minus-squaremesa@lemmy.worldlinkfedilinkEnglisharrow-up0·16 days agoI wonder how much we really need for a clock (555 eq) to work?
minus-squarepiecat@lemmy.worldlinkfedilinkEnglisharrow-up0·16 days agohttps://www.ti.com/lit/gpn/LM555 2mA minimum, and that’s just q current. It’s gonna be much higher when you’re actually using it for a clock. I’m sure the casio’s main power sink is the display. I bet the refresh rate could be reduced for better battery life.
