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 !
I should have put the stuff I have, so here you are : Dynamo : https://www.axasecurity.com/bike-security/en-gb/products/lights/7/93903195SC/axa-hr-traction-right Rear light : https://www.axasecurity.com/bike-security/en-gb/products/lights/7/93929195SC/axa-juno-e-bike-6-12v-80-mm Front light : https://www.axasecurity.com/bike-security/en-gb/products/lights/7/92520095SB/axa-nxt-60-steady
Indeed it seems like a great project I think the output is DC though I’m not sure. To be honest I tried to put a capacitor (50V) put it seemed to had no effect (maybe to little capacitance or more probably the coil of the motor should have eaten the storage. Is probably should add a diode to the circuit, am I right ?

Indeed, 2 pair of 2 wires so 4 wires can be connected to the dynamo.
I will try that, I need to find some proper diode then find the capacitor or buy it and I should be good. I’ll keep you in touch if I manage to find the parts. Thank you
Excuse me if I’m wrong but the description of your front light says in the first sentence: "The AXA Nxt 60 is a dynamo front light […] with a Steady light function allowing you to have 4 minutes of light when standing still. " Is that not already what you want?
Really good point, though as a stupid human I didn’t understood what was the difference between the Nxt 60 steady and the Nxt 60 E bike… Now I know. I don’t have this marvelous option =\ explaining why the back doesn’t light up either… Thank you for pointing it out, I couldn’t get the article from the site itself so I took another seller and it was not available (it is now)
Your typical bike dynamo puts out 6V AC. I bet yours does as well, so that diode sounds like a good idea.
Seems bad so, I have to make a diode bridge rectifier so =\ need to scrap more diode ! Too bad as I wanted to make something small
