetics part of hunting dangerous or bigger prey) in them (consequently sometimes half the street has it in them...), but in general hunt of this kind does not happens too frequently.

    Kitten raising advice

    It's kind of similar as how cats are with rats. Happens, but not too often - the disparity is not big enough, and an adult cat can do some really ugly work on the front parts of a fox, so an experienced fox will rather think twice... These issues are lot more complicated than just those...
