Right got my wheels built for the ogre and I’m using a sp pd8 disc dyno hub and was wondering what others have used and got on with, when it comes to usb charger and lighting systems run off the dyno?

One of these will work if you’re simply charging during the daytime.

Simplest option would be something like the Busch & Muller Luxos U, it has USB output built in.

scotchy diodes, buck voltage regulator and some caps!

+1 with CraigW B&M Luxos or eWerk read the Luxos spec to see if it suits your needs

Revo for Light and A Plug 2 have been faultless so far
New build will incorporate a Sinewave, but only because I have a carbon fork that doesnt have a steerer hole

That Luxos light; €110 from ze Garmans. Noice. 🙂

Or the AXA luxx for £60 inc. postage @ rose bikes.

Is it possible to run a plug 111 and use that to charge my phone during the day and then use an exposure usb cable to power my diablo or if i get a revo to power that?

Yes, the plug will do that.

Been running my dynamo setup for over a year now when bikepacking. Wrote about my setup here: http://www.composite-projects.co.uk/2014/09/dynamos-lights-power-on-the-trail/
