Chain sounds interesting - will explore that.

Our current approach is to add a circuit (around L200) for voltage
regulation and current limiting that would allow the output of the dynamo to
be connected to the XO[1] input jacks and hence allow charging of the
batteries of the XOs.

thanks,
Arjun

[1] XO refers to the laptop
