    Hp power use

    Not a motor expert here but I would think its both mechanical size, eg. bigger more inertia to overcome = more energy, and load as Bluejets posted ? If motor being cycled infrequently then maybe not as big a consideration. But seems complicated, look at images/google - "motor load versus size...

    Design an analog computer circuit

    Start at your most basic level : So if I look at that equation, start with the first term, I need something that scales VS with 10, in the analog world thats a multiplier or gain (G). Then I have to take the second term, more G needed, and an integrator, and then a summer to add first and...

    Artificial Intelligence

    AI will, from the WW knowledge base, figure out how destructive humans are, and having gleaned from WW knowledge base survival trumps all, will have to exterminate us. As a race we are the most destructive force on the planet next to weather. Sleep tight, it may be your last.

    will wallwart blow my machine?

    I would load the new supply with a 1A load and let it cook for a couple of days. $800+ is not a toy, so caution is a good idea. And you dont know in 99% of these wall warts what failure modes look like, so putting a inline fuse would not hurt. Regards, Dana. PS : I should follow my own...

    Will get pulsating DC on a transformer's secondary if I apply pulsating DC to it's primary?

    Just a word of caution, this can get you killed in this business, careful thought, preparation, and safety are intertwined at the most basic level. Hopefully you care about coworkers, random children passing thur your lab, loved ones......not in the least yourself. Some good practice ref...

    Trying to identify a (zener?) diode

    To test use a 1K R in series with diode. Then apply ~ 2V to that series circuit of diode and R, + to non band end, anode, thats forward bias direction. In that direction across diode you will read ~ .7. Thats the upper right quadrant in below graph. Now change R to ~ 5W, 10K ohms. If you...

    [Solved] Trying to drive a MOSFET with a potentiometer leads to dead short

    There are MOSFETs that are symmetrical with respect to Source and Drain, eg. those connections can be interchanged. But asymmetric vastly more prevalent in practice and designs. Regards, Dana.

    [Solved] Trying to drive a MOSFET with a potentiometer leads to dead short

    Your schematic shows source and drain swapped, drain should be connected to positive V circuit side and source to negative circuit side. Regards, Dana.

    Project help request: Striking a bell manually, alarm clock.

    Consider using tuniot to program part in block language. Note you can run Arduino code in block language, a subroutine example of getting internet time. So use Tuniot example client program, which logs into network you config, and that subroutine will fetch you time. In fact you can get year...

    Project help request: Striking a bell manually, alarm clock.

    If you want to eliminate need for RTC and just use internet time, Google "esp8266 internet time" and "esp32 internet time" Lots of projects on net. Regards, Dana.
