    Do standard calculators have a reciprocal key? Pretty basic math wouldn't think one would need a scientific calculator.

    All I have is two old TI scientific calculators

    I just open the calculator app on my iPone and turn the phone sideways, instant scientific calculator that has a reciprocal key, as well as some other functions that occasionally come in handy.
    It isn't that the math is hard, it's just faster to input directly and hit "=".

    Same for psychrometrics calculations.
    Sure, I could take all the measurements, then sit down and plot everything out on a chart, then do the math on paper.
    Or I can open up Psyclone on my phone and input the measurements as I take them, and have the results instantly.

    It really is not a hard choice, I've got **** to get done, so the phone app wins every time.
    If more government is the answer, then it's a really stupid question.

    Mounting caps terminal side down stops water from collecting on the top and shorting them out. I give the tech credit for knowing how to obtain the 7.5 mfd but it does look very unprofessional.
    Still Crazy after all these years.

    According to AmRad, the preferred mounting direction is with the terminals up.

    There shouldn't be any water collecting on the top....

    I must admit I have made up a capacitor many times when your 300 miles from a supplier and the customers ice cream is running out the door you have to do something...

    What is duct tape actually for, and why did they call it duct tape to begin with?

    Although I have seen ducts made of duct tape, so maybe that is the reason.

    I wonder if they charged big bucks?

    And if it was a better choice quadrupling the time spent-at least making cheesy terminal connections when the correct cap was less than the price of two?

    Sometimes people work too bleep hard to be stupid!

    I'm sure hacks will hack on, earning beer money, pretty decent beer money at that for folks who are only looking at price. I always educate on what I am doing and why it is the way to do it when I work-when the homeowner watching. You don't have to say anything bad. I don't. I just keep educating and informing and planting land mines. So it may make people think twice about having the $peanuts a call guy, or their brother in law, or their neighbor who has been to school but just doesn't have gauges..... touch their equipment.

    Would you trust your car to a half wit who puts things together with duct tape for $peanurts a call or something like that? Or could you see that having someone with the right tools, skills, etc. should be working on that multi thousand dollar system you depend on for your life and comfort?
