oups!
don't try it or be very carefull.
the capacitor is a 1Farad 3Volts max capacitor.
that would limit the voltage that you can put your regulator at 3V. If you go
past that voltage, you'll end up blowing up your capacitor (quite a messy
situation with electrolytic capacitor). At that voltage the ligth will be
really dimmed.
so that suggestion will not work, sorry :-(
