    Homemade capacitors, that hold a charge?

    Of course it will. thanks for correcting me. I'm staring at the formula in my head right now C = k.E0.A / d I was thinking about something else but I have no real excuse, I know the formula.

    12v In A Bathroom

    If it's a switch mode power supply you can get capacitive coupling from the mains to the output. You can get a tingle when touching the output. The current is very small, and it's usually more alarming than actually dangerous.

    Homemade capacitors, that hold a charge?

    1 sheet of alfoil, one sheet of cling film, second sheet of alfoil, second sheet of cling film. Then roll it up. Be careful that the 2 sheets of alfoil don't touch.

    Homemade capacitors, that hold a charge?

    The closer together the plates are, the higher the capacitance. Halving the distance will increase the capacitance 4 times (it's an inverse square law). cling film is far thinner than paper, so the closer plates would more than make up for a lower dielectric constant (which has a linear...

    Only if you are doing something different to what that original post said.

    Can I replace a fused UK plug with a regular plug?

    No more dangerous than anywhere else in the world.

    Can I replace a fused UK plug with a regular plug?

    If you know how to do it (or if you can get someone who does to do it for you) then it will be fine, assuming the mains voltage is appropriate. Another option might be a travel adapter. This should save you the hassle of changing the plug and should also be more legal (if your country has...

    Ah. You need to do HEX to DEC, not DEC to HEX!

    You need to post a link to the thread you're talking about, otherwise we can't help.

    Mosfet Buffer Amp Circuit Help

    What is the output voltage swing from your signal generator? Do you want a bipolar output? (I.e. one that can both sink and source current?) The best option may be an option amp driven a pair of complementary MOSFETs. You will want to set up the circuit with the lowest gain that will give...

    Perhaps as a compromise they could put it around Texas?

    Investment/Advise Required

    Great, you want me to do come up with something that will get me a patent, and you're willing to fund me as well. Cool. I guess I could give you some equity position if you're prepared to do that.

    Trumps solar wall, forget politics we should just build the thing

    Where do you live? I don't know of any country which does this perfectly. It is worth noting that many countries are trying to move away from this position, so there are clearly those who don't think it's a good idea.

    Trumps solar wall, forget politics we should just build the thing

    The only one I really have a problem with is the "mass incarceration police state", assuming this describes an unjust society. The rest just fall under the "life and liberty" stuff.

    A government can't fund anything if it can't take wealth from someone and give it to someone else.

    Trumps solar wall, forget politics we should just build the thing

    The government cannot perform any function if it can't raise the funds to do so. It must redirect private citizens funds to, say, fund the judicial system who's role is to protect the rights and liberty of the citizens. Likewise, the exercise of force, be it by means of a military, police...

    Trumps solar wall, forget politics we should just build the thing

    Countries seem to demonize immigrants when jobs are scarce I see no problem with that. Once you fall in line behind my thinking, I'll have no problem agreeing with you ;-) Government has three functions: regulation, transfer of wealth, and the exercise of force. In all three, we would...

    Resistors, Capacitors, Zener diodes... Why the funny values?

    Resistors, Capacitors, Zener diodes... Why the funny values?

    I just so happen to have investigated some characteristics of zener diodes around the zener/avalanche voltage recently (not by personally doing experiments, but in advance of it). One interesting factor is that manufacturing technique (and I guess, by extension, item by item variation) can...
