    Calculators Texas ti89 or casio classpad 330

    Do any of you guys still really use dedicated pocket calculators? I find myself doing all my math via PC, mentally, or using my iPod touch. It's quite rare that I ever use my TI89 any more.

    Celebrating Death

    I play dead pools so I'll celebrate if certain notable people that I like die.

    Fun with a mutimeter

    one of you contribute to PF so you can have an avatar and I can tell you apart. That seems likely, but people have weird beliefs about distilled water, it has elements of plausibility enough that someone might actually try it.

    Fun with a mutimeter

    No. Seriously, one who follows your instructions is very likely to break their multimeter.

    Fun with a mutimeter

    I sure as hell wouldn't do that with my multimeter. Do not submerge any electronics you want to keep in water unless they are waterpoofed, even if it is distilled water. Also, I don't believe your account makes a lot of sense.

    Ground in a Car Circuit

    That's what ground is, ground is the place you connect everything to. Most electrical systems have a ground that everything connects too. There are some exceptions, and those occur when having a single common ground is infeasible, (for example, the power grid can't make a ground that spans...

    Medical Are dreams experiences?

    I'll reply more later, but I should quickly point out a couple things about Dennet's speculation: 1. Dennet acknowledges his evidence isn't that compelling, only that it seems to fit with a lot of what we observed about dreams 2. Dennet is talking about this more to talk about reports of...

    Medical Are dreams experiences?

    Well, the idea here is to take the falseness up a level. Normally we think that when we wake up we have real memories of dreams, dreams being real experiences of false events when we sleep. Dennet's alternative is that the memories themselves are false, and that we do not actually dream...

    What type of capacitor?

    "Parallel" refers to the position where a capacitor is in a circuit, it's not a property of a capacitor in itself. When specifying a capacitor, the three most important basic properties is how high of a voltage you can put on it, if it's bipolar or not, and what the capacitance is.

    Can multilayer PCB have different width and/or length layers to create a shelf ?

    I have not (I have designed and ordered several PCBs in both a professional and hobbyist capability from a number of different vendors). I'm not sure how hard it would be to get a manufacturer to do it, obviously if you've got enough cash someone will figure it out, but I would suspect it...

    Medical What makes my consciousness mine ?

    An Interesting Counter to Dennet and Hofstadter's highly reductionist views would be that of David Chalmers (who in fact was a former Hofstadter student). For anyone reading too much of Dennet and Hofstadter (which is easy to do, because they're both quite good), The Conscious Mind might...

    Voltage subtractor

    What's your supply voltage? http://www.national.com/ds/LM/LM124.pdf [Broken] If you look at page 4 it says at 5 volts the Input Common-Mode Voltage range is Vsupply−1.5V, if your voltage is too your op-amp won't work properly and you need to either change your circuit or get a...
