   Low Frequency Noise USB Power source:

   This could be neat for a maple or lillypad arduino or for sensors.

   The systems here work good for 3v charging 5v would be awsome for a USB jack that charges itself and will discharge in your mp3 player when it is low.

   I have seen buck boost chips and energy harvesters...
   Now a TI Low Frequency Transever that can charge lipol batteries looks very interesting.
   I am allready building parts of it in kicad.
   Most of the examples show 3.3v what should be done to allow for 5v battery output for a 5v system 3.3v is most of my equipment but if it was to charge things that had a usb connector like cellphones mp3 players etc. how should that be done any sugjestions?

   TMS37157
   LTC3108
   linear design note 483
   LTC3109
   LTC3588-1
   LTC4070

   So what chip combination would work best
   what about allowing for a solar panel and pizio wind vibrated generator to be plugged in and charge a lipol so 5v could come out when someone plugs in their usb device?

   I think I will use a open source minty boost circuit hooked to the batteries switching in or out the LF charger circuit it is simple and streight forward.

   So which chip combination you have tried.. I am working on similar sort of USB power source and need a perfect chip system..Hope you will be able to help me out..
