DynoHubSolarPowerCombo

Introduction

As a bike tourist and commuter over the decade(s), the combination of a solar panel on the back bike trailer or paniers, and a dynohub generator on the front wheel sounds like an optimal synergy...

The XO's screen that works in direct sunlight is optimal for outdoor applications and considering how to fasten to the front of the bike (bar ends suggested) for a computer controlled next generation MicroShip Winnabiko type Linnabiko to be called XOBikePowered?...

Applying to Contributor Program

User:DancesWithCars will be applying with this idea to the Contributor program (and possibly elsewhere like dynohub manufacturers) for hardware and support.

Most people would not want someone taking apart a loaner XO machine, and the power experiments could fry stuff, so probably left over or broken parts, able to test what happens. The power output on the dynohub may be unsteady depending on spead and wide ranging.

The XO's 2 Watts is not a lot for a laptop usually in the 10 Watt range, but will see if can generate that biking and with occasional solar assist...

Sun Light and Other Limitations/ Issues

Given the occasional/ usual lack of sun in thus part if the NorthEast USA and necessary power requirements while bike touring (sometimes stopped at a paid campsite just for the power (and showering)), instead of a national parks like C&O Canal Hiker Biker camp sites...

Batteries are heavy

Weight to power ratio to consider

12V Sealed Lead Acid (SLA) motorcycle battery? Same Voltage as the car adapter? Amperage? Capacity?

Try recharging with solar panel(s) and dynohub?

Add options to charge standard batteries as well, likes packs of NiMH AA/AAA or other size standard cells?

Direct to bike running lights? Store excess? Or charge later?

Power management necessary...

Making Waterproof/ Resistant

Electronics don't want to get wet, as they stop being fun after that... Looking for a food storage box to put electronics in. Maybe a hard mil surplus ammo case? If trailer goes rolls over, then not likely to break, but high metal weight (though batteries are heavy too) and conductive, so must line it somehow?...
