Subject: How can you stand carrying the power supply around?
From: Joaquim Carvalho (jdc_at_x64.com)
Date: 2003-01-14


The first I'll do when I get the jukebox is a voltage doubler to charge
the batteries from the USB cable.

All easily available ingredients:

2 or 3 MAX660 voltage doublers (200 or 300mA output current)
http://www.national.com/ds/MA/MAX660.pdf
88% efficiency
5.5V max
100mA each
SO-8 package

3 or 4 150uF smd tantalum capacitors

Any other suggestions?
