Amusing! Thanks for sharing.
-
nice : ) I guess the radio doesn't take much power
-
where can I buy a dynohub ??
-
I have tested my Sturmey Archer and connected it to my electric drill.
It gave up to 80 volts ac.
This must be about the maximum you can get out of it i guess.
Does anybody have a little plan on how to make your own bridge rectifier. a drawing what to connect to what.
Thx already and keep building guys.
Greetings from Belgium

Im currently restoring an old 1960's royal enfield bike with one of these hubs on the front wheel and want to try and use it to power the bike lights. i have very limited knowledge about electricals of any sort do you have any advice about what parts/wires/lights i would need, i want to set up a front and rear light. any help would be greatly appreciated!

Hi there, If you are using proper dynamo lights then you will need to connect one terminal of the dynohub to the bicycle frame. The other terminal should be connected to a cable that runs to the lights. You will need 12 volt bulbs, I cannot remember the wattage but if you start with 2w each and see how that goes. (If they are too dim you can always replace them with lower wattage ones)

I have found a dyno hub, can you list the details of the other parts IE the bridge rectifier and condensor please (rs component catelog numbers would be useful)

Hi there, I cannot remember the exact values. But any bridge rectifier should do. With the condensor, look for an electrolytic that is around 20v and about half the size of an AA battery. (I have no Idea why your comment has been marked as spam)

Sturmey Archer do not make them any more, but you can find them still attached to old bicycles at tips and scrapyards if you are lucky. There are other companies that make their own versions, and they also turn up on Ebay fairly regularly. Happy new year.
