Should I use a Capacitor or Rechargeable battery for my shake light? Answered
I built a solenoid and am using a neodymium magnet to produce the voltage. I can get 5 volts easily, but I don't know what to use to store it. I am using a LED with a Vf of 3.3 and would ideally like the storing device to discharge slowly. What would be my best bet: A Rechargeable battery or a capacitor?
I still need to get a rectifier, but if a Capacitor is recommended, how many farads should I be looking for?
