    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.

    Celebrate or Not: Bin Laden's Death - Thoughts?

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

    What can you do for fun with a multimeter?

    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.

    What can you do for fun with a multimeter?

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

    What can you do for fun with a multimeter?

    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.

    Bust out some rockin' beep jams on the connectivity tester! :D

    Exploring Grounding in Car Circuits: Benefits and Function Explained

    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 What evidence supports the hypothesis that dreams are false memories?

    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 What evidence supports the hypothesis that dreams are false memories?

    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...

    Build Parallel Basic Circuits with Affordable Capacitors | Learn How Here!"

    "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 PCBs 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...

    Build Pulse Oximeter: Subtract 4.5V Bias for Voltage Change

    What's your supply voltage? http://www.national.com/ds/LM/LM124.pdf 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 "rail-to-rail" Op-AMP
