Hello everyone, I bought a bottle dynamo for my bicycle with a rear and front light. Though I have one little tweak that I would like to add and that’s a way to keep it light up for about 1 minute (at least 30 sec) without pedaling. I thought of putting a capacitor in the circuit to store some energy but I would like what do you all think of it ?

Thank you for your time and have a nice day you all !

    Your solution may very well also work, good thinking. A few things to consider though:

    • Putting capacitors in series requires balancing them
    • A silicon full bridge rectifier drops ~1.4V frm the input
    • Incandecent bulbs require a lot of current to get going, this may result in a delay for them to turn on

      Ok, I forgot the voltage drop =\ I got LED light so should be fine. What I should do is put your circuit to the test without the capacitor and check if the voltage is low enough for the capacitor to handle ? How should I balance the capacitors ? (Even if I will not take this path, I would like to know)

      Thanks again for your help
