Presently panic alarm works with battery so i need to make it batteryless can any one suggest where the portable button device needs to work without battery.
What's wrong with using a battery?
Do you want to plug it into a wall outlet instead? I hope you like long extension cords.
So you plan to have a panic device that is powered by something you have to shake to make it work????for storing the power i thought of using a super capacitor bt i need only to power the device by using a alternative source if possible a circuit diagram
ha! best answer.A loud whistle, to be blown by the user?
or screaming.ha! best answer.
What power source did you intend to use? Movement? Solar?i jst have a device that works with battery i need to implement that without using a battery for storage device i thought of using a supercapcitor and for energy i thought of using a nano wire technlgy
