Nick:

That is a good find!  Heck, the solar panel might cost near that alone.

Well done.

i have just been playing with some axial inductors insted of the toroid seems to work very well.
i had 4 leds at full brightness on 1ma draw that was until i went to make the unit perminat and put to much heat on the inducters upps.
any how some more are on order varying uh and hopefully this would be a good way to go as we know exactly the uh of the coil and have more control over the hurtz range.
just need to work out internal resistance of batterys hopeing a cap in parallel with the battery will bring this to a set amount.
i was thinking if we use the axial inductors we wont have wine at lower hurtz range and so can lower it but still above the lvl the eye can see and hopefully bring the current draw down further i guess the other thing is bring the voltage down also but that always depends on how well the transistor performs i think my record is 0.35 volt 1ma but that is with axial inductors have one at moment but the inductors are to low of uh to work well so the current draw is 150ma but work well for a bright tourch not concerned about length of run time with this perticaler tourch so works well.

the leds were in series btw with a cap and diode i was getting 30 volts into a 10uf 50volt cap
