minus-squareThe Pantser@lemmy.worldlinkfedilinkarrow-up2·7 个月前But what powers the wheels? Charged by spinning? What happens if they don’t get used long and the wheel dies.
minus-squarenulatium@programming.devlinkfedilinkarrow-up1·7 个月前By spinning yes, they operate mostly passively and therefore last a long time, including by having terrible security to save battery life. https://www.youtube.com/watch?v=iprBprAFXCk
