Comment on What's the best way to add a battery like device to a dynamo light

What I wanted to do was something like thatIMG_20240925_092655

Though you seem to have a better knowledge and better circuit. I bought 2 super cap 5.5v so I wanted to put them in series (though get half the capacitance). Your approach seems to be better and I may take it. Though mine should be working ? Keep in mind that I’m a nooby in electronics and I keep learning from the internet so not the best to have solid base…

Does your solution works with 5.5V, the 6V dynamo does not blow it ?

Thank you for your answer I really like it.

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
