    Double voltage from lithium battery

    It's a micro-fan for air displacement that needs a OFF / Low Speed / High Speed control. Power of the fan is about 0.25W and it's nominal current consumption is 0.08A. Thanks for all your inputs!

    Double voltage from lithium battery

    Thanks for all your input, but the issue here is not of power consumption: - The 3V lithium battery could possibly be replaced by 2x 1.5V BUT that would be even worse in terms of voltage stability since the alkaline batteries are very bad at that. - The parallel/series suggestion is not...

    Double voltage from lithium battery

    I'm trying to create a very simple circuit where you have the following main components: 1x 3V lithium battery, 1x 3-positions switch (ON1-OFF-ON2), 1x fan (which can run from 1.5 up to 3V). I want to create a circuit where my fan can have a high speed (ON1) at around 2.5V and a low speed at...

    zener diode voltage divider

    Why does people keep saying that Zener diode are not available below 2.4V? If you go at Digikey, you can find Zener diode as low as 1.8V.
