    PID Control of an Induction Cooker.

    This is what I mean, both these signals have a period of 1 second but different on times. Adam

    PID Control of an Induction Cooker.

    I thought your minimum period was 1 second so how can you have a steady 0V? adam

    PID Control of an Induction Cooker.

    When you say PWM fully off do you mean it is switched off? Adam

    PID Control of an Induction Cooker.

    At what PWM timings would you like it to turn off. Adam

    PID Control of an Induction Cooker.

    Hi Endre What PWM timings can you output from the PID i.e. on and off timings. Adam

    Non-changing current with C-EMF

    What part of this are you having problems with. Explain your issues, dont worry I have to ask questions sometimes 100 times before I get it . Adam

    Designing a Time Delayed Relay

    Wow that looks brill. John you have come a long way. I hope this works for you. Adam

    does this seem right?

    This is why I keep coming back. Kris that is supa dupa. Adam

    A bit of physics

    We got a different answer to you, where did we go wrong? I used 1/2*mV^2 = 0.5*1000*(26.8^2) = 359*10^3 Joules = 359*10^3/50=7.18 seconds. Adam

    A bit of physics

    F=ma = m*(dv/dt) So if the velocity changes, which it must do over some time then this times the mass must change the force. Adam

    A bit of physics

    You don't need to factor in the force. You did it right. I make it 359,000 J to move the car up to a velocity of 60MPH (26.8 m/s) in one second, but you don't have enough energy for that. So yep divide the required energy by the energy you have and it works out at 7.2 seconds. Adam

    How to prevent a capacitor from dischargeing back into my circuit?

    What switch are you thinking of using?

    How to prevent a capacitor from dischargeing back into my circuit?

    But when you switch back on to measure the voltage won't the capacitor charge back up through the diode putting supply on the capacitor before you have time to measure it? :) Adam

    Nominal voltage or actual voltage for circuit calculations.

    Yes some good points there. Adam

    Simple remote LED project - help

    NO is normally open contact of the relay, I bet you can guess what NC is? Common is the point that you would place your input to be switched. So if you put say 12 Volts on the common with the relay off, you would see 12 Volts on the NC (normally closed contact). When the relay is energised you...

    Nominal voltage or actual voltage for circuit calculations.

    Unless you use a regulator, say 5 or 9 Volts or constant current. The brightness will vary accordingly between the low and high voltage ranges. Adam

    $20 Dollar reward if you can help me solve my wiring issue

    So are we thinking that the ECM sends power to the display's white wire which enables the display. Once it has a valid signal from the lighting coil. Adam
