What you really want is called a DC to DC converter.

Make sure the device is properly regulated before you hook it into
anything electronic; These converters are really controlled voltage
multipliers that when malfunctioning can produce voltages in access of
2000+ Volts.

schematic for a higher voltage one that you may be able to modify

See if that gets you anywhere, you might be able to Cannibalize a
transformer out of a old sony walkman or something.
