Ok - russian is not my strength ;)

I know a similair project in Germany, short overview here:

http://www.heise.de/kiosk/archiv/ct/2007/23/190_kiosk

Its battery buffered and exactly meant for PDA's and handys.
The article includes Printed Circuit Board mask and 
Bill of Material - for hobby electricians!
I did not make it this way, but my hand crafted toy also always dies due 
to high current ;< but as benefit I have a volt and an ampeermeter 
included.

For those who are interested I think I can send a private copy but I'm not 
allowed to post the PDF file public.
