makes the project much more complex, though, as the charge levels needs 
to be monitored to avoid overcharging and there needs to be a way to 
switch source from the dynamo to the battery when standing still. 
Hopefully Iíll find some time to put it together over christmas.<br>
At the end of the day though, the main problem is how much current the 
dynamo can generate. Based on some crude measurements, Iím getting 
around 300-400mA out of this circuit at ~25km/h. Thatís not even really 
enough to charge the phone on its own, let alone together with 
batteries. Perhaps there is a way to draw more current or, as Arend 
suggested, improve the efficiency of the circuit above."</p></blockquote><br>ack!<br><br>rev<br><br><div class="gmail_quote">On Fri, May 31, 2013 at 1:37 PM, Mitch Altman <span dir="ltr"><<a href="mailto:maltman23@hotmail.com" target="_blank">maltman23@hotmail.com</a>></span> wrote:<br>
