  2. Closed: Re: Runtime of clock using alkaline D cells instead of AA batteries

    15000mAh / 2400mAh = 6.25
    60days * 6.25 = 375days

    How this compute :D

  4. Closed: Re: How can I tell if my laptop screen is LED or LCD?

    Of course, Klaus, but with a price tag the OP's question would be irelevant :smile:
  5. Closed: Re: How can I tell if my laptop screen is LED or LCD?

    Your laptop has LCD panel (as every laptop has).
    Difference is only in backlighting. It can be LED or CCFL.
    In last couple of years, all laptop panels are with LED lighting.

    Closed: Re: PT100 interfacing with controller

    220 Ohm is approx. 315 degrees C.
    You should try different approach for measuring with Pt-100. Connect it to 1mA constant current source and then measure/amplify voltage that dropped on Pt-100.

    Welllll... you should use some medicine for your memory :-) :-D
    I usually remember what some of PCB's are for, BTW I design them myself, even after years laying in the drawer.

  17. Closed: Re: Sine PWM calculated with pic, instead of using table

    In PICBasic and Proton Basic, HPWM is related to hardware PWM module in PIC micro, which directly sets registers of PWM module, leaving micro to do other work.
