    help with IR2110 chips

    so again 1) does anybody know the order to turn on the signal to the IR2110 inverter, turning on the inverter with the 12v and then turning on the voltage to be inverted,? I need to know because I don't want to blow anything! 2) can anybody tell me how to invert the positive and negative with...

    help with IR2110 chips

    so I'm looking into my op-amp question and it goes on about inverting signals, can you invert the dc current from negative to positive without having a signal ie wave? so when I measure the stable voltage of -55, then I want it to be +55 stable voltage when measured after the opamp there is a...

    help with IR2110 chips

    I got this from an exerpt "You can convert positive voltage to negative voltage using an inverting amplifier circuit. This circuit uses an operational amplifier (op-amp) to invert the input voltage signal. By connecting the input signal to the inverting input of the op-amp and applying feedback...

    also I have it in my head that you can change the polarity of a voltage source using an op-amp, is that right? if so how??

    help with IR2110 chips

    ok noted thanks Alec_t. Any body else have the answer for when to turn on the IR2110 circuit (with 12volt) and when to turn on the dc voltage source 55volt (to be inverted)

    cool, thought it might, also do you know the order that I should connect tbe inverter to the voltage I want and the 12v to run the inverter and the arduino signals please

    help with IR2110 chips

    so before I hook up the inverter I have a few questions, which order do I put the signals into the inverter put the 12v that powers the circuit and also when do I put in the 55volt dc that needs inverting? also do I ground the arduino with the IR2110 circuit setup, intuition tells me yes thanks!

    I don't know but I'm going with the 2uS, we'll soon find out weather or not it works out well.

    will this code suffice

    help with IR2110 chips

    I think this will work, what do you recon? #include <TimerOne.h> const int pwmPin1 = 9; // PWM output for signal 1 const int pwmPin2 = 10; // PWM output for signal 2 const long frequency = 50; // Frequency in Hz const long period = 1000000 / frequency; // Period in microseconds const long...

    from my schematic (that works) I think it's 1u second but want to make sure I'm correct! actually the dead time in that schematic is 2u seconds

    help with IR2110 chips

    is that the ton/off or the delay matching or am I looking at the wrong part? what is another way of saying dead time because when I ctrl F "dead" nothing comes up!

    help with IR2110 chips

    so progress has been slow but I'm now programming the IR2110 pulses with arduino, and can't remember the dead time if it's 1 nano-second or micro-second but think it is micro-second could you remind me?

    Maxwells demon and Maxwell's robot decrease entropy!

    and by the way, bob means number 2!

    Maxwells demon and Maxwell's robot decrease entropy!

    what do you think about that then?

    Maxwells demon and Maxwell's robot decrease entropy!

    and also the stuff about forgetting seems like bull, and I'll explain, you don't remember what time you went for a bob 4 days ago who cares anyway! surely remembering to forget takes more energy, and heat dissapation.

    thats like saying that the demon needs food and that needs to be taken into account! But it isn't in the original thought experiment!

    Maxwells demon and Maxwell's robot decrease entropy!

    so if it were made energy efficient then the entropy would still go up but more slowly?

    also if the hot molecules and cold molecules on either side of the door never increase or decrease how can the robot have extra energy to dissipate? and in the example in this video the door is massless and the only dissipation is the memory getting re-set when forgetting the information!
