Hi pat -

Sorry I don't have plans for the one I made. Also, this particular generator might power an x-box, but probably not the display (TV).

Thanks for testing that, jimmo. I'm still impressed with your output - I bet it has a lot to do with the 24v motor and the related points you made.

I'd consider using a cap if I was just going to output the power directly to the inverter to run a radio or the laptop while I rode the bike. It seems the inverter needs a steadier voltage than I'm...

I'm pretty sure the specs of this inverter include a high V shutoff. It definitely has a low V off.

Where might I source an appropriate capacitor that's in keeping with the budget of this project?
